Warthogs use their tusks both for fighting off unwanted predators and other competing male warthogs, and the warthogs also use these tusks for digging in the dirt for grubs and insects. Warthogs have a diet that consists mainly of grass, fruit, berries, roots and insects but warthogs are also known to occasionally eat small mammals, birds and reptiles. The diet of the warthog however, depends on the season and what is growing and therefore available for the warthog to eat.
The Robberg Peninsula is conserved for several reasons. The mainland connects to an island through a spit called a tombolo. This results from waves sweeping around both sides of the island. Similar to other rocky headlands on this coastline, Robberg Peninsula supports a diverse array of plants and animals that have adapted to this land/sea ecology. But what sets it apart is the distinctive climbing-falling dune (one of only seven on this coastline). The bedrock of the peninsula was dated to the prehistoric breaking up of Gondwanaland and evidence of this can be seen at several sites. Besides the unique and fascinating typography, evidence of middle and later Stone Age inhabitation was found in a few of the caves. It is for this reason that the reserve was proclaimed a national monument.
The forest floor, also called detritus, duff and the O horizon, is one of the most distinctive features of a forest ecosystem. It mainly consists of shed vegetative parts, such as leaves, branches, bark, and stems, existing in various stages of decomposition above the soil surface. Although principally composed of non-living organic material, the forest floor also teems with a wide variety of fauna and flora. It is one of the richest components of the ecosystem from the standpoint of biodiversity because of the large number of decomposers and predators present, mostly belonging to invertebrates, fungi, algae, bacteria, and archaea. Certain (adapted) plants may be more apparent in tropical forests, where rates of metabolism and species diversity are much higher than in colder climates.
