Masters Theses

The Problem: In the Smoky Mountains Pica rubens Sarg. (red spruce) occurs at elevations which suggest that it should occur further south than it does. Whittaker (1956) describes the potential altitudinal range of the spruce-fir forest as being in the southwestern Smoky mountains. High elevation deciduous forest with reduced stature, and "perhaps well beyond their favorable conditions of temperature and growing season," have replaced the sub-alpine forest type. If, as has been suggested by Whittaker (1956) and Mark (1958), historical factors based on changes of climate in geological time have eliminated the red spruce southward, then a modern man-made range …
