Pine trees can hold their needles for 2-5 or more years, depending on the species. Spruce trees generally hold onto their needles longer than pine trees do, approximately 5-7 years. One evergreen tree that is very noticeable as it loses its leaves in fall is Eastern White Pine.
Razorfen Downs is located in the Barrens far to the south. It is in very near the border to Thousand Needles and along the Eastern edge. It is a mid-size instance for both Alliance and Horde players, although it is located in Horde territory.
Razorfen downs is the lair of Amnennar the Coldbringer, who was a shaman long ago. The Burning Legion transformed him into a Lock of great power. He transferred his allegiance to the Lich King and the Scourge. He has now used his powers to control the Razorfen Downs and the Death's Head Quilboar tribe.
