Abstract

The present study on conservational status of Marsh Crocodiles, Crocodylus palustris has been carried out from the Haleji Lake Wildlife Sanctuary (HLWS) Thatta, Sindh, Pakistan. This research study was carried out during the year of 2006-09. We observed and recorded the total numbers of C. palustris two hundred sixty nine (269) in the HLWLS, among them one hundred seventy nine (179) were adult crocodiles, thirty seven (37) were juveniles and fifty three (53) were hatchlings. Various instances of human-crocodile conflicts were observed including 7 injured and three human causalities. Innumerable types of threats to Crocodiles were also noticed including habitat loss, alteration and soil erosion and mortality due to fishing practices. We were determined that the Crocodile population is increasing in HLWS due to strong conservational strategies and management. The present study suggests that further research to propose strategies to conserve this vulnerable species.
