Lamarra Dept. of Horticulture Science, University of Minnesota Department of Ecology, University of Minnesota Objective large scale land capability evaluation techniques are needed if man is going to be able to properly plan where development should take place in the landscape. A 6,800 square mile watershed (St. Croix River, Minnesota) was studied using a new technique called "pattern analysis." By correlating drainage densities to soil textures and vegetation, inferences can be made as to the innate ecological diversity and management potential of a watershed. This information should assist the resource manager in recognizing the diversified nature of a major watershed along with which areas in it are best suited for such functions as road building, logging, recreation development, and wildlife management.
