Correction: Quantifying Killing of Orangutans and Human-Orangutan Conflict in Kalimantan, Indonesia

Abstract

Human-orangutan conflict and hunting are thought to pose a serious threat to orangutan existence in Kalimantan, the Indonesian part of Borneo. No data existed prior to the present study to substantiate these threats. We investigated the rates, spatial distribution and causes of conflict and hunting through an interview-based survey in the orangutan's range in Kalimantan, Indonesia. Between April 2008 and September 2009, we interviewed 6983 respondents in 687 villages to obtain socio-economic information, assess knowledge of local wildlife in general and orangutan encounters specifically, and to query respondents about their knowledge on orangutan conflicts and killing, and relevant laws. This survey revealed estimated killing rates of between 630 and 1357 animals killed in the last year, and between 2383 and 3882 animals killed per year on average within the lifetime of the survey respondents. These killing rates are higher than previously thought and are high enough to pose a serious threat to the continued existence of orangutans in Kalimantan. Importantly, the study contributes to our understanding of the spatial variation in threats, and the underlying causes of those threats, which can be used to facilitate the development of targeted conservation management.

Population Status of Tapanuli Orangutan (Pongo tapanuliensis) within the Renewable Energy Development and its Management Implications

“…Those potential natural corridors shall be protected, and an artificial corridor could be added to facilitate orangutans' movement, specifically among the small forest patches (Ancrenaz et al, 2021). It was analyzed that one of the causes of the declining orangutans' population is hunting (Meijaard et al, 2011;Meijaard et al, 2012;Davis et al, 2013;Abram et al, 2015;Voigt et al, 2018;Meijaard et al, 2021). Moreover, Wich et al (2012) observed that hunting for Sumatran orangutan often occurred within lower geographical elevation.…”
