Understanding policy exclusions and limitations is crucial for anyone hiring a tree care company. Essentially, exclusions define what's not covered by the insurance policy, and knowing these can prevent nasty surprises down the line. Let's talk about some common exclusions you might encounter when dealing with tree care operations.
One typical exclusion is damage to property owned by the insured. This means if the tree care company accidentally damages your house while removing a tree, their insurance likely won't cover it. This emphasizes the importance of discussing liability coverage and potentially separate property damage coverage with the company beforehand.
Another common exclusion revolves around pre-existing conditions. If a tree is already diseased or structurally compromised and subsequently falls, causing damage, the insurance might not cover it, claiming the issue existed before their involvement. This highlights the importance of thorough tree assessments before any work begins.
Acts of God, such as severe storms, lightning strikes, or floods, are frequently excluded. If a tree is damaged or falls due to a hurricane, for example, the insurance company might not cover the cost of removal or repairs. It's important to understand what constitutes an "Act of God" in your specific policy.
Willful negligence or improper work practices are also often excluded. If the tree care company demonstrably cuts corners or disregards safety procedures, leading to damage, the insurance might refuse coverage. This underscores the importance of hiring reputable, certified arborists who follow best practices.
Finally, some policies exclude specific tree species or sizes. For instance, removing exceptionally large or hazardous trees might require specialized coverage, and the standard policy might not apply. Always clarify with the company what their insurance covers in relation to the specific trees on your property.
In short, don't just assume you're covered. Ask the tree care company for a copy of their insurance certificate and discuss the policy exclusions in detail. Understanding these limitations upfront can save you a lot of headache and expense down the road.
Understanding limitations on coverage amounts is crucial for anyone navigating the sometimes confusing world of insurance. It's easy to assume that if you have insurance, you're fully protected. However, policies almost always come with limitations on how much the insurer will pay out in a given situation. These limitations can apply to specific incidents, certain types of damage, or even the total lifetime benefits you can receive. Ignoring these details can lead to nasty surprises when you actually need to file a claim.
Think of it like this: you buy a beautiful, antique vase and insure it. You might assume that if it breaks, the insurance will cover the full replacement cost. But what if your policy has a limit of, say, $5,000 for any single item, and your vase is appraised at $10,000? You'd be responsible for the remaining $5,000. That's a limitation on coverage amount in action.
These limitations can take various forms. Sometimes they're expressed as a specific dollar amount, like in the vase example. Other times, they might be a percentage of the total insured value. For example, a homeowner's policy might cover up to 80% of the cost to rebuild your home after a fire, leaving you to cover the remaining 20%. There can also be sub-limits within a policy. Your homeowner's insurance might have a general coverage limit for personal property, but a much lower sub-limit for specific categories like jewelry or electronics.
Why do these limitations exist? Primarily, they help insurance companies manage risk and keep premiums affordable. By capping their potential payouts, insurers can offer coverage to a wider range of people. Understanding these limitations empowers you to make informed decisions about your coverage. It allows you to assess your potential out-of-pocket expenses in the event of a loss and consider whether you need additional coverage, like a separate rider for valuable items, to bridge the gap. So, before you sign on the dotted line, take the time to understand the limitations on your coverage amounts. It's a small effort that can save you a lot of headache down the road.
Strategies for Mitigating Coverage Gaps: Understanding Policy Exclusions and Limitations
Insurance policies, while designed to protect us from financial hardship, are often riddled with exclusions and limitations. These are specific situations or circumstances where the policy won't pay out, or will only pay a limited amount. Failing to understand these nuances can lead to significant coverage gaps, leaving you vulnerable when you need protection the most. Therefore, it's crucial to proactively address these gaps to ensure adequate coverage.
One of the most effective strategies is to thoroughly review your policy documents. Don't just skim them; actively read the fine print, paying particular attention to sections outlining exclusions and limitations. Look for terms like "not covered," "exceptions," and "maximum benefit." If anything is unclear, don't hesitate to contact your insurance agent or company for clarification. It's better to ask questions upfront than to be surprised by a denied claim later.
