The Quiet Invasion: A Guide to Invasive Species of the Galveston Bay Area was created through a partnership among the Estuary Program, Texas Parks and Wildlife, and Houston Advanced Research Center in 2006. The field guide includes a list of 103 species of invasive plants, animals, and insects that threaten Galveston Bay ecosystems. Each entry has useful information such as habitat, distribution, and identification markers for each species.

The Quiet Invasion website was updated in 2017 and allows users to search through the library of invasive species with helpful filters and tools. The website also provides information on the threat of invasive species and what you can do to stop their spread.
