Summary of biological values for forest areas of conservation significance
Note that further details of many of these sites are given
in the reviews by Lucas (1968), Beentje
(l
990a) and
Polhill (1988) for Kenya; and Polhill (1968, 1988) and
Lovett (1985, 1990) for Tanzania. Details of areas
gazetted as National Park or National Reserve are given
in IUCN, 1987.
3.
Pande Forest (now Game) Reserve, Coast
Region. <10 km
2
good forest. Distinctive botanically,
several very local endemics, including many Annona-
ceae. Diverse avifauna, relict small bovid fauna. Poorly
described (see Hawthorne, 1984; Collar
&
Stuart,
1985).
4.
Kiono, Kazimzumbwie, Zaraninge Forest
Reserves, Coast Region. Key examples of fragmented
patches of coastal forests. Hawthorne, 1984; Burgess
et
al.,
1990.
5.
Rufiji River Delta, FRs, Coast Region. Mainly
mangroves (Forest Dept. 1990), 100 km
2
• Area long
considered as a Biosphere Reserve and marine park.
6.
Kichi Hills, Coast Region. NO STATUS. Exten-
sive areas of dry closed forest and evergreen thicket.
Several endemic plants (e.g.
Pteleopsis :
Vollesen, 1980).
Nearby Matumbi Hills, Coast-Lindi Region, have
deep moist ravines; recent eploration found
Saint-
paulia .fican violet)
populaions, and many new and
significant bird species records. Burgess
et al.,
1990.
7. Lindi Area (Baobab forest, Lake Lutamba),
Lindi Region. NO STATUS. Lake Lutamba is the
type locality for many endemic rare plants. Polhill,
1968.
8. Rondo Plateau FR, Lindi Region. < 10 km
2
natural forest. Poorly described: see Burgess
et al.
(1990) for recent reconnaissance.
Milicia, Khaya
com-
munities, important 'stepping-stone' site for lowland
forest bird distributions.
9. Magombero FR (remaining intact areas now in
Selous Game Reseve), Morogoro Region. 9 km
2
•
Groundwater forest, 300 m a.s.l.
Milicia, Khaya
(greatly
disturbed by past logging),
Eythrophleum, ls oberlinia
schfleri,
many endemics (tree, shrub and herb).
Avifaunal links to adjacent Mwanihana Forest in
Uzungwa Mts. Rodgers
et al.,
1979; Vollesen, 1980.
10. Kimboza FR, Morogoro Region. 4 km
2
• Relict
patch on limestone karst, exceptionally rich botanically,
Parkia, Milicia, Antiaris, Scorodphleus, Sorindeia, Elaeis,
Pananus.
17 plant endemics, e.g.
Cy nometra,
and
Lepidoptera and a lizard. Plants, birds and butterflies
well documented (Rodgers
et al,
1983). Under localised
pressure for fuel and poles (Hall
&
Rodgers, 1986).
Nearby Ruvu FR is similar but drier, and needs
survey.
11.Kitulanghalo, Dindili, Pongwe FRs, Morogoro
and Coast Regions. 25 km
2
. Isolated hills, with dry
closed forest, e.g.
Scorodophleus, Manilkara,
etc. and
locally,
Brachylaena.
Urgent need for more survey.
Coastal and lowland communiies
A) Islands
1.Jozani Forest, Zanzibar. FR, and potential Nation-
al Park. 26 km
2
• Swamp forest
(Calophyllum,Anthocleis-
ta, Bridelia, Elias, Pandanus,
etc.), surrounded by forest
and thicket communiies on coral rag
(Manilkara,
Mimusps, Teminalia,
Annonaceae, Celastraceae, etc.).
Major habitat for endemic red colobus monkey, plus 3
endemic bovid subspecies. Struhsaker
&
Leland, 1980;
Sruhsaker, 1991; Mturi, 1991.
2.
Ngezi Forest, Pemba. FR, and potential NP. 14
km
2
• Diverse forest communities from almost pure
Antiais, Odyenea
stands to 40 m height through
Uapaca, Syzygium, Pachystela
mixed forest to swamp
forest of
Barintonia
and
Samadea indica
(the only
African locality), to mangrove. Many exceptional dis-
tribuional and altitudinal records, e.g.
Polysias;
and
linkages to Madagascar. Three Pemba endemic plants.
Poorly explored. Rodgers
et al.,
1986; Beentje
l
990a.
3.
Coral Rag Forests, Mafia. NO STATUS. Mixture
oflowland evergreen forest and coral rag thicket. Better
forest already cleared for agriculture. Still extensive
mangrove. Need for survey and choice of areas
important for consevation interests. Rodgers
et al.,
1988.
B)
Mainland, Ta nzania
1.
Kisiju Forest, Coast Region. NO STATUS. <3
km
2
• Dry lowland evergreen forest, dominated by
Hy menaea
(gum copal), merging into
Baringtonia
and
mangrove communities. Rapidly being converted for
cultivation. Important as example of once widespread
forest type of historical commercial value. Rodgers
et
al.,
1983; Hawthone, 1984; Burgess
et al.,
1990.
2.
Pugu Forest Reseve, Coast Region. <4 km
2
good forest. Biologically well known (e.g. Howell, 1981;
Hawthone, 1984). Important coast bird locality (Collar
&
Stuart, 1985), many plant endemics (e.g.
Baphia,
Millettia) .
Urgent need of improved protection from
mining, plantation development, encroachment, and
illegal fuel and pole collection. Growing support from
Tanzania Wildlife Consevation Society.
