  1. Provide/increase anti-poaching patrols

    A before-and-after study in 2005–2012 in a tropical dry forest reserve in the Western Forest Complex, Thailand (Duangchantrasiri et al. 2016) found that as anti-poaching patrols intensified, poaching incidents decreased, but the estimated tiger Panthera tigris abundance did not change significantly over seven years. The estimated tiger abundance was similar seven years after poaching patrols started to increase (56 tigers) compared to the year before poaching patrols started to increase (51 tigers). In the final two years of the study, when patrols were at their highest levels, there were 22 poaching incidents detected/1,000 km patrolled, compared to 24–30 incidents/1,000 km patrolled over the previous five years. The study was conducted in a 2,780-km2 reserve, adjacent to approximately 30 villages. In 2006–2012, there was an increase each year in the number of patrol days/year (from 1,031 in 2006 to 3,316 in 2012) and distance patrolled/year (5,979 km in 2006 to 12,907 km in 2012). Tigers were surveyed annually between 2005 and 2012, using camera traps across 524–1,094 km2 (137–2,000 locations/year, 910–3,869 camera-trap days/year). Paired camera traps were positioned along anticipated tiger travel routes.
