Bull trout population assessment in northeastern Oregon: a template for recovery planning Annual Progress Report for 2006

This report consists of two separate chapters. Chapter 1 describes the results from the monitoring and evaluation of bull trout populations in several streams in northeastern Oregon, which have been monitored annually since 2002. Chapter 2 evaluates the use of mark-recapture methods to monitor bull trout population trends and the trends of different components of these populations, and compares these results with more commonly-used methods. Chapter 2 is a manuscript currently under development and internal review for the journal Transactions of the American Fisheries Society. We request that data or information not be reproduced without permission from the authors.
