Look for a white barked tree, that'll be silver birch. Take a closer look at the bark and you will see it peels off going around the tree as opposed to going straight up, and the peelings are very papery. You will probably find a stand of them together, they grow fairly quickly I think and they soon take over. The papery bark will light even when wet due to a natural oil in the bark, and it gives of a slightly black oily smoke when it burns. There will be little buds on the tips of the branches, and I think they grow along the sides aswell but I can't quite remember.
There's bound to be an online guide somewhere!!
