Joe:

I should have added in my previous response to this that 200 year old 
paper birch are common in Upper Michigan and northern MN. So, not only 
are there some new paper birch entering the forest at age 200, but also 
there are some still around from the original disturbance that initiated 
the stand. Paper birch is one of those species that can be both early 
and late successional.
