I find it interesting that the baseline (2003) point is 23 years into a 35-year
graph. If I am interpreting this graph correctly, the only time over the last
23 years that the population has only been at 100% of the baseline or greater
was during the five-year spike (2003-2007). If you the baseline had been taken
from the average population during the first 12 years shown by this graph, the
recent numbers would present a far more abysmal picture.
The chosen baseline of this graph is representative of the sort of "baseline
shift" that Darrel mentioned a few days ago.

I agree. Looks like a decline to me. Thanks, Craig.

Hi All,
Here is the graph that I promised to provide. It shows Oregon's estimated
sage-grouse population beginning in 1980. I don't see how it can be
interpreted in any way except as a decline. This is a fact that Oregon
Department of Fish and Wildlife has never publicly admitted.
