“…After the establishment of the village in 1975 (Kumburu 2002) in a region of more or less continuous Acacia woodland, a large proportion of the woodland has been cleared for agriculture (Krog et al 2005), mostly maize fields and pasture. The remains of the former woodland are now patches of bushland with a canopy cover of 40% or more, consisting of 3-7 m high woody plants (Beentje 1994), predominantly Dyschoriste sp., Dichrostachys cinerea, Indigofera swaziensis, Acacia pentagona, Hoslundia opposita, Acacia senegal, Acacia nilotica, Munduleae sericea, Lannea humilis and Acacia tortilis (Hansen and Theilade 2005). According to the local people, large wild herbivores including elephant, giraffe and rhino used to be abundant until the 1970's, but today none remain, and small herds of cattle, sheep and goats graze in the bushlands (Gervin 2003).…”

“…The ecosystem services provided by these patches of semi-natural habitat are essential for the local people who rely on bushland for e.g. medicine, firewood and timber (Krog et al 2005). Although humans have obviously impacted natural systems by fragmentation and isolation, the exact effect on animal assemblages, particularly invertebrates, is poorly known.…”

Deforestation and biodiversity: effects of bushland cultivation on dung beetles in semi-arid Tanzania

Dung beetles provide important ecosystem services in the habitats where they occur. The activity of dung beetles enhances soil nutrient cycling and increases the soil's ability to absorb and hold water. Consequently, these beetles are particularly important in semi-arid environments. This study analyses the importance of remaining wooded habitat patches (bushland) for the survival of a diverse dung beetle fauna in an otherwise cultivated landscape in semi-arid Tanzania. Dung beetles were sampled by pitfall trapping in maize fields and bushland habitats. In total, 6037 dung beetles (Scarabaeidae: Scarabaeinae), representing 77 species from 25 genera, were collected. Many species, particularly amongst the ball-rollers, showed a clear preference for wooded patches, species richness being significantly higher in the bushland patches than in the cultivated sites. The number of trapped specimens in bushland was also considerably higher than that found in maize fields, although the differences were not significant. In conclusion, bushland fragments appear to have an important conservation value as to maintaining a high diversity and abundance of dung beetles, thereby enhancing the ecosystem services provided by these beneficial insects.

“…About 95% and 4% of the population used firewood and charcoal for cooking while only 2% of the population used firewood for lighting [14]. Trees are widely used for production of charcoal, firewood, timber and burning of bricks [17] as well as for construction materials, building-poles [18][19][20], and construction of houses [21]. Charcoal and firewood are produced from a wide variety of tree species [22].…”

“…Social scientists, development institutions, and now conservationists have been promoting the incorporation of local environmental knowledge to the success of policy and action (Warren et al 1995;Ticktin and Johns 2002;Krog et al 2005;Oba and Kaitira 2006). However, despite the increase in rhetoric (Cheveau et al 2008), many managers and researchers still struggle to engage local knowledge holders fully in conservation research and action (Stringer and Reed 2007).…”

This paper examines the process and outcome of participatory methods for stakeholder identification. We used focus group style participatory methodology to engage local residents in identifying key sub-groups relevant to conservation in Boumba, Niger. We then conducted a quantitative pictorial recognition study to measure the diversity of local useful plant knowledge across groups. The community identified six gender and age-class groupings relevant to the study. The effect of a participant's gender, socially-defined age class or the interaction of the two factors on the number of plants recognized varied by plant use. Medicinal plant knowledge was highest among elders. Food plant knowledge of food plants increased with age for women only. Where as the interaction of age and gender was strongest on fodder plant knowledge, where mid-aged men scored highest. We reflect on the impact that heterogeneity of local botanical knowledge has on our understanding of local natural resource use and the strengths of using a participatory approach to identifying the stakeholder groups which underlie this heterogeneity.
