Hudson High School Students Learn About Giant Salvinia and Caddo Lake NWR

Region 2, May 8, 2013

On Wednesday, May 8, 2013, approximately 15 high school students and their teacher from Hudson High School, Hudson, Texas were treated to a short presentation on water management and the control of the non-native invasive aquatic plant, giant salvinia, through the introduction of the salvinia weevil and a tour at the Caddo Lake National Wildlife Refuge. Texas A & M CISE Extension Specialist, Lee Eisenberg gave the students a presentation explaining the use of natural biological controls such as the salvinia weevil can help control and reduce invasive aquatic plants like giant salvivia instead of using herbicides.


Staff from the refuge gave a short presentation on the history of the former LHAAP and how it is being transformed to a wildlife refuge. Discussions included a brief history of the ammunition plant and activities that occurred from 1942 to present and the ongoing cleanup and remediation that is continuing today. The students also were taken on a tour of the Refuge.
