Abstract

Counts were made of Salt-water Crocodiles (Crocodylus porosus) in the estuarine portions of the Glenelg, Prince Regent and Ord River systems of the Kimberley Division, Western Australia. During the survey 581 crocodiles were seen, including 143 hatchlings. The number of non-hatchling crocodiles in present the Glenelg system is estimated to be 200 to 259, in the Prince Regent 190 to 246 and in the Ord 235 to 306 (95% confidence limits).

The number of non-hatchling crocodiles present in the six Kimberley river systems now counted is estimated to be between 957 and 1243 (95% confidence limits) and we believe that this constitutes more than half of the total Western Australian non-hatchling crocodile population which is estimated to be, at the most, about 2 000. The potential for the recovery of the Salt-water Crocodile population in Western Australia is not good and culling for the hide trade should not be allowed.
