From: Long-Term Effects of Burn Season and Frequency on Ponderosa Pine Forest Fuels and Seedlings
Total conifer seedling density (ha−1) for A) ≤0.4 m height, and B) >0.4 m to 1.37 m height, in 2015, one year following spring and fall reburns at 5 yr (three reburns) and 15 yr (one reburn) frequencies in the Blue Mountain Ecoregion, Oregon, USA. Data were natural log transformed for analysis; back-transformed means and 95 % confidence limits are presented. Within height category, treatments with the same letter are not different at α = 0.05. Note breaks in y-axes.