Another key strategy is to consider supplemental insurance. Many standard policies have limitations on specific types of coverage. For example, a homeowner's policy might have limited coverage for valuable jewelry or artwork. In these cases, purchasing a separate rider or endorsement can extend your coverage to these specific items. Similarly, umbrella insurance provides an extra layer of liability protection beyond the limits of your primary policies, like auto or homeowner's.
Comparing policies from different insurers is also essential. Coverage, exclusions, and limitations can vary significantly between providers. By comparing multiple options, you can identify policies that offer the most comprehensive coverage for your specific needs and risk profile. Online comparison tools and independent insurance brokers can be valuable resources in this process.
Finally, regular policy reviews are crucial. Life circumstances change, and your insurance needs evolve along with them. Review your policies annually or after major life events like marriage, the birth of a child, or a significant purchase. This ensures your coverage remains adequate and aligned with your current situation.
By understanding policy exclusions and limitations and actively implementing these mitigation strategies, you can avoid unpleasant surprises and ensure you have the right coverage when you need it most. Taking the time to understand your insurance needs and policy details is an investment in your financial security and peace of mind.
Life throws curveballs. One minute you're cruising along, the next you're dealing with a flooded basement or a fender bender. That's when you really lean on your insurance. But what happens when your claim is denied? Often, the culprit is a sneaky little thing called a policy exclusion or limitation. That's why regularly reviewing and updating your insurance is so crucial for truly understanding what you're covered for – and, more importantly, what you're not.
Think of your insurance policy like a living document. Your life changes, your needs change, and so should your coverage. Got married? Bought a house? Started a business? These are all major life events that impact your insurance needs. That sparkling new engagement ring needs to be scheduled on your homeowner's policy, and that home-based business might require a separate policy altogether. Without reviewing and updating, you could be left with gaps in your coverage, leaving you vulnerable to financial hardship.
Reviewing your policy isn't just about adding new items or increasing coverage amounts. It's also about understanding those pesky exclusions and limitations. Exclusions are specific events or situations that your policy won't cover. For example, flood damage is typically excluded from standard homeowner's policies. Limitations, on the other hand, cap the amount your insurance company will pay out for a covered loss. Maybe your policy covers jewelry theft, but only up to a certain dollar amount.
By reviewing your policy annually, or whenever you experience a significant life change, you can identify these exclusions and limitations. This allows you to make informed decisions about your coverage. Perhaps you decide to purchase a separate flood insurance policy or increase your jewelry coverage. The point is, you're taking control of your risk and avoiding unpleasant surprises down the road. Don't wait for disaster to strike before discovering you're not adequately protected. Take the time to review and update your insurance – it's an investment in your peace of mind.
Horticulture is the art and science of growing fruits, vegetables, flowers, trees, shrubs and ornamental plants. Horticulture is commonly associated with the more professional and technical aspects of plant cultivation on a smaller and more controlled scale than agronomy. There are various divisions of horticulture because plants are grown for a variety of purposes.[1] These divisions include, but are not limited to: propagation, arboriculture, landscaping, floriculture and turf maintenance. For each of these, there are various professions, aspects, tools used and associated challenges -- each requiring highly specialized skills and knowledge on the part of the horticulturist.
Typically, horticulture is characterized as the ornamental, small-scale and non-industrial cultivation of plants; horticulture is distinct from gardening by its emphasis on scientific methods, plant breeding, and technical cultivation practices, while gardening, even at a professional level, tends to focus more on the aesthetic care and maintenance of plants in gardens or landscapes. However, some aspects of horticulture are industrialized or commercial such as greenhouse production or CEA.
Horticulture began with the domestication of plants c. 10,000 – c. 20,000 years ago.[2][3] At first, only plants for sustenance were grown and maintained, but as humanity became increasingly sedentary, plants were grown for their ornamental value. Horticulture emerged as a distinct field from agriculture when humans sought to cultivate plants for pleasure on a smaller scale rather than exclusively for sustenance.
