In India, the natural vegetation distribution depends on three factors: annual average rainfall, length of the dry season, and mean temperature of the coldest month (Gaussen et?al., 1965 and Gunnell, 1997). In mountainous regions, vegetation distribution Mutant IDH1-IN-1 also determined by temperature variations following the altitudinal gradient. However, below 900 m, the amount and seasonal distribution of annual rainfall are the most important factors on the vegetation distribution (Bonnefille et al., 1999). Most of the Godavari and Mahanadi river catchments are located in the CMZ and below 900 m (excluding the highest summits of the Eastern Ghats), and hence the vegetation responds to monsoon influence directly. Therefore, pollen-derived vegetation records from ureter areas will reflect variations in monsoon frequency and magnitude.

Ecological communities have been compiled from seven IFP maps published between 1963 and 1973 by Gaussen and colleagues.Figure optionsDownload full-size imageDownload as PowerPoint slide
