The Department of Environmental Affairs (DEA) published the Alien and Invasive Species Regulations on Friday 1st August, 2014. A total of 559 alien species are now listed as invasive, in four different categories. A further 560 species are listed as prohibited, and may not be introduced into the country.
Centre for Invasion Biology (C.I.B) researcher, Charles Griffiths, is a co-author on a recently-published study that shows major changes in the invertebrate community of a small, urban estuary resulting from the proliferation of alien reef-building worms, Ficopomatus enigmaticus.
Burrowing nematode is a parasite of plants, and it is a pest of many agricultural crops. It is an especially important pest of bananas and citrus, and it can be found on coconut, avocado, coffee, sugarcane, other grasses, and ornamentals. It is a migratory endoparasite of roots, causing lesions that form cankers. Infected plants experience malnutrition.
