Composition of plant communities in natural and technogenically disturbed ecotopes on watersheds of the Yamal Peninsula: Floristic diversity

Specific features in the overgrowing of technogenically disturbed areas with completely destroyed soil and plant cover (a sand pit, a causeway, and an off-road vehicle trail) have been studied in the environs of the Bovanenkovo Oil-Gas Condensate Field. It is shown that the vegetation of natural ecotopes and ecotopes disturbed approximately 20 years ago is characterized by a relatively high similarity in the composition of vascular plants. The total species composition of plant communities (including mosses and lichens) and their structure show a considerable loss of floristic and phytocenotic diversity.
