Occurrence records of mammal species in Tana River Basin, Kenya

Latest version published by National Museums of Kenya on Sep 4, 2019 National Museums of Kenya

The dataset represents occurrence records for mammal species in the Tana River Basin (TRB) ecosystem as well as a few outliers from the Aberdare National Park. The data were mainly sourced from published literature and the accessions register of mammal collections maintained by the Mammalogy Section, National Museums of Kenya (NMK). A few additional records were gleaned from unpublished grey literature as well as sightings and reports by ecotourism websites and lodges operating in TRB. Existing records were supplemented by fieldwork in selected areas to help in ground-truthing and filling data gaps. A total of 935 occurrence records represented by 16 orders, 46 families, 124 genera and 183 mammal species are presented here. Sites frequently visited in the past including Mt. Kenya and Meru National Parks had the largest number of mammal observations, while less visited sites such as Mumoni Hill Forest had very few records. The TRB is important for the protection of nine mammals endemic to Kenya including Cercocebus galeritus (Tana River Mangabey), Tachyoryctes rex (King Root-rat), Tachyoryctes spalacinus (Embi African Root-rat), Grammomys gigas (Giant Thicket Rat), Hylomyscus endorobae (Endorobo Wood Mouse), Otomys orestes (Afroalpine Vlei Rat), Crocidura fumosa (Smoky White-toothed Shrew), Surdisorex norae (Aberdare Mole-shrew) and Surdisorex polulus (Mount Kenya Mole-shrew). The ecosystem is also important for the conservation of three endemic mammal sub-species: Colobus guerza kikuyuensis (Mount Kenya Guereza), Cercopithecus mitis albotorquatus (Pousargues’s Monkey) and Perodicticus potto stockleyi (Mount Kenya Potto). Other species of conservation concern found in TRB are two Critically Endangered (CR) species namely, Beatragus hunteri (Hirola) and Diceros bicornis (Black Rhinoceros) as well seven endangered (EN) mammal species (Procolobus rufomitratus (Eastern Red Colobus), Cercocebus galeritus (Tana River Mangabey), Lycaon pictus (African Wild Dog), Equus grevyi (Grévy’s Zebra), Redunca fulvorufula (Mountain Reedbuck), Oryx beisa (Beisa Oryx) and Grammomys gigas (Giant Thicket Rat). This information underscores the importance of the entire TRB ecosystem for the conservation of mammal biodiversity.

Data Records

Title Developing a Freshwater Biodiversity Information System for the Tana River Basin, Kenya, for Improved Ecosystem Management and Development Planning
Identifier 60704 JRS-NMK
Funding JRS Biodiversity Foundation - https://jrsbiodiversity.org/
Study Area Description 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.
Design Description The occurrence records were compiled from the register of specimens collections at the Mammalogy Section, NMK, published literature and selected websites of tour operators and lodges operating in the TRB. Circumstantial evidence through interviews with the local people also yielded some occurrence records. The key literature sources were: Neal (1984), Alibhai and Keys (1985), Cunningham-van Somren (1986), Butynski and Mwangi (1994), Braude et al. (2000), Lambrechts et al. (2003), Webala et al. (2004), Njoroge et al. (2006), KFS (2010) Lala (2011), Dowsett-Lemaire and Dowsett. 2014; Demos et al. (2018), Hall (2018); Musila et al. (2018); Musila et al. (2019). Specimen records are from vouchers collected using different methods appropriate for each taxon, including dried skins and material preserved in 70% ethanol, and deposited in the Mammalogy Section Lab. In addition, a short field work was conducted in May 2019, to selected areas in upper TRB covering Ngaya, Chuka (Kiang’ondu), Kijegge and Kiang’ombe. Field observations of mammals were also carried out using different methods appropriate for each order, family or species. For taxonomy and common names of mammals we follow Kingdon (2015).
