Even a small amount of water left on the tool can lead to significant rusting over time. Therefore, after washing your tools, always dry them thoroughly using a clean cloth or towel.
Once the tools are dry, applying an appropriate lubricant is crucial. This practice does more than just ease operation; it provides a protective coating that repels water and prevents rust. For moving parts like the pivot point in shears or foldable saws, penetrating oils such as WD-40 are recommended because they reach deep into crevices. For blades, a light coat of mineral oil will suffice; this forms a barrier against moisture and keeps the metal surfaces smooth and free from oxidizing agents.
Storage also plays a pivotal role in preventing rust and ensuring longevity. Always store your tools in a dry environment. Humid conditions promote rusting even if you have cleaned and oiled your tools meticulously. If possible, hang them up or keep them in a toolbox with silica gel packs that absorb any residual moisture.
Finally, periodic checks for signs of wear or damage should be part of your routine tool maintenance schedule. Catching issues like small rust spots or dull blades early means you can address them before they become serious problems. Small rust spots can often be removed with steel wool or sandpaper followed by reapplication of lubricant.
By adopting these simple yet effective cleaning practices-cleaning after use, thorough drying, applying lubricant regularly, thoughtful storage, and routine checks-your hand tool investment like shears and saws will be well protected against rust while maintaining peak performance for years to come.
Sharpening Techniques to Maintain Effectiveness of Hand Tools: Shears and Saws
Maintaining the effectiveness of hand tools such as shears and saws is essential for both safety and performance. Over time, the cutting edges of these tools can become dull due to regular use, leading to inefficient cuts and increased effort during tasks. To ensure optimal functionality, adopting proper sharpening techniques is vital. This essay explores some of the key methods used to sharpen shears and saws, ensuring they remain in top condition.
Starting with shears, which include varieties like gardening shears or tin snips, the first step in sharpening is to clean them thoroughly. Removing any residue or rust from the blades ensures a smoother sharpening process. Once cleaned, a flat file should be used to sharpen the cutting edge. It's important to maintain the original angle of the blade edge while filing; typically, this angle ranges between 10 to 20 degrees. Using smooth, even strokes along the blade's edge ensures uniform sharpness. After filing, honing with a whetstone can refine the edge further. Finally, applying a light coat of oil protects the metal from rust and enhances its longevity.
Saws require a slightly different approach due to their toothed design. The type of saw – whether it's a crosscut saw or a rip saw – dictates the specific sharpening method needed due to differences in tooth shape and angle. Before starting the sharpening process, securing the saw firmly in place with clamps can prevent unwanted movement. A triangular file that matches the pitch and angle of the saw teeth is essential for effective sharpening. Each tooth should be filed individually by following its unique geometry; this typically involves working at an angle consistent with each tooth's design.
For both crosscut saws and rip saws, it's crucial not only to sharpen but also to set the teeth correctly (which means bending them slightly outwards alternately on either side). This setting creates a wider kerf during cutting which prevents the saw from getting stuck in thicker materials.
In addition to using files for manual sharpening, there are mechanical devices available that can automate parts of this process - especially useful for those lacking confidence in their hand-sharpening skills or dealing with multiple tools frequently.
Regular maintenance doesn't stop at sharpening; it also involves occasionally assessing your tools for wear or damage such as cracks in blades or worn handles that could affect performance or safety.
In conclusion, understanding how to properly maintain and sharpen hand tools like shears and saws is crucial for anyone who relies on these implements regularly. By adhering to appropriate cleaning procedures before sharpning , carefully maintaining angles when using files ,and ensuring all parts are securely held during maintenance activities ,users can extend their tools' lifespan significantly while ensuring they perform efficiently on every use . Remember , sharp tools are not just more effective-they're safer too.
Safety Guidelines When Using Shears and Saws
When embarking on any project that requires the use of hand tools, such as shears and saws, it is crucial to adhere to specific safety guidelines. These tools, while essential for cutting various materials, can pose significant risks if not used correctly. This essay outlines fundamental safety practices to ensure both efficiency in task completion and the well-being of the user.
First and foremost, personal protective equipment (PPE) is non-negotiable. Safety goggles are a must to protect your eyes from flying particles or sharp splinters that might result from cutting operations. Gloves should be worn to guard against cuts and abrasions-preferably those made from tough materials that offer dexterity and grip without compromising safety. In certain situations, especially when working with heavy items or in noisy environments, additional PPE like steel-toed boots and ear protection might be necessary.
