McHarg grounded his theory and methods in the science of ecology and pursued this approach in many projects, including The Woodlands planned community in Texas.

McHarg pioneered the use of map overlays to highlight intrinsic natural features, that commonly included flood zones, wetlands, woody vegetation stands, slopes, drainages, aquifer recharge zones, areas under cultivation and man-made features. He promoted an ecological view, in which the designer becomes very familiar with the area through analysis of soil, climate, hydrology, etc. [3], Design with Nature had its roots in much earlier landscape architecture philosophies.
