Monitoring of the pine forests status in the Tolyatti urban area in 2002-2006 gg.
It was found while monitoring the 6 permanent sample plots in the Tolyatti urban area within the observation period from 2002 to 2006 that the process of degradation of old-growth stands is getting faster at the current level of anthropogenic impact. The indicators that objectively reflect the processes of plants degradation were developed when comparing data before and after logging on monitoring sites: the relative rate of the change in the sanitary state category of trees surviving to 2006 and the relative rate of the change in the sanitary state category by 2006 for the trees classified as the first category in 2002.
