Study area.
<p>Map of the study area showing the two plantation areas and the adjacent Kutai National Park and its location in the east of the island of Borneo. Black lines indicate the location of the midlines in the SRH planted, unplanted and conservation areas, and non-randomly placed transects in other parts of the two plantations as well as the buffer zone with Kutai National Park.</p

Crop raiding intensity in different villages across Kalimantan.
<p>High  =  reported conflict frequency every week; Medium  =  every month; Low  =  once a year or less frequently.</p
Potential distribution area of orangutan in Central Kalimantan (yellow), West Kalimantan (purple) and East Kalimantan (green), and the village area boundaries within these regions.

Overview maps of forest cover and orang-utan data points in combination with the orang-utan distribution and land use types.
<p>a) Remaining forest cover in 2010. The sample of 558 orang-utan points used to model habitat is shown. b) Concessions and protected areas in 2010, c) The modelled orang-utan spatial distribution. d) Orang-utan distribution and overlap with protected areas and concessions.</p

Contextual layers used for the generation of the orang-utan distribution.
<p>Note: Layer correlations (Using ENMTools <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0049142#pone.0049142-Warren1" target="_blank">[84]</a>) were lower than 0.5 except for elevation with slope and rugosity. All three layers were maintained in the final analyses since they are of different importance for orang-utans.</p
Orang-utan distribution area in protected areas and concessions.
<p>Note: Areas in this Table are expressed in km<sup>2</sup>. IOPP: industrial Oil Palm Plantation; ITP: Industrial Timber Plantation.</p><p>For Sabah data on oil palm plantations concessions were not available.</p
Contributions of contextual layers to orang-utan Maxent model.
<p>Note: validation model values are the mean, min-max values from a 10 fold validation model ran with the same data in Maxent.</p
