This EnviroAtlas web service supports research and online mapping activities related to EnviroAtlas (https://www.epa.gov/enviroatlas). The Clean and Plentiful Water category in this web service includes layers illustrating the ecosystems and natural resources that filter and regulate water, the need or demand for clean and plentiful water, the impacts associated with water quality, and factors that place stress on water quality and supply. EnviroAtlas allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the conterminous United States. Additional descriptive information about each attribute in this web service is located within each web...

CBR Terrestrial Species Birds Status - Bald Eagle. In addition to current distribution of each bird species, this map shows their current and near-term status within the ecoregion. Current, long-term, and summary bioclimate data is also include for several of these bird species. The input datasets used in the distribution model are also included. 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 fit for the User's intended use. These data may not have the accuracy, resolution, completeness, timeliness, or other characteristics...
Abstrac As a pilot study potential biophysical and human land use drivers in Costa Rica were evaluated using multi-variate statistical methods in a nested scale analysis. The reconstructed land use drivers and their quantified effects on land use were applied within a dynamic framework CLUE (Conversion of Land Use and its Effects) to model land use dynamics in Costa Rica from 1973 to 1984. Our pilot study demonstrates that a land use/cover system can be described as a scale-dependent hierarchical system and that its dynamics can be satisfactorily modelled as functions of biophysical and human drivers.

Although ecosystem service (ES) modeling has progressed rapidly in the last 10-15 years, comparative studies on data and model selection effects have become more common only recently. Such studies have drawn mixed conclusions about whether different data and model choices yield divergent results. In this study we apply inter- and intra-model comparisons to address these questions at national and provincial scales in Rwanda. We compare results of (1) carbon, annual, and seasonal water yield using InVEST and WASSI models, and the above plus the InVEST sediment regulation model using (2) 30- and 300 m resolution data and (3) three different input land cover datasets. For the inter-model comparison, we found the two...

Prioritizing conservation action in the Northern Applachian/Acadian ecoregion is a challenge that can be assessed at the scale of biophysical units (a combination of U.S. Forest Service subsections and Canadian ecodistrict) by assessing the conservaiton irreplaceability of each biophysical unit and comparing this to the threat of land transformation from human development, both today and under future growth scenarios.
