Quantitative ecological and genetic studies in the pine forests of North Eurasia based on the example of Pinus sylvestris L. have allowed the constructive population genetic and ecological principles and parameters for selection, assessment, and classification of forest genetic reserves (FGRs) to be grounded. The genetic parameters of FGR populations (the minimum area, disturbance by cutting, and the influx of foreign pollen) are regarded as undoubtedly top-priority factors, as tree-stand vitality and germination capacity are regarded as key ecological factors. We propose to give a general estimate for the class of FGR quality using an integral ranking scale for five genetic and ecological parameters based on the class of the FGR area. This class increases by 0.5 with an increase (deterioration) by one class of any other considered parameter. This system provides the possibility to create a unified system for ecologically and genetically grounded selection of FGRs and assessment of their classes.
