Mlawula Nature Reserve - Fauna
In general, very little is known about the invertebrates of the reserve, although there may be as many as 20,000 species of insects and 10,000 species of spiders.
The variety of topography and ecotypes enables a large variety of vertebrates to exist in the reserve. The reserve is noteworthy for its high diversity of birdlife, with about 350 species having been recorded in the area, compared with the total of 496 species recorded in the whole of Swaziland. The 64 species of small and large mammals have been recorded in the reserve, includes those species which have been re-introduced.
