The effect of tropical forest modification on primate population density and diversity

This data represents orang-utan nest survey data, collected to investigate the effects of habitat disturbance on orang-utan populations. Our surveys were conducted in and around the SAFE project site, including areas of Ulu Segama forest reserves and surrounding oil palm estates, covering a total study area of ca. 13,000ha. We conducted nest surveys between April and August 2017, using the standing crop method. Transects were surveyed once by teams of two to four people walking at a steady pace of roughly 0.5km/hr. The data primarily contains perpendicular distances from directly under each nest we encountered to the transect line. We assigned a decay category to each nest, ranging from 1 (new nest) to 5 (heavily degraded). Additionally we recoded the location of each nest, the height of the nest and DBH of the host tree.
