The vegetation of the park (Cassells, 1995) is predominantly miombo, a deciduous woodland dominated by the leguminous tree genera Brachystegia, Julbernardia and Isoberlinia.
Composition and density of herbaceous layer of chipya, miombo and mateshe
In KNP no Brachystegia, Julbernardia, Isoberlinia or Uapaca species were found in the chipya plots, and no luxuriant herbaceous layer with chipya indicators was found in the miombo plots.

  Isoberlinia - Wikipedia, the free encyclopedia
Isoberlinia is a genus in the family Fabaceae (legume family) of five species of tree native to tropical Africa.
The leaves have three or four pairs of large leaflets and stout seed pods.
Local Malawi names include Sukwa mutondo for Isoberlinia angolensis and Tumbuka mbwerebwere for Isoberlinia stolzii.

TROUET, K. COPPIN and H. Tree ring analysis of Brachystegia spiciformis and Isoberlinia tomentosa: evaluation of the ENSO-signal, in the miombo woodland of eastern Africa
Growth rings, marked by terminal parenchyma, were visually detectable on carefully prepared stem discs of Isoberlinia tomentosa and Brachystegia spiciformis, dominant species of the miombo woodland in north-western Tanzania.
Cross-dating succeeded for eight out of thirteen samples for Isoberlinia tomentosa, but was unsuccessful for Brachystegia spiciformis.

Sampling of vegetation data took place in 72 permanent plots in the six dominant vegetation types (Savane herbeuse, Savane arborée, Savane boisée, Forêt claire à Isoberlinia doka, Forêt claire à Anogeissus leiocarpus and Forêt claire à Uapaca togoensis) and on gaps caused by felling of trees.
FA : Forêt claire à Anogeissus leiocarpus ; FI : Forêt claire à Isoberlinia doka ; FU : Forêt claire à Uapaca togoensis.
When compared to the biomass of Isoberlinia in the original stand, illegal logging lead to an export of more than 20% of the biomass of Isoberlinia during the last three years.

The Terminalia laxiflora and Isoberlinia wooded savannas cover extensive areas of the upland plains, with Isoberlinia savanna generally lying further to the south.
These savannas are interspersed with other less common types, including Combretum scrub or "ironstone meadow" where the ironstone pan is close to the surface, and form a mosaic distribution related to edaphic and topographic features.
The Terminalia savanna, in particular, is heavily used by the larger mammals, such as elephant, during the dry season, while the understorey of the Isoberlinia savanna is less well developed.

In the relatively arid corners in the northeast (Cameroon) and northwest portion (southwest Sudan) of the ecoregion, the transitional Isoberlinia spp.
Where human population remains sparse in central Cameroon and the Central African Republic, patches of dense dry forest remain, dominated by Isoberlinia doka with Afzelia africana, Burkea africana, Anogneissus leiocarpus, Terminalia spp.
The edges of drier type peripheral semi-evergreen rain forests growing among this grass-dominated zone have been severely degraded: regular grassland fires consume litter and small woody plants, creating a different structure from larger forest patches.

 The Miombo Network
Miombo is a vernacular word that has been adopted by ecologists to describe those woodland ecosystems dominated by trees in the genera Brachystegia, Julbernardia and Isoberlinia of the family Fabaceae, subfamily Caesalpinioideae (CSA/CCTA 1960; Wild and Fernandes 1967).
Ecologically similar Isoberlinia woodlands, lacking Brachystegia and Julbernardia, form the Guinea savannahs of West Africa (White 1983).

There are five distinct vegetation types: Isoberlinia tomentosa woodland; Isoberlinia doka woodland; Terminalia avicennioides savanna woodland; Gardenia scrubland; and riverine vegetation.
Dominant trees are Isoberlinia spp., which constitute over 80% of trees in the reserve.
The Isoberlinia woodlands and Terminalia savanna woodlands, which constitute of the vegetation in the reserve, should be protected from fires and burnt only once in three years before the early rains.

From the dry Central African savannas inhabited with Isoberlinia trees that are the favorite food of the giant eland to the dense scrublands of South Africa's Cape that are the habitat of the bushbuck, there has never been a more desirable group of antelope than the Magnificent Nine.
Follow in the tracks of the dainty bushbuck, the graceful common nyala, the shy sitatunga, the marathon-walking eland, the impossible bongo, the regal greater kudu, the high-altitude mountain nyala, the princely lesser kudu, and the largest of them all, the giant eland.

In the high-rainfall savannah ecosystems of southern Sudan fires kill certain fire-sensitive trees, e.g.
Isoberlinia doka, Daniellia oliveri, etc. and reduce the growth of other species.
Fires may reduce gum yields from Acacia senegal by up to 50 percent.

Open forest and savanna woodland characteristic of the Sudano-Guinean zone, occupies about 90% of the area, and gallery forest and dense dry forest, about 10%.
The forest is composed of many leguminous trees including Burkea africana, Detarium microcarpum, Afzelia africana, Daniellia oliveri, and Isoberlinia doka.
The gallery forests are dominated by Cynometra vogelii; the patches of dense dry forest by Isoberlinia doka, Anogeissus leiocarpus, Cola cordifolia, Antiaris africana, nationally threatened Chlorophora excelsa (V), and the edible 'akee' Blighia unijugata; and the flood plains by Hyparrhenia rufa.

The soil in the region is basaltic and slightly acidic (pH of 5.5) and has a clay texture, 4.9% organic matter (OM), 2.3% total N, 26 ppm P (Olsen), and low CEC.
The potential users of Stylosanthes in northern Cameroon are agropastoralists who own livestock and practice some level of cropping (maize and sorghum, usually intercropped with cowpea).
The region is typified by broken savanna vegetation, with shrubs and trees, such as Daniellia, Isoberlinia, Parkia, Lannea, and Pterocarpus, and a number of grasses, such as Andropogon, Hyparrehenia, Digitaria, Cymbopogon, Loudetia, and Pennisetum.

Forests grow in the highland areas that receive high rainfall.
The western and southern plateaus are primarily miombo woodland, which consists of an open cover of trees (notably Brachystegia and Isoberlinia), while in areas of less rainfall, bushland and thickets are found.
Thinly wooded grasslands cover areas where the original forest cover has been burnt off for human use.

Some 'dry country' species, such as Balanites aegyptiaca, Boscia angustifolia, B. salicifolia, Commiphora africana and Maerua angolensis, also occur both in the SomaliaMasai and the Sudanian Regions and have a quasicontinuous distribution.
Other species, more characteristic of higher rainfall areas, such as Amblygonocarpw andongensis, Burkea africana, Erythrophleum africanum, Isoberlinia angolensis (including L tomentosa) and Swartzia madagascariensis, do not occur in the SomaliaMasai Region and show an appreciable interval between their Zambezian and Sudanian areas.
Other 'wet country' species, including Acacia hockii, Combretum collinum (mechowianum), C. molle, Parinari curatellifolia and Piliostigma thonningii, though absent from typical Somalia-Masai vegetation occur there in small enclaves of pronounced Zambezian affinity.