Emerging technologies are moving the industry forward, especially in the alteration of plants to be more resistant to parasites, disease and drought. Modifying technologies such as CRISPR are also improving the nutrition, taste and yield of crops.
Many horticultural organizations and societies around the world have been formed by horticulturists and those within the industry. These include the Royal Horticultural Society, the International Society for Horticultural Science,[4] and the American Society of Horticultural Science.[5]
There are divisions and sub-divisions within horticulture because plants are grown for many different reasons. Some of the divisions in horticulture include:
It includes the cultivation of all plants including, but not limited to: ornamental plants, fruits, vegetables, flowers, turf, nuts, seeds, herbs and other medicinal/edible plants. This cultivation may occur in garden spaces, nurseries, greenhouses, vineyards, orchards, parks, recreation areas, etc. [citation needed]
Horticulturists study and practice the cultivation of plant material professionally. There are many different types of horticulturists with different job titles, including: gardener, grower, farmer, arborist, floriculturist, landscaper, agronomist, designer, landscape architect, lawn-care specialist, nursery manager, botanical garden curator, horticulture therapist, and much more.[9] They may be hired by a variety of companies/institutions including, but not limited to: botanical gardens, private/public gardens, parks, cemeteries, greenhouses, golf courses, vineyards, estates, landscaping companies, nurseries, educational institutions, etc. They may also be self-employed.[citation needed]
Horticulture began with the domestication of plants 10,000–20,000 years ago and has since been deeply integrated into human history.[2][3] The domestication of plants occurred independently within various civilizations across the globe. The history of horticulture overlaps with the history of agriculture and history of botany, as all three originated with the domestication of various plants for food.[3] In Europe, agriculture and horticulture diverged at some point during the Middle Ages.[10]
Early practices in horticulture include various tools and methods of land management, with different methods and plant types used for different uses. Methods, tools and plants grown have always depended on the culture and climate.[citation needed]
Many traditional horticultural practices are known, such as the Indigenous peoples of pre-colonized North America using biochar to enhance soil productivity by smoldering plant waste[11] – European settlers called this soil Terra Preta de Indio.[12] In North America, Indigenous people grew maize, squash, and sunflower, among other crops. Mesoamerican cultures focused on cultivating crops on a small scale, such as the milpa or maize field, around their dwellings or in specialized plots which were visited occasionally during migrations from one area to the next.[13] In Central America, the Maya involved augmentation of the forest with useful trees such as papaya, avocado, cacao, ceiba and sapodilla. In the fields, multiple crops such as beans, squash, pumpkins and chili peppers were grown. The first horticulturists in many cultures were mainly or exclusively women.[14]
In addition to plants' medicinal and nutritional value, plants have also been grown for their beauty, to impress and to demonstrate power, knowledge, status and even wealth of those in control of the cultivated plant material. This symbolic power that plants hold has existed even before the beginnings of their cultivation.[15]
There is evidence that various gardens maintained by the Aztecs were sacred, as they grew plants that held religious value. Plants were grown for their metaphorical relation to gods and goddesses.[10] Flowers held symbolic power in religious rites, as they were offered to the gods and given in ceremonies to leaders to demonstrate their connection to the gods.[10]
Plant propagation in horticulture is the process by which the number of individual plants is increased. Propagation involves both sexual and asexual methods.[16] Sexual propagation uses seeds, while asexual propagation involves the division of plants, separation of tubers, corms, and bulbs using techniques such as cutting, layering, grafting.[17]
When selecting plants to cultivate, a horticulturist may consider aspects based on the plant's intended use, including plant morphology, rarity, and utility.[18] When selecting plants for the landscape, observations of the location must be made first. Soil type, temperature, climate, light, moisture, and pre-existing plants are considered when selecting plant material for the location. Plant selection may be for annual displays, or they may be for more permanent plantings. Characteristics of the plant – such as mature height and size, colour, growth habit, ornamental value, flowering time and invasive potential – finalize the plant selection process.[citation needed]
Environmental factors affecting plant development include temperature, light, water, soil pH, nutrient availability, weather, humidity, elevation, terrain, and micro-climate.[1] In horticulture, these environmental variables may be avoided, controlled or manipulated in an indoor growing environment.
