Abstract

Sahastradhara sulphur stream is a natural perennial hill stream which originates from the upper mountainous terrains of Mussoorie in Garhwal region. The climate of Garhwal region depends on the temperature variability. on monthly and seasonally changing patterns. Sahastradhara stream had a cool and pleasant climate but at current stage it has changed at a great extent due to natural and anthropogenic factors. In the present study, the changes were recorded as annual average temperature (3.4 °C – 38.3 °C), wind velocity (0.9 km - 2.5 km), rainfall (225 mm – 371 mm), precipitation and sedimentation rate just double from two decay periods. Twenty tree genera of macrobenthic organisms in sediments and other existed native species of macrophytic vegetation in littoral zones of stream. The physico-chemical characteristics of Sahastradhara hill-stream showed seasonal variations and influenced the distributional patterns of macrobenthic communities.  Presently, eco-biological characteristics of Sahastradhara stream exhibited continuous degradation nature in and around stream ecosystem in terms of biological productivity and macro-benthic diversity.
