Adapting Adaptive Management for Testing the Effectiveness of Stream Restoration: An Intensively Monitored Watershed Example

Nicolaas Bouwes, Stephen Bennett, and Joe Wheaton A large effort is underway to test the effectiveness of stream restoration in the Pacific Northwest using intensively monitored watersheds (IMWs) to improve salmonid habitat with the expectation to increase salmonid production (Bennett et al. 2016). How, or whether, stream restoration can improve target salmonid populations and ecosystem functions remains... Read More

What Is the Fate of Amputee Sawfish?

David L. Morgan, Barbara E. Wringer, Mark G. Allen, Brendan C. Ebner, Jeff M. Whitty, Adrian C. Gleiss, and Stephen J.
