Various types of training programs are available to cater to the diverse needs of these professionals. These include online courses, workshops, and hands-on field training.
Online courses offer a flexible and accessible option for tree removers who may have tight schedules or limited access to in-person training facilities. These courses typically cover theoretical aspects such as tree biology, disease identification, the physics of tree cutting, safety protocols, and legal regulations regarding tree removal. Online platforms often use videos, interactive quizzes, and downloadable materials to enhance learning. Moreover, these courses can be updated easily to keep pace with new techniques and regulations in the industry.
Workshops serve as a more interactive approach to training where participants can engage directly with experienced instructors. These sessions usually focus on both theoretical knowledge and practical skills. Workshops might cover topics like proper chainsaw handling, climbing techniques, emergency response procedures, and specific methods for cutting different types of trees. The face-to-face setting also allows trainees to ask questions directly and receive immediate feedback on their practical skills.
Hands-on field training is perhaps the most crucial type of program for tree removers. This training takes place in actual work environments under the supervision of certified professionals. Trainees get the opportunity to apply their learned knowledge in real-world scenarios which could involve climbing large trees, using ropes and harnesses safely, managing team dynamics during large scale removals, and handling complex tree felling projects that require precise cuts and maneuvers to avoid damage to property or harm to people.
For those looking into a career in tree removal or professionals seeking further accreditation, certifications from recognized bodies such as the International Society of Arboriculture (ISA) or similar local organizations provide validation of their skills and knowledge. Certification often requires passing both written exams and practical assessments which evaluate a candidate's competency in various aspects of tree removal processes.
In conclusion, training programs for tree removers not only support career advancement but also play a critical role in promoting safety standards within the industry. By participating in online courses, attending workshops, and undergoing hands-on field training, aspiring tree removers equip themselves with vital expertise necessary for successful performance on the job while adhering strictly to safety guidelines which protect both life and property.
Training and certification for tree removers are crucial components of the arboriculture industry, ensuring that individuals involved in this high-risk profession are both skilled and safe. The nature of working with, and around, trees involves unpredictable variables, from shifting weather conditions to the complex biological state of a tree. Therefore, several key skills are covered during training that equip tree removers with the necessary expertise to perform their duties proficiently and safely.
One of the primary areas covered in such training is tree biology. Understanding the biology of trees is fundamental for anyone in the field of arboriculture. This knowledge includes recognizing different species of trees, understanding how they grow, and knowing their strength and stress points. Tree biology also encompasses an understanding of diseases that can affect trees, which is vital for assessing whether a tree should be removed for safety reasons or if it can be saved and treated.
Proper use of equipment is another critical skill taught during training sessions. Tree removal often requires the use of heavy machinery such as chainsaws, cranes, and wood chippers. Training ensures that operators know how to handle these machines safely. It covers routine maintenance checks, proper handling techniques, and safety features inherent in each piece of equipment. This not only helps prevent accidents but also boosts efficiency in job execution.
Risk assessment forms a significant part of the training curriculum for tree removers. Before any removal begins, trained professionals learn to evaluate the site for potential hazards such as power lines, nearby structures, or unstable ground conditions. They are trained to develop plans that mitigate risks not only to themselves but also to bystanders and property. Effective risk assessment relies on both theoretical knowledge gained during training as well as practical experience.
Finally, no training program would be complete without thorough instruction in emergency procedures. Despite all precautions, emergencies can occur due to sudden changes in environmental conditions or unforeseen complications during the removal process. Emergency procedure training teaches workers how to respond quickly and effectively in crisis situations to minimize harm to themselves and others around them.
All these skills-understanding tree biology, using equipment correctly, conducting risk assessments, and executing emergency procedures-are intertwined with one another forming a comprehensive educational foundation essential for every professional involved in tree removals. This specialized training not only protects those who work directly with trees but also serves as a preventive mechanism against potential mishaps that could have wider implications on public safety.
The certification process for tree removers is a crucial step towards ensuring safety and proficiency in this potentially hazardous field. Tree removal, due to its complex nature involving heavy machinery, heights, and unpredictable natural factors, requires a specific set of skills and knowledge that are standardized through certification. This process not only enhances the credibility of professionals but also significantly mitigates risk for both the tree remover and their clients.
To begin with, prerequisites are the initial consideration for anyone looking to get certified in tree removal. Typically, individuals must be at least 18 years old and have a high school diploma or equivalent. Some certifying bodies may also require candidates to have a certain amount of hands-on experience in tree care or a related field. This experience ensures that candidates have basic familiarity with the tools and situations they might face.
Following the completion of any required prerequisites, the next step involves preparing for and passing a certification exam. These exams generally test knowledge areas such as tree biology, diagnosis of plant diseases, safety practices, and proper removal techniques including cutting patterns and equipment handling. The International Society of Arboriculture (ISA), for example, offers well-recognized certifications that require passing an exam based on their extensive body of knowledge.
