Control of Bennett's and tammar wallabies in New Zealand using compound 1080 gel on foliage baits
1990
Warburton, B. (Forest Research Inst., Christchurch (New Zealand))
Compound 1080 in a carbopol gel was spread on the foliage of palatable plants to assess its effectiveness in reducing numbers of Bennett's and tammar wallabies. Numbers of Bennett's wallabies were reduced by 91 percent and tammar wallabies by 87 percent. These kill estimates compare favourably with those achieved using aerially sown baits. The costs per hectare of gel poisoning were estimated to be as little as 40 percent of those for aerial baiting, but the costs of using gel will increase as the control areas become larger, more rugged, and less easily traversed on foot.
