The inventory of the production fund aims to determine its size, structure and growth, starting with the determination of the dendrometric characteristics of each component tree. This inventory is done both for the purpose of regulating the production and protection process and for controlling the production fund and its evolution. The inventory methodology is based on the application of the methods of mathematical statistics and especially on the application of selective methods, as well as by scientifically based dendrometric estimations. In the case of these inventories, will be determined: the average diameter, the average height, the specific composition, the number of trees per hectare (density), the density index, the current growth by species, classes of diameters and quality classes, the volume of the trees. The trees that have reached the age of exploitability must be inventoried to determine the volume. Stands with a consistency of more than 0.4 and a surface area greater than 4.0 ha will be inventoried by the 12.62 m radius of circle and a 500 m2 area, uniformly located in the entire layout, and those with consistencies of less than 0.4 will be fully compiled by the forest district, as they will enter the first-ever decennial plan. The only condition is the existence of a digital layout map, which can be obtained from the parcel and parcel construction work with the redevelopment works in the Stereographic 70 projection, where the position of each circle can easily be materialized with Qgis software.
