What is dendrological inventory?
Dendrological inventory, also known as green inventory, is work aimed at creating an accurate quantitative and qualitative inventory of trees and shrubs in a given area. It allows for the gathering of comprehensive data on the vegetation present there. The entire inventory process consists of fieldwork, during which specialists determine the location of vegetation and carry out necessary measurements.
During the green inventory, valorization is also carried out, which involves assessing the current health and environmental status of the tree population. Trees are usually assessed visually, using the Visual Tree Assessment (VTA) method. It is based on visible characteristics that may affect the weakening and stability loss of the tree and increase the risk of damage caused by them. Valorization takes into account the tree base, trunk, crown, and the presence of pathogens and pests. This allows experts to assess the risk posed by leaving trees for the planned investment.
Process of dendrological inventory
Green inventory is the process of gathering information about plants growing in a particular location, including both trees and shrubs as well as grasses, bushes, flowers, and other plants. Depending on the objectives, this process may consist of various elements, but in general, green inventory includes:
- Species identification of trees – recognizing plant species, determining their age, condition, size, and tree location.
- Plant characteristics – a detailed description of the physical and biological parameters of plants, such as trunk diameter, tree height, crown spread, condition, etc.
- Determination of tree health status – assessing the condition of plants, including detecting diseases, pests, mechanical damage, and other threats.
- Estimation of ecological and landscape value of plants – conducting an inventory involves assessing the impact of plants on the environment and landscape, determining their natural and aesthetic value.
- Planning vegetation-related actions – based on the collected data, a plan for vegetation-related actions can be developed, such as maintenance procedures, pruning, tree removal, planting new plants.
What should dendrological inventory include?
Dendrological inventory utilizes dendrological books, maps, and various tools: altimeters, diameter tapes, measuring tapes. All of this serves to prepare comprehensive documentation, consisting of descriptive and graphical parts. The descriptive part of the inventory contains a table containing a list of trees along with their detailed description. The summary of the green inventory typically consists of:
- Polish and Latin names of trees and shrubs,
- Trunk diameter at a height of 130 cm,
- Trunk circumference at a height of 5 cm,
- Trunk circumference at a height of 130 cm,
- Tree height,
- Crown spread of trees,
- Tree age,
- Height and surface area of the shrub (in m2),
- Description of health condition,
- Risk assessment.
Additionally, tree inventory should also include a description of the terrain, methodology of conducted works, a brief characterization of the vegetation, information about the purpose and scope of the conducted works. The description can also be enriched with indications regarding green maintenance and a list of trees and shrubs qualified for removal.
The graphical part of the inventory consists of a map of the inventoried area, on which trees and shrubs to be retained, removed, or transplanted are marked. The map must include planned building objects, which allows identifying conflicting trees and shrubs. Green inventory is often supplemented with photographic documentation depicting the condition of trees. It also includes a forest management plan and a proposal for replacement planting to be carried out after removal.
Why is dendrological inventory important?
Forest inventory helps to properly plan the spatial layout of a new garden or green area. It is useful in organizing and designing a given area. It also has significant importance from the perspective of nature conservation. What are its exact applications and in which areas can it prove to be crucial?
Investments and constructions
Green inventory facilitates the estimation of the cost of work during construction or establishment of a garden or green area. It allows identifying trees conflicting with construction or posing potential risks to people and buildings, as well as those characterized by valuable natural features. Thus, it is possible to plan construction to protect and preserve them. Therefore, it is worth conducting inventory not only as part of preparations for major investments but also for work in one’s own garden.
Nature conservation and biodiversity preservation
The knowledge obtained during dendrological inventory may concern, for example, the occurrence of trees in a given location that are natural monuments or legally protected trees. Thanks to this, decisions can be made regarding the prohibition of felling, transplanting trees to a designated location, or carrying out replacement plantings in a specified area.
In the case of protected trees, the results of dendrological inventory often influence the necessity of changing the location of surface and linear investments.
Green maintenance
Tree inventory for removal is also helpful in green maintenance. Thanks to it, the condition of the forest can be assessed, potential risks can be detected, it can be determined which trees require special protective measures, and their maintenance can be planned. Based on it, one can apply for the designation of trees as natural monuments. It also has educational value – thanks to it, one can get to know their surroundings and appreciate the values of the local nature.
When should dendrological inventory be conducted and who can perform it?
Depending on the size of the area and the number of trees and shrubs to be inventoried, forest inventory can take from several days to several weeks. Inventory work can be conducted throughout the year, but performing it during the growing season helps gather the most accurate data on the phytosanitary condition of the trees. The inventory remains valid for six months from the date of its preparation.
The inventory should be conducted by a specialist. Individuals who can conduct dendrological inventory should have relevant knowledge and experience in landscape architecture, forestry, or dendrology. It is worth relying on a professional to ensure that the service is carried out thoroughly.
