What’s Happening to Calgary’s Birch Trees?

This is the first year that my birch has looked bad and [it has] birch leafminer – haven’t seen that on my tree for years which tells me how stressed it is. Several branches are dead – mainly on the NW side- which took the brunt from a major hailstorm- we were lucky in Airdrie as far as the snowstorm… not too much branch damage but Calgary was devastated.
