The term savanna, also savannah, refers to a form of flora that thrives in hot, seasonally dry climates and is distinguished by an open tree canopy (i.e., dispersed trees) over a continuous understory of tall grass (the vegetation layer that lies between

Angola is botanically rich and floristically diverse, but is still very unevenly explored with very few collections from the eastern half of the country. We present an overview of historical and current botanical activity in Angola, and point to some areas of future research. Approximately 6850 sp...

Microclimatic and edaphic conditions in the subcanopy habitat under trees and shrubs often differ widely from those in the grassland. The subcanopy is unstable and subject to much disturbance, mainly due to its rich and varied fauna. A total of 132 plant species was recorded as typical for, ...

Savanna - Flora, Fauna, Ecology: Savanna plants annually experience a long period in which moisture is inadequate for continued growth. Although the aboveground parts of the shallow-rooted grasses quickly dry out and die, the more deeply rooted trees can

This history explains, for example, the close similarities between the fauna and flora of high mountains such as the European Alps and the Arctic...
Africa - Flora, Fauna, Ecosystems: African vegetation develops in direct response to the interacting effects of rainfall, temperature, topography, and type of soil; it is further modified by the incidence of fire, human agriculture, and grazing and brows
Veld, name given to various types of open country in Southern Africa that is used for pasturage and farmland. To most South African farmers today the “veld” refers to the land they work, much of which has long since ceased to be “natural.” Various ty
