How will the late-March snowfall and cold weather in the mid-Atlantic and northeast affect the wildlife population in those areas?

I’m assuming that by mid-March, many wildlife species have already begun to adjust for spring – birds, deer, fox, rabbits, etc., that hunker down for the winter have probably already begun to come out.

And then they get hit with another 6–8 inches of snow and freezing temperatures.

Will this affect their fecundity and survivability this summer? Is there likely to be a long term fauna effect as a result of this week’s late-winter-like weather?
