Bull trout population assessment in northeastern Oregon: a template for recovery planning Annual Progress Report for 2005

This report consists of three separate chapters. Chapter 1 describes results from the monitoring and evaluation of bull trout populations in several streams in northeastern Oregon, which have been monitored annually since 2003. Chapter 2 describes an investigation of the tradeoff between the costs and different levels of precision associated with increasing sampling efforts, given spatial variability and differences in precision across techniques and is a manuscript that currently in review for the journal Conservation Biology as part of Robert Al-Chokhachy's PhD dissertation research, and is currently being revised for publication. Chapter 3 describes an assessment of the movement patterns of subadult bull trout based on both active and passive techniques over the period 2002 – 2005, and is a manuscript in preparation as part of Kristen Homel's MS thesis research.
