Descrição
The dataset represents 501 mammal records. This include 213 occurrence records of mammal species recorded in a field expedition undertaken in mid Tana River Basin (TRB) ecosystem (Bangal, Garissa, Bura and Hola), in between 1st to 7th November 2019. A total of 38 different small and medium sized mammal species of 11 orders were recorded from above expedition. Order Cetartiodactyla (Even-toed Ungulates), Carnivora (Carnivorans) and Primates (Primates) were the most common. Of the 213 mammal observations counted in the entire study areas, the sightings of Kirk’s Dik-dik (Madoqua kirkii) were the most abundant followed by Yellow Baboon (Papio cynocephalus). Three groups of Reticulated Giraffe (Giraffa camelopardalis reticulata) cumulatively of 35 animals, were observed in between Garissa to Bulanandir-Kora Kora. The rangeland in the study areas (Bangal, Garissa, Bura and Hola) was devoid of large and medium sized mammals, probably because of illegal bush-meat hunting, highly degraded habitats by livestock overgrazing and continuous invasion by the exotic Prosopsis juliflora bushes. An additional, 288 records of stuffed skins/skulls were retrieved and digitized from specimens collected and preserved at the Mammalogy Section lab, National Museums of Kenya (NMK). These specimens were mainly of small mammals (rodents, shrews and bats) collected in different localities within the entire Tana River Basin (TRB) ecosystem in between 1903-2015. The most dominant were individuals of the Order Rodentia (210), followed by Soricomorpha (white-toothed Shrews (22) and Order Chiroptera (bats (21). This information underscores the importance of the entire TRB ecosystem for the conservation of mammal biodiversity in Kenya.

| Descrição da Área de Estudo | Tana River Basin is located in south eastern Kenya approximately between latitudes 0°0’53” and 2°0’41’’ South, and longitudes 38°25’43” and 40°15’ East, covering an area of about 95,000 km2 (Baker et al 2015). It is bordered by the Ewaso Ng’iro North Catchment to the north, the Rift Valley to the west, Athi Basin to the south and Somalia and the Indian Ocean to the east. The Tana River has its headwaters in the forests of Mount Kenya and the Nyandarua Ranges including Aberdares and rapidly descends down the mountain slopes where there is intensive agriculture, then through the arid and semi-arid areas comprising rangelands and finally terminates in a large delta at the Indian Ocean. The basin is generally divided into three ecosystems that are recognised based on their elevation, climate and vegetation cover (Van Beukering and De Moel 2015). The upper catchment above 1000 m a.s.l. consists of forested regions with high relief and higher rainfall. The middle catchment between 300-1000 m is flatter, drier and semi-arid to arid. The lower catchment below 300 m a.s.l. is semi-arid to moist at the coast with dry coastal forests and mangroves swamps and forms a delta with a large floodplain before discharging into the Indian Ocean. |
| Descrição do Design | The occurrence records were compiled from a short field visits to the mid TRB (Bangal, Garissa, Bura and Hola) in between 1st to 7th November 2019. The middle section (Hola, Bura and Garissa) of TRB ecosystem where the fieldwork was undertaken, is characterised by a dryland/rangeland vegetation dominated by Acacia-Commiphora bushlands. Transects were identified in various places around Hola, Bura, Garissa and Bangal, and searched for individuals of mammals as well as their signs (predominantly tracks, but also faeces, carcasses or body parts, digging or burrows 1) Melo et al. 2012; Roberts 2011). Local people encountered at the transect sites or our community guides, were also interviewed about the presence or absence of large and medium sized mammals, by being shown photos of mammals in Kingdon’s (2015) African mammal guide and asked to confirm or deny the presence of these species in their area (Geleta and Bekele, 2016; Cáceres-Martnez et al. 2016; Legese et al. 2019). In addition, specimen records are from vouchers collected using different methods appropriate for each taxon, especially dried stuffed skins deposited in the Mammalogy Section Lab-National Museums of Kenya. |
