Demonstrating the existence of trends in monitoring data is of increasing practical importance to conservation managers wishing to preserve threatened species or reduce the impact of pest species. However, the ability to do so can be compromised if the species in question has low detectability and the true occupancy level or abundance of the species […]
In the present paper, we have provided an initial assessment of the current and future threats to biodiversity posed by introduced mammals (predators and herbivores) inhabiting the Australian rangelands, exploring trends in populations and options for management. Notably, rabbits have declined in recent years in the wake of rabbit haemorrhagic disease, populations of feral camels […]
One of the greatest challenges in endangered animal species management is estimating abundance of endangered animals and the feral pests that contribute to their endangerment. Current methods for estimating abundance and recruitment involve either observation of tracks and signs (which are not easily related to absolute abundance) or capture, mark and release of individuals. Such […]
A capture-status alarm system was developed to be used in conjunction with a humane snare device used for control of wild canids in Victoria. The alarm unit transmits a unique identity code as well as indicating the capture status of the snare. Large numbers of alarm units can be allocated to a single frequency as […]
Over 400 landholders on central and western Eyre Peninsula, South Australia, are involved in the West Coast Integrated Pest Management Program, a Natural Heritage Trust-funded program which is managed by a partnership of four state and regional agencies. Central to the philosophy and success of the program is a coordinated, landscape scale approach to pest […]
This Landcare Note gives advice on techniques for monitoring rabbits.
The National Feral Animal Control Program (NFACP) has been established under the Australian Government’s Natural Heritage Trust to develop and implement, in cooperation with State, Territory and Local Governments, a program to reduce the damage to agriculture caused by pest animals. The focus of NFACP is applied research/demonstration projects which are likely to have a […]
1. Trapping and hunting records are frequently used as an index of animal abundance. This study demonstrates that these records can be misleading if sampling effort is not controlled for. 2. Mean numbers of stoats Mustela erminea and weasels M. nivalis trapped by British gamekeepers have been decreasing since 1975 and 1961 respectively, giving rise […]
Tracking indices collected once a season from 30 sites using DOC standard protocol. In podocarp/kauri forests where stoats were controlled, indices of rat abundance higher and of mouse, lower. Good calibrations of tunnel indices for rodents and mustelids against trapping indices.
The characteristics of the guard hairs of all the mustelids in Hungary and Vulpes vulpes and Felis silvestris were examined for diagnostic characters. The analysis of hair samples taken from guts, scats, burrows, nests and bait sites can serve as an casy and quick method for faunistic research. The difficulties of hair determination are the […]
