SAK, while DanO' s info is interesting, it says nothing to indicate that the sawtooths would not dominate over native oaks.

You ASSUME the sawtooth is will not be detrimental to the environment, yet like it, because it produces more seed than native oaks??

At tree speed, a 200 year test observation may not be enough time to determine competition effects between sawtooths and native oaks. Yet what we know now is that sawtooths produce the most nuts/seeds..... that should be enough for a logical conclusion.
