sprouting fall seedlings and evading the chipmunk

My little fall greens seedlings are sprouting. No thanks to the chipmunk that dug up several of the pots. Maybe he didn’t find much, maybe I had planted twice what I needed, as it seems I am getting a lot of sprouts anyway. Lettuce, escarole, arugula, bok choy. They will fill in the spaces left by spent spring vegetables. I moved the seedling tray to a safer location that chipmunks can’t get to.
