Research To Develop Contraceptive Control of Brushtail Possums in New Zealand
Common brushtail possums are serious pests in New Zealand, where they threaten the survival of native plants and animals and spread bovine tuberculosis. A National Science Strategy Committee established in 1991 to coordinate possum research gave high priority to research aimed at biological control of possums, particularly contraceptive control. Surveys are identifying pathogens and potential v...
متن کاملAerial Prefeeding Followed by Ground Based Toxic Baiting for More Efficient and Acceptable Poisoning of Invasive Small Mammalian Pests
Introduced brushtail possums (Trichosurus vulpecula) and rat species (Rattus spp.) are major vertebrate pests in New Zealand, with impacts on conservation and agriculture being managed largely through poisoning operations. Aerial distribution of baits containing sodium fluoroacetate (1080) has been refined to maximise cost effectiveness and minimise environmental impact, but this method is stro...
متن کاملLong-term dynamics of a fragmented rainforest mammal assemblage.
Habitat fragmentation is a severe threat to tropical biotas, but its long-term effects are poorly understood. We evaluated longer-term changes in the abundance of larger (>1 kg) mammals in fragmented and intact rainforest and in riparian "corridors" in tropical Queensland, with data from 190 spotlighting surveys conducted in 1986-1987 and 2006-2007. In 1986-1987 when most fragments were already...
متن کاملSign Left by Brushtail Possums after Feeding on Bird Eggs and Chicks
Brushtail possums (Trichosurus vulpecula Kerr) have been identified as predators of adult birds, eggs and chicks. A captive possum caught and partially ate a house sparrow (Passer domesticus L.) (Morgan, 1981), and time-lapse video photography recorded wild possums eating kokako (Callaeas cinerea wilsoni Gmelin) eggs (Brown, Innes and Shorten, 1993) and chicks (Innes, Crook and Jansen, 1994). A...
متن کاملA review of the potential of fertility control to manage brushtail possums in New Zealand
Brushtail possums (Trichosurus vulpecula) were introduced into New Zealand from Australia in the mid-1800s and became a major invasive pest. They damage native biodiversity by browsing and predation, and they are a disease risk to the livestock industry by acting as vectors of bovine tuberculosis (TB). Management of possums includes their eradication from some offshore islands and control by tr...
