Passing the Torch

The Center for Invasive Species Eradication program that funded the construction of the weevil rearing facility at the Caddo Lake National Wildlife Refuge and much of the salvinia weevil research over the last four years has come to an end. Funding for the program expired in July 2014.

Prior to its closing, plans were made to transfer the greenhouses at the refuge over to the Texas Parks and Wildlife Department to operate. They will continue to raise as many weevils as possible at this facility for use at Caddo and other lakes in the area.

Assistance was also provided to the Greater Caddo Lake Association of Texas and the Caddo BioControl Alliance, a newly forming non-profit organization that will manage the "Morley Hudson Weevil Greenhouse at Caddo Lake." This is a true grass roots effort to deal with the giant salvinia on Caddo Lake with local resources. Lofty goals have been set for this facility, but with continued support and perseverance, significant progress can be made. To learn more about this facility and contribute to the cause, visit the Greater Caddo Lake Association of Texas website. In the video below, GCLA President Daren Horton gives an overview of the newly established facility.

Salvinia Weevil Research at Caddo Lake...The Next Viral Videos: Part One

A few weeks ago, Jack Canson, a local advocate for Caddo Lake shot some video at the Giant Salvinia Weevil Rearing Facility at the Caddo Lake National Wildlife Refuge that explains the program and the progress made over the last 4 years...all in less than 10 minutes of video!  They are single take videos, so they are definitely no polished Presidential speech or anything like that. Regardless, they get to the point and describe the great local support for the effort as well as the lessons learned over the years.



Thanks Jack for shooting, editing and posting these videos.

And here is the third and final installment.

Grass Roots Rising Up Against Giant Salvinia

A new project is underway on the banks of Caddo Lake in an effort to take back the lake. Giant salvinia has had its grips on the lake for nearly a decade now and shows no sign of slowing down. Harsh winters will set it back, but only for a while. Chemicals will knock it out, but it comes back. The past 6 months have seen salvinia coverage on the lake reach its highest level yet only to be pummeled by several rounds of extended cold. Through it all, the threat of salvinia remains great.

This lingering threat and the desire to "keep Caddo Lake Natural" is really the driving force behind a grass roots effort to do something about giant salvinia. The Greater Caddo Lake Association of Texas (GCLA) began fund rasing last year and has now begun construction on a lake side salvinia weevil rearing facility. This facility will be similar to the Center for Invasive Species Eradication (CISE) facility at the Caddo Lake National Wildlife Refuge and a sister facility operated by the Texas Parks and Wildlife Department.

A key difference in the GCLA facility and the CISE facility is their primary mission: production vs. research. Being located on the Lake, the GCLA facility will have access to a ready supply of water that is quite suitable for salvinia growth. Easy lake access is another benefit as is the publicity that the facility will receive on the lake's shore.

Much work is left to be done, but GCLA hopes to have the facility up and running early in the 2014 growing season. They of course can use your support and appreciate help in spreading the word. Visit their website at www.gclaoftx.com.

They also have some YouTube video to help explain what they are doing. Check it out below. http://youtu.be/pKe3xvEEjpY
