TY - JOUR T1 - Diversity indexes and interpretation of recreation supply inventories JF - Journal of Soil and Water Conservation SP - 122 LP - 123 VL - 38 IS - 2 AU - Paul R. Saunders AU - G. Wesley Burnett Y1 - 1983/03/01 UR - http://www.jswconline.org/content/38/2/122.abstract N2 - Botanists have established several indexes useful for describing and evaluating diversity. These methods may be used to produce a single statistic describing diversity within recreation supply inventories if types of facilities are equated with species and sites are equated with individuals. Shannon, Simpson, and evenness indexes are experimentally derived for a limited amount of data. The results indicate that the indexes possess considerable analytical power, but are of limited use as planning tools. ER -