Plants require specific temperatures to grow and develop properly. Temperature can be controlled through a variety of methods. Covering plants with plastic in the form of cones called hot caps, or tunnels, can help to manipulate the surrounding temperature. Mulching is also an effective method to protect outdoor plants from frost during the winter. Inside, other frost prevention methods include wind machines, heaters, and sprinklers.[19]
Plants have evolved to require different amounts of light and lengths of daytime; their growth and development are determined by the amount of light they receive. Control of this may be achieved artificially with fluorescent lights in an indoor setting. Manipulating the amount of light also controls flowering. Lengthening the day encourages the flowering of long-day plants and discourages the flowering of short-day plants.[19]
Water management methods involve employing irrigation and drainage systems and controlling soil moisture to the needs of the species. Irrigation methods include surface irrigation, sprinkler irrigation, sub-irrigation, and trickle irrigation. Watering volume, pressure, and frequency are changed to optimize the growing environment. On a small scale, watering can be done manually.[19]
The choice of growing media and components to the media help support plant life. Within a greenhouse environment, growers may choose to grow their plants in an aquaponic system where no soil is used. Growers within a greenhouse setting will often opt for a soilless mix which does not include any actual components of naturally occurring soil. These mixes are generally very available within the industry and offer advantages such as water absorption and sterility.[citation needed]
Soil management methods are broad but include the applying fertilizers, planned crop rotation to prevent the soil degradation seen in monocultures, and soil analysis.[19]
Abiotic factors such as weather, light and temperature are all things that can be manipulated with enclosed environments such as cold frames, greenhouses, conservatories, poly houses and shade houses. Materials used in constructing these buildings are chosen based on the climate, purpose and budget.[citation needed]
Cold frames provide an enclosed environment; they are built close to the ground and with a top made of glass or plastic. The glass or plastic allows sunlight into the frame during the day and prevents heat loss that would have been lost as long-wave radiation at night. This allows plants to begin growing before the growing season starts. Greenhouses and conservatories are similar in function but are larger and heated with an external energy source. They can be built out of glass but are now primarily made from plastic sheets. More expensive and modern greenhouses can include temperature control through shade and light control or air-conditioning and automatic watering. Shade houses provide shading to limit water loss by evapotranspiration.[19]
Commercial horticulture is required to support a rapidly growing population with demands for its products.[20] Due to global climate change, extremes in temperatures, strength of precipitation events, flood frequency, and drought length and frequency are increasing. Together with other abiotic stressors such as salinity, heavy metal toxicity, UV damage, and air pollution, stressful environments are created for crop production. This is extrapolated as evapotranspiration is increased, soils are degraded of nutrients, and oxygen levels are depleted, resulting in up to a 70% loss in crop yield.[citation needed]
Living organisms such as bacteria, viruses, fungi, parasites, insects, weeds and native plants are sources of biotic stresses and can deprive the host of nutrients.[21] Plants respond to these stresses using defence mechanisms such as morphological and structural barriers, chemical compounds, proteins, enzymes and hormones.[22] The impact of biotic stresses can be prevented using practices such as incorporate tilling, spraying or Integrated Pest Management (IPM).[23]
Care is required to reduce damages and losses to horticultural crops during harvest.[24] Compression forces occur during harvesting, and horticultural goods can be hit in a series of impacts during transport and packhouse operations. Different techniques are used to minimize mechanical injuries and wounding to plants such as:[25]
Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) has recently gained recognition as a highly efficient, simplified, precise, and low-cost method of altering the genomes of species.[26] Since 2013, CRISPR has been used to enhance a variety of species of grains, fruits, and vegetables. Crops are modified to increase their resistance to biotic and abiotic stressors such as parasites, disease, and drought as well as increase yield, nutrition, and flavour.[27] Additionally, CRISPR has been used to edit undesirable traits, for example, reducing the browning and production of toxic and bitter substances of potatoes. CRISPR has also been employed to solve issues of low pollination rates and low fruit yield common in greenhouses. As compared to genetically modified organisms (GMO), CRISPR does not add any alien DNA to the plant's genes.[28]
