QUANTITATIVE ECOLOQY A N D WOODLAND ECOSYSTEM 183
possess certain unique attributes enabling them to serve as models for
fundamental studies, such as those of Major (1951) and Jenny (1958),
into the interplay of climate, soil and vegetation. The recent peaceful
and martial developments of atomic energy with the mass release of
radioactive material demands a better understanding of the flow of
materials through and out of woodland ecosystems (Olson, 1959) if
man is to survive. Although the problems to be solved in woodland
ecology are so varied and immense, they present ecologists with both a
challenge and a means of demonstrating the practical application of
their subject for the welfare of man.
