Why Map?
• Diagnose the problem• ‘Lookout Towers’ / Early detection• Search & (rescue) destroy• Create inventory: what, where, how much• More efficient use of resources
Weed survey is an important aspect of land health
Choosing a Method
• How large is the area?
• How long will it take?
• How much will it cost?
• Will methods meet the goals?
Hyper-spectral Imaging
• Photo imaging by aircraft• Full coverage• Multiple weeds• Multiple non-weeds• Abundance / Density• GIS layer• Treatment Optimization
– Can reduce treatment cost and increase herbicide efficiency

Treatment Optimization
LAYER 1• Determine cost effective treatment
– Herbicide application method• Aerial• Ground• Spot treatment (foliar)
– Biological• Appropriate site
– Mechanical
Treatment Optimization
LAYER 2• Appropriate Treatment
– Density– Abundance of desirable plants – Proximity to urban area– Other
• customer concern• quantified parameter

Budget:
Phase 1• HSI / Planning 40,000acre $80,000
Phase 2• Treatment 244,200 + herbicide• Monitoring covered / Phase 1• Follow-up treatment minimal
Benefits
• Many uses of remote sensing data
• Treatment optimization
• Most efficient use of resources
• Monitor and measure effectiveness
