This dataset was last updated 02/2017. This version includes a new tidal restrictions metric that assesses the effect of undersized culverts and bridges on tidal regime.The previous version (3.1) was updated on 05/2016 by incorporating a revised version of the land cover classification, DSLland Version 3.1, developed by UMass, which included the addition of The Nature Conservancy’s Northeast lakes and ponds classification.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...

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 for aquatic systems.The values for this dataset were extracted from the Index of Ecological Integrity, Region-wide, Version 3.2 for all aquatic systems. Updated 09/2017. The metadata for the original dataset is as follows:This dataset was last updated 02/2017.

These data represent linkages where maintenance or restoration of ecological connectivity is essential for conserving biological diversity within the DRECP area. Current condition of linkages is represented by terrestrial intactness scores at 1km resolution, calculated by version 15a of CBI’s EEMS fuzzy logic model, which integrates multiple measures of landscape development and vegetation intactness.Linkages (which do not include wildland or habitat blocks) include the following:1) Linkages identified by SC Wildlands as part of the California Desert Connectivity Project (http://databasin.org/datasets/85d73316b5ab4816b56ed21787ed78a2). 2) Desert Tortoise TCA habitat linkages, representing least cost pathways...

This dataset was last updated 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.This dataset depicts the ecological integrity of locations (represented by 30 m grid cells) throughout New York State 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...

Conclusions: Summarizes findings from a review of literature intended to identify critical thresholds for conservation based in empirical studies of landscape fragmentation. Presents a conceptual overview of landscape fragmentation and habitat loss, as well as guidelines and thresholds relating to landscape indicators such as patch size, habitat amount, edge effects, riparian buffers, and habitat connectivity. Thresholds/Learnings: Many. See Kennedy et al. 2003. Synopsis: This report summarizes findings from a review of literature intended to identify critical thresholds for conservation based in empirical studies of landscape fragmentation. In presenting a conceptual overview of landscape fragmentation and habitat...
AbstractContext Conservation planning is increasingly using ‘‘coarse filters’’ based on the idea of conserving ‘‘nature’s stage’’. One such approach is based on ecosystems and the concept of ecological integrity, although myriad ways exist to measure ecological integrity.Objectives To describe our ecosystem-based index of ecological integrity (IEI) and its derivative index of ecological impact (ecoImpact), and illustrate their applications for conservation assessment and planning in the northeastern United States.Methods We characterized the biophysical setting of the landscape at the 30 m cell resolution using a parsimonious suite of settings variables. Based on these settings variables and mapped ecosystems, we...

This map depicts the current distribution of terrestrial communities in the Wyoming Basin Rapid Ecoregional Assessment, as determined by LANDFIRE, and bioclimatic conditions suitable for terrestrial biomes developed by Rehfeldt and others (2012). In addition, the potential distribution of bioclimatic conditions suitable for terrestrial biomes in the Wyoming Basin Rapid Ecoregional Assessment as determined by Rehfeldt and others (2012) under projected climate change scenarios. These data are provided by Bureau of Land Management (BLM) "as is" and may contain errors or omissions. The User assumes the entire risk associated with its use of these data and bears all responsibility in determining whether these data are...