Before using any tool, it's imperative to inspect it for damages such as cracks in blades or loose components. Using damaged tools not only hampers the quality of your work but also increases the risk of accidents significantly. If a tool is found to be faulty, it should be repaired or replaced immediately.
Understanding the tool's proper usage is another critical aspect. Each type of shear and saw is designed for specific materials and applications. For instance, tin snips are ideal for cutting through thin sheets of metal whereas pruning shears are meant for trimming overgrown branches effectively. Similarly, different types of saws like hacksaws, coping saws, and crosscut saws serve distinct purposes from cutting metal pipes to intricate shapes in wood respectively. Using the wrong tool for a job can result in damage both to the tool and the material, along with potential harm to the user.
The actual process of cutting should always be approached with caution. Ensure stable footing and maintain good balance during operation; this stability helps prevent slips or sudden movements that could lead to mishaps. Always cut away from your body where possible, keeping hands clear of blades at all times. It's also advisable to secure materials properly using clamps or vices which frees both hands for handling tools safely.
Workspace organization cannot be overlooked as a critical component of safe operation with hand tools like shears and saws. A clutter-free environment ensures ease of movement around projects without tripping hazards posed by scattered tools or offcuts lying around workspace areas.
Lastly, never rush when using these tools; haste not only impacts precision but also heightens accident risks significantly. Taking regular breaks during extensive projects helps alleviate fatigue which can compromise attention leading potentially dangerous slip-ups.
In conclusion, while shears and saws are indispensable aids in various tasks related to cutting different materials ranging from paper all way up through thick boards - their effective & safe usage hinges on strict adherence established safety protocols highlighted above along careful handling maintenance every step way ensuring longevity these valuable implements alongside health physical well-being users involved entire process execution their respective functions efficiently safely as possible.
When considering the topic of hand tools such as shears and saws, it is essential to address the importance of using protective gear like gloves and goggles. These tools, while indispensable for cutting and shaping materials in various industries, including carpentry, gardening, and metalworking, pose significant risks without proper safety measures.
Protective gloves are vital when working with shears and saws. Shears, used for cutting through materials like metal or heavy fabric, require the user to apply force, making the hand vulnerable to blisters, cuts, or worse if the shear's blades slip or if the material being cut is unexpectedly tough. Similarly, saws can cause splinters or severe cuts from their sharp teeth. Gloves provide a barrier between the skin and these hazards. They not only prevent direct injury but also improve grip on the tool handles, reducing the chance of accidental slips that could lead to injuries.
Goggles are just as critical when using these tools. Both shears and saws can generate flying particles - metal shards from cutting wires with shears or wood dust from sawing through lumber. Such debris can be extremely hazardous if it comes into contact with one's eyes; at best causing irritation or temporary vision obstruction, at worst leading to serious eye injuries or permanent vision loss. Safety goggles provide a shield over the eyes that keeps out harmful particles effectively.
Moreover, beyond immediate physical injuries, long-term exposure to dust and debris without protection can contribute to chronic respiratory issues or eye conditions which might manifest much later in life. Thus wearing goggles not only serves as an immediate safeguard but also acts as a preventive measure against potential long-term health problems.
Overall, integrating safety practices by using gloves and goggles while handling hand tools like shears and saws is not merely about adhering to recommended safety guidelines; it's about cultivating a mindful approach towards work that prioritizes personal safety and well-being. This proactive attitude towards safety can significantly mitigate risks associated with these powerful tools ensuring that tasks are performed efficiently without compromising on health and security.
Choosing the right tool for specific tasks, especially in the realm of hand tools such as shears and saws, is crucial not only for efficiency but also for safety. This selection process involves understanding the nature of the task at hand, the material involved, and the precision required. A well-chosen tool can significantly enhance the quality of work while reducing effort and risk.
Shears and saws are common hand tools found in many workshops, garages, and toolboxes, each designed to handle different materials and cutting styles. Shears are primarily used for cutting various thin materials like paper, metal foil, cloth, and wire. Depending on their design, they can range from simple household scissors to complex industrial shears capable of slicing through thick sheets of metal.
The effectiveness of shears largely depends on the sharpness of their blades and the leverage provided by their handles. Selecting the right type of shears involves considering the material thickness and resilience. For instance, using dressmaker's shears to cut through heavy-duty fabric ensures a clean cut without fraying - a task that would be challenging with standard scissors.
