I was thinking this has been the worst season for deer I have personally seen in Saskatchewan since 2010. Both white tail and mule deer numbers are extremely low and the age structure is heavily skewed on the young side. It is a combination of several extremely cold winters and deep snow coupled with increasingly dry summers and little standing water as well as heavy larval ticks in the falltime and lots of kill around the grain elevators from the ribbon rail meat grinders during the long cold winters and of course record increases in habitat loss and slough draining as farmers race to turn pasture into grain production.
Combine this with white tail being the only open season that doesn't need a draw and you have a bunch of guys hammering any and every white tail they can for a few pounds of meat off a doe or fawn. Shoot the doe and the fawns die. Fawns need their mothers to teach them how to survive through a winter. And we need the does to survive and breed to keep our populations growing.
As for coyotes being a problem, I'm just not seeing that on my 8 trail cams or while I walk several former PFRA pastures. Even coyote numbers are way down. Same with sharp tailed grouse, ruffed grouse and snowshoe hare. I've put on some heavy miles on my boots in some of the best habitat for animals and am seriously concerned with how poor our wildlife populations are. I would say we are in serious trouble right now regarding the state of all of our game species, even migratory birds.
I'd also like to address the growing concern surrounding Chronic Wasting Disease. While I don't think it is close to being a main contributing factor in lowering deer, moose and elk populations it is spreading geographically. Most deer will never even live long enough to die from CWD given that it can take over 2-3 years for symptoms to be fatal after infection. Also, mule deer are primarily the species with the highest incidence of CWD and their populations have largely been afflicted by CWD for decades. Despite this fact, mule deer populations have been stable to slowly growing in some areas notwithstanding swings in population numbers due to other variables like weather and habitat loss and hunting pressure.