In addition to theoretical exams, practical assessments are an integral part of the certification process. These assessments evaluate a candidate's ability to safely and effectively perform tree removal tasks under observed conditions. Practical tests might include scenarios such as climbing a tree using proper gear, performing aerial rescue operations, or correctly operating a chainsaw. Assessors look for adherence to safety standards, efficiency in task execution, and overall competency in managing real-life situations that could arise during tree removal operations.
Moreover, continuous education is often encouraged or required by certifying organizations to maintain certification status. This ongoing learning can involve attending workshops, participating in additional training sessions, or completing specific courses focusing on new technologies and methods in arboriculture. Staying updated with industry standards protects both professionals and clients from the evolving risks associated with tree removal work.
In conclusion, becoming a certified tree remover is comprehensive but essential for aligning with industry best practices and ensuring operational safety. The process starts with meeting basic educational requirements followed by rigorous testing on theoretical knowledge and practical skills in arboriculture. Maintaining this certification through continuous education further underscores an individual's commitment to excellence in the field of tree removal services.
In the field of tree removal, the proficiency and safety of operations significantly depend on proper equipment training. This aspect of professional development is crucial not only for efficiency but also for ensuring the safety of workers and the integrity of surrounding property. Focusing specifically on vital tools such as chainsaws, cranes, and stump grinders, we delve into how training and certification can elevate the standards of tree removers.
Chainsaws are perhaps the most iconic tools associated with tree removal. They are powerful and effective but come with high risks if mishandled. Proper training in using chainsaws involves understanding their mechanics, maintenance routines, and safety protocols. Operators must be adept at judging which type of chainsaw is best for different tasks, be it felling a large oak or trimming smaller branches. Safety training is particularly critical; this includes wearing appropriate gear such as gloves, helmets, eye protection, and ear protection. Moreover, emergency response techniques like first aid for cuts or lacerations are essential components of comprehensive chainsaw training.
Cranes play a pivotal role when dealing with large-scale tree removals. Their operation requires a deep technical understanding to maneuver heavy loads safely. Training programs for crane operators in tree removal must cover various topics including load calculation, rigging techniques, and machine maintenance. It’s imperative that these operators obtain certifications that validate their expertise in handling complex lifts without endangering human lives or causing property damage.
Stump grinders are specialized tools used after a tree has been felled to remove the stump below ground level effectively. Handling stump grinders involves learning about different grinder models, their blade configurations, and how they interact with various soil types and root systems. Training should also emphasize protective measures to prevent injuries from flying debris.
Beyond operating individual pieces of equipment, comprehensive equipment training for tree removers should include lessons on teamwork and communication because these operations often require coordination between multiple people to ensure safety and efficiency.
Certification plays a crucial role in this sector by setting standardized benchmarks for skill levels among tree removers. It provides an assurance to clients about the reliability and professionalism of services offered while promoting adherence to health and environmental regulations.
In conclusion, focused equipment training involving chainsaws, cranes, stump grinders—and indeed any tools related to arboriculture—is indispensable in cultivating skilled professionals who can carry out their duties effectively while minimizing risks to themselves and others. Such rigorous training backed by formal certification helps maintain high standards within the industry—ensuring that both workers’ welfare is protected and clients' needs are satisfactorily met
In the field of tree removal, the importance of comprehensive training and certification cannot be overstated. This is a profession that inherently involves significant risks not only to the personnel performing the tasks but also to the public and property surrounding the work area. To mitigate these risks, stringent safety protocols must be adhered to, with particular attention given to personal protective equipment (PPE) usage and first aid preparedness.
Firstly, personal protective equipment forms the first line of defense against potential hazards encountered during tree removal activities. PPE specific to tree removers includes helmets with face shields or goggles to protect from falling branches and debris, ear protection to guard against the noise of chainsaws, gloves for grip and protection from cuts, and chainsaw-resistant clothing that can provide critical protection in case of accidental slips or kickbacks from chainsaw blades. Additionally, boots with reinforced toes and anti-slip soles are essential to maintain footing on uneven ground or when climbing trees.
Training in the proper use and maintenance of this equipment is crucial. Tree removers should undergo thorough training sessions that not only detail how each piece of PPE functions but also demonstrate correct ways to wear them for maximum protection. Regular checks and maintenance schedules should be established to ensure that all equipment is in optimal condition before commencing any tree removal task.
Besides physical protection, knowledge of first aid is vital for tree removers. Given the nature of their work, injuries such as cuts, bruises, or even more severe traumas like fractures are not uncommon. As such, it's imperative that all team members are trained in basic first aid techniques. This training should include how to administer CPR, treat wounds, manage shock, and handle spinal injuries until professional medical help arrives. The presence of a well-stocked first aid kit at every job site is a must.
Moreover, emergency response plans should be a mandatory part of training modules for tree removers. These plans help teams respond swiftly and efficiently in case of an accident by outlining clear steps to follow when an injury occurs and establishing communication protocols for contacting emergency services.
Certification programs play a pivotal role in ensuring that these safety protocols are understood and applied consistently. Such certifications often involve both theoretical learning modules and practical assessments which test one's ability to implement safety measures effectively during actual operations.
