This dataset describes tree growth and site characteristics for 26 monitoring plots in 3 sites in Redwood National Park in California, USA. One site (A972) was established and sampled in 2007, 2008, and 2013 (Dagley and others, 2023). Two sites (Holter Ridge and Whiskey 40) were established and sampled in 2009 (van Mantgem and Das, 2014). Six existing plots in the Holter Ridge and Whiskey 40 sites were resampled for this study in summer of 2014 and winter of 2015. Tree growth data represent basal area increments at core height. Site characteristics include treatment histories and harvest year. Plot characteristics for the resampled sites are also presented, including location, stand age since harvest, stand age at thinning (if applicable), elevation, slope, plot area, stem density (trees per hectare), and basal area (summed cross-sectional area of live stems per hectare).
