These are the plants which have been declared Weeds and Alien Invader Plants in South Africa in terms of the Regulations pertaining to the Conservation of Agricultural Resources Act 43 of 1983 as amended. For more information, about alien plants please see:
Declared Weeds & Alien Invader Plants are divided into three categories:
Category 1 Plants. This is the strictest category. These plants may not occur on any land or inland water surface other than in a biological control reserve. Except for the purposes of establishing a biological control 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 Plants. These are plants with a commercial application and may may only be grown in demarcated areas (or biological control reserves). See the Government Gazette listed below for details relating to demarcated areas. Other provisions of category 1 apply.
Category 3 Plants. The regulations regarding these plants are the same as for category 1, except that plants already in existence at the time of the commencement of these regulations are exempt, unless they occur within 30 metres of a 1:50 year flood line of river, stream etc.
These lists have been compiled from the information published in R.280 in the Government Gazette Vol 429: No 22166 of the 30 March 2001. R280 contains amendments to the regulations pertaining to the Conservation of Agricultural Resources Act no 43 of 1983. For more information regarding these regulations, please see the Government Gazette (available from the Government Printer: Pretoria or Cape Town).
