    • Data from: Variability in vegetation outcomes in widespread post-fire non-native perennial grass seedings associated with site environment and weather

    Metadata Updated: April 1, 2026

    Crested wheatgrass is widely, and historically, seeded across sagebrush steppe rangelands to increase perennial cover and compete with invasive annual grasses post-fire, however, outcomes vary, likely due to complex combinations of site environmental variables and weather. This study examines variation in vegetation characteristics in post-fire areas associated with crested wheatgrass seeding, and environmental variables, in the northern Great Basin. We selected 142 treatments on Bureau of Land Management lands seeded post-fire with crested wheatgrass over the past two decades in two ecoregions (Snake River Plain, Northern Basin and Range). We selected target 30 m pixels and matched them to 150 reference pixels based on environmental similarity and burn severity within 0.3-3.5 km radius in unseeded areas. We compared change overtime post-seeding in the target pixels to reference pixels with a synthetic control method, comparing pre-fire differences in vegetation between target and reference pixels to post-seeding outcomes. We extracted effect sizes at 5 and 10 years post-fire. We tested for the effects of fire severity, elevation, sand content, and spring precipitation in two time points on seeding effects for each type of cover.
