Forestry of Lisino as the unique testing area for the soil and ecologic monitoring

Forestry of Lisino is the perspective area for the organization and conduction of soil and ecologic monitoring. It is characterized by ecosystems, typical for the North-West, which are least altered by anthropogenic impact. Also it is characterized by the availability of long-term investigation materials of soils and soil cover, and the availability of soil monoliths collected at different years. A. A. Rode made a substantial contribution in the investigation of soils and soil cover of forestry of Lisino. The changes of typomorphic characteristics were determined and the analysis of taxonomic structure of microbiome was conducted for the soddy-podzolic soil developed on driftless clay loam. On the basis of comparative analysis of actual samples from the soddy-podzolic soils and the samples from soil monoliths, it was set that the significant pH decrease occurred during the 75 years, and the degree of base saturation also decreased significantly. The monitoring polygons are lain along the II International Soil Scientists Congress route held in 1930. The separation of seven objects of soil and ecologic monitoring is substantiated, as they characterize all ecosystems typical for Lisin forestry. The soils of the four objects of monitoring are included in the Red Book of soils of Leningrad oblast: the soddy-podzolic soil developed on the moraine loams - “the Pit of Rode”, the soddy elluvial metamorphic developed on varved clays - “Kostenki”, the peat humic gleyzem oxidative gley - “Sulanda” and alluvial gray humic soil - “Lustovka”.
