Project conducted by Laurie Corbett, EWL Sciences. laurie.corbett@ewlscie nces.com.au Wet and post-wet season surveys (in 2002 Study completed. Report inquiries should be directed to Tony Law, Dpt of Defence, Robertson Barracks. Methods included small mammal trapping, pitfall trapping, spotlight counts, diurnal searches, dingo tracking, bird counts; using standardised survey methodology at 24 sites in four major habitats. The study targeted the following indicator species/aggregrates: Predators eating cane toads: dingo, quoll, predatory birds (eg. forest & red-backed kingfishers), snakes and large goannas; Prey eaten by cane toads: beetles and other invertebrates; Competing aggregates of species (for food and breeding resources): frogs; and Indirectly impacted species aggregrates (food eaten by cane toads): small reptiles particularly skinks. Terrestrial fauna (reptiles, frogs, mammals, bushbirds, invertebrates) and aquatic fauna (micro invertebrates, macroinvertebr ates, fishes, waterbirds) Ranger and Jabiluka mining leases in the Magela Creek catchment; reference sites in the Nourlangie Creek catchment of KNP. ERA Ltd - Ranger Mine. Project conducted by Laurie Corbett, EWL Sciences. Wet and dry season surveys in 1994/95 and 2000/01. Study completed. Report completed on 1994/95 data. Draft report for all data currently in preparation. Methods included small mammal trapping, pitfall trapping (vertebrates & invertebrates), spotlight counts, diurnal searches, bird counts; using standardised survey methodology. The data set comprises records from the same sites using similar methods, and thus provides information on changes in species richness and relative abundance over time (6 years). Any future planned monitoring surveys will provide information on cane toad impacts with allowance for natural temporal changes in richness & abundance. Terrestrial fauna (reptiles, frogs, mammals, bushbirds, invertebrates) and aquatic Bradshaw Field Training Area (8710 km2 about 600km southwest of Darwin. Department of Defence, CSIC NT/K, Infrastructure, Robertson Barracks (Tony Law). Baseline surveys Wet and dry season surveys 1996-99. Study with several reports completed. Inquiries about the reports Methods included small mammal trapping, pitfall trapping (vertebrates & invertebrates), spotlight counts, diurnal searches, bird counts; using standard ised survey methodology.