Overall, integrating robust safety protocols including extensive PPE usage guidelines and first aid training into certification programs for tree removers does more than just comply with legal requirements; it fundamentally enhances the safety culture within organizations involved in this high-risk industry. By doing so, we not only protect individual workers but also uphold our ethical responsibility towards community welfare by minimizing risk exposure during potentially hazardous operations like tree removal.
Legal Requirements: Discussing Local Laws and Regulations Affecting Tree Removal Practices
In the realm of arboriculture, tree removal is not merely a physical task but also a legislative minefield where ignorance can lead to serious repercussions. Understanding and complying with local laws and regulations is paramount for anyone involved in the process of tree removal, from the seasoned professional to the occasional practitioner.
Local laws governing tree removal vary significantly depending on geographical location, municipal boundaries, and specific environmental ordinances. Such regulations are often instituted to protect urban forestry, preserve wildlife habitats, manage urban heat islands, and even safeguard private and public property. In many cities and towns, for instance, removing a tree with a trunk diameter above a certain measurement requires a permit from city officials or an environmental agency.
The implications of non-compliance can be severe ranging from hefty fines to legal actions. More critically, illegal tree removal can lead to unintended damage to ecosystems which might take years to restore. It’s not just about avoiding punitive measures; it's about understanding the integral role that trees play in our environment —from reducing carbon dioxide levels to providing shelter for wildlife.
This is why training and certification for tree removers are crucial elements in ensuring that all activities conform to legal standards while promoting safety and efficiency. Certification programs typically educate participants on various aspects including how to correctly assess trees for potential hazards, proper techniques for safe removal, emergency response procedures, and importantly, comprehensive reviews of local laws concerning tree management.
Through certified training programs, tree removers are equipped with up-to-date knowledge about legislation changes which might affect their work. Moreover, these certifications often serve as endorsements of professionalism and reliability which can significantly enhance one's reputation in a competitive market.
For anyone involved in or considering entering the field of tree removals, understanding legal requirements isn't just about adhering to laws—it represents an ethical commitment to preserving our natural world while performing necessary urban management tasks responsibly. Compliance ensures that we do our part in maintaining ecological balance while helping cities grow sustainably.
As communities continue to expand and develop new infrastructure projects while grappling with climate change impacts; trained, knowledgeable, and legally compliant tree removers will increasingly become indispensable assets in managing urban green spaces effectively.
Training and certification in the field of tree removal provide a multitude of benefits that extend beyond the mere acquisition of practical skills. These advantages not only enhance individual career prospects but also contribute positively to the safety and standards of the industry as a whole.
One of the primary benefits of being certified in tree removal is significantly higher employment prospects. Certified professionals are often preferred by employers due to their proven expertise and commitment to following industry standards. This preference can lead to more job opportunities, better job security, and potentially higher wages. Employers trust that certified individuals can perform tasks efficiently and safely, reducing the risk of accidents and liability.
Legal protection is another critical advantage provided by certification. Tree removal can be hazardous work, involving complex techniques and heavy machinery which could pose risks if handled improperly. Certified professionals receive training that complies with current safety regulations and standards, thus minimizing the likelihood of accidents or injuries on the job. In cases where accidents might occur, having certification can be invaluable in demonstrating compliance with safety protocols during legal proceedings or insurance claims.
Enhanced credibility within the industry is yet another significant benefit. Certification acts as a mark of professionalism and assures clients that a tree remover has met predefined standards of knowledge and competence set by accrediting organizations. This credibility is crucial not only for winning contracts but also for maintaining a positive reputation in a competitive market.
Moreover, certified tree removers are often more knowledgeable about new technologies, techniques, and safety measures through their required continuing education. This continuous learning process ensures they stay up-to-date with best practices which can improve their efficiency and effectiveness at work.
Through these certifications, tree removers also contribute to raising industry standards overall. As more professionals seek out training, it fosters an environment where safety and proficiency are prioritized-reducing overall risk for both workers and clients alike.
In conclusion, while obtaining certification in tree removal requires time and effort, the advantages it confers-from increased job opportunities and legal protections to enhanced credibility-are substantial. These benefits validate the importance of training not just from an individual perspective but also from an industry-wide standpoint where such credentials help maintain high professional standards essential for safe practice.
