Consevaion

Reerences

Because of the limited area and patchy disribu-
ion of the coastal forests, and because of the
sriking individualiy of many of them, all must be
given high priority or consevaion on an intena-
ional level. Most coastal forests include rare spe-
cies (most species of high conservaion priority in
the sample are marked with two or three more ex-
clamaion marks in Appendix 5.1). Some coastal
orests are paricularly rich in rare species. Most
of the remaining forests of these types are
seriously threatened by human aciviies.
1. The Southen Dry orests, especially Pugu
Hills and Pande, include several
endangered species threatened by charcoal
making and other desrucive aciviies.
2. The small remaining patches of limestone
orest in the Northen coastal orests are
seriously threatened by farming.
3. The higher peaks in southen Kenya, e.g.
Mrima Hill, also include several very rare
or endemic species.

The patten described here covers the orests
of only a small part of a chain of the East African
coasts. There is much to be discovered taxonomi-
cally, phytogeographically and ecologically by
more detailed examinaion of these forest com-
muniies, and by eploraion of the lesser known
vegetaion south of the Rufiji River. Even if that
eploraion were complete, however, the
Tanzanian coastal vegetaion south of the Ruiji
River would almost certainly warrant a new chap-
ter in the story of the East African forests.
