The Shannon Weaver diversity index takes into account the number of individuals for each species as well as the total number of species. The highest species diversity was observed in Jozani forest plantation and Wangwani and Tovu forests (Table 14). The wet forested areas showed a high species diversity. Bondeni natural forest and Unguja Ukuu forest plantation showed the lowest species diversity. Figure 8 indicates the number of species for different animal groups found on Zanzibar. 4.2.4 Important habitats for animals Different animal groups occur in different habitat types (Table 15). Although certain animals can occur in a variety of habitats but there are habitats which are more ideal for a species or taxonomic group. Most mammals utilise the forest and thicket habitats as they provide both 57
