­­Medicinal Plant Use and Trade Among the Samburu People in Maralal Town, Kenya

Background: The Samburu people have for the longest time used traditional knowledge on medicinal plants to treat diseases both in human and livestock due to the attributed belief of how effective they are. I set out to understand medicinal plant use and trade among the Samburu community in Maralal town. The objectives of this study were to; (1) identify and document the medicinal plants traded, (2) record the medicinal uses of identified plants, (3) document the parts of the plant used and methods of preparation. Method: I conducted market surveys and held in-depth discussions with the traders on what plant parts were used and sold and where they collected and sourced their plants. I also joined collectors in the wild and collected samples for further identification. Results: From the market surveys, a total of 24 plants species from 16 families were traded. Most of the plants were collected from Kirisia Forests Reserve and the arid shrublands within Samburu County. It was noted that Myrsine africana L., Rotheca myricoides (Hochst.) Steane & Mabb., Rhamnus staddo A.Rich., Salvadora persica L. and Toddalia asiatica (L.) Lam were the most popular species with buyers. Most of the plants were used to treat multiple ailments. Stomach related problems and respiratory disorders were some of the commonly treated ailments. Conclusion: It is evident that use and trade of medicinal plant is an important economic activity in Maralal, however; overharvesting plants from the wild has contributed to some species like Osyris lanceolata Hochst. & Steud (East African sandalwood) and M. africana becoming rare and scarce hence the need to establish conservation measures and sustainable exploitation.

An isolated population of the southern scrub-robin (Drymodes brunneopygia) in the Great Victoria Desert

From 2013 to 2015 we recorded an isolated, highly fragmented and previously undocumented population of the southern scrub-robin within the arid shrublands of the Great Victoria Desert. In this region, the southern scrub-robin persists in scattered and intermittent areas of long-unburnt mulga (Acacia spp.) shrubland, with a dense shrubby understorey dominated by Aluta maisonneuvei and Eremophila shrubs. The Great Victoria Desert supports the only known desert population as the southern scrub-robin otherwise occurs in the temperate and semiarid shrublands of southern Australia and occurs in the desert at the arid extreme of its range. Fire is highlighted as a significant threatening process due to the species’ restricted occurrence (less than 5% of the landscape in the region), low reproductive rate, limited dispersal capability and persistence within long-unburnt and fire-sensitive habitats. As forecast environmental changes are likely to render the arid extremes of the species’ range unsuitable, this outlying, desert population is potentially declining and of conservation significance.
