Descripción
Since ancient times, wild berries in the North have been considered the most valuable food raw material along with the main food products. The most important food berry resources in the European North of Russia include cranberries (Vaccinium oxycoccos L.), lingonberries (Vaccinium vitis-idaea L.), blueberries (Vaccinium myrtillus L.), cloudberries (Rubus chamaemorus L.).
The concept of the carried out research is to ensure the sustainable use of non-wood forest resources to improve the health, food, income, employment, and well-being of the population (SDGs 2, 12, 15). Nowadays the knowledge on the forest berry yielding capacity and related forecasts is in demand with businesses dealing with the use of non-wood raw products, which are of high spatio-temporal variability. Based on the analysis of the available stock materials, general methodological approaches were developed for determining the potential yield capacity by species and combinations of species of berry raw materials in the form of an average annual merchantable stock in kilograms of raw materials per unit area (hectare) for each
unit of managed forests (lesnichestvo). It can be used in the planning of forest use for harvesting non-wood forest products. Analysis of spatial information showed that in terms of food berry resources the most productive are the forests of the southern part of the European North of Russia, located in the subzones of the middle and southern taiga. It was revealed that the ecological and biological characteristics of the studied berry species largely determined the localization of areas characterized by their high operational stocks. The main factors, determining the spatial localization of the operational stocks of lingonberry and blueberry, are the landscape features of the territory as well as the level of anthropogenic impact that provides for a high
proportion of felling sites of various ages in the lingonberry and blueberry groups of forest types.
