This Montana Forest Service grazing leases map is the companion to our BLM grazing allotments map; together they cover nearly all permitted grazing on federal land in Montana. For how Forest Service grazing permits are issued and managed, see the agency’s rangeland management pages.

Click any allotment for its forest, ranger district, head-months, head, active/inactive permit count, GIS acres, and permittee name(s). Toggle between allotment boundaries and clustered centers with the control in the upper right.
