Map of Gombe National Park, Tanzania.

The 2007 ranges of the habituated Kasekela (brown) and Mitumba (blue) communities are shown in relation to minimal (solid lines) and likely (broken lines) ranges of the unhabituated Kalande (orange) community. The inset depicts the location of Gombe within Tanzania. Yellow circles indicate observed locations (2002–2009) of Kalande chimpanzees (within the park) and their nests (outside the park). Vegetation cover is colored based on classification from remote sensing as beach/grassland (yellow), open woodland (light green), thicket woodland (medium green), or evergreen forest/vine tangle (dark green).
