Owners and visitors to Marloth Park are requested to report any observed specimens to myself 9 , Ronelle Kemp 10 or the National Botanical Institute in Pretoria. Another rare plant is the summer impala lily Adenium swazicum that resemble the common impala lily Adenium multiflorum in growth form. However, Adenium swazicum is restricted to black, Arcadic soils with a high clay contents, whereas Adenium multiflorum is usually associated with poor soils and a rocky substrate. The root of Adenium swazicum is adapted to the extreme swelling and shrinking properties of the soil, by a large succulent root that compensates for these environmental fluctuations. The leaves of Adenium swazicum are lanceolate and covered in fine dense hair. Adenium swazicum flowers in summer with a profusion of bright pink flowers. Adenium multiflorum, however, flowers in winter with a profusion of white flowers with a bright red corona. Distribution is apparently restricted to a small number of plots along Berghaan Street and Naboom Street, just off Seekoei Road. Notably, Adenium swazicum is found in high densities on plots 3246 to 3256. However, these plants are also found on neighbouring plots with Arcadic soils and a high seasonal moisture regime. It is recommended that some protective measures be implemented on Marloth Park to ensure species survival. Where development has been approved it is important that cognisance be taken on occurrence of this plant species, and where necessary that plants affected by the development be removed and relocated to a suitable environment before construction begins. The presence of red data species cannot be discounted due to the extent of the area, seasonal variation and phenology of plant species. It is recommended that an ecological impact study be conducted on each plot, before approval of any development, to assess the potential occurrence other red data plant species. 9 Ben Orban.

NOXIOUS AND INVASIVE WEEDS An invasive plant species can be defined as any plant that propagates itself to such extend that the density that ensue is considered detrimental to biodiversity and the natural vegetation that occur in that region. Although all plant species has the inherent ability to increase their distribution under favourable conditions, most invasive plant species are alien to the country and their rapid spread can be attributed to the lack of species competition and the absence of natural control pathogens. Thus, any plant species that increases their density and distribution to such extend that it considered detrimental to the development objectives can be considered an invasive plant species. Many alien plant species in South Africa do not reveal the inherent ability to propagate itself to such extend that it is considered undesirable. These undesirable plant species, as specified in regulations pertaining to the Conservation of Agricultural Resources Act 43 of 1983 and amended in the Government gazette Vol 429: No 22166 of 30 March 2001, necessitated the classification of undesirable plant species according to three categories, based on the invasive properties and potential commercial benefit of retaining some of these plants in demarcated areas under controlled conditions. The following three categories pertain to declared weeds and alien invader plant species: Category 1 These plants may not occur on any land or inland water surface other than in a biological control reserve. Except for the purpose of establishing a biological reserve, one may not plant, maintain, multiply or propagate such plants, import or sell or acquire propagating material of such plants except with the written exception of the executive officer. Category 2 These are plants with a commercial application and may only be grown in demarcated areas or biological reserves. Category 3 The regulations regarding these plants are the same as for Category 1, except that plants already in existence at the time of these regulations are exempt, unless they occur within 30 metres of a 1:50 year flood line of river or stream. The affects of invasive plants Alien invasive plants have the competitive advantage over indigenous plant species and often out-compete indigenous species for natural resources, thus reducing the species diversity. © Ecological Associates/ Marloth Park 92
