Long-term dynamics of plant communities after biological remediation of oil-contaminated soils in far north
Abstract We studied the long-term dynamics of plant communities after bio and phytoremediation of oil-polluted soils. Nine plots located in European Northeast and treated using various bioremediation methods were monitored from 2002 to 2014. Geobotanical descriptions (relevés) of each plot were perf...
