Well within a few sentences this author had lost me.Quote:

Been hunting here for about 45 years and have never heard about anything that bad in any part of Canada. I have no fear whitetails will be in any peril in the future, they have been around since dinosaurs and can occupy just about every range across America and Canada.
Article way to alarmist. IMHO
Yes...Quote:

They adapt to their environment but it takes time. It also takes time to mark a shift in trends: ... "30-year time periods are the minimum lengths needed to look for trends possibly indicative of climate change."
I don't know about one big dump, but lots of snow dose kill lots of deer. They can't get to there food and the wolves have a good winter. years ago in WMU 49 we had a really hard winter, the next fall I was hunting along a ridge and came across 13 deer skeletons, they looked like they had just curled up and died. That just me and one ridge, how many other deer died that winter.
One big dump of snow will only really be a factor if it persists on the ground. In Ontario i believe the 50 50 rule is used to predict if it will be a bad winter for the deer. 50 50 rule is a snow depth of 50 cm on the flat in the bush for more than 50 days.Quote:

Google it and read all the abstracts on this topic - eg. modifications to behaviour when summer temps go above 17C, impacts of heat stress for foraging and physical body condition, . increased predation due to behaviour modification, increased winter tick survival due to lack of cold winters. It's a double whammy - hot summers and hot winters are already doing them in.

As you pointed out Moose (and caribou) are already feeling the impacts. The prevalence of winter ticks is another concern as well.Quote:
