Conservation stocks of mountain pine (stocks)

The data set contains the area-based genetic conservation stocks of the mountain pine. Genetic conservation stocks are selected forest areas or individual trees that are important for the conservation of forest gene resources. The species of tree, the number of individual trees, the date of the data collection and the year of authorisation for the conservation of genes shall be indicated for each area or individual object. The basis for digital data collection is the collection documents of the specialist unit for the documentation of gene conservation objects.