An arborist, or (less commonly) arboriculturist, is a professional in the practice of arboriculture, which is the cultivation, management, and study of individual trees, shrubs, vines, and other perennial woody plants in dendrology and horticulture.[citation needed]
Arborists generally focus on the health and safety of individual plants and trees, rather than managing forests or harvesting wood (silviculture or forestry). An arborist's scope of work is therefore distinct from that of either a forester or a logger.[citation needed]
In order for arborists to work near power wires, either additional training is required or they need to be certified as a Qualified Line Clearance Arborist or Utility Arborist (there may be different terminology for various countries). There is a variety of minimum distances that must be kept from power wires depending on voltage, however the common distance for low voltage lines in urban settings is 10 feet (about 3 metres).[1]
Arborists who climb (as not all do) can use a variety of techniques to ascend into the tree. The least invasive, and most popular technique used is to ascend on rope. There are two common methods of climbing, Single Rope System (SRS) and Moving Rope System (MRS). When personal safety is an issue, or the tree is being removed, arborists may use 'spikes', (also known as 'gaffs' or 'spurs') attached to their chainsaw boots with straps to ascend and work. Spikes wound the tree, leaving small holes where each step has been.[citation needed]
An arborist's work may involve very large and complex trees, or ecological communities and their abiotic components in the context of the landscape ecosystem. These may require monitoring and treatment to ensure they are healthy, safe, and suitable to property owners or community standards. This work may include some or all of the following: planting; transplanting; pruning; structural support; preventing, or diagnosing and treating phytopathology or parasitism; preventing or interrupting grazing or predation; installing lightning protection; and removing vegetation deemed as hazardous, an invasive species, a disease vector, or a weed.[citation needed]
Arborists may also plan, consult, write reports and give legal testimony. While some aspects of this work are done on the ground or in an office, much of it is done by arborists who perform tree services and who climb the trees with ropes, harnesses and other equipment. Lifts and cranes may be used too. The work of all arborists is not the same. Some may just provide a consulting service; others may perform climbing, pruning and planting: whilst others may provide a combination of all of these services.[2]
Arborists gain qualifications to practice arboriculture in a variety of ways and some arborists are more qualified than others. Experience working safely and effectively in and around trees is essential. Arborists tend to specialize in one or more disciplines of arboriculture, such as diagnosis and treatment of pests, diseases and nutritional deficiencies in trees, climbing and pruning, cabling and lightning protection, or consultation and report writing. All these disciplines are related to one another and some arborists are very well experienced in all areas of tree work, however not all arborists have the training or experience to properly practice every discipline.[citation needed]
Arborists choose to pursue formal certification, which is available in some countries and varies somewhat by location. An arborist who holds certification in one or more disciplines may be expected to participate in rigorous continuing education requirements to ensure constant improvement of skills and techniques.[citation needed]
In Australia, arboricultural education and training are streamlined countrywide through a multi-disciplinary vocational education, training, and qualification authority called the Australian Qualifications Framework, which offers varying levels of professional qualification. Government institutions including Technical and Further Education TAFE offer Certificate III or a diploma in arboriculture as well as some universities.[3][4] There are also many private institutions covering similar educational framework in each state. Recognition of prior learning is also an option for practicing arborists with 10 or more years of experience with no prior formal training. It allows them to be assessed and fast track their certification.[citation needed]
In France, a qualified arborist must hold a Management of Ornamental Trees certificate, and a qualified arborist climber must hold a Pruning and Care of Trees certificate; both delivered by the French Ministry of Agriculture.[5][6]
In the UK, an arborist can gain qualifications up to and including a master's degree. College-based courses include further education qualifications, such as national certificate, national diploma, while higher education courses in arboriculture include foundation degree, bachelor's degree and master's degree.[citation needed]
In the US, a Certified Arborist (CA) is a professional who has over three years of documented and verified experience and has passed a rigorous written test from the International Society of Arboriculture. Other designations include Municipal Specialist, Utility Specialist and Board Certified Master Arborist (BCMA). The USA and Canada additionally have college-based training which, if passed, will give the certificate of Qualified Arborist. The Qualified Arborist can then be used to offset partial experience towards the Certified Arborist.
Tree Risk Assessment Qualified credential (TRAQ), designed by the International Society of Arboriculture, was launched in 2013. At that time people holding the TRACE credential were transferred over to the TRAQ credential.[citation needed]
In Canada, there are provincially governed apprenticeship programs that allow arborists' to work near power lines upon completion. These apprenticeship programs must meet the provincial reregulations (For example, in B.C. they must meet WorkSafeBC G19.30), and individuals must ensure they meet the requirements of the owner of the power system.[citation needed]
Trees in urban landscape settings are often subject to disturbances, whether human or natural, both above and below ground. They may require care to improve their chances of survival following damage from either biotic or abiotic causes. Arborists can provide appropriate solutions, such as pruning trees for health and good structure, for aesthetic reasons, and to permit people to walk under them (a technique often referred to as "crown raising"), or to keep them away from wires, fences and buildings (a technique referred to as "crown reduction").[7] Timing and methods of treatment depend on the species of tree and the purpose of the work. To determine the best practices, a thorough knowledge of local species and environments is essential.[citation needed]
There can be a vast difference between the techniques and practices of professional arborists and those of inadequately trained tree workers. Some commonly offered "services" are considered unacceptable by modern arboricultural standards and may seriously damage, disfigure, weaken, or even kill trees. One such example is tree topping, lopping, or "hat-racking", where entire tops of trees or main stems are removed, generally by cross-cutting the main stem(s) or leaders, leaving large unsightly stubs. Trees that manage to survive such treatment are left prone to a spectrum of detrimental effects, including vigorous but weakly attached regrowth, pest susceptibility, pathogen intrusion, and internal decay.[8]
