Upland Acacia wooded grassland (We)

Description

Where domestic (or wild) animals are numerous, East African evergreen bushland (Be) has been severely degraded and invaded by Acacia species. It is therefore typical to find Acacia drepanolobium, Acacia hockii, Acacia kirkii and Acacia seyal occurring together with evergreen species such as Carissa edulis, Dodonaea viscosa, Euclea divinorum, Euclea racemosa and Tarchonanthus camphoratus (White 1983 p. 115). Similarly, Evergreen bushland (Be) communities of the Lake Victoria region have been extensively destroyed and replaced by a lightly wooded Acacia grassland dominated by Acacia hockii, Acacia gerrardii, Acacia kirkii, Acacia senegal and Euphorbia candelabrum (also an emergent of evergreen bushland (Be)).

As several of these Acacia species are also typical of Edaphic wooded grassland on drainage-impeded or seasonally flooded soils (wd), we expect that not all areas that were mapped as Upland Acacia wooded grassland are an “alternative steady state” of Evergreen and semi-evergreen bushland and thicket (Be). As we lacked ancillary information, we do not know which portion of Upland Acacia wooded grassland occurs mainly for edaphic reasons (this is something that we will try to resolve in later versions of the VECEA map). Because of the floristic overlap in Acacia species between Acacia-Commiphora deciduous wooded grassland (Wd) and Upland Acacia wooded grassland, it is also possible that some areas that we mapped as Upland Acacia wooded grassland should have been mapped as Acacia-Commiphora deciduous wooded grassland (Wd) instead.

Plant species

The main species recorded to occur within this vegetation type are listed below. Clicking the name of any of these species will open the page for that species on the Agroforestry Species Switchboard. Between brackets the English vernacular name of the species and the documented country distribution of the species (B=Burundi, E=Ethiopia, K=Kenya, M=Malawi, R=Rwanda, T=Tanzania, U=Uganda, Z=Zambia) is provided.

Based on information on species presence in national manifestations of vegetation types, each species was classified as a regionally dominant, characteristic, present or marginal species for a vegetation type (Read more ...)

Products and environmental services of tree species

Documented products and environmental services for the tree species occurring in this vegetation type (We) are listed below. Clicking the name of any of these species will open the page for that species on the Agroforestry Species Switchboard. Between brackets information is given on the status of each species ('dom' indicates dominant species, 'cha' characteristic species, 'pre' other species and 'mar' species of marginal occurrence), the English vernacular name of the species and the documented country distribution of the species (B=Burundi, E=Ethiopia, K=Kenya, M=Malawi, R=Rwanda, T=Tanzania, U=Uganda, Z=Zambia).

For more detailed information about the species occurrences see this excel workbook. It provides country specific information on species composition for this vegetation type. It also allows you to select a subset of useful tree species to provide desired products and services. For each species links to a number of websites / databases with information about this species are provided as well.

Conservation status

The table shows the area (km2) of the vegetation type and the percentage of this area explicitly designated for biodiversity, species or landscape protection (A) and areas designated for both protection and sustainable use objectives (B). Only the nationally designated protected areas were included.

PNV Area (km2) A (%) B (%)
Be/We 3,855 2.40 0.00
We 19,259 15.60 5.20

A) Include the IUCN categories I - IV; B) Include the IUCN categories V - VI and the protected areas without IUCN classification. Read more
