If it weren’t for fungi, dead trees might not decompose and nutrients would be locked up, unavailable for other plants and animals to use. You can easily find (and make art with) wood-rotting bracket fungi even in winter.
American beech is actually easier to identify in winter than in summer, even at 60 mph, because it holds onto its dead leaves all winter. The reason? The ancestors of beeches evolved in the tropics where plants photosynthesize year-round. Beeches just happened to keep a tight grip on their leaves when they moved north.
