On the issue of preserving phytodiversity in the territories of agroecosystems

The biodiversity of natural habitats is undergoing significant changes due to the anthropogenic transformation of flora. At the same time, a significant share of plant diversity is concentrated in plant communities on secondary habitats, including agricultural lands, where a number of ecosystems are supported on the territory of Russia. The phyto-diversity of the agroecosystem consists of plants concentrated both on anthropogenic habitats (segetal and ruderal) and on island areas of undisturbed habitats, making up the weed flora of the agroecosystem. Weed flora, being a subdivision of natural flora, is characterized by stability. Therefore, in agroecosystems, it is possible not only to regularly study the phyto-diversity, but also to develop issues of its conservation. The potential for the practical use of the phyto-diversity of agroecosystems includes plant species related to wild medicinal, food and technical raw materials, as well as honey plants. The presence of species that are wild relatives of cultivated plants, the use of which in breeding contributes to the improvement of economically valuable qualities of cultivated plants, increases the importance of preserving these species in agroecosystems. Organic farming, organized with the preservation of the natural appearance of the landscape and the structure of plant communities with their genetic diversity, contributes to the preservation of phyto-diversity. It is required to create a methodology for monitoring biodiversity in agricultural landscapes with the development of comparable methods of data collection in different ecotopes and the organization of information storage in a common database with remote access.