Various organizations worldwide focus on promoting and encouraging research and education in all branches of horticultural science; such organizations include the International Society for Horticultural Science[4] and the American Society of Horticultural Science.[5]
In the United Kingdom, there are two main horticulture societies.[citation needed] The Ancient Society of York Florists is the oldest horticultural society in the world and was founded in 1768; this organization continues to host four horticultural shows annually in York, England.[29] Additionally, The Royal Horticultural Society, established in 1804, is a charity in United Kingdom that leads on the encouragement and improvement of the science, art, and practice of horticulture in all its branches.[30] The organization shares the knowledge of horticulture through its community, learning programs, and world-class gardens and shows.[citation needed]
The Chartered Institute of Horticulture (CIH) is the Chartered professional body for horticulturists and horticultural scientists representing all sectors of the horticultural industry across Great Britain, Ireland and overseas. While horticulture is an unregulated profession in the United Kingdom, the title of Chartered Horticulturalist is regulated by the CIH.[31] The Australian Institute of Horticulture and Australian Society of Horticultural Science were established in 1990 as a professional society to promote and enhance Australian horticultural science and industry.[32] Finally, the New Zealand Horticulture Institute is another known horticultural organization.[33]
In India, the Horticultural Society of India (now the Indian Academy of Horticultural Sciences) is the oldest society; it was established in 1941 at Lyallpur, Punjab (now in Pakistan) but was later shifted to Delhi in 1949.[34] The other notable organization in operation since 2005 is the Society for Promotion of Horticulture based at Bengaluru.[35] Both these societies publish scholarly journals – Indian Journal of Horticulture and Journal of Horticultural Sciences for the advancement of horticultural sciences.[citation needed] Horticulture in the Indian state of Kerala is led by Kerala State Horticulture Mission.[citation needed]
The National Junior Horticultural Association (NJHA) was established in 1934 and was the first organization in the world dedicated solely to youth and horticulture. NJHA programs are designed to help young people obtain a basic understanding of horticulture and develop horticultural skills.[36]
The Global Horticulture Initiative (GlobalHort) fosters partnerships and collective action among different stakeholders in horticulture. This organization focuses on horticulture for development (H4D), which involves using horticulture to reduce poverty and improve nutrition worldwide. GlobalHort is organized in a consortium of national and international organizations which collaborate in research, training, and technology-generating activities designed to meet mutually agreed-upon objectives. GlobalHort is a non-profit organization registered in Belgium.[37]
Pruning is a horticultural, arboricultural, and silvicultural practice involving the selective removal of certain parts of a plant, such as branches, buds, or roots.
The practice entails the targeted removal of diseased, damaged, dead, non-productive, structurally unsound, or otherwise unwanted plant material from crop and landscape plants. In general, the smaller the branch that is cut, the easier it is for a woody plant to compartmentalize the wound and thus limit the potential for pathogen intrusion and decay. It is therefore preferable to make any necessary formative structural pruning cuts to young plants, rather than removing large, poorly placed branches from mature plants.
Woody plants may undergo a process referred to as "self-pruning", where they will drop twigs or branches which are no longer producing more energy than they require. It is theorized that this process can also occur in response to lack of water, in order to reduce the surface area where water can be lost.[1] This natural shedding of branches is called cladoptosis.
Specialized pruning practices may be applied to certain plants, such as roses, fruit trees, and grapevines. Different pruning techniques may be used on herbaceous plants than those used on perennial woody plants.
Reasons to prune plants include deadwood removal, shaping (by controlling or redirecting growth), improving or sustaining health, reducing risk from falling branches, preparing nursery specimens for transplanting, and both harvesting and increasing the yield or quality of flowers and fruits.
