WWF FROGS! Program Written Submissions Cane Toad Inquiry Report Volume 2 76 These reports will tend to be somewhat more reliable than sight records from the public, but they will nevertheless also require verification. c. begin training a Cane Toad Patrol who will become conversant in the biology of cane toads and skilled in conclusively verifying the occurrence of toads at reported localities. They must be trained to find and positively identify all cane toad life stages, e.g. eggs, tadpoles, juveniles, adult males and adult females. They will verify sightings from the public reporting network by visiting the sites and will assess the biophysical nature of the site and the densities of toads at the site. Their GPS measured site records will be coded as verified. Eradication skills and training detailed below (see 4a). d. hire a GIS Database and Reporting Manager who will receive and plot the reports from the public, from the volunteer observers network, and from the Cane Toad Patrol. This person will oversee the quality control and synthesis of in-coming data and will interpret it for the rest of the program team and the public through up-dated maps, a website and routinely released reports. e. a Volunteers Co-ordinator will work in concert with the Database Manager and the Cane Toad Patrol to enlist, expand and maintain a corps of volunteers to report cane toad sightings. A primary goal will be to maximise the geographical coverage of the target region. f. develop a media network to broadcast to the public the latest information on the progress of the scientific program and to encourage public participation and vigilance. 2. Conduct an in-depth analysis of the geography of the NT and cane toad dispersal into the NT a. identify topographical and other relevant geographical features of the region that provide toads with unimpeded or impeded dispersal corridors, bottlenecks, dead-ends, or distributional fragments b. plot the nature and extent of these geographical features and develop a system that divides the region into a mosaic of fragments or isolates based upon the regions innate biophysical character c. divide up the whole region into manageable units in which eradication can be carried out in relative isolation from adjacent units d. rank these geographical units based upon relative invasion rates and identify locations where the perimeter is known to be most rapidly expanding or likely to expand these will be given the highest priority e. develop an overall systematic eradication strategy that will halt further progress of the invading toads, contain them within the current limits, then systematically eradicate populations working from the perimeter 3. Begin an on-ground survey of the north eastern boundary region between the Northern Territory and Queensland. a. assess the logistical problems associated with maintaining an effective 30 km wide by 150 km long Toad Control Zone between Queensland and the Northern Territory, e.g. current extent of cane toad distribution; accessibility and manoeuvrability within the terrain; supply routes; seasonality factors, infrastructure. b. as quickly as possible, commence an intensive systematic and sustained detection and eradication program throughout the length of the Toad Control Zone to keep toad migrations into the control zone from within and without the Northern Territory to an absolute minimum.
