Sun Bears are a forest-dependent species, favouring interior mature and/or heterogeneously structured primary forests (Augeri 2005). There are two ecologically distinct categories of tropical forest that comprise their natural range, distinguished by differences in climate, phenology, and floristic composition: seasonal evergreen and deciduous forest in the mainland (north of the Isthmus of Kra) and aseasonal evergreen rainforest in Malaysia, Sumatra and Borneo.

Deforestation rates and reported high volumes of hunting and trade throughout the Sun Bear range form the basis for this assessment. Sun Bears are forest dependent species, and, thus area of forest loss is directly linked with population decline.

IUCN red list

Southeast Asia, which comprises nearly all of the species global range, has experienced a higher relative rate of forest loss over the past 30 years than any other part of the world (Sodhi et al. 2004, 2010; Miettinen et al. 2011; Margono et al. 2012, 2014; Dong et al. 2014). Extent of occurrence (EOO) appears to be shrinking, with just a few individuals left in China and Bangladesh, and rapid decline in Vietnam (projected 50–80% decline in the next 30 years). Area of occupancy (AOO) is declining and becoming increasingly fragmented, most noticeably in Borneo and Sumatra. In mainland Southeast Asia, some patches in southern Myanmar, central Thailand, southern Cambodia, and southern Vietnam appear to be completely isolated. Deforestation and degradation is expected to continue into the future. Coupled with this, and the persistent trade in bears and bear parts, sun bear populations are expected to decline even more rapidly in the future.

Hi, I’m Palm Oil Detective’s Editor in Chief. Palm Oil Detectives is partly a consumer website about palm oil in products and partly an online community for writers, artists and musicians to showcase their work and express their love for endangered species. I have a strong voice for creatures great and small threatened by deforestation. With our collective power we can shift the greed of the retail industry and influence big palm oil to stop cutting down forests. Be bold! Be courageous!
