Noxious Weed Mapping

Many of you remember that, not too long ago, quarter-quad mapping data for noxious weeds was drawn on paper maps and mailed to CDA each year. Since those early years, we’ve worked on making continuous improvements to the existing statewide mapping system while keeping it accessible for all users.

The weed mapping data that is collected by counties and other entities is used to help us make species listing decisions, improve plant assessments, inform the public and decision-makers about noxious weed challenges we’re facing, and ensure that updates to management plans in the annual rule are accurate and defensible. We also illustrate management successes and share data with other states to assist with regional Early Detection Rapid Response efforts.

Our current statewide weed mapping system has served us well over the years, but now must be converted from its existing code to new code, or retired. We have decided to set aside the current system and move our mapping data collection to EDDMapSWest, which is a system that is used throughout the western states and which we were early contributors to its initial development. This change is effective immediately, and we will be providing assistance as we make this transition. We’re looking forward to working with you and this new system to continue and improve noxious weed management across the state.
