Alien invasive species in Africa's wetlands : some threats and solutions

Wetlands in Africa are increasingly being recognised as ecosystems of extreme importance to man and biodiversity. However, the management of these wetlands has been impacted by alien invasive species that specialize on aquatic (and semi-aquatic) systems. This booklet introduces alien wetland invaders by describing seven of the worst species already introduced to Africa and mentions several others that are potential threats. It is hoped that this publication will raise the awareness of those concerned and provide them with sources for information and technical assistance.
