Written Submissions Environment Australia Part I Volume 2 Cane Toad Inquiry Report 117 ATTACHMENT E Summary of current studies on cane toad impacts on native fauna in the Northern Territory This is an informal list of researchers who are undertaking studies that will provide data on the impact of cane toads on native fauna. It was derived from discussions between Parks Australia staff, NTU staff, PWCNT staff and other researchers. It should not be regarded as a definitive list as it is possible that other projects that will contribute information on the effects of cane toads may have been missed. Taxa Location Agency/person responsible Type of study Status Notes Varanus spp. Kakadu National Park Dan Holland Jabiru 89792415, DCHPARS@aol.com (in conjunction with Key Centre Tropical Wildlife Mgt - NTU) Radio telemetry study, pop. size estimates and road surveys of goanna sightings In progress Intensive radio tracking study of ca. 50 individuals of V. panoptes, plus captures and sightings data on V. gouldii, V. mertensi and V. mitchelli Varanus spp. Near Darwin and Maningrida Tony Griffiths & Tim Schultz (NTU- KCTWM) tony.griffiths@ntu.edu. au Radio telemetry study In progress Dragon (Lophognathus temporalis) Near Darwin Tony Griffiths & Tim Schultz (NTU-KCTWM) tony.griffiths@ntu.edu. au Mark recapture In progress Varanus tristis and Varanus scalaris Kakadu National Park Sam Sweet sweet@lifesci.ucsb.edu Radio telemetry study Complete Behavioural ecology study indicated little likely temporal or spatial overlap between foraging goannas and juvenile (prey-sized) toads in woodlands distant from water. However both species are likely to be impacted where their home range overlaps wet habitats that can support toad breeding or toadlet activity. V. tristis at greater risk as home range is ca 12 ha cf to ca. 1 ha for V. scalaris. Frogs Roper River and Kakadu National Park Gordon Grigg, Uni Qld ggrigg@zoology.uq.ed u.au "Toadpoles" - automated frog call recording devices. In progress Ten sites (five pairs) between Mataranka and 120 km east on Roper valley Hwy. Six sites within KNP replicates in each of three habitats. Counts of relative abundances based on calling frequencies will allow detection of gross changes in frog populations before and after toads. Frogs and reptiles Mary River Kerry Beggs & Peter Whitehead, NTU Peter.Whitehead@ntu. Habitat and fauna surveys In progress Yield data on herp/toad interactions and toad capacity to exploit grasslands of different
