Betula populifolia (Gray Birch)

A true pioneer species built for the hardest sites on a project, gray birch rapidly colonizes poor, sandy, disturbed ground where few other trees will establish - making it a reliable first-wave species for reclamation and early-successional restoration plantings.

Species Overview

Commonly known as gray birch, Betula populifolia is a fast-growing deciduous tree native to northeastern North America. It typically grows 20 to 30 feet tall with a narrow, pyramidal shape. Gray birch is recognized by its chalky-white bark, which does not peel like other birches, and its triangular, serrated leaves that flutter in the wind. It thrives in poor, sandy soils and is often found in disturbed areas, old fields, and along roadsides.

Application

• Pioneer plantings on disturbed, reclaimed, or poor sandy soils
• Early-successional restoration and reclamation projects
• Roadside and old-field naturalization
• Soil stabilization on difficult, low-fertility sites
