It's also a fairly common sight in the news papers with the headlines " Poachers kill,,,,"

Colorado's solution to the mule deer decline is to lower our population objective.
In 2006, the population objective for the units west of I-25 was 583,870 deer. The post-hunt population estimate for those units that year was 579,600.
In 2011, the population objective west of I-25 was 511,300. The post-hunt population estimate was 371,920.
In 2007 there was 31,089 antlerless, 5,324 either-sex and 62,883 buck rifle tags issued for those units (99,296 total).
In 2012 there was 8,863 antlerless, 2,733 either-sex and 37,738 buck rifle tags issued (49,334).
Given the rate tags were issued in 2007 when the population was very near the objective, we will likely see only about 87,000 tags issued in the future, should the population recover to current objective. That is a permanent loss of 12,000 tags in 5 years, blamed primarily on loss of habitat.
And we're about to lose even more to the great landowner tag giveaway

I'd say some of the decline has been because deer were put in people's freezers. Did tag numbers stay similar from 2007-2011? Seeing the population objective reduced is troubling. Does Colorado have data showing what sort of habitat loss has happened in those years? I know you guys had a couple bad winters over there, which years were they?
I will dig up and post some more stuff later tonight, but here are the rifle tag numbers issued the last 6 years. I can't find already-compiled data for archery and ML tag numbers.
2007 - 99,296
2008 - 68,129
2009 - 60,485
2010 - 57,514
2011 - 54,577
2012 - 49,334
Our bad winters were 2007-2008 and 2010-2011.

Those reduced objectives are depressing. Nothing like swinging for the fence, whoa wait, I mean the infield.

My feeling (and maybe this is not correct) is that, if you leave the population objectives where they were at, you are then beholden to sportsmen to do something about it. If you lower the population objectives to match where the population is at, then you can sit back and wait for someone else to fix the problems causing the decline. Granted, there is not much the CPW can do about many of the problems, but I have a concern with them lowering the objectives. Many land management decisions do take into consideration the condition of deer and elk herds, and the potential impacts to those herds. Saying that a herd is at objective or only 5% below objective sounds much better than saying a herd is 50-60% below objective. Thus, you lose the measure of cumulative effects over time.
Notice how infrequently predators are mentioned as the reason for the herd declines above, and yet that seems to be a major focus point for the mule deer conservation organizations.
