This study analyzes trends in mesic resource productivity in western U.S. rangelands using Landsat data and identifies shifts in drought response and predictors of productivity.

The paper develops NAIP-CHM, a high-resolution canopy height model using NAIP imagery and a U-Net model, achieving high accuracy for ecosystem monitoring.

The paper tests whether excluding fire and grazing reduces annual grass invasion in sagebrush steppe ecosystems, finding that protected areas are still heavily invaded by annual grasses.

The paper estimates rangeland fractional cover and canopy gap classes using Sentinel-2 satellite data for the western United States from 2018 to 2024.
