Index of Ecological Integrity, Stratified by Ecosystem, Version 3.1, Northeast

This dataset depicts the ecological integrity of locations (represented by 30 m grid cells) throughout the northeastern United States based on environmental conditions existing in approximately 2010. Ecological integrity is defined as the ability of an area (e.g., local site or landscape) to sustain important ecological functions over the long term. In particular, the functions include the long-term ability to support biodiversity and the ecosystem processes necessary to sustain biodiversity. The Index of Ecological Integrity (IEI) is expressed on a relative scale (0 to 1) for ecosystems mapped on a modified version of the Northeast Terrestrial Habitat Map developed by the Nature Conservancy and the northeastern states. Ecosystems are the finest scale level of the ecological classification hierarchy. Classes include "Northeastern Interior Pine Barrens" and "Acidic Cliff and Talus".

This ecological integrity dataset is one of a larger set of results developed by the Designing Sustainable Landscapes project led by Professor Kevin McGarigal of UMass Amherst. More information and detailed documentation for the project is available at: http://www.umass.edu/landeco/research/dsl/dsl.html.

Dataset was revised on 11/2015. Version 3.0 was updated using DSLland Version 3.0.

Dataset was updated again on 05/2016. This version was updated using DSLland Version 3.1. The update to DSLland Version 3.1 from Version 3.0 is the addition of a lakes and ponds classification (12 classes based on temperature, depth, and trophic class).
