Coal & Allied – Hunter Valley Operations 5.2.13 Feral Animal Control As part of HVO’s Vertebrate Pest Action Plan, a control programme is carried out on a quarterly basis. Each quarter, the results from the previous programme (along with any focused control required) are considered to plan the following control programme. Throughout 2009, control was based on a comprehensive baiting programme to target wild dogs and foxes using meat-based baits injected with sodium monoflouroacetate (commonly known as 1080). Feral cat cage traps were also used on three occasions at HVO. Table 63 summarises the vertebrate pest control undertaken at HVO during 2009. Table 63: Vertebrate Pest Control Summary 2009 Total Lethal Baits Laid* Wild Dog Takes Fox Takes Feral Cat Cage Trapping Sandpad Monitoring Summer 144 3 14 Trapping undertaken ( 0 cats caught) - Autumn 189 9 22 - Monitoring undertaken Winter 189 5 30 Trapping undertaken (7 cats caught) Spring 198 4 35 Trapping undertaken (0 cats caught) - Monitoring undertaken Total 720 21 101 - - * Cumulative number of baits presented at each check. Sand pad monitoring was used twice during the reporting period to monitor feral animal abundance. Strips of clay-rich bush sand were laid across tracks to record prints of animals moving through the area. Species abundance figures were calculated using methods based on research carried out by the CSIRO and DECCW. Table 64 presents the resultant species abundance figures. Figure 83 illustrates the areas in which feral animal control was conducted at HVO in 2009. Due to the small scale, cat trap locations are not shown on the figure. Traps were located around the main administration block and the CPP.
