establishing a forest reserve. These involved negotiations with Pete villagers, most of whom occupied the area in which it was intended to establish the forest reserve. The Jozani Forest Reserve was formerly established and gazetted in 1960 and covered 194 ha. In 1965 the FR was expanded to 590 ha. A further expansion was implemented in 1980 when it was expanded to 2,512 ha. A complete ban in consumptive use of forest trees was imposed in 1992 when removal of fallen trees from the reserve was banned. 4
2.0 THE SURVEY AREA 2.1 Location The study area is located on the main Zanzibar Island (Unguja) (Map 1, Map 2) some 35 kilometers from Zanzibar town. It is situated between E 39° 34’, S 6° 16’ (Northwest corner) and 39° 45’, S 6° 28’ (Southeast corner). 2.2 Scope The area of the Proposed Jozani-Chwaka Bay National Park (PJCNP) is 57.7 sq. km. This excludes the Mapopwe Village enclave whose area is 0.7 sq.km (see Map 2, Map 4). The Proposed National Park falls within the Unguja Kusini administrative Region and includes Kati and Kusini districts. The study area is within the following Shehias (wards): Cheju, Unguja Ukuu, Charawe, Chwaka and Jozani-Pete. 2.3 Accessibility The Proposed National Park is located between two major tarmac roads. One tarmac road from Zanzibar town to Unguja Kusini Region through Tunguu passes through the southern part of the Proposed National Park. Another tarmac road from Zanzibar town through Dunga to Chwaka Bay passes through the northern part of the proposed national park. Between the two tarmac roads, there are interconnecting gravel roads running in north-south direction. One runs from Jendele to Mpirani through Kisomanga crossing the Proposed National Park. Another road runs from Jozani to Charawe on the eastern side forming the boundary on that side. From this road, there are a few roads generally running in an east-west direction. One such road goes to Wangwani salt marshes (see Map 2, Map 4). 2.4 Topography Altitude in the proposed National Park ranges from sea level to around 31 meters on the western side of Kitongani village and southeastern part of Mapopwe village. Jozani forest has the lowest altitude point on Zanzibar Island (see the Digital Elevation Model Map 3). 2.5 Geology The geology of the Jozani, Chwaka and surrounding areas is predominantly limestone formed during the Quaternary, through to the Miocene. Whereas the Jozani forest area is mainly comprised of Quaternary geologic formations, the remaining areas including Chwaka, Unguja Ukuu, Ukongoroni have a mixture of Quaternary and Miocene geologic formations.
