Identification Keys and Factsheets for Invasive Alien Species for Eastern Africa Published by BioNET – EAFRINET (Nov 7, 2012)
East African Network for Taxonomy.
Under the UVIMA Project a list of over 100 of the most serious invasive plant species in the region was produced. This list was used as a basis for the production of a key to 119 species of invasive plants. There are also fact sheets to each of these species. The key is designed to be used as a simple identification tool for conservationists, extensionists and some farmers, to provide an overview of the invasive plant species and possible management measures and to provide first port of call for somebody interested in invasive plant species in the region (links to more detailed sources of information are provided).
Cajun Crayfish Invading Africa, Eating Native Species (Jan 9, 2012)
Without any native predators to keep it in check, the Louisiana crayfish, also known as the red swamp crayfish, is gobbling up small freshwater fish, fish eggs, mollusks, crustaceans, and aquatic plants. (See pictures of freshwater plants and animals.) The 6-inch-long (15-centimeter-long) invader is already widely distributed in lakes and other bodies of water throughout Kenya, as well as in Rwanda, Uganda, Egypt, Zambia, the Seychelles, Mauritius, and South Africa. Conservationists are now concerned the crayfish will reach the East African lakes of Malawi, Tanganyika, and Victoria, which are home to hundreds—and probably thousands—of species found nowhere else.
