Couverture géographique

These data were collected by the Forest Department of Uganda under the ‘Natural Forest Management and Conservation Project’ (No. 6100.37.42.015) and the project of ‘Institutional Support for the Protection of East African Biodiversity’ (UNO/RAF/006/GEF). These data were collected from 1993 to1995 and published in a series of reports edited by Howard and Davenport (1996). The data have been mobilized by the staff of the A Rocha Uganda and A Rocha International under the project "Raising the profile of data for the conservation of four forested African landscapes" funded by GBIF's BID Programme, and coordinated by ARocha Kenya. The mobilized data consists of checklist of trees and shrubs in Mabira Forest Reserve. The data are based on fieldwork which involved a team of botanists surveying the reserve along a series of transects, observing and searching for new species of trees and shrubs between May,1993 and March,1995.

Couverture taxonomique

A total of 310 shrub and tree species were recorded and identified to species level.

Données sur le projet

A Rocha Uganda is part of the eleven organizations that came together to mobilize, share and use biodiversity data across four African countries to help with the conservation of four forested African landscapes. These landscapes cover over 450,000 hectares of tropical forests in four countries where the A Rocha family is undertaking conservation work. The project includes five of the organizations belonging to the A Rocha family (i.e., A Rocha Uganda, A Rocha International, A Rocha Kenya, Eden Care Initiative-Nigeria, and A Rocha Ghana) as partners. Other partner organizations include; National Museum of Kenya, African Butterfly Research Institute (ABRI), Kenya Wildlife Service, National Forest Authority in Uganda, Council for Scientific Industrial Research- Food Research Institute in Ghana and A.P Leventis Ornithological Research Institute in Nigeria. With funding from JRS Biodiversity Foundation and European Union (https://european-union.europa.eu/) through the Biodiversity Information for Development (BID) program of GBIF, a regional project “Raising the profile of data for the conservation of four forested African landscapes” was initiated and its seeking to utilize biodiversity data to better conserve biodiversity-rich but threatened forests of Atewa in Ghana; key coastal forests of Kenya (Dakatcha, Taita Hills, Shimba Hills and Kaya Forests); Kwande and Oban-liku in Nigeria and Eastern Uganda key forests (West Bugwe and Igwe-Luvunya, South Busoga, Bukaleba, Mabira, Mukono, Mpanga, Mpigi and Zika Forest Reserves).

Méthodes d'échantillonnage

Whilst following a transect, the botanists observed broad patterns of species composition, so as to compile a ‘day list’ of the trees and shrubs encountered, together with an evaluation of abundance for each species using the DAFOR acronym (where D = Dominant; A = Abundant; F = Frequent; O = Occasional and R = Rare, see box below). Thus, the field records generated by each day’s fieldwork comprised a map showing the transect route taken, a corresponding list of species encountered and an abundance rating for each species. A broad definition of trees and shrubs has been used so as to include sub-shrubs and climbing/scrambling shrubs, but excluding woody climbers and woody herbs.

Description des étapes de la méthode:

1. The national survey of Uganda forests collected data in 65 forests. The original field survey results including all data were published in a series of reports by the Forest Department of Uganda (Howard et al. 1996). The current dataset comprises records of trees and shrubs transected during this survey. We selected a sample of forests that had been surveyed in the Central and Eastern Regions of Uganda in order to digitize the data for GBIF. Electronic copies of the written reports and a separate electronic database of records were made available for this purpose by the original authors of the reports (Peter Howard). We extracted the records of trees and shrubs from the electronic database and supplemented these with location data provided in the narrative reports. The location data in the original reports were provided in Military Grid Reference System. These were first converted to standard UTM coordinates, noting that the MGRS was using an old datum (MGRS-AL scheme also called "MGRS old"). UTM coordinates were then converted to decimal degrees using an online conversion spreadsheet (https://giscrack.com/download-excel-template-convert-geographic-coordinates-utm/). The converted locations were then checked against Google Maps imagery to confirm that a satisfactory conversion had been made. Species records from each Forest Reserve were checked against the distribution maps in Carswell et al. (2005) and through expert assessment (J. Lindsell & Mary Namaganda) to ensure that no unsubstantiated or extralimital records were included.
