A twist on our weekly Blooms & Birds walk asthis week we look at the ferns of Grass River Natural Area. Join us on a walk to learn the ferns and flowers from forest to wetland. Along the way we will listen and look for the birds that call Grass River home. Donations are always appreciated. More information at grassriver.org. Grass River Natural Area is located at 6500 Alden Highway, Bellaire MI
