Book excerpt: Department of Conservation (DOC) surveillance programmes to detect rodent invasions on rodent-free islands currently involve observation of rodent interference with toxic baits in bait stations. Different DOC Conservancies use different types of bait station. We monitored the behavioural responses of 24 wildcaught captive ship rats (Rattus rattus) to four currently used bait station types; yellow plastic pipe, wooden box ("rat motel"), wooden tunnel, and white plastic Philproof bait stations. The bait stations contained non-toxic bait similar to the toxic bait used in surveillance programmes. More than 75% of the rats entered the yellow plastic pipe, wooden box, and wooden tunnel bait stations, but fewer than 10% entered the Philproof bait stations. Rats ate bait from the first three bait station types but not from the latter. The average amount of bait eaten per night by the rats that ate bait (0.8 g) was not enough for a lethal dose for 50% of the population if the baits had contained 20 ppm, or even 50 ppm, brodifacoum. On the basis of these results, DOC should use yellow plastic pipe, wooden box, or wooden tunnel bait stations rather than Philproof bait stations for surveillance for ship rats. However, other bait station types and the responses of kiore (R. exulans) and house mouse (Mus musculus) to different bait stations should be tested before any final decision is made on the best type to use in multispecies rodent surveillance programmes.

Available in PDF, EPUB and Kindle. Book excerpt: The Handbook of New Zealand Mammals is the only definitive reference on all the land-breeding mammals recorded in the New Zealand region (including the New Zealand sector of Antarctica). It lists 65 species, including native and exotic, wild and feral, living and extinct, residents, vagrants and failed introductions. It describes their history, biology and ecology, and brings together comprehensive and detailed information gathered from widely scattered or previously unpublished sources. The description of each species is arranged under standardised headings for easy reference. Because the only native land-breeding mammals in New Zealand are bats and seals, the great majority of the modern mammal fauna comprises introduced species, whose arrival has had profound effects both for themselves and for the native fauna and flora. The book details changes in numbers and distribution for the native species, and for the arrivals it summarises changes in habitat, diet, numbers and size in comparison with their ancestral stocks, and some of the problems they present to resource managers. For this third edition, the text and references have been completely updated and reorganised into Family chapters. The colour section includes 14 pages of artwork showing all the species described and their main variations, plus two pages of maps.

Kay Clapperton and published by Science & Technical Publishing Department of Conservation. This book was released on 2006-01-01 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: A recent review of techniques used to detect and control the four introduced rodent species found on the New Zealand mainland and islands (house mice Mus musculus, ship rats Rattus rattus, Norway rats Rattus norvegicus and kiore Rattus exulans) identified the need for better understanding of rodent behaviour. This report provides a review of the published literature on rodent behaviour in relation to control devices, especially bait stations and baits. The review is based on searches of computer databases and information from key researchers on: taste preferences, meal size, neophobia, feeding behaviour, movements, home ranges and territoriality, bait shyness, aversion, resistance, odours, and colour preference. Other aspects of rodent behaviour, including responses to repellents, sounds and traps, are also briefly summarised.

Available in PDF, EPUB and Kindle. Book excerpt: A method was developed to evaluate the responses of groups of wild Norway rats to bait stations. Groups of rats were first acclimated to test arenas of 5.6 m2 which each contained abundant harborage in the form of a covered pallet, drain pipes, and masonry blocks. Activity levels were measured daily by four methods: bait consumption, tracks, fecal counts, and motion detector (actimeter) counts. When activity had stabilized, one bait station containing an attractive nontoxic food and additional actimeters were added to each arena. Daily observations revealed changes in activity around the exterior of stations, time until entry, and the initiation and quantity of consumption of the station bait (unpoisoned EPA meal). In tests using the protocol, replicated comparisons were made of eight "tamper-proof" bait stations having various degrees of design complexity. In general, simpler designs showed more rapid and greater utilization and bait consumption. The method has application to evaluations with house mice and for studies of toxic baits in particular station designs.

This book was released on 2012 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: Context. The importance of oceanic islands in terms of conservation of native species is often affected by the introduction of invasive species. Introduced mammalian predators such as feral cats (Felis catus) and rats (Rattus sp.), have been responsible for population decline and extinction of many native species on oceanic islands worldwide. Christmas Island, located in the Indian Ocean, is an example of how introduced mammals have influenced the population of endemic species even to the point of extinction. Aims. The aim was to monitor the effect of a baiting program for rats as part of the management plan for feral cats and rats conducted on the island since 2010 by the Department of Environment and Conservation. Methods. Twenty rats (ten in each site) were trapped in two study sites (Settlement and Upper Poon Saan). Rats were radio collared and released, and then bait stations were opened containing Racumin paste sprayed with coconut milk as an additive. Key results. The baiting had a mean efficacy of 76.5%, with a significant difference ({2 = 4.650, 1df, P=0.031) observed between the sites (100% at Settlement area and 55.55% at Upper Poon Saan). The mean time of action for the baits for both sites was 5.6 ± 0.6 days and the total mean bait consumption per bait station was 41.6 ± 9.07 g. Conclusions. The results of this study suggest that the type of bait currently in use is adequate but the bait spacing may not be sufficient to control rats successfully on Christmas Island. Implications. It is recommended to place the bait stations without bait in advance so the structure looks familiar to rats in order to avoid bait shyness. It is also recommended to clean up and to remove the rubbish in order to reduce the habitat for rats to aid the control program.
