Evergreen and semi-evergreen bushland and thicket

Description

Evergreen and semi-evergreen bushland and thicket occurs on the drier slopes of mountains and upland areas in East Africa which rise from the lowlands from the Somalia-Masai region all the way from central Tanzania to Eritrea (and beyond). It often forms an ecotone between Afromontane forest (especially Afromontane single-dominant Juniperus procera forest ( Fbj ) and deciduous bushland ( Bd )) - this pattern of occurrence can be clearly observed in northern Kenya such as at on the lower slopes of Mt. Marsabit (2º 16’ N, 37º 57’ E). The mean annual rainfall is mostly between 500 and 850 mm and is irregularly distributed throughout the year but with two main peaks (White 1983 pp. 48 and 115). Evergreen bushland (in mosaic with Lake Victoria Euphorbia dawei scrub forest ( xfe ) that is edaphically restricted to rocky slopes) probably represents the climax vegetation of large parts of the Lake Victoria region. This evergreen bushland variant is floristically similar but also floristically poorer than the vegetation type with the same name that occurs in the Somalia-Masai region.

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.

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 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. It should be noted that the vegetation type may form only a small part of the listed compound types. For example, Be only occurs at the margins of the Fb/Be/wd compound vegetation type.
