        Genus: Afrocarpus mannii
        Family: Podocarpaceae
        Red List: VU D2
        Notes: A montane species endemic, occurring in rainforest above 1300m to the summit of the Pico. There is little threat to the habitat, although there was extensive deforestation earlier in the century up to 1500m.

        Genus: Anisophyllea cabole
        Family: Anisophylleaceae
        Red List: VU D2
        Notes: A tree or shrub, known from two sites towards the north-west of the island at altitudes of 1350 to 1410m. Populations appear to be healthy and regenerating. The species produces a good wood which has moderate value as a timber.

        Genus: Balthasaria mannii
        Family: Theaceae
        Red List: VU D2
        Notes: Endemic to Sâo Tomé, this species occurs in rainforests from 1300m to the summit of Pico. There are no significant threats, although the forest below 1500m was largely cleared at the beginning of the century. The genus is represented elsewhere only by an East African Afromontane species of restricted range.

        Genus: Craterispermum montanum
        Family: Rubiaceae
        Red List: VU B1+2c, D2
        Notes: A small tree, which was relatively well collected on expeditions at the turn of the century and before. In the present day it appears to be localised to a number of primary forest sites at high altitudes (>1000m). The bark is an important ingredient in a fortifying drink for swordfish hunters and also in an aphrodisiac drink. There is evidence that some trees are dying from overcollection of the bark.

        Genus: Croton stellulifer
        Family: Euphorbiaceae
        Red List: VU B1+2c, D2
        Notes: An upland tree with a relatively wide altitudinal range, principally occurring in secondary forest. Populations are recorded from Oquê Pipi on Principe and Lagoa Amelia, Morro Miguel Angelo and Esperanca on Sâo Tomé. Although trees have been seen to set fruit, no regeneration is evident. The wood is valued as a timber. Areas on both islands remain to be inventoried and it is hoped there are regenerating populations in existence.

        Red List: VU D2
        Notes: A forest tree, known only from a few herbarium specimens and thought to be extinct until it was rediscovered in 1968. Populations have been located at a range of altitudes in Pico, Angolares and Monte Café in two locations, one in Esperanca. The remaining populations are now confined to higher altitudes which have evaded deforestation.

        Genus: Irvingia gabonensis
        Family: Irvingiaceae
        Red List: LR/nt
        Notes: Tropical evergreen rainforest is the optimal habitat for this species. However, it occurs also in gallery forest and semi-deciduous forest and is often found in towns or on the outskirts of villages. It is restricted to fairly wet, well-drained loamy to clayey soils. Population numbers have declined through logging operations, the expansion of human settlements and poor natural regeneration.

        Notes: The bulk of the population is found in areas of moist evergreen forest on the eastern mountains of Tanzania. Another population, which shows some morphological distinctness and was originally published under the name of M. henriquesii, occurs on the island of Sâo Tomé. The population here is small and found in areas which were forest at the turn of the century but are now cultivated or secondary forest. The genus is monospecific.

        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.

        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.

        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.
