The tree looks crystaline, which fits with the depiction of the pre-Mane Six Elements in the book of legends Twilgiht was reading. It probably isn't really a 'tree' at all but something created by ancient Pony mages. Maybe Nightmare Moon's actions destabilised it and it's taken this 1,000 years for it to weaken so much that the Everfree Forest is out of control and the Celestial Sisters vanish.
