Well, sometimes it is nice to attempt to apply logic to the SW universe and see what we get. You should read Dr. Curtis Saxton's scientific paper that attempts to explain, through a VERY deatailed analysis, why an Endor holocaust would have occured. He explains that, due to the physical properties of the second Death Star and the fact that it was destroyed so close to a moon like Endor, that the fragments from it would have wiped out the ewoks and made the planet unihabitable.
