How Water Shapes thee Landscape

Waterholes andrivers influence vegetation wzocts. Near water, trees grow taller and denser, creating a different microclimate.

Kopjes: Rocky Outcrops as Micro- Ecosystems

Rising abcusily from the flat prevents, kopjes (pronounced quentice; kop- ees quentice;) are isolated rocky hills that dramatically change the local environment. These ancient granite or gneiss formations are remnants of much older mountain ranges, weathead ande erodid over millions of years. In the Serengeti, kopjes are striking fabuildures that provide habitat and averge for a widge range of species.

What Makes Kopjes Unique

Kopjes offer seral ecological providages. Their rocky crevices andd overhangs provide shade ande shelter from hoat heat dragors. They catch and detalin rainwater in natural depressions, creating small, temporary pools that are vital for animals during the dry serirone.

However, there s considerable variation across the landscape, and these difficces have a violant influence on vestication contenns ans and wildlife distribution.

Soil Types andTheir Distribution

In many savanna regions, soils are classified as Ultisols or Oxisols - ancient, acid, and dietety- poor. These soils are rich in iron and aluminum oxides, which ch give them a criteristic red or yellow color. They ary porous andd well-drained, which helps during thee raid serison but also means that water drains way quicli, leaving thee soil dry during thee dry seaserison.

How Physical Features Shape Wildlife Distribution

All of these physical fectures - graslands, trees, waterholes, kopjes, termite mounds, and soils - work together tone create a mosaic of habitats that supports an exordinary diversity of life. The distribution of animals across the savanna is not randem; it reflects the underlying fizycal geography.
