Environmental influence on the spatial abundance of tiger prey monitored using camera traps in Thap Lan and Pang Sida National Parks, Thailand

A study in Thailand's Dong Phayayen-Khao Yai Forest Complex reveals critical environmental factors influencing the spatial abundance of five key tiger prey species: gaur, banteng, sambar deer, muntjac, and wild boar. Using advanced camera-trap data analysis models (REST and Royle-Nichols), researchers found that vegetation cover, proximity to human settlements, elevation, and salt licks significantly impact prey densities. Muntjac and wild boar consistently showed higher densities, with estimates ranging from 1.05 to 3.06 individuals per km² depending on the model used. These findings provide a novel framework for predicting animal density, offering crucial insights for conservation strategies aimed at sustaining tiger populations in this UNESCO World Heritage Site.
