Table 5 Mortality rates for trees within buffered shrub patches of montane chaparral, generalist, and riparian guilds from the pre-fire year (2013) and the immediate post-fire year (May 2014) in the Yosemite Forest Dynamics Plot. Tree mortality rates within buffered shrub patches that differed significantly from mortality rates outside buffered shrub patches are shown in bold (χ2 test; α = 0.005). All significantly different mortality rates were lower within shrub patches than outside. Significant results from pairwise comparisons of tree mortality rates within buffered shrub patches of different guilds are delineated by superscripts (χ2 test; α = 0.0014). Density outside shrub patches was 893.6 trees ha−1 for trees ≤1 cm DBH to <10 cm DBH and 1 475.2 trees ha−1 for all trees.
