I'm out on the following, and for some I have been out for a long time (I don't see myself getting back in at my age):
WY - M, G, S, Bison
CO - M, G, S
MT - M, G
NM - Deer, S
UT - Bison (drew)
OR - everything
ID - M
AK - S, G
When I look at why I bailed, there are many reasons. It's partly because I had my chance and once was enough. It's also an allocation of my budget and what the minuscule likelihood of drawing is. The biggest reason is mostly due to herd numbers declining for every species I have bailed on. And there are declines in some species I've not yet to bail on. That's the big warning sign for me.
Lately, I've spent a lot of time researching the 25-40 year trends of most species across most the states. With the exception of elk, the trend is disturbing. Sheep, Shiras moose, mule deer, pronghorn (in all but NV), mountain goats, showing long-term trends (in most states) that scare the crap out of me. Not because of my need for a tag at this point in my life, but because I want those species to prosper long after I'm gone. That concerns me more than anything we argue about in the offseason.
There's a ton of work to do on the habitat conservation for all those species in all those states, even if I don't hunt them. I find myself in this interesting study of the human behaviors, including my own, as to why I/we seek or apply simple/inexpensive solutions to what are very complex habitat issues. I guess that effort to find the simplest solution is part of the human condition, even if it's as plain as day that the long-term future for hunting and wildlife is in the difficult/expensive work of habitat conservation and improvement; work that requires a decade or two to see the results.
