Sex, estimated age at release, pre-release and release information on the 32 orangutans (OUs, 13 females, 19 males) released and monitored in central sumatra from 2011 to 2013 by means of very high frequency radio tracking.

Individual spatial VHF relocations were used to build the population-level Resource Selection Function (RSF), which estimates OUs’ resource selection in a presence-available design. ‘Used’ locations (i.e., presence) correspond to sites where OUs have been relocated, whereas ‘available’ locations are random points drawn within the population home range (kernel method, 99% isopleth), which define resource availability.
