Goats were liberated on Raoul Island early in the 19th century. Attempts to eliminate the goats commence in 1937 and have accounted for at least 15 000 animals. Since 1972, when annual hunting expeditions began, both the number of goats and the area over which they range have steadily declined and the herd is now […]
This review provides a full description of house cats including their distribution, social organisation and behaviour, as well as their significance to the New Zealand environment. Included is a section on feral cat control.
Wild dogs, including dingoes, may cause substantial losses to livestock. They may also have significant impacts upon the distribution and abundance of native wildlife. However, there is an expectation that the dingo should be conserved because it arrived in Australia prior to European settlement. Furthermore, wild dogs in general may play an important role in […]
This publication contains an analysis, by agriculture researchers, of pest animal distribution and abundance across NSW and ACT, particularly those pests that can impact on the environment and agriculture, and have the potential to act as reservoirs of exotic animal disease. Maps are included.
In New Zealand, the agricultural and horticultural industries view many introduced bird species as significant crop pests. In the arable sector, for example, introduced passerine species, such as house sparrows and greenfinches, cause substantial damage to high-value speciality crops, e.g., radish seed. Bird control techniques currently used by farmers such as scarers, shooting, repellents and […]
Within Western Australia, Perca fluviatilis is restricted to the south-western corner and is found in the Swan, Murray, Harvey, Collie, Capel, Carbunup, Margaret, Blackwood, Donnelly and Warren river systems. Age data suggest it was released into Big Brook Dam (Warren River) in 1992 or 1993, where it has since played a role in eliminating the […]
The distribution and density of red fox populations was investigated in metropolitan Melbourne from 1990 to 1993. Distribution data were collected from sightings reported by members of the public, from spotlight and active den surveys, and from trapping and road kills. Archival data suggested that resident populations of foxes have been present within the inner […]
The former distributions of stick-nest rats (Leporillus conditor and L. apicalis), both extinct on the Australian mainland since about the 1930s, were determined from literature reports, museum records, interview responses and field surveys of key areas. Population parameters were determined for L. conditor from early literature accounts, studies of remnant stick-nests in caves, a three-year […]
Researchers and managers commonly use catch rates on trap-transects as an index of abundance for trappable wildlife species. We describe a method whereby the data collected from such surveys can be further analysed to obtain information on the patchiness of the trapped species’ distribution on those transects. For certain applications, such as the management of […]
We conducted a broad-scale aerial survey between 20 August and 12 October 2001 to ascertain the distribution and abundance of feral camels in the southern part of the Northern Territory. There was a minimum of 80 533 feral camels in the Northern Territory at the time of the survey. This figure is corrected for perception […]
Stoat was popular until the introduction of th domestic cat and intensive game bird management. Territory size 5-200 ha. Heneral summary of biology.
Considers the Irish stoat a representative of an earlier invasion that survived the last glaciation, whereas the British stoat is derived from a later invasion so is not distinct from the European subsp. Stoats on Jura could be a hybrid. In large populations, new subspecific characters do not evolve in
3 species Ictonyx striatus, Poecilictis libica, and Mustela nivalis subpalmata. 23 specimens of palmata, mostly from houses. Eat a lot of cockroaches. In 3 males, total length av 400.4 mm (398-403), tail 117.6 (107-129), CBL 50.1 (48.8-51.2).
