Bull trout 5-year Review and Potential Reclassification 11/27/07 (65 KB pdf)

A brief summary of the science team's activities during the Service's bull trout 5-year review process April 2005 (90 KB pdf).

and a draft "summary of the summary" included in an earlier version of the Conservation Status Assessment (CSA) (July 25, 2006 version) (80KB pdf). Hopefully this will give you a little bit of insight into the workings of the Science Team review

The purpose of the 2 documents below is to show some of the supporting information behind ranking determinations in the Bull Trout Core Area Conservation Status Assessment (CSA).

(1) Introduction to the bull trout core area templates document Feb 2005 - 22 pages (200 kb pdf)

(2) Core area templates themselves Feb 2005 - 668 total pages (1.9 Mb pdf).

....and a bit of fish humor from Jack Ohman to end the topic...
