Kazimzumbwi Forest Reserve

(n = 23). The ratio of trees per plot to species per plot ranges from 16:14 (1.14) to 76:8 (9.50),
demonstrating that species dominance varies greatly between plots. This is thought to be a result
of the high diversity of vegetation types throughout the reserve, for example the data for the first
ratio comes from a vegetation plot situated in Mixed dry Coastal Forest whilst the latter comes
from a plot situated in an old Cassia sp. plantation.
Thirteen species recorded in the vegetation plots (12% of all species) represent new records for
Coastal Forests, i.e. they do not appear in florulas given by Clarke, Vollesen and Mwasumbi
(2000) (a list of plant species endemic to the Swahilian Regional Centre of Endemism sensu lato )
or Clarke (1995) (a checklist of vascular plants from 13 Coastal Forests). All are widespread tree
or shrub species in families already represented in Coastal Forests.
Eleven species recorded in the vegetation plots (10% of all species) are considered forest
dependent species. These include species confined to ‘forest’, Brachystegia Forest and Riverine
Forest, as Burgess and Clarke (2000) present these as major vegetation types within Coastal
Forests.
One species recorded in the vegetation plots (
