Mapping & Data

The Mapping & Data Committee puts your invasive plant data to work. Our mission is to reduce the costs and increase the effectiveness of invasive species management in the 4-County region through coordinated prioritization, analyses, and communication.

We envision a robust data network made up of CWMA partners and other land managers. Working together, we provide access to invasive species data and maps relevant to invasive species control efforts.

We share information about new technologies and evolving trends in invasive species management. The mapping and data committee promotes data standardization and the use of reliable data collection platforms.

Goals and Objectives:

  • Maintain a forum for information sharing.

  • Increase data contributions.

  • Improve data quality.

  • Increase access to weed distribution maps.

We are working on the following projects:

  • Coordinating priority weed management including data review and map creation.

  • Standardizing data collection across the 4-County CWMA.

  • Promoting invasive species reporting databases like Oregon iMapInvasives, EDDMapS, and other platforms. 

We meet 4-5 times per year and maintain an email list to coordinate our activities. 

Please join us!
