This Threat-Based Ecostate map (Version 4) provides a spatial depiction of rangeland condition from 2021-2023 across all rangelands throughout the sagebrush biome of the western United States and uses the principles of Threat-Based Land Management (Johnson et al 2019; see https://sageshare.org/) to identify the primary threats to sagebrush ecosystems of the northern Great Basin. Rangeland condition is described by ecological states (ecostates) that express current upland vegetation composition and level of threat from wildfire, invasive annual grasses, and juniper encroachment based on the cover of key rangeland functional groups and the severity of threats present. For more information about this mapping framework, see the Threat-Based Ecostate StoryMap: https://arcg.is/0ufWGv1. |

Ecostate maps were built by the Institute for Natural Resources, Oregon State University, in June 2024 using Esri ArcGIS Pro 3.1.0. Vegetation cover maps used as the basis for this mapping were provided by the Rangeland Analysis Platform (https://rangelands.app/; Allred et al 2021). Citation: Allred, BW, et al. 2021. Improving Landsat predictions of rangeland fractional cover with multitask learning and uncertainty. Methods in Ecology and Evolution. https://doi.org/10.1111/2041-210X.13564. |

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This Threat-Based Ecostate map (Version 4) provides a spatial depiction of rangeland condition over a 3-year average across all rangelands throughout the sagebrush biome of the western United States. The map is based on the principles of Threat-Based Land Management (Johnson et al 2019; see https://sageshare.org/) as a framework to identify and address the primary threats to sagebrush ecosystems of the northern Great Basin. Rangeland condition is described by ecological states (ecostates) that express current upland vegetation composition and level of threat from wildfire, invasive annual grasses, and juniper encroachment based on the cover of key rangeland functional groups and the severity of threats present. Ecostates are determined based on a rolling three-year average of percent cover of annual forbs & grasses (AFG), perennial forbs & grasses (PFG), shrubs, and trees from the Rangeland Analysis Platform vegetation cover products, version 3 (https://rangelands.app/; Allred et al 2021). The rule set used to define each ecostate is provided in the attribute table. This raster covers all rangelands throughout the sagebrush biome. Non-rangeland pixels, including agriculture, barren areas and urban areas are excluded. Pixels are 30m x 30m and projected using WGS 1984.</SPAN></P></DIV></DIV></DIV> |
