    • Predicted Total and Proportion Grassland Loss (2021-2031)

    Metadata Updated: March 4, 2026

    These rasters represent landscape-scale (i.e., 3.6 x 3.6 km window) predictions of unprotected grassland loss (i.e., grass, shrub, herbaceous wetland cover) from 2021-2031 at 270 m resolution for the contiguous US. Each 270 m pixel value is a grassland loss prediction for the 3.6 x 3.6 km area around the pixel. These were generated by training random forest regression models by relating unprotected grassland loss from 2011-2021 to a suite of covariates from ~2011, and then applying these models to updated surface data ~2021 to make loss predictions for the period of 2021-2031. We developed models for two loss metrics:

    1- Total loss – predictions represent ha unprotected grass loss per 3.6 x 3.6 km area around each pixel

    2- Proportion loss – predictions represent the amount of unprotected grass lost out of what was available to be lost per 3.6 x 3.6 km area around each pixel

    We include models that predict grass loss to cropland or development, as well as grass loss to crop, and grass loss to development, separately. We also include an example of how these and other data can be used to prioritize landscapes for conservation.
