Relationship between Cutler Mormon-tea [Ephedra cutleri] and Coppice Dunes in Determining Range Trend in Northeastern Arizona

Abstract

Range trend is one of the basic components of rangeland inventories. Understanding the interactions between soil, climatic factors, and vegetation aids the range manager in determining and predicting trend. Coppice dunes, dune interspace, and vegetation were evaluated in northeastern Arizona. Soil with a surface layer of loamy fine sand is susceptible to wind erosion. If Cutler Mormontea is part of the plant community, coppice dunes may form. Range trend can be determined and predicted by observing the status of the coppice dunes, the dune interspace, and their vegetation.
