Invasive plant moving into other East Texas lakes

MARSHALL, Texas (AP) — Texas Parks and Wildlife Department officials say an invasive plant that’s become a problem on Caddo Lake has been spread to at least four other East Texas lakes.

The non-native giant salvinia is showing up on boat ramps at Lake O’ the Pines, Lake Wright Patman, Lake Gilmer and Lake Murval.

Agency spokesman Lynn Wright tells the Marshall News-Messenger boaters accelerate the plant’s march through the state’s lakes because it clings to boats and trailers. A single plant can double in just a week.

The plant grows to a thick carpet on the lake surface, blocking light for other plants beneficial to fish. Once established, the salvinia is nearly impossible to eliminate.

The problem is severe this year on Caddo Lake, where most boat ramps are clogged with it.
