The narrow coastal belt between the escarpment and the sea has an average altitude of 300 m. The area has a summer rainfall pattern except in the northeastern part, rainfall could occur throughout the year. Along the coast the climate is influenced by ocean winds and mountains on the northern boundary which is well clothed with vegetation, aiding the retention of nimbus clouds. Almost the entire area consists of sedimentary rock, sandstone, and shale. Elytropappus rhinocerotis is widespread along the coastal belt, giving protection to many Haworthias in this area.
The coastal belt hosts almost all of the vegetation types in South Africa except Succulent Karoo. The greater part of this area belongs to the Albany Center of Endemism, which contains high plant species richness due to the presence of different phytochoria and species at the ends of their distribution ranges. This area contains the highest density of Haworthia species and populations, including H. chloracantha, H. floribunda, H. mirabilis, H. mutica, H. parksiana, H. pygmaea, H. retusa, H. rossouwii, H. variegata, H. venosa, T. kingiana, T. marginata, T. minima, and T. pumila.
