Join us in creating an enduring legacy of natural land in northern Illinois. Become a member of the Natural Land Institute. As a member, you will join with others committed to leaving to future generations the uniquely beautiful place that is northern Illinois.

We each have memories of the special places where wild and natural lands spoke to us and changed our lives. When we describe our communities, we always speak of our landscapes. Northern Illinois is a land of prairies, river valleys, endless plains, and upland forests that create a sense of place and identity.

You can help to preserve and enhance that legacy by becoming a member of the Natural Land Institute.

  • The most important benefit of membership is that YOU have a part in saving natural land forever.
  • Members may receive permission to visit our preserves that are not open to the public.
  • Members receive email news updates and early notification of significant natural events
  • Four newsletters per year are mailed to you (Annual Report, fall Land & Nature, Notes from the Field/winter and summer)
  • Receive discounted tickets to events and invitations to Members Only events

Natural Land Institute is a tax exempt organization under section 501(c)(3) of the Internal Revenue Code.

Our natural lands are the most important legacy we can pass on intact to our children and grandchildren. You can help make a difference now and for generations to come!