Pruning should only be done with a specific purpose in mind. Every cut is a wound, and every leaf lost is removal of photosynthetic potential. Proper pruning can be helpful in many ways, but should always be done with the minimum amount of live tissue removed.[9]
In recent years, research has proven that wound dressings such as paint, tar or other coverings are unnecessary and may harm trees. The coverings may encourage growth of decay-causing fungi. Proper pruning, by cutting through branches at the right location, can do more to limit decay than wound dressing [10]
Chemicals can be applied to trees for insect or disease control through soil application, stem injections or spraying. Compacted or disturbed soils can be improved in various ways.[citation needed]
Arborists can also assess trees to determine the health, structure, safety or feasibility within a landscape and in proximity to humans. Modern arboriculture has progressed in technology and sophistication from practices of the past. Many current practices are based on knowledge gained through recent research, including that of Alex Shigo, considered one "father" of modern arboriculture.[11]
Depending on the jurisdiction, there may be a number of legal issues surrounding the practices of arborists, including boundary issues, public safety issues, "heritage" trees of community value, and "neighbour" issues such as ownership, obstruction of views, impacts of roots crossing boundaries, nuisance problems, disease or insect quarantines, and safety of nearby trees or plants that may be affected.[citation needed]
Arborists are frequently consulted to establish the factual basis of disputes involving trees, or by private property owners seeking to avoid legal liability through the duty of care.[12] Arborists may be asked to assess the value of a tree[13] in the process of an insurance claim for trees damaged or destroyed,[14] or to recover damages resulting from tree theft or vandalism.[15] In cities with tree preservation orders an arborist's evaluation of tree hazard may be required before a property owner may remove a tree, or to assure the protection of trees in development plans and during construction operations. Carrying out work on protected trees and hedges is illegal without express permission from local authorities,[16] and can result in legal action including fines.[17] Homeowners who have entered into contracts with a Homeowner's association (see also Restrictive covenants) may need an arborists' professional opinion of a hazardous condition prior to removing a tree, or may be obligated to assure the protection of the views of neighboring properties prior to planting a tree or in the course of pruning.[18] Arborists may be consulted in forensic investigations where the evidence of a crime can be determined within the growth rings of a tree, for example. Arborists may be engaged by one member of a dispute in order to identify factual information about trees useful to that member of the dispute, or they can be engaged as an expert witness providing unbiased scientific knowledge in a court case. Homeowners associations seeking to write restrictive covenants, or legislative bodies seeking to write laws involving trees, may seek the counsel of arborists in order to avoid future difficulties.[19]
Before undertaking works in the UK, arborists have a legal responsibility to survey trees for wildlife, especially bats, which are given particular legal protection. In addition, any tree in the UK can be covered by a tree preservation order and it is illegal to conduct any work on a tree, including deadwooding or pruning, before permission has been sought from the local council.[citation needed]
The protagonist in Italo Calvino's novel The Baron in the Trees lives life on the ground as a boy and spends the rest of his life swinging from tree to tree in the Italian countryside. As a young man he helps the local fruit farmers by pruning their trees.[citation needed]
Some noteworthy arborists include:
Forestry is the science and craft of creating, managing, planting, using, conserving and repairing forests and woodlands for associated resources for human and environmental benefits.[1] Forestry is practiced in plantations and natural stands.[2] The science of forestry has elements that belong to the biological, physical, social, political and managerial sciences.[3] Forest management plays an essential role in the creation and modification of habitats and affects ecosystem services provisioning.[4]
Modern forestry generally embraces a broad range of concerns, in what is known as multiple-use management, including: the provision of timber, fuel wood, wildlife habitat, natural water quality management, recreation, landscape and community protection, employment, aesthetically appealing landscapes, biodiversity management, watershed management, erosion control, and preserving forests as "sinks" for atmospheric carbon dioxide.
Forest ecosystems have come to be seen as the most important component of the biosphere,[5] and forestry has emerged as a vital applied science, craft, and technology. A practitioner of forestry is known as a forester. Another common term is silviculturist. Silviculture is narrower than forestry, being concerned only with forest plants, but is often used synonymously with forestry.
All people depend upon forests and their biodiversity, some more than others.[6] Forestry is an important economic segment in various industrial countries,[7] as forests provide more than 86 million green jobs and support the livelihoods of many more people.[6] For example, in Germany, forests cover nearly a third of the land area,[8] wood is the most important renewable resource, and forestry supports more than a million jobs and about €181 billion of value to the German economy each year.[9]
Worldwide, an estimated 880 million people spend part of their time collecting fuelwood or producing charcoal, many of them women.[6][quantify] Human populations tend to be low in areas of low-income countries with high forest cover and high forest biodiversity, but poverty rates in these areas tend to be high.[6] Some 252 million people living in forests and savannahs have incomes of less than US$1.25 per day.[6]
Over the past centuries, forestry was regarded as a separate science. With the rise of ecology and environmental science, there has been a reordering in the applied sciences. In line with this view, forestry is a primary land-use science comparable with agriculture.[10] Under these headings, the fundamentals behind the management of natural forests comes by way of natural ecology. Forests or tree plantations, those whose primary purpose is the extraction of forest products, are planned and managed to utilize a mix of ecological and agroecological principles.[11] In many regions of the world there is considerable conflict between forest practices and other societal priorities such as water quality, watershed preservation, sustainable fishing, conservation, and species preservation.[12]
Silvology (Latin: silva or sylva, "forests and woods"; Ancient Greek: -λογία, -logia, "science of" or "study of") is the biological science of studying forests and woodlands, incorporating the understanding of natural forest ecosystems, and the effects and development of silvicultural practices. The term complements silviculture, which deals with the art and practice of forest management.[13]
Silvology is seen as a single science for forestry and was first used by Professor Roelof A.A. Oldeman at Wageningen University.[14] It integrates the study of forests and forest ecology, dealing with single tree autecology and natural forest ecology.
