3 Data Flow for List B Annual Regulations
CDA: Online Spatial Database, Shapefiles, Spray Records, GPS Negotiations Annual Rule = Regulation = Management Plans Statewide Maps Contractors Containment Maps Municipalities County Weed Manager Federal Factsheets State Annual rule decisions are driven by data from the field Non-Profit Orgs Local Management Plans Researchers Ag Producers Ag Public Citizen Scientists

4 USGS 7.5’ Quadrangle Map of Vail Pass
Annual Rule Musk Thistle Example USGS 7.5’ Quadrangle Map of Vail Pass 9,000 acres Use annual rule to determine how to manage noxious weeds in the area By county, not by ecoregion

5 Musk thistle Statewide QQ Data 2015 field estimates

6 CDA Online Spatial Database
List B Data CDA Online Spatial Database Application- Flex Database – 2008 Microsoft SQL Server Paper

7 Input/Table Export Acres
Quarter Quad Assignments GIS Acres ≠ Input/Table Export Acres Web App Code Coarse Scale Trends?

8 Annual Regulation List B Data
Assumptions & Caveats: Inaccuracies exist Data is incomplete Over-reporting & under-reporting Not all occurrences are GPS’d What does data tell us about rangelands in colorado Look at list b species- worst offenders & species less common
