COMMON QUESTIONS

  • The majority of TNC’s preserves in Wisconsin are open to visitors for hiking, canoeing, cross-country skiing, bird watching and photography. A few preserves are generally closed to the public, either due to access or liability problems or because even limited use would destroy the natural features we seek to protect.

    Many Wisconsin nature preserves are ADA accessible. Learn more here.

    You can find descriptions and directions to many of these preserves in the Places We Protect section of this website.

  • TNC provides hunting opportunities for deer, turkey and other game species at most Wisconsin preserves. Learn more here.

  • Yes! We hold stewardship work days at many of our preserves, and we have occasional office or remote volunteer needs. Please check out our volunteer page for more information and upcoming events.

    Feel free to contact us with any questions at WIVolunteer@tnc.org.

  • You can sign up for Wisconsin Great Places News if you want to help us speak up for Wisconsin’s lands, waters and wildlife. You’ll receive news about our work in Wisconsin, and, from time to time, we will send action alerts via Great Places News asking you to contact your Wisconsin legislators to support state and federal policy and funding issues that affect the Wisconsin lands, waters and wildlife you love. If you are interested in taking action for nature beyond Wisconsin, you can visit our Action Center any time.
