La végétation des inselbergs de Piedra Nzas (Guinée Équatoriale continentale)

We report results from a phytosociological investigation of the vegetation of three inselbergs from continental Equatorial Guinea. Ten vegetation units belonging to five plant formations are described: grass-land, herbaceous fringe, shrubby fringe, forest fringe and saxicolous forest. One of the most striking plant communities on inselbergs are species-poor grassland on shallow soil, which comprise several species restricted to inselbergs. Forest fringes and the saxicolous forest have a high species diversity. Soil pH is strikingly low (pH 3,5-4,8). In the saxicolous forest, at 745 m altitude, a Podocarpus latifolius was found. This species usually lives at higher elevations (≥ 1500 m).SCOPUS: ar.j
