'''Population status'''<br>

The Southwest Bornean orangutan subspecies has experienced a staggering decline of over 50% in the past four decades, which amounts to less than two generations (Meijaard et al. 2011), resulting in the disappearance of many small populations (Abram et al. 2015). The precise total population of Southwest Bornean orangutans remains uncertain, but the majority of their habitat exists beyond designated conservation areas (Ancrenaz et al. 2016). Historically, several populations within protected zones such as Sebangau National Park and its environs, boasting the largest orangutan population in Borneo (Wich et al. 2008), along with Tanjung Puting National Park and [[Gunung Palung National Park]], were thought to be relatively stable. Overall, the subspecies is projected to decline by more than 86% in three generations (1950–2025), warranting its classification as Critically Endangered. The population trend for all subspecies of Bornean orangutans is decreasing (Voigt et al. 2018).
