Forest Inventory - accounting of the forest, its material assessment: determining the age, height, and diameter of growing trees, timber stock, annual growth, forest plantations; qualitative assessment of the forest.
Forestry Survey - a complex of technical actions aimed at identifying, accounting for, and evaluating quantitative (stock) and qualitative (merchantability) characteristics of forest resources.
Why Forest Inventory is Needed
Forest inventory using deciphering methods is conducted to identify, account for, and assess quantitative and qualitative characteristics of forest resources (calculating the height and age of forest plantations, average diameter, average height, relative density, stand rating, stock per 1 ha).
Inventory is carried out before logging forest plantations for logging and sanitary purposes, as well as complete clear-cuttings for infrastructure projects, with the following result: re-measurement of the quantity and quality of the forest in a particular area, namely:
- determining the dimensions (height, diameter), age, species, number of growing trees, timber stock, and its annual growth for subsequent logging purposes.
Differences in Conducting Forest Inventory in Russia and in the European Union / Canada / USA:
The key task is to determine the volume of merchantable timber per hectare and per delineated canopy captured in the imagery, with known age and species composition. Other characteristics of the forest, as well as accounting for forestry activities and numerical estimation methods (sampling "strip" and others), are not considered. This is why it is easier to apply new DZZ technologies.
Moreover, in the USA / Canada / European Union, auditors accept data obtained by DZZ methods as the evaluation of merchantable timber stocks (forest resource assessment) with confirmation from reference areas.
Composition of Works for Assessing the Volume of Merchantable Timber:
counting the canopies per hectare and delineated areas.
determining the type of canopy closure.
determining (clarifying) the species composition.
calculating the timber volume using an approximate formula of canopy ratio for a given age and stem diameter for a given forest type.
Objectives of Forest Inventory:
- Obtaining timely information about the condition of forest plantations;
- Identifying and studying the patterns of growth, structure, and merchantable timber composition.
Tasks of Forest Inventory:
- Measurement and accounting of the stock of individual trees, stands, and forest plantations;
- Accounting for the areas, volumes, and stock of the forest with the preparation of planimetric and cartographic materials;
- Providing rare and valuable information about the forests that is relevant and up-to-date.

Objectives of Remote Sensing-based Forest Inventory (Satellite, Aerial Photography, UAV):
The aim of forest inventory is to study the forest inventory indicators, observation units, and accounting based on modern information technologies.
Through inventory activities, tasks are solved to form an information base of the forest fund. This allows for the assessment of the state and dynamics of forest resources, maintain tables of stock, species, age, composition of existing forest plantations, and tree heights.
Main tasks of forest inventory:
- Improvement of forest inventory methods, ensuring complete identification and reliable assessment of all resources and functions of forest plantations, and increasing the profitability of forestry on this basis;
- Providing normative accuracy in determining forest fund indicators during forest inventory work on forest management units and ensuring the promptness of obtaining this information;
- Creation and maintenance of a centralized database on the forest fund of the forest management unit, combining cartographic and inventory information (GIS technologies);
Forest inventory is conducted as a stage of continuous forest management, as planned work, or upon request by individual companies leasing forest areas for logging purposes and in some other cases.
Advantages of Using Remote Sensing Data:
- Obtaining up-to-date and reliable data for forest management, improving the quality of work while reducing the time of their execution;
- Exploring hard-to-reach forest areas;
- Possibility of year-round work;
- Reducing the time required for forest inventory;
- Best balance of cost and quality of results obtained.
