by an engineer confronted by a forest which has to be removed to permit road construc­ tion. The timber merchant is concerned with the ability of a forest to yield saleable lumber. The interest here is in the size of the larger trunks with some concern for the kinds of trees. At a less destructive level the scientist aims to compre­ hend the forest from many different points of view. The forester himself, in conjunction with the taxonomist, will wish to analyze the floristic composition of the forest and perhaps account for species diversity in an evolutionary time scale (e.g., FEDOROV, 1966; ASHTON, 1969). The evolu­ tionary biologist in his turn may be concerned with repro­ ductive strategies in forest trees (e.g., BAWA, 1974), espe­ cially in a comparative way.
