說明
The dataset contains Tana River Basin species occurrence records for amphibians and reptiles digitized from the herpetological collection at the National Museums of Kenya. Label data was transcribed and collection localities were georeferenced using GeoLocate if not provided on the specimen labels. The taxonomy follows nomenclature standards by Channing & Howell (2006) and Spawls et al. (2018). The dataset comprises 58 amphibian species in 23 genera and 15 families which is about 53 percent of all known amphibians species in Kenya. With regard to reptiles, there are 136 species in 67 genera and 16 families which is about 45 percent of all known reptile species in Kenya. Among the interesting taxa are Tana River Basin endemics such as Hyperolius cystocandicans, Boulengerula denhardti, Boulengerula spawlsi, Schistometopum gregori, Atheris desaixi, Kinyongia excubitor, Trioceros schubotzi, Thrasops schmidti, Phrynobatrachus irangi, and the rare taxa such as Phrynobatrachus irangi. Tana River Basin ecosystem is therefore a critical habitat for the conservation of endemic taxa.

| 研究區域描述 | 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 winds from its headwaters in the forests of Mount Kenya and the Nyandarua Ranges including the Aberdares and rapidly descends down the mountain slopes where there is intensive agriculture, then through the arid and semi-arid areas and finally terminates in a large delta at the Indian Ocean. The basin is generally divided into three distinct ecosystems that are recognized 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 with rangelands that support pastoralism. 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. |
