Capacity for recovery in Bornean orangutan populations if both forest fragmentation and offtake are limited

<p>Spatial layers to run RangeShifter for orangutan populations across Borneo for the three subspecies (<em>Pongo pygmaeus &nbsp;pygmaeus, P. p. wurmbii </em>and <em>P. p. morio</em>).</p> <p>Each subspecies has four associated layers, defined for two fragmentation scenarios Status quo (current levels of fragmentation) and Extreme fragmentation (fragments less than 5,000 ha removed). 1). Habitat, defines the 1/b values for populations intersecting the specific habitat types. 2). Patches, delineates discrete areas of suitable orangutan habitat, each with a unique ID. 3). Resistance, accumulative cost to an orangutan of moving across that landscape and 4). Start_patches, specifies which patches should be initialised with orangutans present at year 0 of the model run.&nbsp;</p>
