Soil & Moisture Conservation
Two pronged strategy was adopted to conserve soil & moisture:
Vegetative methods : Massive afforestation including direct seed sowing in contour trenches was carried out on hill slopes on sustained basis to conserve soil. Soil conserving species like Arundo-donex was planted along choe banks to train the choe and to stabilize the choe banks. Special emphasis has been laid to plant and seed sowing of indigenous species of trees, shrubs and grasses. The density of vegetation is very good.
Engineering methods : 190 silt retention dams, more than 200 check dams, spurs, revetments and brushwood structures have been constructed to conserve the soil and to retain the silt in the water-bodies created behind silt retention dams. Fully silted up water bodies have been desilted on regular basis to revive its silt retention capacity. The silt taken out from silted up water bodies has been dumped at appropriate locations in the sanctuary itself and soil conserving grasses, herbs & shrubs are planted over it before onset of Monsoon every year.
The aforementioned soil and moisture conservation measures have led to a remarkable improvement in the underground water regime. Due to series of water-bodies in these seasonal nallahs (choes), there is continuous flow of seepage water throughout the year in few nallahs. The availability of moisture is responsible for good plantations in the sanctuary.
