How Wyoming's Burn Permit System Works
Wyoming's fire environment spans dramatic geography — from the high Rockies to eastern grasslands — with very different burning conditions across the state. Western mountain communities face summer-fall fire risk similar to Colorado and Montana. Eastern Wyoming's rangeland has different patterns, with spring grass fires as the primary concern. The State Forestry Division coordinates with National Forests, BLM, and county governments on fire management.
