“…The massif is known as Dabida Hill, with an elevation of 1400-2200 m. Forest patches on Dabida Hill included in this study are Ngangao (120 ha), Chawia (86 ha), Yale (16 ha) and Vuria (\1 ha). Ngangao is located on a steep eastern slope of a north-southoriented ridge at 1700-1952 m. Chawia is located at the top of a cliff and has gentle slopes between 1470 and 1600 m. Yale is located on a north-southoriented mountain ridge with very steep slopes between 1750 and 2104 m (Pellikka et al 2009 (Beentje and Ndiang'ui 1988;Bytebier 2001;Pellikka et al 2009). …”

“…In Taita Hills, this forest type is represented on the four main peaks (Mbololo, Ngangao, Chawia and Sagalla). The keystone species, Ocotea usambarensis and Podocarpus latifolius, have been extracted for timber in the past and now only occur in small diameter classes (Bytebier 2001;Mbuthia 2003). Vuria and Yale may be high altitude, degraded variants.…”

In the Taita Hills in southern Kenya, remnants of the original Afromontane forest vegetation are restricted to isolated mountain peaks. To assess the level of degradation and the need for forest restoration, we examined how forest plant communities and their indicator species vary between and within remnant patches of cloud forest. We used ordinal abundance data to compare plant communities in eight forest fragments. We also analyzed data on the diversity and abundance of trees in 57 0.1 ha plots to compare tree communities within and between the largest two of these fragments, Ngangao (120 ha) and Mbololo (220 ha). The extant vegetation of the Taita Hills at landscape scale consists of secondary moist montane to intermediate montane forest. There was a high species dissimilarity between fragments (69%). Variation in species composition coincided with an abiotic gradient related to elevation. At plot level, secondary successional species and species of forest edges were most abundant and most frequent. Inferred clusters of plots almost entirely coincided with the two forest fragments. Indicator species associated with forest margins and gaps were more frequent in the smaller of the two forest fragments, while indicators for the larger fragment were more typical for less disturbed moist forest. Abiotic site variability but also different levels of disturbance determine site-specific variants of the montane forest. Conservation efforts should not only focus on maintaining forest quantity (size), but also on forest quality (species composition). Late-successional rainforest species are underrepresented in the woody plant communities of the Taita Hills and assisting restoration of viable populations of cloud forest climax tree species is urgently needed

“…These observations contradict the previously reported panmixia and absence of differentiation in P. taitae populations that was based on morphometric and cytogenetic studies. 4 Genetic studies on other co-distributed avian species present differing scenarios: strong differentiation between fragments and mutation-drift disequilibrium have been reported for the endangered Taita thrush (Turdus helleri), 14 whereas habitat fragmentation was found to have no apparent effect on the dispersal of the white-starred robin (Pogonocichla stellata) between different Table 1. forest fragments.…”

“…2,3 Because of their age, isolated location, and comparatively stable climatic conditions, the Taita Hills are a global biodiversity hotspot characterized by high levels of endemicity. 4,5 Some of the endemic fauna include the Taita reed frog (Hyperolius viridiflavus glandicolor), the Taita thrush (Turdus helleri), the Taita white-eye (Zosterops poliogaster silvanus) and the Taita apalis (Apalis thoracica fuscigularis).…”

The endemic land snail Gulella taitensis of the Taita Hills forests, Kenya: on the brink of extinction

This paper describes the distribution, population size and conservation needs of the land snail Gulella taitensis (Gastropoda: Streptaxidae) endemic to the Taita Hills, Kenya. The species was investigated using timed searches between July and December 2000. In total 37 snails were recorded from only five of nine forest fragments searched. The snail was generally more abundant in the smaller forest fragments. The species appears to be a forest specialist, exhibiting preference for the least disturbed sections of forest. The small population size, restricted distribution and concentration in the smallest and most fragile forest fragments suggests the species is on the brink of extinction. The species fulfills the requirements for changing its conservation status from Endangered to Critically Endangered on the IUCN Red List. Promotion of the Forest Reserves to a conservation category that provides greater legal protection is necessary.
