Pulling and pulling and pulling...

After about five weeks, crews at Lake Wilson in Hawaii have managed to remove 26,000 cubic yards (19,900 m^3) of the Salvinia molesta that has infested lake waters, which amounts to about 25 percent. According to this article from the Honolulu Advertiser, the weeds they're pulling are dead after being sprayed with herbicide a few weeks ago. The article also mentions a similar project going on at Kawainui Marsh, where volunteers are removing salvinia as well as water lettuce (Pistia stratiotes). It is probably frustrating for Hawaiians to know that no matter how good of a job they do, this is likely a lifetime maintenance project, given the difficulty in eradicating any aquatic species.
