壽命短的落葉喬木樹種，原生於北美洲，分布在加拿大安大略省至新斯科舍省，以及美國賓州、紐澤西州一帶，亦零星散布於印第安納州、維吉尼亞州與北卡羅來納州。喜生長於貧瘠乾燥的山地土壤，但也見於潮濕的混和林地。在荒棄或焚燒過後的土地，灰樺是普遍的先鋒樹種，因而得名「老地樺」。灰樺通常可快速成長到7至9公尺高，樹幹直徑0.3公尺粗。

灰樺(木材)

英文....

Short-lived species of deciduous tree native to North America, ranging from Ontario to Nova Scotia, Pennsylvania, and New Jersey, with disjunct populations in Indiana, Virginia, and North Carolina. It prefers poor, dry upland soils, but is also found in moist mixed woodlands. It is a common pioneer species on abandoned fields and burned areas, thus the name "oldfield birch."Gray birch grows quickly to 7 to 9 m tall and 0.3 m trunk diameter.
