made from tree ashes was exported back to Europe as fertilizer. This left less than one-quarter of original forests remaining. Many forests are now small fragments dissected by fields and roads; these islands of green often differ substantially from the original forests, particularly along the edges. The introduction of exotic diseases continues to be a threat to forest trees, and hence, the forest; examples include the loss of chestnut and elm. At the same time, species such as deer, which are clearing rather than true forest animals, have expanded their range and proliferated in these altered landscapes. Large deer populations have deleterious effects on tree regeneration overall, but particularly for edible species including yew, yellow birch, and hemlock. Deer grazing also has significant negative effects on the number and kind of herbaceous flowering plants.Latham, R. E., J. Beyea, M. Benner, C.A. Dunn, M. A. Fajvan, R.R. Freed, M. Grund, S. B.
