Description:

Abstract:

Polygon shapefile that depicts level 3 ecoregions for the Susquehanna River Basin (2006 boundary).  Ecoregions are based on perceived patterns of a combination of causal and integrative factors including land use, land surface form, potential natural vegetation, and soils (Omernik, 1987). This is a copy of the ecoregion coverage of Omernik (1987) with some item names modified.

Purpose:

Dataset developed to fit the needs of the Susquehanna River Basin Commission and is intended for educational display purposes only.

Supplemental_Information:

Reviews_Applied_to_Data. The ecoregions were plotted on a terminal to ensure the EXPORT file was imported properly. No claims are made regarding the accuracy of the original data or linework.

Process_Step:

Process_Description:

Due to changes in the Susquehanna River Basin boundary, this file had to be re-clipped to the 2006 version of the basin boundary.  The coverage "ecorgns" was found on disk 418 of the SRBC library.  This coverage was reprojected to SRBC projection (NAD83 Albers Equal Area Conic) and called ecoregion_repro.shp.  It was brought into ArcMap and verified as the base layer for the original SRBC ecoregion.shp dataset.  Ecoregion_repro.shp was then clipped to the 2006 version of the Basin boundary.

Overview_Description:

Entity_and_Attribute_Overview:

Ecoregions are based on perceived patterns of a combination of causal and integrative factors including land use, land surface form, potential natural vegetation, and soils (Omernik, 1987). There are 76 ecoregions, identified by the item ECOREGION. The item TYPICAL allows a fuzzy logic whereby polygons identified with
TYPICAL = 0 are "most typical" of the ecoregion they represent. Those identified by TYPICAL = 1 are "generally typical" any may not have all the characteristics. The ecoregion coverage is superimposed upon a coverage of states. The state lines may divide polygons.
