Site description Dzombo hill, like Mrima (IBA KE018), is an igneous intrusion into the Triassic sandstone of the surrounding coastal plain. The hill rises abruptly to around 470 m, with a lower summit at 400 m to the west. The rainfall is 900–1,100 mm/year, with considerable additional mist and dew on the upper slopes. Dzombo is covered by undifferentiated coastal mixed forest, wettest on the south-eastern slopes. To the north and north-west, the forest grades into drier woodland and scrub. Large trees include Combretum schumannii, Lannea welwitschii, Cola clavata, Ricinodendron heudelotii, Scorodophloeus fischeri, Tamarindus indica, Newtonia paucijuga, Sorindeia madagascariensis, Diospyros mespiliformis and Manilkara discolor. Dzombo was designated as a Forest Reserve in 1941, and Kaya Dzombo as a National Monument, within the Forest Reserve, in 1992. The forest is considered sacred by the local community, with the grave of a Digo ruler, or Kubo, near the summit.
