Table 2 Density and basal area for understory (0–30 cm in diameter) and overstory (>30 cm in diameter) trees in Sequoia and Kings Canyon National Parks monitoring plots and Yosemite National Park research plots. Mean values are reported with standard error (SE) below in parentheses. Monitoring plots only include trees >1.4 m in height. Note that post-fire tree data was not collected following the 1972 prescribed fire in the research plots.
