INVASIVE SPECIES WORK

For many years, the ecological and recreational values of Caddo Lake have been threatened by a number of non-native plants and animals, such as hydrilla, water hyacinth, Chinese tallow and nutria. In 2006, the latest invasive species – giant salvinia – was found in the lake, and it may pose the greatest threat because of its rapid growth. CLI has taken a lead in coordinating efforts of local communities and state agencies in Texas and Louisiana for public education and experimentation with management tools for controlling giant salvinia and other aquatic invasive species. The projects CLI has initiated or in which it has played a significant role are below.

• Great Raft Invasives Program
• Pocket Guide to Invasive Species of the Lakes of the Great Raft
• Salvinia Weevil Rearing Facilities
• Interagency Giant Salvinia Control Team
• Mechanical Harvester
• Giant Salvinia Barrier
