Fig. 1From: Spatial coexistence of American beech and sugar maple regeneration in post-harvest northern hardwood forestsKriged surfaces of sugar maple (a–d) and American beech (e–h) stem densities (stems m−2) at Site 1 by height class and for total stem density. Lighter shades indicate greater stem densities, ranging from 0 to 30 stems m−2. Height classes were h1, 6 to 30 cm; h2, 31 to 90 cm; and h3, 91 cm to <4 cm dbhBack to article page
