Both tabular and spatial models were used to predict fire regime departure at the sub-watershed scale (i.e., HUC 10 units). Integrating the fire regime models with predicted changes in climate envelopes provides a clearer understanding of how these ecological systems are likely to respond to multiple stresses. The natural range of variability for each CE was initially derived from LANDFIRE Vegetation Dynamics Development Tool (VDDT) models. The VDDT allows for the development of probabilistic quantitative model of CEs consisting of multiple ecological states with both deterministic and probabilistic drivers. For any defined suite of drivers, the models predict the relative abundance of each state within a defined...

This dataset was derived from 'NatureServe L48 ESLF V2.7'. See process steps for additional information. The dataset represents the work of multiple states and Federal agencies as part of the US Gap Analysis and LandFire programs. Multi-season satellite imagery (Landsat ETM+) from 1999-2001 were used in conjunction with digital elevation model (DEM) derived datasets (e.g. elevation, landform) to model natural and semi-natural vegetation. The minimum mapping unit for this dataset is approximately 1 acre. Landcover classes are drawn from NatureServe's Ecological System concept. Five-hundred and fourty-four land cover classes composed of 12 cultural and 532 Natural/Semi-natural types are described. Land cover classes...

This map summarizes information presented in the other chapters of the report, including background information on the Bureau of Land Management and Rapid Ecoregional Assessments (REAs), and the REA components that are addressed by the Wyoming Basin REA. In addition, we provide two-page summaries for each Change Agent (development, invasive species, fire, and climate change) and Conservation Element (species and communities) assessed by the Wyoming Basin REA. The REA?s provide an assessment of 1) baseline conditions for long-term monitoring of broad-scale conditions and trends; 2) landscape-level intactness of ecological communities, habitats for priority species, and the ecoregion overall; and 3) a predictive capacity...

Freshwater Marsh Ecosystem Integrity - Blueprint 2.0 This layer is part of an older version of the Blueprint. This data represents the Blueprint 2.0 ecosystem integrity scores for the freshwater marsh ecosystem within the South Atlantic LCC geography. To read more about the indicators, please visit the indicator page. Input Data and Mapping Steps Indicators (200 m resolution) were spatially modeled, tested, reviewed, and used as inputs to derive high integrity areas. Please see the indicator folder in the Blueprint 2.0 data gallery for more information about indicator spatial data. The integrity scores for this system are based on indicators within the freshwater marsh and landscapes ecosystem. These indicators...

Maintaining the native prairie lands of the Northern Great Plains (NGP), which provide an important habitat for declining grassland species, requires anticipating the effects of increasing atmospheric carbon dioxide (CO2) concentrations and climate change on the region’s vegetation. Specifically, climate change threatens NGP grasslands by increasing the potential encroachment of native woody species into areas where they were previously only present in minor numbers. This project used a dynamic vegetation model to simulate vegetation type (grassland, shrubland, woodland, and forest) for the NGP for a range of projected future climates and relevant management scenarios. Comparing results of these simulations illustrates...

The UWRM proposal represents the uplands wildlands network in the Heart of the West Proposal. Utah-Wyoming Rocky Mountains Ecoregion (UWRM) core areas and linkages shapefile. This GIS dataset provides core areas and linkages that includes all the components of a three track approach (special elements, representation, and focal species) used during the planning process. This is the result of a study contract by The Nature Conservancy to design an ecoregional plan for Northern Utah, Western Wyoming, Southeastern Idaho, Northwest Colorado and South-central Montana. The study was developed in 2001 by Reed Noss, George Wuerthner, Ken Vance-Borland, and Carlos Carroll from Conservation Science, Inc.

This dataset depicts Ecosystems of Belize - version 2004. This dataset is an update from the 2001 Belize Ecosystems Map (Meerman & Sabido, 2001). This 2004 version has been enhanced using a substantial set of new data. The data quality of the 2004 version has greatly improved over the 2001 version. Marine habitat data were much improved. The classification still follows the UNESCO system developed for the Central American Ecosystems Map and is thus completely consistent with that product. Also, for the first time, metadata are included.

Estuarine ecosystems are controlled by a variety of processes that operate at multiple spatial and temporal scales. Understanding the hierarchical nature of these processes will aid in prioritization of restoration efforts. This hierarchical Columbia River Estuary Ecosystem Classification (henceforth "Classification") of the Columbia River estuary is a spatial database of the tidally-influenced reaches of the lower Columbia River, the tidally affected parts of its tributaries, and the landforms that make up their floodplains for the 230 kilometers between the Pacific Ocean and Bonneville Dam. This work is a collaborative effort between University of Washington School of Aquatic and Fishery Sciences (henceforth "UW"),...
