In 2005 ODFW reviewed the status of all redband trout populations in the Oregon
portion of the Great Basin. Authors of the
Native Fish
Status Review identified numerous data gaps that prevented
a thorough review of population status and trend. In many cases the assessment was based on one
year of data or speculation.
Prompted by the need for a consistent and continuous dataset The Native Fish Investigations Project
initiated a 6-year pilot study to assess population status of redband trout. Using the
Generalize Random Tessellation Stratified design redband trout abundance
in all 6 interior basins will be assessed every year, starting the summer of 2007. In addition all populations will be
assessed twice (at 3-year intervals) during the course of the study. The results of the study will
allow ODFW to:
- Thoroughly assess population status and trend;
- Provide appropriate management to ensure future fishing opportunities;
- Write effective conservation plans; and
- Assess response of fish populations to changes in climatic conditions.
