Creation of GIS-maps for information structuring and an integrated approach in the use of resource species of forest ecosystems

Abstract

Populations of species living at the edge of their range need long-term and constant monitoring to analyze the number and condition of individuals of the species. When populations fall out of natural phytocenoses in conditions of regulated nature management, it is possible to restore these cenopopulations by repopulation. For optimization of work on structuring of data on populations, a GIS-map of medicinal plants was created. A full set of studies has been carried out for Bupleurum aureum populations, which are experiencing significant anthropogenic pressure near the western border of its range. The species has practically disappeared from the broad-leaved forests of the Predvolga region. The created GIS-map contains information with precise georeferencing of the identified cenopopulations in relation to landscape and soil type. Another block of the GIS-map database contains information on productivity and genetic polymorphism of cenopopulations, which should be taken into account when restoring lost populations.The conducted studies have shown that the share of generative plants of B. aureum in the population decreases when the light intensity decreases in the forest. In this case, individuals preserved in meadows adjacent to the forest are of great importance. It can be assumed that forest edge communities are important key sites for the conservation of forest biodiversity.
