Why #CEJACantWait, in our own words ...

The Environmental Defenders have been around for 50 years! The reason that we’ve been able to keep going and keep working to protect the environment is because of you...our members!!

We want to give a big thank you to anyone who has joined the Defenders as a member over the years, and especially this year. We’re a membership based organization and the time and talents of our members are greatly appreciated.

If you’re not a member and would like to be, visit mcdef.org/members-and-giving (link in bio!), and stay tuned this month for info on all of the benefits membership brings!

Today The Environmental Defenders of McHenry County had a great on-site meeting with Illinois Department of Transportation Region 1 staff about Defenders’ care of the O’Brien Roadside
Prairie. IDOT staff gave us good feedback on the management plan that intern Jacob Karkowski has prepared for the site. We look forward to this continuing partnership!
