Apologies if the photo quality is insufficient. In a particular bit of forest, I found an area with a large birch population that all seemed to be suffering from the same issue. Something is causing the leaves to first stripe green and yellow, then turn brown/black, and while there are new leaf buds forming, trees are seemingly losing the leaves faster than they can replace them. There are other areas with birch trees on the same forest that don't have this issue at all. In the affected area, some trees have only one or two leaves left with any green in them at all.
This is in New England, USA
Yes, because I mostly like to have my services built in a Debian container inside my Proxmox environment. If I'm running it in Docker, there's a good chance it's temporary/PoC, and in that case I do not rebuild or anything, I run it for whatever purpose it serves and then it either goes away or gets migrated to a handcrafted Debian container.
