PHASE I WRAP-UPPHASE I WRAP-UP-- Rangeland Burning on Private Lands – Technical Approach and EI Development
Rangeland Burning Overview
• Quantify rangeland burning on federal, state, and private land
• Develop “strawman” document that defines emission inventory procedure
• Essence: Gather region-wide data for top-down method, fill in specific data where available
• Proof of concept developed during Wyoming statewide agricultural emission inventory
• Need peer review of strawman

Rangeland Activity: Layers
• Top Down– Layer I: Region-wide Data Sources
• Rangeland utilization at county level from 2002 NASS Census• Percent-burned factors and monthly allocation from ETT
– Layer II: Sub-regional Data Sources• Rangeland utilization at county level from individual states
• Bottom Up– Layer III: Summary Burn Activity Data
• Burned acres estimates at county level by month from individual states or districts
– Layer IV: Burn Event-based Activity Databases• Activity inventory of daily burn events from permit/tracking
databases
Rangeland EI Steps
• Collect NASS annual rangeland utilization by county
• Apply most specific percent-burned factor available
• Allocate burn activity to month of year• Allocate monthly subtotals to rangeland burning
events• Assign event to specific day of month• Assign event to specific USGS LCC rangeland
