This is an awesome non-profit. It is run by a small group of highly dedicated, knowledgeable, thoughtful people. I think only one person gets paid (the part-time education coordinator who is or recently was a grad student at the local university.) The group has done a beautiful job transforming what was essentially unused and unusable farm land into an incredible nature preserve filled with birds, bugs, fish, animals, native prairie flowers, and oak trees. They work with the high school ecology club, scouting groups, and other volunteers to continually improve the space. It is a stunning, huge area with lots of visitors daily. Middleton is really lucky to have such amazing people helping to beautify the city and improve the quality of life for residents. Love this group. :) *Full disclosure: my mom used to volunteer with them.
