has anyone notice that they are losing their leaves, around the central u p , all the aspen trees are turn yellow and brown and dropping their leaves, anyone else notice this in their area, its in all type of ground wet land and high land, ???

Could be several reasons. Fungus, insects, and perhaps most likely, high heat. Its fairly common for aspen trees to lose some leaves starting in July/August.

these are the whole tree, looks like late fall, big trees and small

Mine are doing the same. First year i've seen it, also covered in yellowjackets.

Couple yellow/falling leaves. NW WI.

Checked ours out with the dogs this evening, and not seeing it here in the western side.
It does feel like fall though, pretty nice.
