30 Baillonella toxisperma
Moabi Distribution
Moabi occurs mainly in Cameroon, Gabon and Nigeria, and is also
found in Angola, Congo and Equatorial Guinea.
Habitat The
monotypic genus Baillonella is endemic to the Guineo-Congolian
region (White, 1983). B. toxisperma
is limited
to dense
primary evergreen
rain forests.
It requires
shade for
regeneration to
occur (Wilks in
litt, 1990). Population
Status and Trends If this species continues to
be over-exploited it will most likely vanish from large areas of its distribution
(Schneemann, 1995). In areas of Cameroon that have been logged for several decades
(i.e. Central, South, South-West and the Littoral provinces)
there is a decrease and in some cases disappearance
of Moabi (Schneemann, 1995). Moabi still remains in East Cameroon where there
has been no logging. Role
of Species in its Ecosystem Elephants play a
part in regeneration and dispersal of Moabi as they eat the fruits and deposit
the seeds elsewhere (Schneemann, 1995). Wild pigs and
porcupines eat the seeds. Threats
Moabi is heavily exploited in West Africa. This species is
further threatened by its restricted regeneration (Wilks
in litt.,
1990). It takes between 50 and 70 years before B.toxisperma
starts to flower and regular fruit production doesn't
occur until the tree is 90-100 years old (Schneemann, 1995). Utilisation
The timber is used for furniture, cabinet work, decorative
flooring, turnery and carving, decorative veneers, joinery,
and stove fittings. The edible oil (huile de karité)
that is extracted from the seeds is of great importance to the local people.
The oil can fetch high prices at the local markets in Cameroon; in the larger
cities the oil can be worth as much as US$12/litre (Schneemann,
1995). The pulp of the fruit is eaten. The bark is used for medicinal
purposes and has ethnobotanical uses (e.g. the Baka pygmies use the bark to become
invisible for elephant hunting) (Schneemann, 1995).
Trade Strong
demand for Moabi timber comes from Southern Europe (Schneemann, 1995) Moabi
is an important commercial timber in Cameroon and is a major species in the export
trade. Production of B.
toxisperma in Cameroon has almost doubled since
1989/1990 (Schneemann, 1995). It is also commercially
important to Congo (exports in 1988 of 4,517m3)
and Gabon where it is the second most important wood
in terms of export earnings (Wilks in
litt, 1990). Gabon exported 55,884m3
in 1987 (IUCN, 1990) and 59,891m3 in 1989.
According to ITTO (1995a) 25,000 m3
of B. toxisperma
logs were exported from Cameroon in 1994 at an average
price of US$385/m3, and 10,000 m3
of sawn timber were also exported at an average price of
US$700.00/m3. While Gabon exported Moabi logs
at an average price of US$70.40/m3 and exported
82m3 of sawnwood at US$63.13/m3
(ITTO, 1995a). In 1994, Gabon exported a total of 32,572.065 m3
of Moabi and 44,390.331 m3
in 1995 (DIAF, 1996). There is some concern about illegal
trade from some of the Moabi producing countries (Draft CITES Proposal,
1991). Conservation Status
IUCN Category and Criteria: VU (A1d) (African Regional Workshop,
1996) Conservation Measures
The minimum exploitable diameter of Moabi in Cameroon is 1m
and in both Gabon and Congo the minimum exploitable
diameter is decreed to be 0.8m. B.toxisperma
is found in several protected areas in Cameroon (i.e.
Forêt de Nki, Forêt de Boumba Bek and Reserve de Faune du Dja). This
species is also represented in the Sibang Arboretum,
Libreville, Gabon. (Draft CITES Proposal, 1991). Cameroon has
planted 389 ha of this species (African Regional Workshop, 1996). References
