Savanna
A savanna, or savannah, is a grassland ecosystem characterized by the trees being sufficiently small or widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of C4 grasses.Some...
ecoregions (listed below) characterized by the predominant presence of Miombo species, with a range of climates from humid to semi-arid, and tropical to subtropical or even temperate.
Characteristically the trees shed their leaves for a short period in the dry season to reduce water loss, and produce a flush of new leaves just before the onset of the rainy season with rich gold and red colours masking the underlying chlorophyll, reminiscent of temperate autumn colours.

People
These miombo woodlands are also important to the livelihoods of many rural people, who depend on the resources available from the woodland. The wide variety of species provides non-timber products such as fruits, honey, fodder for livestock and fuelwood.Flora and fauna
Despite the relatively nutrient-poor soil, long dry season (and low rainfall in some areas) the woodland is home to many species, including several miombo specialist endemic bird species. The predominant tree is miombo (BrachystegiaBrachystegia
