This book focuses on plant community classification, documenting 45 different ecological communities of plants in the Upper Rio Puerco Watershed, categorized into 11 vegetation series. A combination of landform, vegetation, and soil were considered to be one community. These classifications were implemented in order to predict research results to similar environments and to interpret ecological succession. The approach provided a framework to extrapolate and apply quantitative research results and potential management prescriptions. The research done by the author allowed for development and evaluation of improved management for vegetation, livestock, and wildlife resource of the watershed while improving soil stability and water quality.
