This dataset includes gravity observations collected on the Coconino Plateau, Arizona, from 2015 to 2019 and reductions that were used to arrive at the gravity residual reported in the associated publication (Wildermuth, 2022). Relative-gravity surveys were carried out using a ZLS Burris relative-gravity meter. Absolute gravity values were taken from the closest NGS stations and relative-gravity differences were combined with nearby absolute gravity values using a least-squared network adjustment, as implemented in the software Gravnet (Hwang, C., Wang, C., Lee, L., 2002. Adjustment of relative gravity measurements using weighted and datum-free constraints. Comput. Geosci. 28, 1005–1015). Additional information...

Cropland conversion is a leading cause of human modification that threatens the ecological function of the sagebrush (Artemisia spp.) biome – the most intact biome remaining in the conterminous United States. However, despite its prevalence relatively little is known about the extent and risk of cropland conversion as well as the landscape scale benefits of easements in combating cropland conversion. Therefore, our goals were to: 1) quantify the cropland area of the sagebrush biome, 2) identify where the highest quality sagebrush rangelands are most at risk to future cropland, and 3) estimate the ecological benefits of conservation easements to adjacent public lands. Our findings show that croplands span over 14.4...

Fire history metrics enable rapidly increasing amounts of burned area data to be collapsed into a handful of data layers that can be used efficiently by diverse stakeholders. In this effort, the U.S. Geological Survey's Landsat Burned Area product was used to identify burned area across CONUS over a 40-year period (1984-2023). The Landsat BA product was consolidated into a suite of annual BA products, which in-turn were used to calculate a series of contemporary fire history metrics (30 m resolution). Fire history metrics included: (1) fire frequency (FRQ), (2) time since last burn (TSLB) and (3) year of last burn (YLB), (4) longest fire-free interval (LFFI), and (5) average fire interval length (FIL). All metrics...
