You don't say what frequency you are using.  The higher the frequency, the 
less blockage you can take both because of absorption/reflection and beam 
size.   I will assume you are talking private 23GHz microwave.   23GHz doesn't tolerate foliage at all.

Speaking from experience, never install a link in the fall when you are 
shooting over the tops of bare trees.  You may find in the spring that you 
will have to do a little forestry due to leafing out and growth.   True 
story.
