This type of grassland has a high conservation value as most has been lost to development. Most of the threatened plants of the area occur in grasslands and include orchids, succulents and bulbs. Out of every six plants in a grassland, only one is a grass. Grassland plants are often overlooked, particularly in winter when they die back to survive the frost and fires. Large underground tubers, bulbs and rootstocks are typical of grassland plants. These are often highly sought after in the medicinal plant trade and may occur nowhere else.
Off road driving, dumping of rubbish, unplanned fires, excessive fire breaks, removal of top soil, poaching of plants and the uncontrolled spread of alien invasive plants, such as, pines, gums, wattles, bramble and cotoneaster are degrading the grasslands and have led to extinctions.
Patches of indigenous Afromontane and riverine forest add to the biodiversity. Most people appreciate the time it has taken for a giant Yellow Wood or a Matumi tree to grow. Illegal felling of trees seldom occurs and is usually seen and reported.
Vine harvesting for making baskets is a problem in forests. Research by the Department of Water Affairs and Forestry show that they do not grow back and attempts to grow from seed or cuttings has failed.
