Abstract – The banded pig, Sus scrofa vittatus, in the absence of natural predators and hunting pressures, is hypothesized to be hyper-abundant within Singapore’s forests. Their high densities pose a threat to Singapore’s already disturbed forest ecosystems and increases the risk of human-animal conflicts. Despite being a native animal, its role within Singapore’s forest ecosystems has not been fully understood yet. Therefore, there is a need for estimating the absolute abundance of Sus scrofa vittatus and quantifying its effects in Singapore’s forests.
The proposed method is to analyse data, obtained from camera trapping, with a recently developed Spatial Capture-Recapture (SCR) model that overcomes most of the problems encountered by traditional capture-recapture models. Additionally, an exclusion plot study is proposed to quantify both positive and negative impacts the pigs have in Singapore’s forests.
