EFB is also seen on the blueberry barrens in Maine, but it has been 
associated with blueberries, which are difficult for bees to pollinate.

I have oaks all over our yard and immediate area with no apparent EFB, 
so not sure if there is a correlation. But they leaf out when dandelion 
is at its peak, so not a good data point. Our actual first flow is 
maple, well before oak.