On the other hand, saws are geared towards cutting wood, metal, or plastic. They come in various forms such as hand saws, back saws, hack saws, and coping saws. Each type has a specific purpose; for example, a back saw is typically used for fine joinery work due to its stiffened rib that keeps cuts straight. Using an inappropriate saw can result in poor execution or even damage to both the material and the tool.
For precise cuts in woodworking where detail is paramount, choosing a coping saw allows for intricate shapes and turns within the material being cut-something nearly impossible with more robust types of saws designed for straighter cuts. Similarly, using a hacksaw is appropriate when dealing with metal pipes or rods because it's specifically designed to handle harder materials which would quickly dull other types of blades.
Beyond selecting between shears or saws based on what needs cutting, consideration must also be given to ergonomics – ensuring that whichever tool is chosen fits comfortably in one's hand and doesn't lead to undue strain during use. This aspect isn't merely about comfort but about control: a securely gripped tool provides better accuracy and reduces chances for mistakes or accidents.
Another point worth noting is maintenance; keeping tools like shears and saws sharp and well-oiled not only prolongs their lifespan but also keeps them effective. Dull blades require more force to cut through materials, which can compromise precision and increase physical exertion thereby elevating risk factors associated with slips or mis-cuts.
In conclusion, the importance of selecting the appropriate hand tool – be it shears or any type of saw – cannot be overstated. It ensures safety, efficiency, and quality outcomes. Each task demands specific tools tailored to its unique requirements; hence understanding these needs plays a fundamental role in achieving craftsmanship excellence. By carefully considering these elements, one can ensure optimal performance while minimizing potential hazards inherent in manual work involving cutting instruments.
The journey of mastering hand tools such as shears and saws is not just about acquiring the right tools; it's profoundly linked to regular practice and a steadfast commitment to care. This essay explores how encouragement plays a pivotal role in fostering skill development, enabling both novices and experienced users to enhance their proficiency with these essential instruments.
Firstly, understanding the importance of regular practice cannot be overstated. Hand tools like shears and saws demand precision, which is honed through repetition. Each cut made with a pair of shears or each board sawn teaches something new about technique, handling, and material properties. For beginners, initial attempts may be marked by uneven or jagged cuts, but this is where encouragement steps in. Positive reinforcement from peers, mentors, or trainers can significantly boost confidence. It can transform an intimidating learning curve into an exciting educational journey.
Moreover, seasoned professionals also benefit from encouragement. It serves as a reminder that mastery is a continuous process of improvement. In advanced stages, focusing on finer details such as the angle of cutting or the pressure applied becomes crucial. Here again, encouragement helps maintain motivation for constant self-improvement despite the plateauing of visible progress typical in later stages of skill development.
In addition to practice, care of tools is critical in developing and maintaining skills with hand tools like shears and saws. Proper maintenance not only extends the lifespan of these tools but also ensures they perform at their best. Dull blades or improperly aligned components can lead to poor execution and discourage further use due to increased difficulty and poor results. Learning how to care for these tools-sharpening blades regularly, oiling mechanisms to prevent rust, storing them properly-requires diligence that should be encouraged consistently.
Encouragement in tool care often comes from understanding their value beyond utility: these are not just implements but extensions of the artisan's hands. Workshops and classes on maintenance can serve as excellent platforms for nurturing this aspect of skill development. They provide communal spaces where experiences are shared-spaces where beginners can learn from veterans not only how to use their tools but also how to cherish them.
Finally, it's essential for learners at all levels to receive support in internalizing safety practices related to using hand tools like shears and saws effectively and responsibly. Encouragement doesn't just push individuals towards technical proficiency; it also embeds a culture of safety that protects them from potential injuries associated with improper tool use.
In conclusion, while hand tools may seem simple compared to power-driven devices, mastering them fully requires an environment rich with encouragement for relentless practice and meticulous care. Such supportive atmospheres foster growth not only in individual skills but also build communities bonded over craftsmanship excellence-an invaluable aspect that stretches well beyond the confines of any workshop or studio.
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: δÎνδρον, dendron, "tree"; and Ancient Greek: -λογία, -logia, science of or study of) or xylology (Ancient Greek: ξÏλον, 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]

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:
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.
