Table 5 Comparison of relative mean basal dominance and basal area between burned (n = 60) and unburned (n = 60) plots in Big Basin Redwoods State Park, Boulder Creek, California, USA. Data were collected in 2019 to determine the influence of burns conducted between 1999 and 2011 on vegetation, forest structure, and fuel load. SESE = Sequoia sempervirens, NODE = Notholithocarpos densiflorus, PSME = Pseudotsuga menziesii, ARME = Arbutus menziesii, QU spp. = all Quercus species combined

From: Fuel load, stand structure, and understory species composition following prescribed fire in an old-growth coast redwood (Sequoia sempervirens) forest
