REVIEW OF MODELS OF ESTIMATION OF FOOD RESOURCES OF FORESTS OF THE CENTRAL PART OF RUSSIA

The article analyzes the conditions most favorable for the growth and fruiting of berries and mushrooms. The indicators of productivity of food resources are studied. The Russian and foreign models of forest food resource productivity are considered. It is proposed to use an informative parameter such as illumination at ground cover level to model the dynamics of food resource productivity. Having calculated it, it is possible to more accurately estimate the yield of food resources not only in single-tier, having undergrowth and undergrowth, but also in multi-tiered stands.
