Aquatic Herbicide, Renovate OTF Kills Banded Mysterysnail in Adirondacks
In an effort to control the invasive aquatic plant, Eurasian watermilfoil on Lake Luzerne, federally certified Renovate OTF was applied. The active ingredient, triclopyr, is designed to target just broad leafed plants including the invasive milfoil. The herbicide devastated the banded mysterysnail population, causing a die-off.

The Adirondack Council views the snail die-off as evidence that Renovate is far more damaging to animal life in general than believed by regulators. The snails, a common prey species for birds and larger fish, could be spreading the toxic agent throughout the ecosystems after they’re eaten.

Stormwater Pollution is Killing Coho Before Spawning - Researchers at NOAA’s Northwest Fisheries Science Center in Seattle worked with collaborators, including the U.S. Fish and Wildlife Service, local tribes and the Wild Fish Conservancy, to survey 51 sites from 2000 to 2011 in streams all over the Puget Sound basin. They used the survey data with a new computer model to map predicted coho death rates. The results show that in an estimated 40 percent of their range in the Puget Sound Basin, 10 to 40 percent of coho salmon die before they can even spawn because of pollution.
