Useful Tree Species for Eastern Africa
a species selection tool based on the VECEA Map
Acacia tortilis woodland and wooded grassland
Description
The Range Management Handbook of Kenya (RMHK; Schwartz et al. 1991; Shaabani et al. 1992abc; Herlocker et al. 1993, Herlocker et al. 1994abcd) describes a number of vegetation types that are characterized by Acacia tortilis as (one of) the characteristic Acacia species. These include: (i) Acacia tortilis - Balanites evergreen and semi-deciduous woodland; (ii) Acacia tortilis semi-deciduous woodland (iii) Forbs - Acacia tortilis - Terminalia semi-deciduous wooded grass- land (iv) Acacia tortilis deciduous woodland, (v) Acacia tortilis - Cadaba deciduous woodland, (vi) Sporobolus - Duosperma - Acacia tortilis deciduous wooded grassland, (vii) Chloris - Aristida - Acacia tortilis deciduous wooded annual grassland and (viii) Aristida - Indigofera - Acacia tortilis deciduous wooded annual grass- land.
Note that since Acacia tortilis also occurs in biotic Acacia wooded grassland (We), it is possible that some of these vegetation types should have been mapped as biotic Acacia wooded grassland instead (we did not reclassify as species composition corresponded better with Somalia- Masai Acacia -Commiphora deciduous bushland).
Useful woody 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.
- Characteristic species: Acacia mellifera, Acacia nilotica, Acacia reficiens, Acacia tortilis, Salvadora persica
- Other species present: Acacia oerfota, Acacia senegal, Albizia amara, Balanites aegyptiaca, Croton dichogamus, Terminalia brownii
Conservation status
The table shows the area (km2) of the PNV is outside the protected areas (NP) and the area protected within one of the protected areas, split by IUCN management category. Only the nationally designated protected areas were included.
