About- Green-Rock Audubon Society



Green-Rock Audubon Society, Inc. was incorporated in 1991 as a Section 501 C (3) non-profit corporation and is a local chapter of the National Audubon Society. Between 2000 and 2004 we acquired a conservation easement and 250 acres of land so we are a land trust. In 2007 we began aggressively restoring our property.

Membership Chair: Steve Reischel

Steve grew up on a dairy farm in west-central Wisconsin.  The amount of work and responsibility on the farm limited his world to a small patch of land and a few towns and cities in the surrounding area.  After graduating high school, he went to a technical college and got a degree in electronics technology.  He worked for a few years repairing business machines before taking an information technology job at the University of Wisconsin - Madison and moving his wife and stepchildren to Evansville.  Working at the university broadened his world physically and culturally.  Life on the farm had given him an appreciation for the natural world and he always had a strong interest in science.  Although he wasn’t able to pursue a career in science, he merged the interests of nature and science and began to study birds.  Through volunteer work at a bird banding station he learned how to band birds and quickly earned a banding permit.  He joined Green-Rock Audubon Society about this same time and shortly thereafter was recruited to serve on the Board of Directors. 

Having met several people who traveled internationally, Steve began to travel as well, further expanding his world.  Over the years he has traveled to a number of countries in Central and South America, and the Caribbean.  He developed an interest in photography and uses the opportunity of these trips to document the variety of bird species and the incredible scenery encountered while traveling.  Occasionally he gives presentations about the places he has traveled and the people he’s met.  Nearly every weekend during bird migration you’ll find him banding birds and educating visitors to the bird banding station about birds and nature.
