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...

The SRLCC provided funds to the states of Arizona and New Mexico to support development of the states Crucial Habitat Assessment Tools (CHATs) which provide a decision support system to better incorporate wildlife values, sensitive animals and plants, and important ecosystem features into land use decision-making to reduce conflicts and surprises.Several states have released wildlife mapping tools that are the foundation for displaying crucial wildlife and corridor information. The state and regional CHATs are non-regulatory, and give project planners and the general public access to credible scientific data on a broad scale for use in project analysis, siting and planning. This includes large-scale development...

This dataset shows innundation from the terrestrial ecosystems (reference classification) of South America, Central America, and Mexico. South America: This dataset represents Ecological System patches using various reference datasets. Original data generarated from 2000 era data, modeled in 2005 and updated in 2008 and 2010.Originally, this project developed a GIS modeling approach, using a variety of abiotic and biotic data sets, to produce a map of the distribution of Latin America and Caribbean (LAC) ecological systems throughout South America for use in ecoregional assessments. Ecological systems, defined as spatially co-occuring assemblages of vegetation types sharing a common underlying substrate, ecological...

This dataset was extracted from the terrestrial ecosystems of South America dataset. South America: This dataset represents Ecological System patches using various reference datasets. Original data generarated from 2000 era data, modeled in 2005 and updated in 2008 and 2010.Originally, this project developed a GIS modeling approach, using a variety of abiotic and biotic data sets, to produce a map of the distribution of Latin America and Caribbean (LAC) ecological systems throughout South America for use in ecoregional assessments. Ecological systems, defined as spatially co-occuring assemblages of vegetation types sharing a common underlying substrate, ecological process, or gradient, were identified for all...
Desert grasslands, which are very sensitive to external drivers like climate change, are areas affected by rapid land degradation processes. In many regions of the world the common form of land degradation involves the rapid encroachment of woody plants into desert grasslands. This process, thought to be irreversible and sustained by biophysical feedbacks of global desertification, results in the heterogeneous distribution of vegetation and soil resources. Most of these shrub-grass transition systems at the desert margins are prone to disturbances such as fires, which affect the interactions between ecological, hydrological, and land surface processes. Here we investigate the effect of prescribed fires on the landscape...