Dendrology (Ancient Greek: δÃŽÂνδρον, dendron, "tree"; and Ancient Greek: -λογία, -logia, science of or study of) or xylology (Ancient Greek: ξÃÂλον, ksulon, "wood") is the science and study of woody plants (trees, shrubs, and lianas), specifically, their taxonomic classifications.[15] There is no sharp boundary between plant taxonomy and dendrology; woody plants not only belong to many different plant families, but these families may be made up of both woody and non-woody members. Some families include only a few woody species. Dendrology, as a discipline of industrial forestry, tends to focus on identification of economically useful woody plants and their taxonomic interrelationships. As an academic course of study, dendrology will include all woody plants, native and non-native, that occur in a region. A related discipline is the study of sylvics, which focuses on the autecology of genera and species.
The provenance of forest reproductive material used to plant forests has a great influence on how the trees develop, hence why it is important to use forest reproductive material of good quality and of high genetic diversity.[16] More generally, all forest management practices, including in natural regeneration systems, may impact the genetic diversity of trees.
The term genetic diversity describes the differences in DNA sequence between individuals as distinct from variation caused by environmental influences. The unique genetic composition of an individual (its genotype) will determine its performance (its phenotype) at a particular site.[17]
Genetic diversity is needed to maintain the vitality of forests and to provide resilience to pests and diseases. Genetic diversity also ensures that forest trees can survive, adapt and evolve under changing environmental conditions. Furthermore, genetic diversity is the foundation of biological diversity at species and ecosystem levels. Forest genetic resources are therefore important to consider in forest management.[16]
Genetic diversity in forests is threatened by forest fires, pests and diseases, habitat fragmentation, poor silvicultural practices and inappropriate use of forest reproductive material.
About 98 million hectares of forest were affected by fire in 2015; this was mainly in the tropical domain, where fire burned about 4 percent of the total forest area in that year. More than two-thirds of the total forest area affected was in Africa and South America. Insects, diseases and severe weather events damaged about 40 million hectares of forests in 2015, mainly in the temperate and boreal domains.[18]
Furthermore, the marginal populations of many tree species are facing new threats due to the effects of climate change.[16]
Most countries in Europe have recommendations or guidelines for selecting species and provenances that can be used in a given site or zone.[17]
Forest management is a branch of forestry concerned with overall administrative, legal, economic, and social aspects, as well as scientific and technical aspects, such as silviculture, forest protection, and forest regulation. This includes management for timber, aesthetics, recreation, urban values, water, wildlife, inland and nearshore fisheries, wood products, plant genetic resources, and other forest resource values.[19] Management objectives can be for conservation, utilisation, or a mixture of the two. Techniques include timber extraction, planting and replanting of different species, building and maintenance of roads and pathways through forests, and preventing fire.
The first dedicated forestry school was established by Georg Ludwig Hartig at Hungen in the Wetterau, Hesse, in 1787, though forestry had been taught earlier in central Europe, including at the University of Giessen, in Hesse-Darmstadt.
In Spain, the first forestry school was the Forest Engineering School of Madrid (Escuela Técnica Superior de Ingenieros de Montes), founded in 1844.
The first in North America, the Biltmore Forest School was established near Asheville, North Carolina, by Carl A. Schenck on September 1, 1898, on the grounds of George W. Vanderbilt's Biltmore Estate. Another early school was the New York State College of Forestry, established at Cornell University just a few weeks later, in September 1898.
Early 19th century North American foresters went to Germany to study forestry. Some early German foresters also emigrated to North America.
In South America the first forestry school was established in Brazil, in Viçosa, Minas Gerais, in 1962, and moved the next year to become a faculty at the Federal University of Paraná, in Curitiba.[34]
Today, forestry education typically includes training in general biology, ecology, botany, genetics, soil science, climatology, hydrology, economics and forest management. Education in the basics of sociology and political science is often considered an advantage. Professional skills in conflict resolution and communication are also important in training programs.[35]
In India, forestry education is imparted in the agricultural universities and in Forest Research Institutes (deemed universities). Four year degree programmes are conducted in these universities at the undergraduate level. Masters and Doctorate degrees are also available in these universities.
