| Bornean orangutan (Pongo pygmaeus) | Bornean orangutans 2019 shapefile (ZIP; 3.48 MB) | Bornean orangutans 2019 geojson(ZIP; 5.35 MB) | 2019 | The layer is an update of the original Voigt et al.2018 layer predicting the Bornean orangutan density distribution. In 2021 Voigt & Wich provided an update of the initial predictions, based on forest lost in Borneo. This new layer does not consider hunting in the predictions and hence might have overestimated the numbers of orangutans. | Voigt & Wich 2021 |
| Sumatran orangutan (Pongo abelii) | Sumatran orangutans 2015 shapefile (ZIP; 398 KB) | Sumatran orangutans 2015 geojson (ZIP; 2.99 MB) | 2015 | Predictive density distribution model for the entire Sumatran orangutan geographic range based on available orangutan presence localities and land land-cover change. | Wich, S. A., Singleton, I., Nowak, M. G., Utami Atmoko, S. S., Nisam, G., Arif, S. M., ... & Kühl, H. S. (2016). Land-cover changes predict steep declines for the Sumatran orangutan (Pongo abelii).
