在不同温度和水分条件下发育的250~450年生森林群落的总叶面积在20~42 m~2/m~2之间变化。最大的数值出现在中海拔地区，那里冬季积雪堆积，生长季温度凉爽。灌木和草本植物叶面积占总叶面积的3%~14%。对于遇到的大多数物种，都包括了从树叶生物量到表面积的转换方程。
Total leaf area varied from 20 to 42 m2/m2in 250- to 450-year-old forest communities developed under different temperature and moisture conditions. The largest values were in communities at midelevations where winter snowpack accumulated and growing-season temperatures were cool. Shrub and herb leaf area varied from 3% to 14% of the total. Equations for converting from foliage biomass to surface area are included for most species encountered.
