The Northeast Ecological System dataset was last updated: 7/2014
This dataset represents terrestrial and wetland ecological systems of the Northeast (based on NatureServe’s Ecological Systems Classifications) combined with human-modified land types such as roads and agriculture. Download includes Ecosystem Type, Macrogroup, and Formation, you do not need to download each individually.This dataset was created by substantially modifying The Nature Conservancy’s Northeast Terrestrial Wildlife Habitat Classification System (NETHCS) using these steps:
-Replaced the National Land Cover Database (NLCD) ‘roads’ embedded in the NETHCS with more accurate roads and trains that are distinguished from developed classes
-Removed spurious development (mostly developed open space) from the edges of NLCD ‘roads’
-Added National Hydrography Dataset (NHD) for all lotic and lentic, including high resolution streams, road-stream crossings, and dams-Replaced the single NETHCS open water class with National Wetlands Inventory (NWI) lentic (additional not mapped in NHD), tidal riverine, estuarine, and marine classes-Replaced the single developed and agriculture classes with five developed and two agriculture classes from the 2006 NLCD
-Incorporated 2013 updates to coastal wetlands of the NWI by replacing the NETHCS estuarine classes with the updated NWI estuarine and marine classes.
This dataset was developed as part of the Designing Sustainble Landscapes project led by Professor Kevin McGarigal of UMass Amherst and sponsored by the North Atlantic Landscape Conservation Cooperative (https://www.fws.gov/science/catalog); for more information about the entire project see: http://www.umass.edu/landeco/research/dsl/dsl.html.
The source of this dataset includes: The Nature Conservancy ecological systems map (ESM), National Land Cover Database (NLCD) 2006, Bureau of Transportation Statistics (BTS) roads, TIGER roads 2010 (phase1), Open Street Map roads (phase 2), National Hydrography dataset 1:24k, National Wetlands Inventory (NWI).
