Pondoland Centre of Plant Endemism

Last updated

The Pondoland Centre of Plant Endemism is situated in the coastal region overlapping the provinces of KwaZulu-Natal and the Eastern Cape in South Africa. It is named after Pondoland and falls within the Maputaland-Pondoland-Albany Hotspot. The region consists of grassy plateaus incised by forested ravines and gorges. The main substrate in the area is Natal Group Sandstone, which was formed by sediments laid down about 500 million years ago in a rift underlying the eastern Agulhas Sea in the ancient continent of Gondwana. [1] The region is about 18,800 hectares in extent, and lies along the coastline stretching about 15 kilometres inland with a maximum altitude of about 400 to 500 metres above sea level. [2] The region is essentially a transition zone between sub-tropical and temperate climates.

Endemics

Some notable endemic plants include Sanderson's bladderwort ( Utricularia sandersonii ), the pondo coconut ( Jubaeopsis caffra ), the Pondoland ghost bush ( Raspalia trigyna ), the Pondoland conebush ( Leucadendron pondoense ), pondo khat ( Catha abbottii ), pondo waterwood ( Syzygium pondoense ) and pondo poison pea ( Tephrosia pondoensis ).

An endemic species of lizard, the pondo dwarf chameleon ( Bradypodion caffrum ), is also found only in this region.

They were formed nearly two million years ago by faulting and uplifting, and are composed of Precambrian metamorphic rocks. They are split into two sub-ranges; the West Usambaras being higher than the East Usambaras, which are nearer the coast and receive more rainfall.

<span class="mw-page-title-main">Forests of KwaZulu-Natal</span> Forest vegetation type in South Africa

Areas of forest which grow in KwaZulu-Natal, South Africa mostly on south facing slopes in higher rainfall areas, and along the humid coastal areas. Different types of forest can be identified by their species composition which depends mostly on the altitude, latitude and substrate in which they grow. South facing slopes are favourable for the development of forest as they are more shaded, and therefore cooler and retain more moisture than the northern slopes. The extra moisture on the south slopes is not only favoured by forest trees, but also helps to prevent or subdue wildfires. Fires can also be blocked by cliff faces and rocks or boulders on these slopes, and by streams or rivers at the base of the slopes. The coastal regions are conducive to forest formation, because of high rainfall and humidity which are favoured by forest trees and also help to prevent or subdue fires. The rivers of the coastal areas are also broader than further inland, which may often prevent fires from spreading long distances, and fires generally burn uphill and therefore more often away from areas at low altitude.

oNgoye Forest

oNgoye Forest, also known as Ngoye or Ngoya Forest, is an ancient coastal scarp forest, protected by the oNgoye Forest Reserve in South Africa's KwaZulu-Natal province.

<i>Dalbergia armata</i> Species of legume

Dalbergia armata is a scrambling, deciduous species of legume that is native to subtropical to temperate regions of southeastern Africa. The robust, woody liana or small tree is armed with strong spines on the main stem and branches. It occurs sparsely or commonly in forest, bush, riparian fringes and in wooded ravines.

The site is characterised by high endemism of plant species and threatened invertebrates including seven endemic species of the enigmatic beetle genus Colophon and 14 butterfly species. It provides a migratory route for large mammals such as the leopard and serves as a nursery for marine species.
