DYNAMICS OF PINE FOREST STRUCTURE ON A PEAT BOG REVEALS HALF-CENTENNIAL FOREST DECAY AND ONGOING SUCCESSION (DARWIN BIOSPHERE RESERVE, NW RUSSIA)
Abstract
Bogs of Darwin Biosphere reserve (southern NW Russia) represent sustain ecosystem balance on an outstandingly large scale. Dynamics of the bog metabolism and structure should be estimated both under the influence of the Rybinsk reservoir and beyond it (in terms of natural evolution), although these cannot always be distinguished clearly. Forested bog areas are most sensible ecosystems to trace decadal or centennial dynamics of the landcover. Longstanding observations of the geobotanical and forest structure have been continuously performed in Darwin Nature Biosphere reserve from 1947 to 2012 within a series of the model grounds. Changes of parameters of sphagnous pinewood through 65 years are overviewed, based on the on-site censuses and, partially, remote sensing data. During the first decades of observations (1947-1991) the accounted forest stand gained maturity, and ultimately tree died off numerously. Pinewood shrinkage was noticed in 1990-s, due to the reached tree age limits (in bog conditions), and the durative drought to have affected those years. At present mature and undergrowth pine stand covers almost 1.7 times less of the surrounding 500-area around the model ground, than 40-50 years ago, mainly due to the tree dying off in 1990-2000. A 20-year forest regrowth brings repopulation of pine on the site, which gradually spreads over the bog around the model ground. The assessed changes of qualitative and quantitative properties of the microlandscape enable to trace ecosystem function transformation on the local level, i.e., enhancement of peat soil humidity, hygrophytic vegetation appearance, and reformation of habitats suitable for bog-nesting birds, as the pine forest decayed.
