Fig. 3

Proportion of pixels containing sagebrush according to the National Land Cover Database (NLCD; black line) and corresponding F-statistic from the Chow test that indicates how the temporal trend before each post-fire year differs from the temporal tread after the year (blue line). The red line shows the significance level for the Chow F-statistic; F-statistic values greater than the red line are significant. The maximum F-statistic values in each panel indicate the year when the most change has occurred from before compared to after the year, and thus generally correspond with inflections between the initial post-fire increase in sagebrush followed by a period of stabilization, having little or no directional change in sagebrush from year to year. Values at <0 years since fire are pre-fire conditions. Each panel shows a different fire and treatment (seeded or unseeded) for the areas burned in sagebrush steppe of the Great Basin, USA, that had sagebrush presence and cover measured at least once between 2011 and 2018
