Utah Bark Beetles and Watersheds Workshop:
Impacts on the Hydrologic Cycle and Water Quality: What have we learned?  

December 1, 2011 - Salt Lake City, UT

 

This workshop was convened by the Western Water Assessment and the US Forest Service Intermountain Region and Rocky Mountain Research Station to explore the water-related impacts of bark beetle infestations in Utah and the Rocky Mountain West.

The goals of the workshop were to:

1) Share key findings and uncertainties from beetle-water research in Colorado and Wyoming
2) Hear from researchers about bark beetle infestations, observed impacts on water, and ongoing studies
3) Seek input from resource managers in Utah about their water/watershed concerns and information needs related to ongoing beetle infestations
4) Help connect decision-makers with researchers and resources
