This cultural resource indicator is an index of sites on the National Register of Historic Places surrounded by limited urban development. It identifies significant historic places that remain connected to their context in the natural world.Reason for SelectionLow-urban historic landscapes indicate significant cultural landscapes whose cultural context has been less impacted by urban growth. Cultural landscapes are “properties [that] represent the combined works of nature and of man” (UNESCO 2012). Reductions in natural habitat within these cultural landscapes reduce their overall historic and cultural value.Input DataThe National Register of Historic Places reflects what Americans value in their historic built...

Advancing our mechanistic understanding of ecosystem responses to climate change is critical to improve ecological theories, develop predictive models to simulate ecosystem processes, and inform sound policies to manage ecosystems and human activities. Manipulation of temperature in the field, or the “ecosystem warming experiment,” has proved to be a powerful tool to understand ecosystem responses to changes in temperature. No comprehensive synthesis has been conducted since the last one more than 10 years ago. A new synthetic analysis is critically needed to advance our understanding of ecosystem responses to warming, to highlight experimental artifacts and appropriate interpretations, and to guide development...

Tropical forests contain > 50% of the world’s known species (Heywood 1995), 55% of global forest biomass (Pan et al. 2011), and exchange more carbon (C), water and energy with the atmosphere than any other ecosystem type (e.g., Saugier et al. 2001). Despite their importance, there is more uncertainty associated with predictions of how tropical forests will respond to warming than for any other biome (Randerson et al. 2009). This uncertainty is of global concern due to the large quantity of C cycled by these forests and the high potential for biodiversity loss. Given the importance of tropical forests, decision makers and land managers around the globe need increased predictive capacity regarding how tropical forests...

Amphibian populations are declining globally at unprecedented rates but statistically rigorous identification of mechanisms is lacking. Identification of reasons underlying large-scale declines is imperative to plan and implement effective conservation efforts. Most research on amphibian population decline has focused on local populations and local factors. However, the ubiquity of declines across species and landscapes suggests that causal factors at a broader scale are also important. Elucidation of the mechanisms driving population change has lagged, mainly because data have been unavailable at continental scales. We propose to address this need by assembling data to answer questions about broad-scale drivers...

This data set shows forests of North America, classified according to FAO ecological zones (EZ). The data set was created by modifying the Ecological Regions of North America (ecoregions) data included in the North American Atlas. Ecoregion classifications were converted to the FAO EZ classes, based on the Forest Resource Assessment (FRA) 2010, and minor adjustments were made to polygon geometry. In addition, data were added for Hawaii and Puerto Rico, and additional lakes were imported. The FAO ecological zones are based on a combination of climate (temperature and precipitation) and potential vegetation classifications. They are broad areas of relatively homogeneous vegetation, with similar physical characteristics....

This data set shows Level I, II, and III ecological regions (ecoregions) of North America, and is an update and revision of files developed by Canada, Mexico, and the United States of America in the late 1990’s in a cooperative project for the Commission for Environmental Cooperation (CEC). These revised ecological regions were developed in a meeting between representatives of the three nations and CEC in April 2006 in Newport, Oregon. Ecoregions are areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. The ecoregions in this data set are based on the premise that a hierarchy of ecological regions can be identified through the analysis of the patterns and...

A summary data set of all fire polygons we could locate as of December 2007 . We used multiple datasets to developed this layer including data gathered from the internet, publically available databases, and personal contacts with dozens of agency personnel throught the western U.S. Data were assessed for utility (but not accuracy) and formatted for consistency. Each source data set was then attributed consistently with fields for record number and year (of fire). Because various resource management entities map fires somewhat independently (especially in more recent years) we merged overlapping polygons for each year.. Users are encouraged to understand the contents of this data file before using it.
