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.</p>", "distribution": [{"@type": "dcat:Distribution", "downloadURL": "https://ndownloader.figshare.com/files/61669183", "format": "zip", "mediaType": "application/zip", "title": "Trt_Poly_AgDataCommons.zip"}, {"@type": "dcat:Distribution", "downloadURL": "https://ndownloader.figshare.com/files/61669186", "format": "zip", "mediaType": "application/zip", "title": "TargetPixels_CentroidPts_AgDataCommons.zip"}, {"@type": "dcat:Distribution", "downloadURL": "https://ndownloader.figshare.com/files/61669189", "format": "zip", "mediaType": "application/zip", "title": "ReferencePixels_CentroidPts_AgDataCommons.zip"}, {"@type": "dcat:Distribution", "downloadURL": "https://ndownloader.figshare.com/files/61671280", "format": "csv", "mediaType": "text/csv", "title": "burn_trt_yrs_metadata.csv"}, {"@type": "dcat:Distribution", "downloadURL": "https://ndownloader.figshare.com/files/61671283", "format": "csv", "mediaType": "text/csv", "title": "core_data.csv"}, {"@type": "dcat:Distribution", "downloadURL": "https://ndownloader.figshare.com/files/61671286", "format": "csv", "mediaType": "text/csv", "title": "core_data_metadata.csv"}, {"@type": "dcat:Distribution", "downloadURL": "https://ndownloader.figshare.com/files/61671289", "format": "csv", "mediaType": "text/csv", "title": "burn_trt_yrs.csv"}], "identifier": "10.15482/USDA.ADC/30811058.v1", "keyword": ["bare ground", "crested wheatgrass", "invasive annual grasses", "sagebrush steppe", "shrub", "synthetic control"], "license": "https://creativecommons.org/publicdomain/zero/1.0/", "modified": "2026-03-16", "programCode": ["005:040"], "publisher": {"@type": "org:Organization", "name": "Agricultural Research Service"}, "temporal": "1992-01-01/2023-12-30", "title": "Data from: Variability in vegetation outcomes in widespread post-fire non-native perennial grass seedings associated with site environment and weather"}
