But why did you take canda as an example if you talked about so small trees that even norway has in some places? When you talk about canadas trees, it's so large trees that you can build a motorway through them. :huh:
I live in Canada and have as of yet to see a big tree you can drive through.
I'm surrounded by temperate forest where you can find anything from pine, spruce, fir, maple, oak, dogwood, poplar, cedar, just to name a few.

Anyhow I think the trees look good in Skyrim. I like the forests in Oblivion and I'm sure if they can do justice to the trees in Oblivion they'll do a nice job in Skyrim as well.
Skyrim trees will look much better when your playing the game anyhow.
As for the whole 'why is there a huge rotten log and no trees of comparable size' in some Skyrim shot. Big trees die to give way to younger growth and sometimes when in the woods you will come across a huge tree surrounded by smaller ones. Sometimes the bigger trees are rare due to disease and wind storms and old age n stuff.
Maybe the bigger trees in Skyrim collapsed because the cliffracers prefer to nest in them all at once.
Lots of cliffracers and shallow roots + wind storm = bad.
