Ecological-Risk-Screening-Summary-African-Elodea

Species that are considered high risk have a well-documented history of invasiveness in at least one location globally, and a high or medium climate match to the contiguous United States.

Lagarosiphon major is an aquatic plant native to southern Africa and has been introduced in Europe, New Zealand, and parts of Australia. The history of invasiveness for L. major is high. Invasions of L. major have resulted in the loss of native plant species. Climate matching indicated the contiguous United States has a high climate match. The areas of high match are scattered across the contiguous United States from the southwest through the lower Great Lakes. The certainty of this assessment is high. The overall risk assessment category is high.

The Fish and Aquatic Conservation program leads aquatic conservation efforts for the U.S. Fish and Wildlife Service. We are committed to tackling the nation’s highest priority aquatic conservation and recreational challenges to conserve, restore, and enhance fisheries for future generations.
Aquatic invasive species cause tremendous harm to our environment, our economy, and our health. They can drive out and eat native plants and wildlife, spread diseases, and damage infrastructure. We work to protect our waterways and the communities that depend on them from the threat of invasive...