Branch wood is an individual stem that grows off of another stem.
Trunk wood is the main stem of a tree which individual stems grow out of.
This refers to the area below the union of where branch wood attaches with the trunk/stem wood. This can often appear raised.
This refers to the junction between branch wood and trunk/stem wood. It usually looks raised. [2]
Pruning in an urban setting is crucial due to the tree being in drastically different conditions than where it naturally grows.[3]
Arborists, orchardists, and gardeners use various garden tools and tree cutting tools designed for the purpose, such as secateurs, loppers, handsaws, or chainsaws.[4] Additionally in forestry, pole pruners (averruncators in British English) and pole saws are commonly used, and these are often attached to poles that reach up to 5–6 m (16–20 ft). This is a more efficient and safer way of pruning than with ladders. These bush saws on polls have also been motorized as chainsaws which is even more efficient. Older technology used Billhooks, Kaiser blades, and pruning knives. Although still used in some coppicing, they are not used so much in commercial forestry due to the difficulty of cutting flush with the stem. Flush cuts happen when a pruner cuts into the cambium layer of the main trunk, which can happen when a pruner is not precise with pruning cuts, and removes a portion of the branch collar, which can put the tree at risk of entry cords from forest pathogens.
Although there are several different types of pruning, they can be simplified into two categories. One of which is cutting the branch back to a specific and intermediate point, called a "reduction cut", and the other of which is completely removing a branch back to the union where the branch connects which the main trunk, called "removal cut".[5]
A "reduction cut" is when one removes a portion of a growing stem down to a set of desirable buds or side-branching stems. This is commonly performed in well trained plants for a variety of reasons, for example to stimulate growth of flowers, fruit or branches, as a preventive measure to wind and snow damage on long stems and branches, and finally to encourage growth of the stems in a desirable direction.
In orchards, fruit trees are often lopped to encourage regrowth and to maintain a smaller tree for ease of picking fruit. The pruning regime in orchards is more planned, and the productivity of each tree is an important factor.
Branches die off for a number of reasons including sunlight deficiency, pest and disease damage, and root structure damage. A dead branch will at some point decay back to the parent stem and fall off. This is normally a slow process but can be hastened by high winds or extreme temperatures. The main reason deadwooding is performed is safety. Situations that usually demand removal of deadwood include trees that overhang public roads, houses, public areas, power lines, telephone cables and gardens. Trees located in wooded areas are usually assessed as lower risk but assessments consider the number of visitors. Trees adjacent to footpaths and access roads are often considered for deadwood removal.[8]
Another reason for deadwooding is amenity value, i.e. a tree with a large amount of deadwood throughout the crown will look more aesthetically pleasing with the deadwood removed. The physical practice of deadwooding can be carried out most of the year though should be avoided when the tree is coming into leaf. The deadwooding process speeds up the tree's natural abscission process. It also reduces unwanted weight and wind resistance and can help overall balance.
Preventative and structural pruning can be done to mitigate several issues young trees may have in the future. The structural pruning can reduce tree stress, increase the lifespan of trees, and promotes resistance to damage due to natural weather events. Attributes of trees with good structure include excurrent growth by having a single dominant leader, branch unions without included bark, and a balanced canopy. Structural pruning does this by developing or maintaining a dominant leader, identify the lowest branches in the canopy, prevent branches below the permanent canopy from growing too large, keeping all branches less than one half the trunk diameter, space main branches along one dominant trunk, and suppress growth on branches with included bark. [9]
Subordination pruning is done on limbs that will exceed 50% percent of the stem diameter. A reduction cut may be performed while still allowing about 50% of the branch. This is done to help maintain form and deter the formation of co-dominant leaders. Temporary branches may be too large for a removal cut so subordination pruning should be done to slowly reduce a limb by 50% each year to allow the tree to properly heal from the cut. As a tree becomes larger the slower it grows. Reducing the larger limbs for eventual removal will allow for the tree to promote new growth rather than using energy in encouraging unwanted limbs to continue to grow. Removing a large branch increases the likelihood of the cut to not heal properly which also may attract insects, diseases and fungus. [9][10]
Crown thinning is the removal of live healthy branches which increases light penetration, air circulation and reduces wind resistance which reduces risks from damage and the possibility of pest infestation. [11]
Crown raising involves the removal of the lower branches to a given height. The height is achieved by the removal of whole branches or removing the parts of branches which extend below the desired height. The branches are normally not lifted to more than one third of the tree's total height.
