Buzz,
We've had similar doubts here in Idaho on population estimates. Through outreach to IDF&G, including public records requests, myself and a few others requested a copy of the "model" used to estimate elk numbers. I am a statistician by trade, and I wanted to take a look at their modelling methods from a technical perspective.
Unfortunately, they never provided anything that could be considered at all scientific. It was hard not to be left with the impression that their estimates were SWAG's.
The key metric IDF&G cites here for population health is cow calf ratios, which are determined from samples taken during flights. It seems like a reasonable indicator of health, but I'm not sure an accurate, current population estimate can be derived from it.
There certainly isn't a lot transparency into the estimation methods used here in Idaho. It would be nice if their was. It creates a ton of ill will and suspicion when there isn't.

I'm highly suspect of the elk population estimates in Montana conducted by the MTFWP.
IMO, elk should be managed on OBSERVED numbers, not some population model. Its pretty typical of the MTFWP to say they "flew on a bad day" or "there wasn't enough snow" and determine that there "must have been more elk that we didn't see hiding in the trees"...and any other excuse to over-estimate the population.
After reading some of the crap that was in the shoulder season proposal...I don't put much faith in the MTFWP's ability to manage field mice.
