how many fawns are you seeing?
I hunt some timber land in 652, no fawns made it past July. I mean NONE!
It's a walkin only area and the timber co never provides access for brush pickers so I'd rule out poaching of fawns being the cause

Never saw any of the deer in this area impacted by DHLS since it became a general concern throughout blacktail range.
Put trail cameras back there for the first time this year. 4+ bears. One is dead already. 180lb. Have another on the camera thats pushing 300lb.
Few of the locals have seen cats in the area too.
Noticed this year that the elk don't have many calves either. Typical amount of bulls have shown up in the area, but the cow numbers are much lower.
In general I would say that several factors are impacting blacktail populations. In some areas its a combination of several factors, in others like where I hunt the cause is specific imho.
