Human-induced climate change is increasingly recognized as a fundamental driver of biological processes and patterns, and a threat to the persistence of many species. Recent climate change has already caused shifts in the geographic ranges of myriad species and future climate change is expected to result in even greater redistributions of taxa. As a result, predicting the impact of climate change on future patterns of biodiversity has become a fundamental aspect of conservation planning. Here we use Audubon Christmas Bird Count and North American Breeding Bird Survey data in combination with detailed climate data and projections to estimate the current and future ranges of birds throughout the United States and...
This dataset describes Native American Ceded Tribal lands in Washington State. Boundary lines have been digitized from a variety of digital data sources including 1:100,000 streams for boundaries described in treaties as following a stream or river, 1:24k Water Resource Inventory Areas (WRIA), Watershed Administrative Unit (WAU) and Hydrologic Unit Code (HUC) boundaries for boundaries referred to in treaties as 'divide', 'summit' or 'between the waters of', 1:100,000 Major Public Lands (for current reservation areas), 10 meter DEM and 7.5 minute USGS digital Quad maps (to define ridgelines and 'divide' where WRIA, WAU or HUC boundaries don't exist) and NAIP orthophoto imagery (to get a feel for what a questionable...

Digital orthophotos combine the geometric qualities of a map with the image qualities of a photograph. The orthophotos in this series are a mosaic of digital orthophoto quarter quads (DOQs) produced through the National Digital Ortho Photo Program (NDOP). The image characteristics of the orthophotos in this series follow that of the source DOQs. The ground sample distance is 1 meter in the x direction and 1 meter in the y direction. The images are resampled to 2 meters when an order is placed. The images are rectified to the UTM Coordinate System, NAD83. The images are in JPEG format and each image covers a 7.5-minute quadrangle. The USGS DOQs are replaced by enhanced DOQs from APFO where available. The enhanced...

a. Develop a regional map showing the highest probability pathways of wildfire spread under current conditions.b. Design regional networks of fuel breaks to reduce future wildfire size in large remnant tracts of priority GSG habitat. Networks will be designed by modeling fire spread with fuel breaks using Circuitscape (http://www.Circuitscape.org/), a wildlife connectivity software based on electrical circuit theory applied to a raster map, and consulting with agencies and tribes about regional priority habitats in southern ID and OR, northern NV,and northwestern UT.c. Deliver GIS layers and maps showing suggested networks of fuel breaks to federal and state agencies, and tribes. This will allow fire managers to...

Grasslands comprise a small part of the Chihuahuan Desert but are vital to the biological diversity of the ecoregion. Characteristic grasses of the Chihuahuan Desert are tobosa (Pleuraphis mutica) and black grama (Bouteloua eriopoda) but other common species include alakali sacaton (Sporobolus airoides), big alkali sacaton (S. wrightii), mesa dropseed (S. flexuosus), blue grama (B. gracilis), sideoats grama (B. curtipendula ), hairy grama (B. hirsuta), slender grama (B. filiformis), chino grama (B. brevista), spruce top grama (B. chondrosioides), bush muhly (Muhlenbergia porteri), several three awns (Aristida spp.), and fluff grass (Dasyochloa pulchela) (Johnson 1974, Dinerstein et al. 2000). Many of the sites discussed...

The Desert Renewable Energy Conservation Plan (DRECP), a major component of California's renewable energy planning efforts, will help provide effective protection and conservation of desert ecosystems while allowing for the appropriate development of renewable energy projects. The DRECP is focused on the desert regions and adjacent lands of seven California counties - Imperial, Inyo, Kern, Los Angeles, Riverside, San Bernardino, and San Diego. It is being prepared through an unprecedented collaborative effort between the California Energy Commission, California Department of Fish and Wildlife, the U.S. Bureau of Land Management, and the U.S. Fish and Wildlife Service also known as the Renewable Energy Action Team....

The Pima County Information Technology Department is pleased to introduce PimaMaps, Pima County's next generation web mapping system that will eventually replace the current MapGuide system. The Main MapGuide Map, will remain available for a substantial amount of time while PimaMaps is fully implemented. While MapGuide has been a very reliable web mapping system for many years, it is no longer supported by Autodesk. PimaMaps is based on new technology, provides a more robust and modern interface comparable to Google and Bing, and offers a richer set of functionality beyond what is available with MapGuide. This version of PimaMaps has the following functionality and enhancements that are not available with MapGuide:...
What are current conditions for important park natural resources? What are the critical data and knowledge gaps? What are some of the factors that are influencing park resource conditions? Natural Resource Condition Assessments (NRCAs) evaluate and report on the above for a subset of important natural resources in national park units (hereafter, parks). Focal study resources and indicators are selected on a park-by-park basis, guided by use of structured resource assessment and reporting frameworks. Considerations include park resource setting and enabling legislation (what are this park's most important natural resources?) and presently available data and expertise (what can be evaluated at this time?). In addition...

Natural landscapes in the Southwestern United States are changing. In recent decades, rising temperatures and drought have led to drier conditions, contributed to large-scale ecological impacts, and affected many plant and animal species across the region. The current and future trajectory of climate change underscores the need for managers and conservation professionals to understand the impacts of these patterns on natural resources. In this regional assessment of the Southwest Climate Change Initiative, we evaluate changes in annual average temperatures from 1951–2006 across major habitats and large watersheds and compare these changes to the number of species of conservation concern that are found within these...

MC1 is a widely used dynamic global vegetation model (DGVM) that has been used to simulate potential vegetation shifts in California and Alaska, all of North America, and over the entire globe under various climate change scenarios. However, past simulations were run at a scale that is too coarse (e.g., 10km x 10km for the California simulations) for use by local resource managers, such as those in Yosemite National Park ( see Data Basin feature on Yosemite results ). More recently, the model has been implemented at a finer resolution (800m x 800m) of greater utility to National Park staff. MC1 is a model that simulates vegetation types, ecosystem fluxes of carbon, nitrogen, and water, as well as wildfire occurrence...
