Site description The Ukaguru mountains are a raised plateau that lie in the rain-shadow of the taller Uluguru mountains (TZ068), 40 km to the south-east. The climax vegetation is moist forest, but generally with a lower canopy and less diversity than forest closer to the coast. Elfin forest exists in small patches near the summits and there are large areas of degraded grassland, especially to the west of the main forest block. Important tree species in Mamiwa-Kisara North Forest Reserve include Balthasaria schliebenii, Ocotea usambarensis, Podocarpus latifolius and Polyscias stuhlmannii. Five of seven Forest Reserves listed for these mountains are included in the IBA: Ikwamba (889 ha), Mamboto (149 ha), Mamiwa-Kisara North (7,897 ha), Mamiwa-Kisara South (6,266 ha) and Uponera (293 ha), The remaining two small reserves are now down to exotic pines and are excluded. Immediately to the north-west of these mountains, including the northern and western slopes, is dry Acacia–Commiphora woodland of the Somali–Masai biome. To the west are the Kiboriani mountains, with lower-altitude moist forest that has not been explored recently. To the south-west, separated by the Gombo Mkondoa river valley, are the Rubeho mountains (TZ064) while to the north-east lie the Nguru mountains (TZ059). Between these mountains are important stands of miombo woodland. The eastern slopes of the Ukaguru mountains slope rather rapidly into coastal lowland flood-plain.