Crown lifting is done for access; these being pedestrian, vehicle or space for buildings and street furniture. Lifting the crown will allow traffic and pedestrians to pass underneath safely. This pruning technique is usually used in the urban environment as it is for public safety and aesthetics rather than tree form and timber value.
Crown lifting introduces light to the lower part of the trunk; this, in some species can encourage epicormic growth from dormant buds. To reduce this sometimes smaller branches are left on the lower part of the trunk. Excessive removal of the lower branches can displace the canopy weight, this will make the tree top heavy, therefore adding stress to the tree. When a branch is removed from the trunk, it creates a large wound. This wound is susceptible to disease and decay, and could lead to reduced trunk stability. Therefore, much time and consideration must be taken when choosing the height the crown is to be lifted to.
This would be an inappropriate operation if the tree species’ form was of a shrubby nature. This would therefore remove most of the foliage and would also largely unbalance the tree. This procedure should not be carried out if the tree is in decline, poor health or dead, dying or dangerous (DDD) as the operation will remove some of the photosynthetic area the tree uses. This will increase the decline rate of the tree and could lead to death.
If the tree is of great importance to an area or town, (i.e. veteran or ancient) then an alternative solution to crown lifting would be to move the target or object so it is not in range. For example, diverting a footpath around a tree's drip line so the crown lift is not needed. Another solution would be to prop up or cable-brace the low hanging branch. This is a non-invasive solution which in some situations may be more economical and environmentally friendly. [12]
Selectively pruning a window of view in a tree.
Reducing the height and or spread of a tree by selectively cutting back to smaller branches and in fruit trees for increasing of light interception and enhancing fruit quality.
A regular form of pruning where certain deciduous species are pruned back to pollard heads every year in the dormant period. This practice is usually commenced on juvenile trees so they can adapt to the harshness of the practice. This practice can be used for tree shaping but is also used in specific species which young branches can be sold for floral arrangements.
Deadheading is the act of removing spent flowers or flowerheads for aesthetics, to prolong bloom for up to several weeks or promote rebloom, or to prevent seeding.
In general, pruning deadwood and small branches can be done at any time of year. Depending on the species, many temperate plants can be pruned either during dormancy in winter, or, for species where winter frost can harm a recently pruned plant, after flowering is completed. In the temperate areas of the northern hemisphere autumn pruning should be avoided, as the spores of disease and decay fungi are abundant at this time of year.
Some woody plants tend to bleed profusely from cuts, such as mesquite and maple. Some callus over slowly, such as magnolia. In this case, they are better pruned during active growth when they can more readily heal. Woody plants that flower early in the season, on spurs that form on wood that has matured the year before, such as apples, should be pruned right after flowering as later pruning will sacrifice flowers the following season. Forsythia, azaleas and lilacs all fall into this category.
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:
This tree service quickly came out and gave me an estimate. Showed up as promised, completed the work in a timely manner and cleaned up afterwards. I got three estimates and this one was reasonably priced. I will definitely be a repeat customer.
This gentleman is legit. I can tell you that my husband and I hired him in April 20 and he sent us an email with a certificate showing us that his company was insured and he was very prompt. He came out and took a look at the property and the trees and gave us advice and a free quote. We quickly decided on the spot to hire him . We decided on a price and a time and a date was set . He returned my questions via email and text message right away. He showed up very early. His men did a fantastic job, cutting down two very seriously high trees that were looming over the roof of our house and have had us worried for so many years. I highly recommend this gentleman and his team. They are very conscientious and professional, and we will be using their services again.
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.
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.
