The brown and black standing dead trees are characteristic of burned spruce and birch. B) A view showing the fen to forest transition in an unburned location in the fall. C) A close up of the fen from B. D) The vegetation typical of a bog. This area burned in 1988 and the dense forest in the background is typical of a birch forest.
