pictus), lion (Panthera leo), leopard (Panthera pardus) and perhaps a few black rhinoceros (Diceros<br />

bicornis).<br />

The Zanzibar red colobus (Procolobus kirkii) is also a flagship species on Unguja Island. The estimated<br />

global population is around 2,500 individuals, mainly living in and around the Jozani Forest, but also in a<br />

number of village forests in close association with people. It is not hunted by the Muslim inhabitants of<br />

this island and has become a significant tourist attraction. A few individuals have also been introduced<br />

into Pemba island, but are not doing well.<br />

Among the plants, the main flagship species in the coastal forests are African violets (Saintpaulia sp),<br />

which are only present in a few of the wetter forests, mainly close to the East Usambara mountains.<br />

These plants are globally cultivated as houseplants, but originate in Tanzanian and Kenyan forests. The<br />

Coastal Forests also contain 11 species of wild coffee, of which eight are endemic (Clarke et al. 2000).<br />

None of these have been exploited as commercial crops. There are also important stands of cycads in<br />

some well sheltered areas where fire is not a strong threat, with the common species being<br />

Encephalartos hildebrandtii. Preliminary botanical explorations in the little-known Namatimbili–<br />

Ngarama forest block located some 35 km inland of Kilwa in south-east Tanzania have rediscovered and<br />

further confirmed the presence of two tree species, Erythrina schliebenii Harms and Karomia gigas<br />

(Faden) Verdc., that were previously thought to have become extinct. Both trees are endemic to the<br />

Coastal Forests of Eastern Africa hotspot and to the Swahilian Regional Centre of Endemism (Clarke et<br />

al. 2011).<br />

2.3 Priority Analyses<br />

2.3.1 Simple number of important vertebrates<br />

A simple addition of the forest species of birds, mammals, reptiles and amphibians found in those<br />

Coastal Forests of Tanzania that have been studied, indicates a rough idea of biological priority (Figure<br />

2). This shows that several sites have more than 100 forest species present, East Usambara lowlands,<br />

Gendagenda, Zaraninge (now part of Sadaani NP), Pugu/Kazimzumbwe (now heavily degraded),<br />

Kiwengoma, Litipo, Rondo and Zanzibar Island. The last four of these sites are within the intervention<br />

landscapes of this GEF project.<br />
