Abstract

Temporal data set of Landsat scenes was applied to analyze vegetation cover dynamics within watershed of Angara and Yenisei rivers caused by Siberian silkmoth outbreak (1994 – 1996). yr). A method of generation of sketch-maps time series based on decomposition of scenes by dominating land cover types was developed and applied. It was found 25 % mortality of dark- needle stands. About 15 % of damaged stands recovered after outbreak. The burned area within outbreak zone increased. Decreases of clearcuts were observed, as well as transformation of agriculture land into sparse stands and grass-bushes communities.
