Extended areas of western and south-western Tanzania are still covered by natural habitats, within the miombo woodland biome. Miombo woodlands are home to a large biodiversity, with a mix of forest and savanna species and in addition species that are endemic to the miombo. In a preliminary study based on a camera trap survey and conducted in Mlele beekeeping zone, a forest reserve located north of Katavi National Park, we were able to confirm the presence of over 50 species of medium sized and large mammals, including 10 species of small carnivores. Among this latter guild some species were surprisingly abundant, such as for example the bushy-tailed mongoose (Bdeogale crassicauda), that was previously considered uncommon, and the miombo genet (Genetta angolensis), a species linked to this habitat but for which there was only few records in and around our study area before our surveys. Since this preliminary study, we have extended our survey protocol and acquired new camera traps with more sensitive detectors. The data we have acquired since then enables us to have a more precise picture of the spatial behavior of these species and to use occupancy models to have a proxy of their abundance and to investigate if natural or anthropic factors might influence their distribution.
