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.
