Rangeland ecosystems provide a wide variety of ecosystem services. Some are relatively well quantified and have highly structured markets, while others are poorly defined and lack even rudimentary market opportunities. The highly variable nature of rangelands require a systematic approach to quantifying ecosystem services and assuring both public and private sector markets that prescribe changes in management do indeed result in enhanced outputs of goods and services. We propose the use of Ecological Site Descriptions and State and Transition Models to link ecosystem services to changes in management as a basis for a more transparent markets.
