About this site
The Eye of Volo Bog is surrounded by concentric, floating vegetation zones. The first zone, the Herb Mat, is the thinnest and only supports light-weight plants like sedges and ferns. As the mat thickens, it supports small shrubs of the Low Shrub Zone then gets thicker still with trees defining the third floating zone, the Tamarack Zone. Each zone is making its way inward and will eventually overtake the eye. For now, Volo Bog is the only open-water quaking bog to remain in Illinois.
