Review of models of food resources evaluation of the forests of central Russia

The article analyzes the most favourable conditions for the growth and fruit bearing of berries and mushrooms; studies yield indices of food resources; examines Russian and foreign yield capacity models of forest food resources. It is proposed to use illumination at the level of ground cover, which is an informative parameter, for modelling the dynamics of yield capacity of food resources. Illumination estimation will help us to more accurately assess the yield of food resources not only in single-storeyed stands with understorey trees and undergrowth, but also in multi-storeyed stands.
