Celtis mildbraedii is a species of forest tree in the family Cannabaceae. It was previously assigned to the family Ulmaceae. These trees grow in limited areas of South Africa, Mozambique and Zimbabwe. They are also found in forested areas from West Africa to Sudan, DRC, Angola and Tanzania. Common names include natal white stinkwood, red-fruited white-stinkwood and natal elm. This species is more common in Tropical Africa than in Southern Africa.
There are about forty specimens in Pigeon Valley Natural Heritage Park, Durban, South Africa. [4] The southernmost specimen is found in Ilanda Wilds Nature Reserve in Amanzimtoti. [5] [6]
The fruit of the tree turns red as it ripens but viable seed is difficult to find. [7] No Natal White Stinkwoods were available from plant nurseries in South Africa in 2009 suggesting that this tree species is not being propagated, despite its rarity in South Africa. [8]
This tree is a dominant species in the moist semi-deciduous forests of Ghana along with Triplochiton scleroxylon and African Mahogany ( Khaya ivorensis ). [9] The trees were common in Ajenjua Bepo and Mamang River Forest Reserves in Ghana. [10]
In Uganda the tree is used for timber and is a primate food source in Budongo Forest Reserve. A study of correlations between seedling and adult tree densities of Celtis mildbraedii here, suggested that this species had a healthy regeneration pattern. [11]
Hlatikulu Forest is a coastal scarp forest in the Lebombo Mountains of South Africa, between Ingwavuma and the Pongola Gorge. The forest is also known as the Gwaliweni Forest.
Stinkwood, german Stinkholz, french Bois Puant, is the common name for a number of trees or shrubs which have wood or plant parts with an unpleasant odour, including:
Celtis africana, the white stinkwood, is a deciduous tree in the family Cannabaceae. Its habit ranges from a tall tree in forest to a medium-sized tree in bushveld and open country, and a shrub on rocky soil. It occurs in Yemen and over large parts of Africa south of the Sahara. It is a common tree in the south and east of southern Africa, where the odour given off by freshly-cut green timber is similar to that of Ocotea bullata or Black Stinkwood.
Pigeon Valley is a Natural Heritage Park and formally declared municipal nature reserve in Durban, South Africa. It is an unusual example of an urban reserve with very high levels of biodiversity. It was established to provide protection for the Natal elm and other forest giants of the coastal climax forest. Another rare tree that occurs here is Natal forest loquat, which is endemic to the Durban area and to oNgoye Forest.
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, 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. The forest of almost 4,000 ha covers an extensive granite ridge that rises from 200 to 460 metres above sea level. It is found some 10 km inland, or 16 km by road, from the coastal town of Mtunzini, and adjoins smaller forest reserves on its periphery, namely Impeshulu in the west, Ezigwayini in the north, and Dengweni in the south.
Rauvolfia caffra is a tree in the family Apocynaceae. It is commonly known as the quinine tree. These trees are distributed from the Eastern Cape of South Africa to tropical Africa and are found in low-lying forests near rivers and streams, or on floodplains.
Ngome Forest is situated to the east of Vryheid, KwaZulu-Natal, South Africa. This is a unique forest, being transitional between Mistbelt Forest and Coastal Scarp Forest. The area has been protected since 1905, and forms part of the Ntendeka Wilderness Area.
The Karkloof Forest is situated in the Karkloof Nature Reserve, 22 km north of Howick, KwaZulu-Natal, South Africa.
Millettia grandis is a species of plant in the family Fabaceae from South Africa. It is commonly called umzimbeet which is a name derived from the isiZulu name umSimbithwa.
Ekebergia capensis is a tree in the family Meliaceae. It is commonly known as the Cape ash. Its range extends from the Eastern Cape of South Africa to Sudan and Ethiopia. It has been introduced onto Ascension Island.
KwaZulu-Natal coastal lowland forest is a subtropical forest type that was once found almost continuously along the low-lying coastal areas of KwaZulu-Natal, South Africa. It still exists in protected areas, but much has been cleared for sugar-cane plantations and housing developments.
KwaZulu-Natal Dune Forest is a subtropical forest type that was once found almost continuously along the coastal dunes of KwaZulu-Natal, South Africa. This vegetation type develops in sheltered areas behind the littoral zone, where with some protection from the salt wind it may develop with canopies as tall as 30 m. It still exists in protected areas, but much has been degraded by human activity. Coastal dune forest covers approximately 1% of the land area of KwaZulu-Natal, and is a habitat type seriously threatened from human population pressure and development, particularly titanium mining.
Southern African Sand Forest is a sand forest, or a subtropical forest plant community of the tropical and subtropical dry broadleaf forests biome. It grows on ancient sand dunes in northern KwaZulu-Natal and southern Mozambique. In South Africa these forests are known simply as Sand Forest, while in Mozambique they are known as Licuati Forest. The Southern African sand forest is part of the Maputaland coastal forest mosaic ecoregion.
Bridelia micrantha, the mitzeeri or the coastal golden-leaf, is a tree in the family Phyllanthaceae and is native to tropical and southern Africa as well as to the island of Réunion in the Indian Ocean.
Celtis zenkeri is a species of flowering plant native to sub-Saharan Africa.
Capparis fascicularis, the zigzag caper-bush, is a plant in the Capparaceae family and is native to Africa.
Combretum kraussii, the forest bushwillow, is a medium-sized to large tree of eastern South Africa, Eswatini and southern Mozambique, which is found within, or in the vicinity of forests. The specific name commemorates Dr. F. Krauss who undertook a collecting trip to South Africa from 1838 to 1840.
Protorhus longifolia, the red beech, is a medium to large, mostly dioecious species of tree in the family Anacardiaceae. It is native to South Africa and Eswatini, where it occurs in well-watered situations from coastal elevations to 1,250 m. The leafy, evergreen trees have rounded crowns and usually grow between 6 and 10 m tall, but regularly taller in forest.
The Victoria Basin forest–grassland mosaic is an ecoregion that lies mostly in Uganda and extends into neighboring countries. The ecoregion is centered north and west of Lake Victoria, with an outlier on the border of Ethiopia and South Sudan.
