HAF Implementation Resources
HAF Technical Reference 6710-01

The four landscape scales for assessment described in the HAF TR are listed below. Mid- and fine-scales are to be completed by BLM Interdisciplinary Teams (IDTs) led by BLM state offices in coordination with district and field offices. Site-scale assessments are to be led by district and field offices in coordination with their state office:
- Broad-scale (first-order) is defined by the pre-settlement habitat potential for Greater Sage-grouse and Gunnison sage-grouse.
- Mid-scale (second-order) areas are linked to bird dispersal capabilities in subpopulation and population areas defined by indicators of landscape pattern.
- Fine-scale (third-order) areas encompass the seasonal habitats within the home ranges of sage-grouse.
- Site-scale (fourth-order) areas of seasonal habitats assess the more detailed vegetation indicators of seasonal habitat.
The BLM has operationalized the HAF TR with generalized processes, spreadsheet and report templates, and spatial tools to help state, district, and field offices complete mid-, fine-, and site-scale assessments by end of FY2024 (IM 2022-056). Check out the tabs below for HAF resources
