CNRA: A Brief History
CNRA was founded in 1951 by a small group of citizens concerned about cutting an alley of large hackberry trees during construction of Highway 30 near Oconomowoc. The organization was to be militant in nature, follow the principles of Aldo Leopold, and remain a group of committed conservationists. Its early actions led to designation of the state’s first wilderness area located in the Flambeau State Forest bordering the Flambeau River. Throughout the 1950s its natural roadside vegetative policy served as a guide to highway crews and utilities in their removal of roadside vegetation. Many of Wisconsin’s first conservation laws were shaped by CNRA.
DDT, Wisconsin’s Waterways, Natural Roadsides In the late sixties CNRA brought the Environmental Defense Fund to Wisconsin to fight the neurotoxin DDT. Worldwide expert testimony at a DNR hearing resulted in the declaration of DDT as a pollutant of the state’s waters. Subsequently DDT was banned in Wisconsin and two years later in the U.S. A campaign by CNRA to clean up the Wisconsin River in the 1970s and a special report, Stream of a Thousand Isles: The Wisconsin River, Its History and a Plan for Restoration, were invaluable in spreading the word on the effects of pollution in our waterways. Similar efforts by CNRA related to wetland preservation in the 1980s led to stronger state wetland protection laws. CNRA participated in the successful 40-year fight to protect the Kickapoo River from a dam and speculative development, which threatened an area rich in archeological history and scenic beauty. A 50-year campaign by CNRA for improved roadside management has contributed to reduced mowing, limited herbicide use and increased native vegetation along Wisconsin’s highways.
Horicon Marsh Horicon Marsh has been a special place for CNRA. In 1951 CNRA supported legal action by its president against the Fish and Wildlife Service to exclude hunting on the refuge. Twenty-five years later, in 1976 during the “Goose Wars,” the organization itself sued the managing agencies to prevent dewatering of the marsh. To fight dewatering it established the Horicon Defense Fund derived from sale of Owen Gromme’s print: Requiem Horicon Marsh: 1916-1976. While both suits lost, eventually policies changed to favor CNRA’s positions. Over the years the Horicon Defense Fund has continued to support marsh research, the Marsh Haven Nature Center, and numerous partnerships of agencies. The Fish and Wildlife Service placed CNRA’s publication, CNRA: The First 50 Years, 1951-2001, in its 100-year time capsule buried at Horicon headquarters. In recent years CNRA has joined the fight to protect wildlife and scenic beauty of the marsh from giant wind turbines planned and constructed on its periphery.
CNRA Today Time has changed CNRA. The ecological values once limited to a few individuals and organizations are now widely prevalent. Many different environmental groups are now prepared to act in crisis situations. While CNRA’s mission and organizational structure remain the same as it was almost 60 years ago, its activities today are linked closely to local issues and supporting other conservation organizations.

Ethel Princl Ethel Princl was CNRA treasurer from 1970 to 1991. Because she was in poor health she turned the books over to Charles M. Sturm who has his own accounting firm and volunteers his time to CNRA. Ethel spent her last years in a Wausau nursing home and at age 95 was still requesting minutes and treasurer's reports from CNRA meetings. Read Ethel's article about her activities as CNRA treasurer in CNRA's 50th Anniversary booklet. pg 100. People Places Things
Carla Ochser Kruse Longtime CNRA member passed away on September 24, 2009 at the age of 78. Since springtime meant that the garden could be planted, the songbirds returned, and the woodland flowers would bloom, it was Carla’s favorite time of year. The family held a potluck gathering and celebration of her life May 30, 2010 at the Park Hall on Polk Street in Sauk City. See full obituary, Carla Kruse
