Forests of Tuva concern to southern boreal forests of Siberia. Ones are possess specificity because of complexity and sharp exposition contrast of ecological conditions and steepness of mountain relief. Features interlacing of forest and steppe elements landscape and absence are cause of transitive belts in places of contacts high sensitivity of vegetation of forests one’s ridge. Therefore researches are represented big interest of mountain forests for estimating of role in global changes of climate and ecological cycles these forests.

Through range Tannu-Ola the range-profile was incorporated for ground researches on southern part of region in subboreal areas. Through range Tannu-Ola the range-profile was incorporated for ground researches on southern part of region in subboreal areas. On plots of profile are lead field descriptions, conditions of forest and sapling are analyzed and given consideration of cedar sapling as indicator of climate. It should be observed that good cedar sapling grows on the top and bottom border of a forest on northern slope of ridge extending for limits of cedar files. Process distribution of cedar sapling on the top border of forest shows about warming climate. And on the bottom border shows about increase in humidity of soil. It shows about mitigation of a climate and there is an expansion of an area of cedar on mountains.

Field descriptions, forest mensuration data and map-scheme forest fund, and data with classification of altitude-zone complexes with forest-grow conditions are integrated into local database of range Western Tannu-Ola. Maps transfered in digital format by means of ArcView and MapInfo included in database: topology 1:200000, landscape 1:4000000, soil 1:1000000, vegetation 1:5000000, forest 1:5000, hydrology 1:200000 scales and satellite images dates NOAA, Modis.

The created local information system range Western Tannu-Ola represents basis of regional monitoring of forests of Tuva. And it will help at estimation of prominent features of mountain forests, the resource and ecological parameters defining stability, and also condition of forests and their communication with elements mezorelief. The special place will borrow Digital terain model with slopes and expositions on which will probably allocate features forms of relief of ridge in certain altitude-zone complex of region on expositions and steepness that masking influence of vegetative cover of the stratified mountain relief is very important for exception.
