Fig. 7From: Review of fuel treatment effects on fuels, fire behavior and ecological resilience in sagebrush (Artemisia spp.) ecosystems in the Western U.S.Differenced normalized burn ratio (dNBR), an index of burn severity following wildfire, showing increases along a successional gradient from sagebrush to mature juniper in a western juniper and low sagebrush (Juoc/Arar) association as well as a western juniper and mountain big sagebrush (Juoc/Artr) association. Prefire successional stages are as follows: S1 = open sagebrush, S2 = closed sagebrush, and juniper expansion phase P1 = phase I, P2 = phase II, P3 = phase III, and M = Mature juniper.
