Major pressures and threats have also been identified. Tree forest species are outstanding economically at the source of many products essential to society (timber, fuel, medicines, food). Therefore, they are 41
prone to decimation from harvesting. Second, they are prominent environmentally, as they are the keystone forest species forming tree canopy and helping to stabilize the environment by fixing CO 2 , preventing soil erosion and sustaining the water reservoir in the ecosystem. The trees are dominant ecologically as they determine a wealth of interactions. Conservation in situ is the primary method to sustain target species from decline and safeguard their genetic resources (Frankel et al. 1995). Table 4.10: Threatened plant species of Ngezi forest reserve, Pemba Species name Pressures and Conservation values Conservation threats measures Afzelia quanzensis Exploited for timber, Not in IUCN; but in Forest Experimental plots fuel wood. Timber Ordinance, threatened for plantation status insufficiently exports trade by (Annon.1902, identified Arabs since 1900. Wood 1966) (Moomaw 1960) considers it as premium timber for high class.
