Habitat selection and the conservation status of Fischer's turaco Tauraco fischeri on Unguja, Tanzania

Abstract

We report the results of a survey of Fischer's Present levels of exploitation of natural habitats on Unguja appear to be unsustainable and it seems likely turaco Tauraco fischeri in Unguja (otherwise known as Zanzibar). We estimated the species' range, population that all unprotected forests on the island will be lost within a few years. The range of Fischer's turaco is size and habitat selection using unlimited distance point counts. The main results are: 1) Fischer's turaco is more highly fragmented and the population is likely to be decreasing. This turaco was often observed in places widely distributed in the coral rag zone than previously thought, with an area of occupancy estimated at 56 km2, where other threatened species were also present, suggest- ing that it could be both a flagship and an umbrella 2) the species does not occur in agricultural habitats and tree plantations, 3) within natural habitats it selects species for the implementation of wider habitat con- servation strategies. The conservation status of Fischer's places with denser tree cover, 4) food availability does not diCer between occupied and unoccupied sites, and turaco should be reconsidered, with its IUCN threat- category upgraded from Lower Concern: near threatened 5) the turaco population on Unguja was estimated at c. 1,400 individuals. Only 44% of the population is in to Vulnerable. protected areas, and habitat degradation is occurring at a high rate.
