Izaak Walton League

The Izaak Walton League of America, Inc. is an American environmental organization founded in 1922 that promotes natural resource protection and outdoor recreation.

Although the League's membership declined by the 1960s to a stable level around 50,000, the organization retains a firm base of conservationists and anglers nationwide, with more than 200 chapters across the country.

In the 1940s, the Izaak Walton League of America raised concerns about the pesticide DDT, and played an integral part in protecting the Jackson Hole National Monument from the cattle industry in Teton County.

That program also works with private citizens, local governments and landscape companies to reduce the use of salt as a de-icer on roads, parking lots and sidewalks.

In May 1973, the League sued the U.S. Department of Agriculture over the clearcut logging of Monongahela National Forest in West Virginia as being contrary to the law, which stated in part, "only dead, physically mature, and large growth trees individually marked for cutting" could be sold.
