Booderee National Park trends in mammal abundance 

Sampling design: Mammal trapping commenced in August 2003 at the same time that intensive fox control began. One hundred traps are placed at 500m intervals along trails throughout the Park, with 50 trap sites in the eastern half of the Park and 50 trap sites in the western half of the Park. This forms two continuous transects of 24.5 km in each half of the Park. 

Mammal trapping: Traps are 20 x 20 x 50 cm wire cage traps, with every fifth trap a 30 x 30 x 60 cm cage trap. One end of the trap is covered by plastic to shelter trapped animals and traps are baited with a mixture of rolled oats and peanut butter. Trapping occurs every three months, over a two week period. In the first week, 50 traps in the eastern half of the Park are open for four nights and checked each morning. In the second week; 50 traps in the western half of the Park are open for four nights and checked each morning. Any bandicoots or possums trapped are weighed, sexed, pes length measured (bandicoots only) and marked with a PIT tag (Trovan ID 100). Females are searched for pouch young or indications of recent lactation. Numbers of bush rats trapped are also recorded.
