Abstract
Platypus distribution in the Bellinger catchment was investigated using a combination of field and community surveys. The field survey in 1996 consisted of netting and observations from the river bank and a canoe. The community-based wildlife survey consisted of a questionnaire and colour maps on which respondents were asked to mark the locations of sightings. Platypuses were observed or caught in 36 locations from all three rivers of the catchment. Two of the three platypuses captured were lactating females. The community recorded 123 locations of platypuses. The fact that the wildlife survey yielded similar results to the field surveys in identifying the location of individuals highlights the value of community records for platypus surveys. There were major floods in 2001, after which we contacted respondents who had reported seeing platypuses three years before. Of the 21 respondents who had been near the river since the flood, 7 had seen platypuses, principally in the tributaries of the Bellinger River. The habitat quality of the rivers was evaluated for platypuses and records were related to disturbance and rehabilitation. The species has survived in this system, but its future can only be assured by strategies which prevent further degradation of its habitat and institute proactive rehabilitation of the damaged sections of these streams.
