Lake Victoria Strychnos potatorum scrub forest (Ft)

Description

Scrub forests are intermediate in structure between forest and bushland. Vegetation types intermediate between rain forest and evergreen bushland (Be) probably occurred more extensively in the Lake Victoria basin than in other parts of Africa, but only few relicts remain (White 1983 p. 182).

White (1983 p. 182) describes the following types of Lake Victoria scrub forests: (i) Cynometra-Euphorbia scrub forest in Burundi and Uganda; (ii) Euphorbia dawei scrub forest in the basin of Lake Edward; (iii) Euphorbia dawei scrub forest in the Ruzizi valley; and (iv) tall scrub forest in the Ruzizi valley (White 1983 p. 182).

It is the fourth subtype that is mapped in Burundi as Lake Victoria Strychnos potatorum scrub forest (Ft). This forest formation is described as the ‘forêt sclérophylle à Strychnos potatorum’ by Lewalle (1972), who fully agrees with the observation of Germain (1952) that this forest type is the climax vegetation of the Ruzizi valley, except where specific edaphic conditions lead to the manifestation of other vegetation types such as Lake Victoria Euphorbia dawei scrub forest (fe) or Palm wooded grassland (P).

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 (Ft) 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).
