Birch

Distribution

Birch trees are generally not too large in this pioneer species that can be overgrown by climax species, such as maple. Definitely a northern, cold climate tree, yellow birch is medium sized with a medium diameter although larger trees can grow infrequently. Yellow birch should not be confused with paper birch, which is softer in texture and lighter in color with scattered brown flecks.

Forest Inventory Analysis (FIA) data shows U.S. yellow birch growing stock is 541 million m3, 3.7% of total U.S. hardwood growing stock. American yellow birch is growing 7.09 million m3 per year while the harvest is 4.8 million m3 per year. The net volume (after harvest) is increasing 2.28 million m3 each year. U.S. yellow birch growth exceeds harvest in most of the main producing states including Maine, New Hampshire, New York, Pennsylvania and Vermont.

Birch is available in limited volumes as sawn lumber unselected for color but more limited in sizes and grades if red heartwood or white sapwood is specified. When selected for color FAS grade will allow 5 inch minimum width. Refer to NHLA Grading Rules for color sorting specifications. Birch is more likely to be available in thinner sizes 4/4” (25.4mm) & 5/4” (32mm). Veneer may also be available from specialist suppliers.
