Another documented report of giant salvinia along the Texas-Arkansas border was confirmed by Texas Parks and Wildlife last week, creating additional concern from Arkansas Game and Fish Commission biologists about the nuisance plant's spread into The Natural State. Giant Salvinia is a free-floating South American plant, similar in appearance to duckweed but much larger. It stays at the water's surface and can rapidly cover a large area and choke out all life in the water beneath if left unchecked. Arkansas's first confirmed case of giant salvinia entering the state was documented in 2017 in Smith Park Lake in Miller County followed shortly after by sightings in Sulphur River Wildlife Management Area. It was confirmed in Lake Erling in December 2018 and Lake Columbia in 2019. Anyone spotting giant salvinia in an Arkansas lake is encouraged to call the AGFC's Fisheries Division at 800-364-4263 to report the location.
