Stand structure, biomass production and dynamics of
white spruce (Picea glauca (Moench) Voss) were investigated
in four plantations, ages 4, 10, 18, and 28 years,

Changes in the frost hardiness of balsam poplar (Populus balsamifera L.)
cuttings from four populations along a latitudinal transect from N. Wisconsin to
