Table 2 Coefficient values for a linear regression considering the effects of treatment (burned+seeded, burned+unseeded, unburned+unseeded) and time since fire on the difference in sagebrush cover in sagebrush steppe of the Great Basin, USA, between 2011 and 2018, that was estimated by the remotely sensed NLCD (National Land Cover Database) model compared to benchmark field data.The intercept is given as the coefficient estimate for burned+seeded. Tukey’s post-hoc contrasts between different treatment types are given below the regression coefficients. SE standard error
