A new website, www.invasiveswatch.org, has been launched to provide public information and promote cooperation and communication among governmental agencies, groups, and individuals dedicated to protecting area lakes from giant salvinia and other invasive aquatic species such as alligator weed, hydrilla, and water hyacinth.

The website focuses on Caddo Lake and Lake O’ the Pines in Northeast Texas and Lake Bistineau, Black Bayou, Cross, and Wallace lakes in Northwest Louisiana. The tool is expected to be expanded to the other lakes.

The website was developed by the U.S. Geological Survey’s National Wetlands Research Center for the Caddo Lake Institute under a grant from the National Fish & Wildlife Foundation. A unique feature of the site is a map tracking tool that the public can view to monitor recent chemical and biological treatments and the observations of volunteer weed wardens.

The site is the centerpiece of the Great Raft Invasives Program, a public information and education effort to reach residents and visitors to the six principal lakes in the region. Giant salvinia and other invasive aquatic plants and animals are known to travel from lake to lake on the boats, trailers, and equipment of anglers and others enjoying outdoor recreation as they move from one lake to another.
