Figure 1 from: Rowson B, Warren B, Ngereza C (2010) Terrestrial molluscs of Pemba Island, Zanzibar, Tanzania, and its status as an "oceanic" island. ZooKeys 70: 1-39. https://doi.org/10.3897/zookeys.70.762

Figure 1 - A Pemba and the surrounding area. Contours: 200m and 1000m (above sea level); 200m (below sea level). The land below 400m, including the islands, roughly corresponds to the Zanzibar-Inhambane vegetation mosaic of White (1983) in which coastal forest fragments are scattered. B sites surveyed on Pemba in 2009, numbered as in Table 1, with forest reserves (shaded areas) and large towns marked.
