Table 3 Blocked multi-response permutation procedure (MRBP) tests comparing 2008 variables to 2016 variables measured after the 2007 Egley Fire Complex in eastern, Oregon, USA. Boldface P-values denotes significance at the 95% confidence level, whereas boldface A-values are above 0.3 (strong within group agreement), and SE denotes the standard error within each group. NPV = non-photosynthetic (dead or dormant) vegetation; CWD = coarse woody debris

From: Short- and long-term effects of ponderosa pine fuel treatments intersected by the Egley Fire Complex, Oregon, USA
