Table 4 Summary tables describing the minimum, maximum, mean, and standard deviation for several stand level features for each fuel type and treatment status by fuel type: M-1/M-2 Boreal Mixedwood. It should be noted that the number of sampling events for each category is not necessarily the number of sampling events contributing to the computation. For example, a sampling event might not have any deciduous trees and therefore would not contribute to the computation of statistics about the age of deciduous trees. A value of NA indicates that there were zero—or possibly one in the case of standard deviation—sampling events contributing to the computation. Values were rounded to four significant figures, up to four decimal places
