Schematic diagram of the study's sampling design. The 0.1-ha circular plot contains a nested 0.03-ha circular plot centered on a tree or snag ≥ 25 cm in diameter at breast height. The density and status of trees, shrubs, and snags of different size classes were measured in these plots. The canopy cover was measured at each point every 2 m along the three transects that bisect the plot. The area shaded in darker blue-gray indicates the predetermined 0.067-ha portion from which tree-ring samples were taken to estimate fire severity at plots that burned > 50 years ago
