on the border is the highest peak in Mozambique and the second-highest in Zimbabwe. Mussapa Gap is a pass through the mountains that follows the eastward-flowing Mussapa Grande River and westward-flowing Nyanyadzi River. Mussapa Gap was an important trade and migration route through the highlands for centuries. The Rusitu-Tanganda fault, an east-west rift that carries the eastward-flowing Rusitu River and the westward flowing Tanganda River, marks the southern end of the Chimanimani Mountains. A hilly upland extends south from the fault into Chipinge District, and the highest point is Mount Selinda at 1230 meters. The Eastern Highlands are part of the East African Highlands, one of four distinct physiographic divisions on the African continent. The East African Highlands physiographic division consists of the East African Rift and Abyssinian physiographic provinces, part of the long chain of mountains that runs down East Africa. The mountains and mountain ranges that make up the East African Highlands share many common plant and animal species and communities, known as Afromontane flora and fauna. Climate The Highlands have a more equable climate than Zimbabwe's central plateau, with higher rainfall, low cloud and heavy mists and dew as moisture moves inland from the Indian Ocean. Many streams and rivers originate in these mountains. The northern portion is drained by tributaries of the Zambezi River, while the southern portion is drained by tributaries of the Save River. The eastern slope is drained by Mozambique's Buzi and Pungwe rivers. Flora Much of the small area consists of rolling hills covered with grassland, which are renewed annually following the fires that occur at the end of the dry season. At lower elevations, Themeda triandra is the predominant grass on the more fertile red soils, and Loudetia simplex is common on less-fertile white sandy soils. At higher elevations are montane grasslands made up mostly of short, tufted grasses, including Loudetia simplex, Trachypogon spicatus, Exotheca abyssinica, and Monocymbium ceresiiforme. Some valleys and east-facing slopes contain areas of subtropical rainforest, with a high canopy, lianas, and a rich undergrowth. There are larger areas of dry forest at higher altitudes in places where the ground is well watered and on drier slopes patches of miombo woodland (Brachystegia spiciformis, Brachystegia tamarindoides and Uapaca kirkiana) and areas of heathland at higher elevations. There are patches of the tall, evergreen mobola plum Parinari curatellifolia near the town of Chipinge and on the western slopes of the
