Probleemplante en Indringeronkruide van Suider-Afrika
Southern Africa has possibly the most beautiful and diverse floral kingdom in the world, but it is also the most polluted and threatened. Agricultural production is under threat from both indigenous and alien weeds and our entire ecosystem is now being seriously threatened by these alien, invasive species. Awareness of these weeds, the regulations involved and possible control measures have become critical factors. Things change in time, more weeds appear and the scope of this edition is extended up into more Central Africa. This then initiated the fourth revised and updated edition, titled Problem Plants and Alien Weeds of Southern Africa.
- The contents cover more than 800 problem plants of which 433 species are illustrated and their origin, environmental impact and control measures are described. Similar species are mentioned.
- More than 900 colour photographs assist with identification, create more awareness and illustrate the problematic nature of plants.
- Up-to-date distribution maps show the range in Southern Africa.
- The existence of a herbicide registration (in South Africa) is indicated with “H” where applicable, and the latest government regulations (NEMBA categories: 1a, 1b, 2 and 3), as well as biological control, where applicable, are mentioned next to the distribution map.
- Introductory chapters cover biodiversity and the threat of alien species; problematic indigenous vegetation including bush encroachment; veld degradation; control and management techniques; biological control; chemical weed control; herbicide resistance, and the threat posed by ornamental garden plants.
