Plant
Gray Birch
Betula populifoliaAlso known as Wire Birch, Poverty Birch, Fire Birch, Oldfield Birch
Gray birch quickly reclaims scorched or cleared ground, thriving in thin, nutrient-poor soils where few other trees survive. Distinctive triangular leaves flutter on slender stems like aspen foliage, catching the slightest breeze above dull, non-peeling grayish-white bark. Because it is short-lived and shade-intolerant, this slender pioneer eventually yields the forest canopy to slower-growing hardwoods and conifers.
