Galveston Bay Invasive Species Risk Assessment Project

The Galveston Bay Estuary Program recently funded a risk assessment of invasive species of the Lower Galveston Bay Watershed. The project team consisted of staff from the Houston Advanced Research Center and the Environmental Institute of Houston at the University of Houston-Clear Lake.

The Galveston Bay Invasive Species Risk Assessment Project accumulated and assessed existing information describing the identity, characteristics, and impacts of exotic species invading natural ecosystems in the Lower Galveston Bay Watershed.

A risk assessment was conducted to identify current and potential invasive species posing the greatest risk to the ecology and human uses of the Lower Galveston Bay Watershed. Species were also ranked according to their ability to be prevented or controlled and the status of resources available for the management of invasive species.
