Rangeland Water Quality Conference

February 23 & 24, 2005
Heidrick Ag History Center, 1962 Hays Lane, Woodland CA 95776



Increase knowledge of rangeland water quality issues in California, including management approaches and strategies for implementation.

Conference Flyer (PDF)


  1. Dissemination of new and critical key reference materials to participants.
  2. Provide web-based extension of water quality presentations.
  3. Enhanced understanding of issues and science related to rangeland water quality.

Topic areas will involve a number of presenters with an opportunity for question and answer session at the end of each topic.

Participants will receive 10 Continuing Education Units from the Society for Range Management
