Lake Victoria Euphorbia dawei scrub forest
Lake Victoria Euphorbia dawei scrub forest
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 third subtype that is mapped in Burundi as Lake Victoria Euphorbia dawei forest (fe). We classified Euphorbia dawei scrub forest as an edaphic vegetation type based on the suggestion that this vegetation type is especially restricted to rocky slopes, whereas evergreen bushland (Be) would be the climax vegetation type elsewhere (White 1983 p. 183)