In the United States, postsecondary forestry education leading to a Bachelor's degree or Master's degree is accredited by the Society of American Foresters.[36]
In Canada the Canadian Institute of Forestry awards silver rings to graduates from accredited university BSc programs, as well as college and technical programs.[37]
In many European countries, training in forestry is made in accordance with requirements of the Bologna Process and the European Higher Education Area.
The International Union of Forest Research Organizations is the only international organization that coordinates forest science efforts worldwide.[38]
In order to keep up with changing demands and environmental factors, forestry education does not stop at graduation. Increasingly, forestry professionals engage in regular training to maintain and improve on their management practices. An increasingly popular tool are marteloscopes; one hectare large, rectangular forest sites where all trees are numbered, mapped and recorded.
These sites can be used to do virtual thinnings and test one's wood quality and volume estimations as well as tree microhabitats. This system is mainly suitable to regions with small-scale multi-functional forest management systems
Forestry literature is the books, journals and other publications about forestry.
The first major works about forestry in the English language included Roger Taverner's Booke of Survey (1565), John Manwood's A Brefe Collection of the Lawes of the Forrest (1592) and John Evelyn's Sylva (1662).[39]

The International Society of Arboriculture, commonly known as ISA, is an international non-profit organization headquartered in Atlanta, Georgia,[1] United States. The ISA serves the tree care industry as a paid membership association and a credentialing organization that promotes the professional practice of arboriculture.[2] ISA focuses on providing research, technology, and education opportunities for tree care professionals to develop their arboricultural expertise. ISA also works to educate the general public about the benefits of trees and the need for proper tree care.[3][4]
Worldwide, ISA has 22,000 members and 31,000 ISA-certified tree care professionals with 59 chapters, associate organizations, and professional affiliates throughout North America, Asia, Oceania, Europe, and South America.[5]
ISA offers the following credentials:
The Certified Arborist credential identifies professional arborists who have a minimum of three years' full-time experience working in the professional tree care industry and who have passed an examination covering facets of arboriculture.[6][7] The Western Chapter of the ISA started the certification program in the 1980s,[citation needed] with the ISA initiating it in 1992.[8]
The Board Certified Master Arborist (BCMA) or simply Master Arborist credential identifies professional arborists who have attained the highest level of arboriculture offered by the ISA and one of the two top levels in the field. There are several paths to the Board Certified Master Arborist, but typically on average each has been an ISA Certified Arborist a minimum of three to five years before qualifying for the exam (this can vary depending upon other education and experience). The certification began as a result of the need to distinguish the top few arborists and allow others to identify those with superior credentials.
The Master Arborist examination is a far more extensive exam than the Certified Arborist Exam, and covers a broad scope of both aboriculture management, science and work practices. The exam includes the following areas:
Another credential that is on a par with the Master Arborist is that of the American Society of Consulting Arborists, the Registered Consulting Arborist.[9] There are perhaps six hundred individuals with that qualification, and only 70 arborists who hold both credentials.[citation needed]
Arboriculture (/ˈɑËÂrbÉ™rɪˌkÊŒltʃər, É‘ËÂrˈbÉâ€Ã‹Âr-/)[1] is the cultivation, management, and study of individual trees, shrubs, vines, and other perennial woody plants. The science of arboriculture studies how these plants grow and respond to cultural practices and to their environment. The practice of arboriculture includes cultural techniques such as selection, planting, training, fertilization, pest and pathogen control, pruning, shaping, and removal.
A person who practices or studies arboriculture can be termed an arborist or an arboriculturist. A tree surgeon is more typically someone who is trained in the physical maintenance and manipulation of trees and therefore more a part of the arboriculture process rather than an arborist. Risk management, legal issues, and aesthetic considerations have come to play prominent roles in the practice of arboriculture. Businesses often need to hire arboriculturists to complete "tree hazard surveys" and generally manage the trees on-site to fulfill occupational safety and health obligations.[citation needed]
Arboriculture is primarily focused on individual woody plants and trees maintained for permanent landscape and amenity purposes, usually in gardens, parks or other populated settings, by arborists, for the enjoyment, protection, and benefit of people.[citation needed]
Arboricultural matters are also considered to be within the practice of urban forestry yet the clear and separate divisions are not distinct or discreet.[citation needed]
Tree benefits are the economic, ecological, social and aesthetic use, function purpose, or services of a tree (or group of trees), in its situational context in the landscape.
A tree defect is any feature, condition, or deformity of a tree that indicates weak structure or instability that could contribute to tree failure.
Common types of tree defects:
Codominant stems: two or more stems that grow upward from a single point of origin and compete with one another.
Included bark: bark is incorporated in the joint between two limbs, creating a weak attachment
Dead, diseased, or broken branches:
Cracks
Cavity and hollows: sunken or open areas wherein a tree has suffered injury followed by decay. Further indications include: fungal fruiting structures, insect or animal nests.
Lean: a lean of more than 40% from vertical presents a risk of tree failure
Taper: change in diameter over the length of trunks branches and roots
Epicormic branches (water sprouts in canopy or suckers from root system): often grow in response to major damage or excessive pruning
Roots:
Proper tree installation ensures the long-term viability of the tree and reduces the risk of tree failure.
