The national park is the only one in Zambia covered by forest, categorised in the small Cryptosepalum dry forests ecoregion, which exists only in a few patches in the south west of the province extending a little over the border into Angola. Cryptosepalum trees (called “mukwe” locally) are evergreen and grow densely with a closed canopy. The ecoregion forms the largest evergreen forest in Africa outside of the equatorial zone. Although the rainfall in the area is quite high (above 1,000 mm per year) the soils are sandy and well drained so apart from the rivers there is a lack of surface water.[1] A few patches of Miombo woodland and grassland also exist in the park.
