Parent Layer: Indexes

Name: Shannon's Diversity Index

Display Field: HU_10_NAME

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Shannon's diversity (SHDIV) - equal to "minus the sum, across all patch types, of the proportional abundance of each patch type multiplied by that proportion. Shannon's index is somewhat more sensitive to rare patch types than Simpson's diversity index." Futher description of these and other class, patch, and landscape metrics can be found online in the Fragstats software documentation file which as of 15 June 2013 was available for download at http://www.umass.edu/landeco/research/fragstats/documents/fragstats_documents.html.
