We have trouble with Birch leaf miners here at our farm. I agree with the factsheet regarding the susceptibility of trees -- those in open areas seem to die from it by the time they are about 15-20 years old. Back in our forest where there are a lot of birch, there seem to be less dying off.

And yes, the invasive species problem is definitely on the rise, partly because of climate change, but also because people are moving around a lot more. In aquatic habitats, a lot of species are being spread by movement of recreational fishing boats as people take boats with livewells from one lake or river to the next. I was just reading about Asiatic Carp in the U.S. They are trying to keep them from getting up as far as the Great Lakes, but they're almost there now. All it will take is a few careless fisherman to move some baitfish up to the lakes and there will be no stopping them after that. It can all be a bit depressing to contemplate sometimes.
