Calculation and Load Assessment in Rigging Techniques for Controlled Dismantling
Rigging techniques play a crucial role in the controlled dismantling of structures, whether it be buildings, bridges, or industrial installations. The process involves complex planning and execution where safety and precision are paramount. A fundamental aspect of this planning is the calculation and load assessment, which ensures that the dismantling process is not only efficient but also minimizes risk to workers and the surrounding environment.
The first step in successful rigging for dismantling is understanding the structure's design and the materials involved. This knowledge provides insight into how the structure will behave during dismantling. Engineers and rigging specialists assess structural drawings and perform site inspections to gather necessary data. These assessments help identify key load-bearing elements, potential weaknesses, and any hazardous materials present.
Following this initial assessment, precise calculations are essential. Load assessment involves determining the weight of various parts of the structure to be dismantled. This includes not only the primary structural components but also ancillary elements such as piping, machinery, and any remaining contents. It’s critical to estimate these loads accurately because they determine the choice of rigging gear and methods used.
Moreover, these calculations extend beyond simple weight estimations. Factors such as center of gravity, potential shift in load distribution during cutting or lifting, wind loads, and other environmental impacts must also be considered. The dynamic nature of removing sections from a structure means that stability can change moment by moment; thus real-time monitoring systems might sometimes be implemented to track these changes during operations.
The selection of appropriate rigging equipment is directly tied to these calculations. Cranes, hoists, cables, slings, shackles – each piece must be capable of safely handling more than just the predicted maximum load. Safety factors are incorporated into all equipment choices to handle unexpected loads or failures in other areas without causing accidents.
Another aspect under consideration in load assessment is sequencing – deciding on which parts of a structure should come down first so as not to compromise its overall stability prematurely or unnecessarily endanger areas still intact or yet to be worked on. This sequence has to align with calculated risks as well as practical considerations like disposal routes or temporary supports needed.
Once all scenarios have been modeled and equipment selected based on thorough calculations and assessments; trial runs might often be conducted especially in complex projects. These rehearses help validate assumptions about behavior under actual working conditions thereby allowing fine-tuning before full-scale execution begins.
In summary, calculation and load assessment form an integral part of rigging techniques for controlled dismantling projects—a meticulous process that upholds safety while ensuring efficiency. Advanced mathematical models combined with hands-on expertise guide decision-making right from preparation through execution phases; underscoring once again how vital accurate data collection followed by rigorous analysis is within construction engineering disciplines focused on deconstruction tasks.
When discussing rigging techniques for controlled dismantling, it is crucial to address the guidelines on how to calculate loads and stresses on rigging equipment. This ensures stability and safety throughout the dismantling process, preventing accidents and structural failures that could result in severe consequences. The focus of this essay is to outline key considerations and methods used in these calculations.
Firstly, understanding the nature of the load is fundamental. This includes knowing its weight, shape, size, and center of gravity. The weight of the load dictates the capacity of the rigging gear required. Misjudgment in this aspect can lead to overloading, which might cause equipment failure. Therefore, precise measurements and often conservative estimates are essential.
The center of gravity is equally important as it affects the load's stability during lifting or moving operations. An incorrectly estimated center of gravity can cause unexpected tilting or swaying, making the operation dangerous. Tools such as load calculators or computer-aided design (CAD) software are invaluable for accurately determining these parameters.
After assessing the load itself, selecting appropriate rigging equipment is the next step. This includes slings, shackles, hoists, and other accessories rated for at least the maximum anticipated load. It's advisable to follow a safety factor rule-commonly a factor of five or higher-whereby the equipment's working load limit (WLL) should be significantly greater than the actual load.
Calculating stresses involves considering both static and dynamic factors. Static stress calculation looks at weights and forces when they are relatively constant over time; dynamic factors come into play with movement-lifting, swinging, or any sudden changes in motion-which introduces acceleration forces that increase stress on rigging components.
For instance, when a load is being lifted by a crane on a windy day, not only does one need to consider its static weight but also how wind influences dynamic loading conditions like sway or rotational forces. These dynamic loads require careful assessment through stability analysis often supported by performance data from similar operations.
