Validation of predicted nest counts on an independent orangutan nest count dataset.

<p>Maps showing the spatial correspondence between orangutan nest counts calculated from (a) <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0043846#pone.0043846-Alfred1" target="_blank">[25]</a> and (b) our model predictions. Note that the model-predicted nest counts are generally lower than the empirically derived estimates.
