This book is intended to help us think more sustainably when we evaluate, plant, build, and maintain our landscapes. The watershed approach considers every garden as though it were a mini-watershed, holding on to or cleaning all the water that falls on it and nurturing a diverse habitat of plants and insects. Each mini-watershed can be controlled by the people who steward it. The result is that our collective actions restore our greater watersheds and cities.

This book is organized in a way that will help you change your landscape, whether you do it yourself or work with professionals. You may not be able to do everything at once, so planning is essential.
