Red River Waterway Commission exploring alternative approach for giant salvinia

Natchitoches, LA … The Red River Waterway Commission is exploring alternative control methods in order to combat the spread of giant salvinia in the Red River. For the past several years, there has been a widespread infestation that, if left untreated, can be detrimental to the river and its surrounding areas.

Giant salvinia is one of the most invasive rapid-growing aquatic plants that dominate water bodies by overgrowing and replacing native plants that provide food and habitat for animals and waterfowl. Once it is established, the plant blocks out sunlight. These conditions lead to unhealthy aquatic ecosystems and a decreased quality fishery.

“The real issue is that the giant salvinia will quickly take over a lake and greatly reduce the recreational aspects of that area,” said Mike Boydstun, Director of Operations at the Red River Waterway Commission. “One of our goals on the Red River is to avoid that type of situation by controlling the spread of giant salvinia as much as possible.”

Different control measures are available. In addition to mechanical removal and spraying with herbicides, Red River Waterway officials have implemented a biological method by releasing salvinia weevils in the infested areas of the river. Once they are released, these weevils gravitate towards the salvinia and eat the leaves of the plant, completing their life cycle.

Research biologist Lauren Cozad has done extensive research on the relationship between the weevils and giant salvinia. “Both the plant and the weevil are native to Brazil. Once the plant became a problem, researchers started colonies of weevils in order to try and control the giant salvinia that’s currently a problem in the States.”

Boaters can also help prevent the spread of giant salvinia by following three steps: CLEAN, DRAIN, & DRY. It is important to clean the boat and trailer once it is out of the water and remove any visible salvinia. Boaters should also remember to drain all water from the boat before leaving the river/lake and allow it to dry out completely for one week or more before returning to the water. If you are unable to remove all vegetation from underneath the boat, then allow the vegetation to dry completely for a period of 3 weeks.
