Abstract:
During the past three years the bait interference method of opossum, density assessment has been developed as the main tool for assessing both opossum densities and the success of aerial poisoning operations in exotic forests within the Rotorua Conservancy. Although there have been a few problems in the application of the method, results obtained have been in good agreement with field observations and other density estimates.
