Understory plant cover response to tree canopy cover and the number of times burned throughout the study in the Illilouette Creek basin in Yosemite National Park and Sugarloaf Valley in Kings Canyon National Park, California, USA. Public data were collected beginning in early 1900s. Field data were collected from 2002 to 2013 to observe naturally occurring patterns of forest and understory structure and composition in relationship to fire regime. Understory cover response to burn severity is not depicted because of a small effect size. Curves represent the regression coefficients, shaded areas are the 95% confidence intervals, and dots are the data