Quality nursery stock must be used. There must be no visible damage or sign of disease. Ideally the tree should have good crown structure. A healthy root ball should not have circling roots and new fibrous roots should be present at the soil perimeter. Girdling or circling roots should be pruned out. Excess soil above the root flare should be removed immediately, since it present a risk of disease ingress into the trunk.
Appropriate time of year to plant: generally fall or early spring in temperate regions of the northern hemisphere.
Planting hole: the planting hole should be 3 times the width of the root ball. The hole should be dug deep enough that when the root ball is placed on the substrate, the root flare is 3–5cm above the surrounding soil grade. If soil is left against the trunk, it may lead to bark, cambium and wood decay. Angular sides to the planting hole will encourage roots to grow radially from the trunk, rather than circling the planting hole. In urban settings, soil preparation may include the use of:
Tree wells: a zone of mulch can be installed around the tree trunk to: limit root zone competition (from turf or weeds), reduce soil compaction, improve soil structure, conserve moisture, and keep lawn equipment at a distance. No more than 5–10cm of mulch should be used to avoid suffocating the roots. Mulch must be kept approximately 20cm from the trunk to avoid burying the root flare. With city trees additional tree well preparation includes:
Tree grates/grill and frames: limit compaction on root zone and mechanical damage to roots and trunk
Root barriers: forces roots to grow down under surface asphalt/concrete/pavers to limit infrastructure damage from roots
Staking: newly planted, immature trees should be staked for one growing season to allow for the root system to establish. Staking for longer than one season should only be considered in situations where the root system has failed to establish sufficient structural support. Guy wires can be used for larger, newly planted trees. Care must be used to avoid stem girdling from the support system ties.
Irrigation: irrigation infrastructure may be installed to ensure a regular water supply throughout the lifetime of the tree. Wicking beds are an underground reservoir from which water is wicked into soil. Watering bags may be temporarily installed around tree stakes to provide water until the root system becomes established. Permeable paving allows for water infiltration in paved urban settings, such as parks and walkways.
Within the United Kingdom trees are considered as a material consideration within the town planning system and may be conserved as amenity landscape[2] features.
The role of the Arborist or Local Government Arboricultural Officer is likely to have a great effect on such matters. Identification of trees of high quality which may have extensive longevity is a key element in the preservation of trees.
Urban and rural trees may benefit from statutory protection under the Town and Country Planning[3] system. Such protection can result in the conservation and improvement of the urban forest as well as rural settlements.
Historically the profession divides into the operational and professional areas. These might be further subdivided into the private and public sectors. The profession is broadly considered as having one trade body known as the Arboricultural Association, although the Institute of Chartered Foresters offers a route for professional recognition and chartered arboriculturist status.
The qualifications associated with the industry range from vocational to Doctorate. Arboriculture is a comparatively young industry.

We recently had five large pine trees taken down in our front yard. We had three bids from different tree companies. We also wanted the stumps ground as well as chasing roots above ground. Rudy was fantastic and his workers were very skilled and the clean up was exceptional. We would highly recommend them and not hesitate to use them again.
Used Rudy and All In Tree for numerous things over the last year and a half. Pricing is Competitive. Very responsive to calls and tests. I like that they're insured. Did what he said what he was going to do and when he said he was going to do it. A couple of things didn't meet my expectations and he immediately came out and made it right. I have recommended to multiple other people.
Update! 10/10/23 After they helped me last month, All in Tree Service has again saved the day! A couple of large trees washed down the creek on my property recently and one of them was lodged against the pipes that go from my house to the street. There were other large tree trunks in the creek as well and also one wedged against the supports for my bridge. The All In team went to work and within a couple of hours had everything cleaned up and removed. The pipes and the bridge are safe! I recommend this team wholeheartedly. They care about what they do and it shows. Thank you! I’m very grateful. This team exemplifies professionalism. The before and after pictures tell a great story. September 2023 I recently was fortunate enough to find Rudy and Yaremi of All In Tree Services. A very large and very high limb on a big oak tree was hanging after a storm. It was a danger to me, to my dogs and to the fence below it. I had never met Rudy and Yaremi before. They were the first to call me back when I started my search for a reliable tree service. They clearly wanted the business so I gave them a chance. I’m so glad I did. They were very impressive! Their strategy and teamwork were incredible. Clearly they are very experienced at this kind of work. I took some pictures but I wish I had filmed the whole thing. It was amazing. They roped off the limb so it would not fall on anything or anyone. Then they quickly got the limb cut and safely on the ground and helped to clear up the debris. I am extremely happy with their service and with the friendly and professional manner with which they conducted themselves. I have already recommended them to my neighbors and I strongly encourage anyone who needs tree services to call them.
All professional service. Timely, efficient, friendly. I had big old dead trees that I feared daily were going to come down. I called them in an emergency and they came the very next morning, no problem, no excuses. The guys were about service and me as a customer. They saw what I needed and went above and beyond to make sure I was a satisfied customer. I am a satisfied customer. I will use this company again and again. Thank you Rudy.
