Early-Stage Thinning for the Restoration of Young Redwood—Douglas-Fir Forests in Northern Coastal California, USA

Table 1

Mean tree density (stems ha−1), basal area (m2 ha−1), quadratic mean diameter (QMD), and stand density index (SDI) of thinned and unthinned coast redwood—Douglas-fir stands at the Mill Creek Property. Significant differences (*) were determined via two-sample 𝑡 -tests at 𝛼 = 0 . 0 5 .
