Annex 2. Profiles
of Tree Species: Africa 33 Brachylaena
huillensis Synonym: Brachylaena
hutchisonii Muhuhu
Distribution This
species occurs in Angola, Kenya, Mozambique, Tanzania, Transvaal and Uganda.
Habitat In
Kenya, B.
huillensis occurs in the highlands, the coastal
belt and in forest remnants (WCMC, 1991). It is found
in upland semi-deciduous forest and lowland dry forest or thicket (Beentje, 1994).
It is found in the Usambara steppe and coastal lowland of Tanzania
and Uganda (WCMC, 1991). This species is dominant in
evergreen bush, is common in dry coastal forests and can be found in lowland
dry forests and semi-deciduous dry upland forests (1500m-2000m)
(FAO, 1986). Population Status and
Trends The distribution of this species is patchy
(Marshall & Jenkins, 1994). B.
huillensis is
locally common
in Kenya
(Beentje, 1994).
Role of Species in its Ecosystem
Threats The
species is subject to heavy exploitation in Tanzania. In Kenya, much of the habitat
of this species has been lost and the remaining trees
are subject to increasingly heavy felling (WCMC, 1991). It is also suffering
from habitat loss due to settlement and cultivation (FAO, 1986) Utilisation
This species has been used for sleepers, flooring blocks, furniture,
carving and turnery. Its main use internationally is
now for wood carvings. It is commonly used in Tanzania for building posts. In
Kenya, this species is only used in the carving industry and
not for sawn wood (Marshall & Jenkins, 1994).
Perfumed oil can be distilled from the wood (FAO, 1986).
Trade Conservation
Status This species is considered Rare in Uganda
(Katende, 1995). Conservation Measures
It is considered a priority for in
situ conservation by FAO, 1984. B.
huillensis is
found in
the Arabuko-Sokoke
Forest Reserve
and the
Shimba Hills
Forest Reserve
of Kenya. However
in both of these areas this species is being collected. In the Arabuko-Sokoko
Forest Reserve licences are issued for collection of
dead wood but most of the trees removed are either newly dead
(possibly ring-barked trees) or illegally cut trees (Marshall & Jenkins, 1994).
It is also collected in the Lamu district and transported
to Mombasa for the carving industry (Marshall & Jenkins, 1994). There
are 69 ha of this species in plantations in Kenya (Marshall & Jenkins, 1994).
