Bonnie, this is the better   one for our area also but not on the recommended 
list. Due to our heavy clay, birches have a iron chlorosis   problem here.   
I have a huge 3 trunked birch, not Heritage just a species & it is beautiful 
but certainly one of the messiest trees you can have.   My neighbor has 3 in 
their landscape that suffer and look terrible.   They finally removed the worst 
one.   I love the bark!
     The information I rcd yesterday is the Emerald Ash Borer has killed > 15 
million ash trees in Michigan.   Pockets of damaging activity have also been 
found in Illinois, Indiana, Ohio & Windsor Ontario.   In 2005 visual surveys 
were conducted in all 99 counties in Iowa. More than 1300 ash trees in 238 
sites were observed for the signs & sysmptoms of EAB.   Several instances of 
native boring insects were recorded but NO EAB were found.
