Status and Trends of Biodiversity Botswana is made up of seven
distinct eco-regions, of which four are vulnerable i.e. South
African Bushveld (deforestation, overgrazing, range degradation
and veldt fires), Zambezia Baikiaea Woodlands (cattle and
overgrazing and change in vegetation communities), Zambezia
Halophytics (mining, rangeland degradation, fires, wind erosion,
fires, water extraction, fencing, increased salinity of surface
water, decreased surface fresh water, overgrazing, lack of
protection for critical avian breeding sites, uncontrolled
tourism/ disturbance and wildlife conflicts) and Kalahari Acacia
(increased cattle ranching, land transformation and degradation,
fires, fences, climate change, poaching and invasive alien
species). The status of the rest of the ecoregions is stable and
intact. Although there has never been a comprehensive survey of
plants in Botswana it is estimated that there are between 2,150
and 3,000 species of plants, of which 15 are endemic and 43 are
Red Data species. Botswa
