 ABSTRACT

The threats on riverine ecosystem increasingly harshly, it include sand mining, stone quarrying, illegal fishing, water extraction, riverside agriculture and such other activities posing the adverse impact on the wildlife in NCS. The present study was conducted in NCS Rajasthan during the session of 2015 to 2018 and observations were taken by using opportunistic Search and Stationary Count Method. The Sand mining and Fishing are considered as direct threat for the aquatic fauna in NCS. The sand mining were observed by various mechanical and manual means. The Water extraction for irrigation by engine pumps were recorded number of water pumps per km. The fisherman presence, fishing nets and ferries were observed in a large amount. The observed gharial population was 671.75±118.14 per year with encounter rate of 1.6 per km. The lower stretch have good habitat matrix for gharial to perform different seasonal activities and in lack of other such habitats in upstream section, gharial population is being concentrated in lower stretch and compromising with the situation for their survival. In upcoming year, it is possible that in such area where the anthropogenic threats continuously increasing might cause a drastic damage to gharial habitat and can badly affect the upstream gharial population.

Key word: Gharial, Threats, Mean, Riverine ecosystem, Habitat.
