Texans combat lake-eating monster fern
In East Texas, Residents Take On a Lake-Eating Monster - New York Times
Caddo Lake, a mystical preserve of centuries-old mossy cypress breaks, teeming fisheries and waterfowl habitats, is under siege by a fast-spreading, Velcro-like aquatic fern, Salvinia molesta, also known as Giant Salvinia.
In what East Texans here liken to a horror movie, the furry green invader from South America, which is infiltrating lakes in the American South and abroad to growing alarm, is threatening to smother the labyrinthine waterway, the largest natural lake in the South, covering about 35,000 acres and straddling Texas and Louisiana.
“It’s probably the most dire threat that the lake has ever faced, and we certainly have had more than our share of threats,” said Don Henley, the drummer, singer and songwriter of the Eagles, who grew up in nearby Linden, keeps a double-wide trailer on Caddo Lake and has put his celebrity and fortune behind efforts to preserve it.
The United States Geological Survey calls Salvinia molesta one of the world’s most noxious aquatic weeds, with an ability to double in size every two to four days and cover 40 square miles within three months, suffocating all life beneath. The plant is officially banned in the United States, but it is carried from lake to lake by oblivious boaters, to the point where some private lake communities now limit access to boats already there.
