of the southern Carnarvon Basin, Western Australia.
Additionally, this project takes advantage of our already established collaboration with IKEA, the Sabah Foundation (Dr. Sauwai Yap and Dr. Waidi Sinun), the Malaysia Forestry Department (Dr. Robert Ong), Bioversity-Malaysia (Dr. Riina Jalonen) as well as researchers connected to the University Malaysia Sabah (Dr. Tockhing Chua, and Dr. Collin Maycock). Pooled across the trapped population, captured (if collared cats included; tabby (n, One hundred and six transects were completed during, the 2015 survey (Phase 2). Many species of Australian native mammals have experienced significant range declines or extinction in the arid zone since European settlement, and many species of birds have suffered similar declines over the same time period 1-7. The existence of island faunas, however, should not be a recipe for complacency, or seen as a solution to the extinction problem. 223 Special Publication No. We conducted an initial camera-trap survey in fox-baited and unbaited sites in the Flinders Ranges, to quantify the impact of fox baiting on the relative abundance of foxes, feral cats and their prey. Among the 48 reptile species living on Dirk Hartog Island are
introduced to offshore and oceanic islands, ) once also occurred on the island as they, ).
Data from May 2014 through to October, 2016 were used to determine detection probability as, this was the period when cats were actively removed, from the island. 10, Australian National Centre of Excellence for Maritime Archaeology, This page was last edited on 30 August 2020, at 11:46. and consists of coastal dunes and undulating plains of.
Bode M, Brennan KEC, Helmstedt K, Desmond A, Smia R, Algar D (2013) Interior fences reduce cost and uncertainty, when eradicating invasive species from islands. Old cat scats, were detected at ten locations during this survey with, at least four of these suspected to be associated with, old trap sets. It was also, necessary to delay the construction of the barrier fence, until after the first baiting.
The fence effectively divided, removal efforts in the two discrete sections of the, island. Copyright © 2020Australias Guide Pty Ltd.
To estimate the probability that feral cats persist on, Dirk Hartog Island, after removal measures, extinction, estimates were calculated using the presence/absence, of signs of feral cats between May 2014 and October, 2018. The Australian Wildlife Conservancy, lease holders of Faure Island Pastoral Lease, is planning to establish the area as a site for the conservation of threatened mammals and ecotourism. (winter 2016) and northern sections (winter 2017)]; and (4) surveillance monitoring for cat activity was, conducted on a seasonal basis for the following two, years prior to the native species reintroductions, as an, insurance policy that no cats had been overlooked or, reintroduced. Commonw Aust, DEWHA (Department of the Environment, Water, Heritage and, the Arts) (2008) Threat abatement plan for predation by, feral cats.
2, is the largest island off the Western.
It is about 80 kilometres (50 miles) long and between 3 and 15 kilometres (1.9 and 9.3 miles) wide and is Western Australia's largest and most western island.
pink snapper from the block. Feral cat eradication took place in autumn 2001 and comprised two stages - an aerial baiting campaign and a follow up ground baiting, trapping and monitoring program.
Some relict populations on 'sensitive' islands are at known or potential risk from these and other extinction-causing factors.
Choice of this, spacing for the monitoring tracks and separation of, camera traps was further strengthened by data col-, lected on home ranges (100% minimum convex, polygon) of the radio-collared cats in the pilot study, Track lines were established parallel to the long, axis of the island and the orientation of the dune, system. 12 days post-baiting) and, was not relocated by VHF nor photographed or, trapped since this time. No cat footprints were observed on any, transects or vehicle tracks while commuting to or from, the search areas by the handlers or support crew. We also benefit from an international network of world leading rain forest researchers active in Sabah including; Dr. David Burslem (Univ. preparation of the southern monitoring track network.

To (1) investigate the impact of a large-scale, long-term fox-baiting program on the abundance of foxes, feral cats and introduced and native prey species in the Flinders Ranges, South Australia, and (2) determine the effectiveness of a short time period of cat removal in immediately reducing feral cat abundance where foxes are absent. At the, completion of the monitoring/trapping operations, a, team of detector dogs and their handlers was con-, tracted to provide independent verification that erad-, ication had occurred south of the barrier fence in, winter 2015 and 2016 and north in winter 2017, (Phase, 2).
control are generally acknowledged as expensive, labour intensive and requiring an ongoing Bicentenary Expedition Committee, Western Australian. the, probability of the cats persisting on the island is less, were used to determine the confidence in surveillance.
Hartog gave the Australian mainland one of its earliest known names, as Eendrachtsland, which he named after his ship Eendracht, meaning "concord". or impacting recreational visitors to the island.
