Kruger NP Basalt-Granite

The map shows the two main types of geology found within the Kruger National Park (KNP) – basalt and granite – and is mainly used for research purposes. Basalt is a fine grained, dark coloured volcanic igneous rock while granite is a coarse grained, light coloured plutonic igneous rock. The distinct characteristics between these two types of geology play a significant role in the manner in which the vegetation is distributed in the KNP. The basalt has a high nutrient content resulting in higher grass production with fewer trees and has higher fire intensities. Because of its porous nature, the granite has more water infiltration, deeper soils and thus denser woody cover and less herbaceous cover.

Kruger NP Geology

This map shows the main geology of the Kruger National Park (KNP). The KNP is categorised into seven different geologies: basalts; conglomerates; gabbros; granites; rhyolites; sand deposits and shales. The geological richness of the landscape results in a great diversity of plants which provide support to the wildlife of the KNP.
The map is based on the 1991 dataset created by F.J. Venter.

Kruger NP Elevation

The elevation map for Kruger National park (KNP) is a hillshade map that simulates the shadow thrown upon earth by the elevated features. This results in a 3D effect that helps users visualise the terrain. This hillshade was created using the 20m NGI contour lines.

Kruger NP Landscapes

A landscape is defined as an area with specific geomorphology, climate, soil and vegetation patterns, and associated fauna. It is mainly used for management planning and ecological studies in the Kruger National Park (KNP). The landscapes of the KNP shown in this map use the W.P.D. Gertenbach dataset of 1983, as published in Koedoe 26: 9-121 (1983).

Kruger NP Landsystems

Landsystems are areas or regions with recurring patterns, generally seen in terms of landform, underlying geology and vegetation. This dataset has been categorised into eleven landsystems using dominant woody vegetation. It is mainly used for management planning and ecological studies in the Kruger National Park (KNP).
The land systems of the KNP shown in this map use the F.J. Venter dataset of 1990, from his dissertation: A classification of land for management planning in the Kruger National Park.

Mapungubwe NP Soil

The Mapungubwe National Park (MapNP) Soil map shows the main soils found in the park, as per the Peace Parks Foundation data. As a result of its geological richness and associated mineral deposits the MapNP has become increasingly under threat due to encroaching mining activities.
