The author of this report was responsible for crosswalking the current National Vegetation Classification to the 1998 Maryland Vegetation Classification (Berdine 1998) and to more recent vegetation classification work in Maryland. This subset report of the International Classification of Ecological Communities (ICEC) reflects vegetation alliances and associations currently attributed to, and those that are potential to Maryland. These data were extracted from The Natural Heritage Central Databases housed by NatureServe. A fully searchable and periodically updated on-line source for the ICEC is at http://www.natureserveexplorer.org. Alliance and association text in this document were adapted from The Natural Heritage Central Databases. In addition, portions of the introductory text describing the classification background, hierarchy, applications, nomenclature and database fields were modified from Weakley et al. (1998) and Weakley et al. (1997). The vegetation alliances and associations presented here represent the Maryland portion of a more comprehensive classification of the terrestrial vegetation of the United States developed by NatureServe and its member programs. NatureServe (formerly called "Association for Biodiversity Information" ("ABI")) is an international organization including NatureServe regional offices, a NatureServe central office, U.S. State Natural Heritage Programs, and Conservation Data Centres (CDC) in Canada and Latin America and the Caribbean.
