Plant species occurrences recorded from selected sites in the upper Tana River Basin, Kenya

Latest version published by National Museums of Kenya on Sep 10, 2019 National Museums of Kenya

The dataset contains plant species occurrences recorded during fieldwork carried out from 2018 to 2019 in selected sites in Nyeri, Meru, Embu, Murang’a, Tharaka Nithi and Kiambu Counties all in the Upper Tana River Basin, Kenya. The sites included: Kiang’ondu Forest; Ngaya Forest; Kijegge Hill; Kathithini, Kamanyathi Location; Nkorongo River, Mwonyonzi, Chiakariga Location; Kiang’ombe Hill; Thegu, Gura, Sagana, Mathioya, Maragua, Channia, Chania and Thika Rivers; Gathabara, Mbuguti,and Mitai streams as well as Kimakia Forest in the Aberdares. The plants species were mainly identified on site to species level and documented as site records. However, in a few cases, voucher specimens were collected for confirmation and preservation at the East African Herbarium (EA), National Museums of Kenya, Nairobi. Geo-references were taken on site using a Garmin GPSMAP64s.

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

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 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 rangelands 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. There is intensive agriculture in most parts of the upper Catchment. 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.
Design Description Line transects and opportunistic sampling was used in surveying..

Sampling Methods

Line transects and opportunistic collections

Study Extent The dataset was recorded between May 7th to July 2nd 2019.
Quality Control Species identification was done on site by a team of scientists and technicians from the East African Herbarium. For difficult or interesting taxa (rare, endemic, underrepresented in the herbarium), voucher specimens were collected for confirmation and for permanent preservation at the East African Herbarium (EA).

Method step description:

  1. Different habitats types were identified, including forests, wetlands, bushlands and riverine areas. Sampling for occurrences was carried out along straight line transects Opportunistic sampling was also carried out to try and document the complete diversity of the plants in a given site. All georeferences were taken in the field with a Garmin GPSMAP64s recorder and locality descriptions described with the help of local people on site.
