Equatorial Guinea
| Genus: | Aucoumea klaineana |
| Family: | Burseraceae |
| Red List: | VU A1cd |
| Notes: | Okoumé occurs abundantly in an area covering west and central Gabon and small areas of neighbouring countries. It continues to be Gabon's most important commercial timber. Repeated felling has led to the deterioration of the gene pool in certain areas. There is some concern as to the long-term status of the species. |

| Genus: | Calpocalyx heitzii |
| Family: | Leguminosae |
| Red List: | VU A1c, B1+2c |
| Notes: | Relatively restricted in range, this coastal forest species occurs in the south of Cameroon on the border with Equatorial Guinea and north of the Ogooué River in Gabon. Both populations are threatened because of the extent of felling and degradation of the habitat. |

| Genus: | Casearia barteri |
| Family: | Flacourtiaceae |
| Red List: | LR/lc |
| Notes: | Although the species has been regarded as endemic to countries in the West, where it is uncommon and has suffered habitat losses, the concept of the species published in Flore du Gabon 1995 suggests that the species in broader in range and ecology, occurring in various forest and savanna types from Sierra Leone to Angola and Sudan. |

| Genus: | Crotonogyne manniana |
| Family: | Euphorbiaceae |
| Red List: | LR/nt |
| Notes: | An understorey shrubby tree restricted to but locally abundant in wet evergreen forest. The species is relatively wide-ranging from Ghana to Gabon. Mining, logging and other forestry activities, particularly in Ghana, Nigeria and Cameroon, have caused the general decline and degradation of these forests. |

| Genus: | Daniellia oblonga |
| Family: | Leguminosae |
| Red List: | VU A1c |
| Notes: | A large tree from Atlantic forest. Populations have been recorded in Benin, on the Nigerian border at Oueme, in Ikom in Nigeria, extending into Cameroon and Bioko. Although information on the extent of the species range and its status is incomplete, the habitat is known to have declined severely. |

| Genus: | Entandrophragma angolense |
| Family: | Meliaceae |
| Red List: | VU A1cd |
| Notes: | One of the main sources of African mahogany. The commercial exploitation of this timber species has resulted in the large-scale extraction of mature individuals throughout its range. Significant genetic erosion has been reported in some countries. It has the potential to occur commonly and regenerates well after logging damage but not after burning. The seed does not appear to disperse over great distances and regeneration is poor away from parent trees. A slow-growing species. There are protected populations and felling limits in various countries. |

| Genus: | Eribroma oblonga |
| Family: | Sterculiaceae |

| Genus: | Gossweilerodendron balsamiferum |
| Family: | Leguminosae |
| Red List: | EN A1cd |
| Notes: | Endemic to the Guineo-Congolian region, this timber species is declining in population numbers because of heavy exploitation and habitat loss. It grows in mature little-disturbed lowland rainforest. In the main Zaire/Nigeria forest block it is generally rare or absent. |

| Red List: | VU A1c |
| Notes: | A gregarious forest species restricted to swampy areas, rivers and also coastal regions. Regeneration is good in wet areas. It is able to reproduce vegetatively. Overexploitation of the general-purpose timber and habitat degradation in large parts of its range are causing population declines. |

| Red List: | VU A1cd |
| Notes: | Azobé is a pioneer species and occurs abundantly in wet evergreen forest, which continues to experience large-scale destruction. Slow growth rate, poor regeneration in less than optimum conditions and over exploitation as a timber species are contributing to the decline in population numbers through most of its range. |

| Genus: | Milicia excelsa |
| Family: | Moraceae |
| Red List: | LR/nt |
| Notes: | Iroko, although common and widely distributed in different forest types throughout tropical Africa, suffers from heavy exploitation. East Africa was once a major source of the timber, which was used as a teak substitute until supplies became short. West Africa continues to export large quantities of it. Some populations suffer from gall attacks, especially in plantations, and its seed loses viability quickly. Trees are often left standing after land clearance and natural regeneration is good in open places. |

| Genus: | Prunus africana |
| Family: | Rosaceae |
| Red List: | VU A1cd |
| Notes: | Also commonly known under the name Pygeum africanum, this species is widespread from the African tropics to Madagascar and South Africa. Throughout much of its range, most notably Cameroon and Madagascar, the unsustainable exploitation of its bark and to a lesser degree its timber have caused rapid population declines. It is too rare in some countries to be of commercial use and is most commonly exploited for the local market. An important element in the ecosystem, it is reported to regenerate well. It is listed in *CITES Appendix II and protected in various protected areas. |

| Genus: | Pseudagrostistachys africana |
| Family: | Euphorbiaceae |
| Red List: | VU A1c, B1+2c |
| Notes: | A species which is found mainly in montane forest in the Lower Guinea region. In Nigeria it occurs only on the Obudu Plateau, where fires and encroaching agriculture are causing damage to the restricted areas of remaining vegetation in forested valleys. An anomalous occurrence is known in Ghana, where it is highly localised but common in evergreen rainforest along a river bank. General threats from mining, logging and commercial forestry can affect these areas. This is the only species in the genus. |

| Red List: | EN A1cd |
| Notes: | Although widespread in closed forests in West and Central Africa, the species is not common. It is exploited at a moderate level as a decorative timber. There is also evidence that regeneration may be hampered in places by the absence of its seed disperser, the elephant. |

| Genus: | Triplochiton scleroxylon |
| Family: | Sterculiaceae |
| Red List: | LR/lc |
| Notes: | Obeche occurs in abundance in transitional forest formations. Its range is extending because of its successful colonisation of logged and abandoned farm land. Exploitation of the wood is very heavy and, in places, unsustainable, both for local use and the international timber trade. Of all West Africa timbers this species is extracted at the highest volumes. |

| Family: | Meliaceae |
| Red List: | VU A1cd |
| Notes: | A monotypic genus endemic to the Guineo-Congolian regional centre of endemism. Known as avodiré, the species is commonly found in moist semi-deciduous forest, often in poorly drained places. It is exploited at moderate levels for its timber and is becoming rare in places. Regeneration appears to be sufficient and the tree is sometimes planted on farmland. |
