Herbicide Use in Forest Management
2006 Fall Program

On June 16, Northwatch's Forest Project hosted a very successful Symposium on Herbicide Use in Forest Management with 13 presenters and over 100 participants. Feedback has been very positive, although there has also been a sense of both "too much" and "not enough" with many participants indicating in their workshop feedback that they would like to hear more about the environmental effects of herbicide application, and more about current research.

Based on that feedback, we developed a followup program to continue the discussion about the use of herbicides in forest management. In addition to the Citizens Guide and a local workshop which will both become available in 2007, the Forest Project  hosted three presentations the fall of 2006, each using a different presentation "technology".

Monday, November 20, 7 pm

Dr. Dean Thompson presented on the potential effects of glyphosate based herbicides on amphibians. The presentation will be made on a tele-conference.