Proper communication among team members during planning and execution phases enhances safety measures further. Rig leaders must ensure all involved understand their roles clearly along with any potential hazards associated with deviations from planned procedures.
Finally yet importantly is adherence to regulatory standards set forth by organizations such as OSHA in the U.S., which provides detailed guidelines on safe lifting practices including proper maintenance of equipment and periodic inspections before use.
In conclusion, calculating loads and stresses on rigging equipment for controlled dismantling demands thorough preparation beginning from an accurate assessment of physical characteristics of the load through selection and inspection of suitable rigging gear based upon calculated static and dynamic stresses ensuring compliance with safety regulations at every step. Such meticulous planning guarantees not just success in dismantling activities but also safeguards human lives and property involved.

This approach ensures these pieces can be preserved or reused in accordance with local conservation laws.
These diverse applications highlight how rigging techniques must be adaptable yet precise across different industries-ranging from heavy engineering sectors like oil extraction to sensitive historical preservation efforts. Each case underlines the importance of tailoring rigging solutions based on structural complexities, environmental considerations, and safety requirements.
Through continuous innovation in methods such as dynamic positioning for ships involved in offshore dismantling or enhanced sensor-based monitoring systems for urban constructions, professionals can optimize controlled dismantling processes further. As each structure presents unique challenges based on its environment and function, ongoing research and development into advanced rigging technologies will remain essential.
Rigging Techniques for Controlled Dismantling: A Study of Successful Projects
Controlled dismantling projects are critical in various industries such as construction, demolition, and maritime operations. These projects require meticulous planning, expert execution, and advanced rigging techniques to ensure safety, efficiency, and minimal environmental impact. This essay highlights several case studies that illustrate the successful application of advanced rigging techniques in controlled dismantling projects across different sectors.
One notable project was the demolition of a 20-story building situated in a densely populated urban area. The primary challenge was to dismantle the structure without affecting the surrounding buildings and infrastructure. Advanced rigging techniques were employed extensively here. Cranes equipped with high-capacity slings and precision load monitoring systems were used to remove large sections of the building piece by piece.
Each segment was carefully rigged and then lowered to the ground rather than being demolished explosively, which minimized dust and debris. The use of modular spreader beams allowed for even distribution of weight and ensured stability during lifting operations. This approach not only secured safety but also significantly reduced the project's overall environmental footprint.
The decommissioning of offshore oil rigs presents unique challenges due to their massive size and remote location. In one exemplary project in the North Sea, engineers utilized advanced rigging techniques involving heavy-lift ships equipped with dual cranes. These cranes operated synchronously to dismantle large sections of the oil rig.
Specialized rigging gear including high-performance synthetic ropes offered durability against harsh marine environments while providing necessary strength-to-weight ratios ideal for such large-scale operations. Through careful planning and execution, this technique allowed for quick dismantling processes that adhered strictly to environmental standards regarding marine ecosystems.
Another fascinating application involved the dismantling of a historic bridge that needed replacement due to structural concerns but also required preservation for historical significance. Rigging specialists used a combination of traditional block-and-tackle systems along with modern dynamic load monitoring technology to ensure that each section of the bridge was removed without causing damage.
The project utilized computer-controlled winches which allowed operators to perform precise movements essential for handling delicate structures safely. Furthermore, real-time data from load sensors ensured that any potential overloading could be immediately addressed, thereby preventing structural failures during the operation.
These case studies demonstrate how advanced rigging techniques can be crucial in successfully managing complex controlled dismantling projects across various industries. By integrating sophisticated mechanical systems with cutting-edge technology, these projects achieve efficiency without compromising on safety or environmental sustainability.
From urban demolition sites to offshore platforms and historical monuments, each case underscores a common theme: meticulous planning coupled with innovative engineering solutions is key to tackling challenging dismantlings effectively. As technologies evolve so too does our ability to manage increasingly complex scenarios in controlled dismantling processes.
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:
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.
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]

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.
