Invaded – the biological invasion of South Africa is a well-researched and written account of plant and animal invasions in South Africa. The book is beautifully illustrated with colour photographs throughout. The layout is neat and easy to follow, with numerous informative boxes highlighting subjects of particular interest. Leonie Joubert is an accomplished author and has also written two award-winning titles on climate change – Scorched: South Africa’s changing climate and Boiling point: People in a changing climate.
The rapid advance of human exploration and travel across the globe over the last few centuries has aided numerous seeds and stowaways to be transported to new environments. Many species were also intentionally relocated to new places to provide food and shelter for newly settled immigrants. The extraordinary and beautiful plants and flowers generated much interest among botanists and horticulturists who planted these species in gardens and parks in their homelands as well as newly established towns. Certain trees were propagated across the world for timber as they grew faster and denser than indigenous trees. Unfortunately, some of these species found these new environments free of natural predators with suitable conditions leading to rapid expansion – often to the detriment of indigenous species and water resources.
Invaded – the biological invasion of South Africa is divided into 17 chapters with a foreword written by the late Professor Kader Asmal, former Minister of Water Affairs and Forestry and the driving force behind the Working for Water project – one of the most successful environmental and job creation programmes in South Africa. The 17 chapters discuss the following topics:
- History and progression of biological invasions.
- Invasions in the Cape Floral Kingdom.
- The threat of woody tree invaders on our water resources.
- Marine invaders such as mussels, oysters and crabs.
- The invasive Argentine ant.
- Avian invaders such as the mallard and house crow.
- Triffid weed and its impact on the Nile crocodile.
- Spread of invasive plants along servitudes and transportation routes.
- Exotic grasses naturalised in South Africa.
- Eurasian wild pigs.
- The European wasp.
- Honeybees and reed frogs.
- Invasive alien fish and water weeds.
- Cats and mice on offshore islands.
- Genetically modified crops and global food security.
- Strategies to contain invasion.
- South Africa’s weedy exports.
The detrimental environmental and economic implications are only now starting to be fully realised and the cost to our economy and water resources has been the subject of many detailed studies. This book is a fantastic resource for students of invasion biology as well as anyone concerned about our environmental and economic future.

Mourning geckos are small, nocturnal geckos with a long tail and smooth skin. They range in colour from white and grey to brown and fawn. They are parthenogenic, which means the female reproduces independently of the male.
The softshell terrapin is an aquatic species that inhabits almost any type of permanent waterbody, including fast-flowing, large rivers, lakes, reservoirs, small, marshy creeks, farm ponds and desert springs. It is mainly carnivorous, feeding on crustaceans such as crayfish, as well as insects, small fish, worms, molluscs, tadpoles and frogs. It occasionally eats some plant material, although possibly by accident.
The South African Pet Traders Association (SAPTA) voted in their new committee for 2013 on Wednesday, 5 September 2012. The AGM was held at Exotic Aquariums in Boksburg North.
Serving on the newly elected committee is Adam Scott of Exotic & Wonderboom Aquariums, voted in as the Chairman. The Vice-Chairman is Arno Naudè of the Transvaal Herpetological Association. Craig Campbell of DARO and Campcon is the Treasurer and Daleen Buitendag remains the Secretary.
In addition to the above committee members, a further eight committee members were selected. These members include Ernst Moller of Die Visdam, Neil Stallard of Fish Designs in KwaZulu-Natal, Mohammed Jeewa of Wazeers Aquariums, William Kelly of Happy Koi, Sean Jefferis from The Planted Tank, Moolis Moolman from Pet Stop SA, Gavin Faulds and Gavin Marltons from Marltons Pets & Products.
Who is SAPTA?
The South African Pet Traders Association was established in 1990 as new legislation affecting the industry prompted the pet trade business to work together to form a unity for representation and protection of their interests.
The aim and business of the Association is to act on behalf of its members, in representing them in all applicable forums directly or indirectly in connection with the pet trade in general and acts as custodian for the protection, enhancement, regulating and self regulation of the trade. Membership is open to any pet trade business and is voluntary.
SAPTA also offer their members a range of animal keeping courses as well as regular updates on events and legislative affairs. For more information, visit the SAPTA website www.sapettraders.co.za
