Betula alleghaniensis Britton
Yellow birch seedlings often begin on surfaces very different from an intact forest floor. Decaying logs, moss-covered wood, rotten stumps and broken ground provide places where seeds can establish. A continuous layer of fallen hardwood leaves makes survival more difficult. Small disturbances and decomposing wood therefore help shape where the next generation of these forest trees appears.

Botanical name
The cited taxonomic authority accepts Betula alleghaniensis Britton at species rank. Kew POWO: Betula alleghaniensis
Recognizing the plant
Younger trunks show a bronze or silvery-gold sheen, peeling into fine horizontal curls; older bark breaks into darker, scaly plates. Its alternate leaves have pointed tips and doubly toothed edges, turning yellow before they fall. Small winged fruits follow. The contrast between fine papery curls on younger bark and rough plates on older trunks can make different-aged trees look surprisingly unlike one another.
