Table 1 Mean (and standard error) stand structure metrics by treatment following the Fire and Fire Surrogate Study’s fuel treatments in 2002 (immediately after treatment) and in 2016 (following the 2005 to 2012 regional mountain pine beetle outbreak). Stand density index was calculated according to Reineke (1933), equivalent to 25.4 cm trees per hectare
