Assessment of environmental situation and problems of biodiversity conservationin the reserve Makarovskiy (Sakhalin island)

Wildlife reserve "Makarovskiy" is a protected natural territory intended for preservation of rare and vanishing species of plants and animals. The vegetative cover of the reserve includes dark coniferous forest, mountain birch forests, jungles of cedar elfin wood, poplar-birch-willows forests of valleys, the alpine tundra belt. They represent unique vegetative communities that are necessary to be saved. Decoding of space images of "Makarovsky" has allowed revealing considerable diversity of the spectral brightness reflecting the condition of vegetation on its territory. The basic part of investigated objects has been allocated during the analysis of pictures in red and infrared zones; quantization pictures in these zones have been combined and received parities of optical density D red/D infrared for each contour. According to brightness in the red and the infrared zones territories with various vegetative formations were distinctly distinguished: dark coniferous forest, mountain birch forests and others. In images of territories with mountain taiga forest vegetation and mountain birch forests, pictures with various optical density reflecting distinctions indensity of vegetation depending on geoecological conditions are allocated. It is recommended to preserve the status of wildlife reserve"Makarovskiy" on Sakhalin island, and also to take measures to increase the efficiency of wildlife management of its territory for savingbiodiversity.
