      <abstract>This is a 30 meter grid that maps upland and wetland wildlife habitats/ecological systems for the Northeastern US, including all 13 states from Maine to Virginia, west to New York, Pennsylvania and West Virginia, and for the Maritime provinces of Canada (Nova Scotia, Prince Edward Island, and New Brunswick) and southeastern Quebec. Mapped habitat types are drawn from the Northeastern Terrestrial Habitat Classification System (NETHCS) and from some ecological system types identifed by Canadian ecologists as being unique to Canada. The NETHCS is based on NatureServe’s Ecological Systems Classification, augmented with additional information from individual state wildlife classifications and other information specific to wildlife managers. A terrestrial ecological system is defined as a mosaic of plant community types that tend to co-occur within landscapes with similar ecological processes, substrates, and/or environmental gradients, in a pattern that repeats itself across landscapes. Systems occur at various scales, from "matrix" forested systems of thousands of hectares to small patch systems, such as cliffs, basin wetlands, or barrens on a particular bedrock type, of a hectare or 2.</abstract>
      <purpose>The purpose of this mapping effort is to provide a common framework and language for conservation planning and wildlife management across jurisdictional borders. Specifically, the NE Terrestrial Habitat Classification System and this map are meant to: provide a standardized and consistent habitat and ecosystem classification at multiple scales across states, provinces, and international borders; facilitate interjurisdictional communication about habitats; offer managers a tool for understanding regional biodiversity patterns; allow for more effective and efficient habitat conservation across the region, including the priortization of habitat conservation activities. The Canada-Northeast Terrestrial Habitat Map was supported by: State Wildlife Grant funding awarded through the Northeast Regional Conservation Needs (RCN) Program, which joins thirteen northeast states, the District of Columbia, and the U.S. Fish and Wildlife Service in a partnership to address landscape-scale, regional wildlife conservation issues; the US Fish &amp; Wildlife Service's North Atlantic Landscape Conservation Cooperative (NALCC); and the US Department of the Interior Northeast Climate Science Center (NECSC).</purpose>

        <attrdef>Macrogroups are broad groupings of similar habitats. They represent a level of the US and Canadian National Vegetation Classifications defined as "combinations of moderately broad sets of diagnostic plant species and diagnostic growth forms that reflect biogeographic differences in composition and sub-continental to regional differences in mesoclimate, geology, substrates, hydrology, and disturbance regimes" (FGDC 2008).  The MACRO_2015 field is a slightly revised version of the MACR2008 field.  MACR_2015 is the field that is used to display the habitat map with the ArcGIS layer file NE-Ca_hab615_macr2015.lyr, which downloads with the grid from the TNC Conservation Gateway web site (http://nature.ly/NEhabitat).</attrdef>

        <attrlabl>HABITAT</attrlabl>
        <attrdef>A classification unit slightly more general than “ECOSYSTEM” (see below), created by combining the ecologic, hydrologic and geographic variants of the ECOSYSTEMs into a broader classification appropriate for many uses.  For example, the HABITAT named “Acidic Cliff and Talus” is composed of 4 geographically separated cliff ECOSYSTEMS (e.g. Cumberland Acidic Cliff and Rockhouse, North-Central Appalachian Acidic Cliff and Talus, etc.).  Likewise, the HABITAT named “Laurentian-Acadian Northern Hardwood Forest” is split into 3 ecological types (high conifer, moist-cool, typic) at the ECOSYSTEM level.  Wetland habitats are often broken out in the ECOSYSTEM field according to their hydrological character – whether they are isolated or associated with a stream, lake, or large river.  Habitat names are usually a combination of a geographic area (such as Laurentian-Acadian) and a descriptive name (Northern Hardwood Forest). Names are based on Gawler (2008) (see the field GAWL2008 below for the original version).  HABITAT is the field that is used to display the habitat map with the ArcGIS layer file NE-Ca_hab615_habitat.lyr, which downloads with the grid from the TNC Conservation Gateway web site (http://nature.ly/NEhabitat).</attrdef>

        <attrlabl>ECOSYSTEM</attrlabl>
        <attrdef>Synonymous with the HABITAT field but may present a finer split of the Habitat; a description of the basis for the finer split is included in the Ecosystem field.  Seven different Ecosystems that fall into the Laurentian-Acadian Wet Meadow-Shrub Swamp Habitat, for example, are split out on the basis of hydrological and regional differences.  In the same way, the Laurentian-Acadian Large River Floodplain habitat is split into six different ecosystems on the basis of the communities within the floodplain: acidic or alkaline coniferous and mixed woods, shrub swamps, marshes, and deciduous floodplain forests.  Ecosystem names are related to the GAWL2008 field described below.  ECOSYSTEM is the field that is used to display the habitat map with the ArcGIS layer file NE-Ca_hab615_ecosystem.lyr, which downloads with the grid from the TNC Conservation Gateway web site (http://nature.ly/NEhabitat).</attrdef>
