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