HI,
Letters from county forest preserves have been sent to our club. Several members have received citations when on their own. It isn't a third party unknown person, rather people I know.
Until just recently, Illinois state forests were off limits to mushroomers. More than ten years ago, Lake County had a map outlining where you could hunt for berries, nuts and mushrooms. This changed a few years later, to zero tolerance for collecting mushrooms. I presume the same for nuts and berries, though I don't follow that issue. There is hope the state foresters will influence the counties to relax, though this could be years from now. It is far easier to regulate a no.
Unless I am mistaken, the closest federal forest is Shawnee National Forest situated at the southern tip of Illinois. Illinois state forests are scattered around the state and not very close to Chicago. Kettle Moraine State Park and Illinois State Beach are along the Wisconsin-Illinois border.
I saw this coming long ago. A few times, I represented the club at public events. I had several occasions where forest preserve people questioned about our membership. Specifically what was their use for mushrooms: private consumption or selling. Nothing grates on a forest preserve ranger more than the thought you collected something on public land, then profited from it.
In the northwest, there have been murders over collecting mushrooms on public land that someone believed was their territory. Tents pitched only to claim a collection of mushrooms. Aggressive tactics never seen in Illinois. Do you have anything like that in your region?
Regards,
