NOTE: This download link includes Fish Regions, Freshwater Ecoregions, and Freshwater Resilience. Freshwater ecoregions provide a global biogeographic regionalization of the Earth's freshwater biodiversity. These units are distinguished by patterns of native fish distribution resulting from large-scale geoclimatic processes and evolutionary history. The freshwater ecoregion boundaries generally, though not always, correspond with those of watersheds. Within individual ecoregions there will be turnover of species, such as when moving up or down a river system, but taken as a whole an ecoregion will typically have a distinct evolutionary history and/or suite of ecological processes (Abell et al. 2008). The WWF defined...

This dataset contains measures of seasonal mean bird stopover densities and in seasonal mean bird density based on weather surveillance radar data from 20 radar locations in the Northeast U.S. across seven autumn migrations (15 August through 7 November of 2008-2014) [six autumn migrations for the terminal doppler weather radar (15 August through 7 November of 2009-2014)]. Data are present only in radar-sampled areas for each individual radar (see below for description on how these data are filtered). If you are interested in a continuous map of bird stopover densities for the entire region (and outside of these radar coverage areas), refer to layer “Predicted autumn migratory landbird density, 1km, Northeast U.S.”.The...

Mule deer within the Jackson segment of the Sublette herd winter mainly in the valley and south-facing slopes of the buttes. These geologic features are characteristic of the Jackson Hole area near Jackson, Wyoming. Winter ranges in the Jackson valley are a mixture of national forest public land as well as private urban and exurban land. The lower elevation, south-facing hillslopes are typified by stands of Juniperus scopulorum (Rocky Mountain juniper) or mixed mountain shrub communities of Artemisia tridentata (mountain big sagebrush), Artemisia tripartite (three-tip sagebrush), Purshia tridentata (antelope bitterbrush), Amelanchier alnifolia (Saskatoon serviceberry), Symphoricarpos albus (common snowberry), chokecherry,...

Description: The upper Gila River in New Mexico is one of the few unobstructed rivers in the Colorado River Basin with largely intact native fish populations, including four federally listed and one state listed species.Freshwater systems throughout the West continue to be threatened by human encroachment and water development. Methodologies or decision support tools to evaluate resource management practices that foster an understanding of how fish species adapt to the effects of climate change are critical to future resource management planning.

The project will utilize a 4.5 million acre study area on the Montana Glaciated Plains. The objectives are to (1) identify environmental conditions and management practices that will maintain habitat for grassland birds but not impact ranching sustainability, and (2) identify areas on the landscape that have the greatest conservation potential for grassland birds. This spatial analysis will provide the framework for a rigorous assessment of management actions on the Montana Glaciated Plains.

This project will apply the results of an on-going climate change vulnerability assessment to the management of two complex landscapes. The vulnerability assessment project team will work with mangers, land-owners, and conservation practitioners to explore 1) how downscaled climate datasets, modeled vegetation changes, and information on estimated species sensitivities can be used to develop climate change adaptation strategies, and 2) how model results and datasets can be made more useful for informing the management of species and landscapes. To accomplish these two goals, we will prepare datasets and model outputs for two landscapespotentially, the Pioneer Mountains-Craters of the Moon region in Idaho and the...

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.
A spatial dataset of lands and waters that The Nature Conservancy has a legal interest in (such as a conservation easement or fee-simple ownership). Includes spatial data from TNC's Conservation Lands System (CLS) database, which is the legal database of record for all TNC land transactions (fee, easement, lease and deed restrictions). Conservation Management Status (CMS) is a measure derived from the intent, duration and the effective management potential of spatial features of interest ("conservation situations") in the dataset. It is defined as a measure of the likelihood that an existing conservation situation is sufficient to secure biodiversity and allow for its persistence. For more information about the...

These data are the final landscape permeability data as described in the report "Conserving Nature's Stage: Identifying Resilient Terrestrial Landscapes in the Pacfic Northwest."Permeability refers to the connectivity of a focal cell to its ecological neighborhood when it is viewed as a source; in other words, it asks the question: “to what extent are ecological flows outward from that cell impeded or facilitated by the surrounding landscape?” Thus,permeability starts with a focal cell and looks at the resistance to ecological flow outward in all directions through the local neighborhood. As resistance increases, flow is impeded or stopped altogether. Areas of no resistance allow the flow to proceed until a user-specified...

FY2015The Northwestern Great Basin ecoregion is one of the most intact ecosystems in the west. It is also a biological hotspot for migratory birds, greater sage-grouse and a stronghold for pronghorn antelope. However, altered fire regimes, invasive species, water scarcity, development, and climate change threaten the integrity of this landscape. Several efforts are ongoing for individual species, specific threats or sub-geographies, and over 60 existing plans and assessments have been identified for the region. This project will pull the pieces together to create a holistic view of shared priorities on the landscape.

This dataset represents a clipped version of the terrestrial resiliency index to the State of New York developed by Mark Anderson and associates at The Nature Conservancy (Anderson et al 2012), which is a measure of the relative long-term resiliency of a site based on connectivity to a diversity of landforms, elevations and wetlands. A value of 0.9 in a cell means that it has a resiliency score that is greater than 90% of all the cells of the same geophysical setting in that watershed, and all the cells with >0.9 values comprise the best 10% of all cells across all geophysical settings within the watershed. TNC's resiliency index, as scaled here, is a major component of the terrestrial core area selection index...

We will develop an approach to identify fire refugia in Rocky Mountain ecosystems of the U.S. and Canada then test the function of refugia for biodiversity conservation under current and future climate/fire scenarios. Our products will be designed to inform decision-making in land/easement acquisition, identification of critical areas for maintaining landscape and process connectivity/permeability, and extension of the temporal context for spatial conservation decision making. The approach will be testable for transferability to other locations and ecosystems.FY2013Objectives:The proposed project will provide a science application for focused resource conservation by developing and testing the concept of refugia...

Proposed work will monitor for five years vegetation, fuels, wildlife, insects, and weather at 10 Sagebrush Steppe Treatment Evaluation Project (SageSTEP) sites, all of which have been treated to reduce either juniper encroachment (woodland sites) or cheatgrass invasion (sagebrush/cheatgrass sites). Monitoring of treatment response over the long term will lead to a better understanding of the extent to which managers can manipulate vegetation, fuels, and wildlife habitat in the context of climate change.FY2010Objectives:1) assess longterm trajectories in populations of key plant and animal species, and link these trajectories to management restoration treatments and to climate change; 2) measure total ecosystem...

The Salt and Verde river basins in northeastern Arizona are a vital source of fresh water for the greater Phoenix metropolitan area and for two Native American tribes who rely on the basins’ natural resources for their livelihoods. The region depends on winter rain and snow to replenish the river basins’ water supply. Atmospheric rivers – long, narrow channels in the atmosphere that carry water vapor from the Pacific Ocean – supply a substantial portion of this winter precipitation. While atmospheric rivers are critical for maintaining water resources and preventing drought, they occasionally cause extreme storms that lead to flooding. Scientists project that climate change will affect the intensity and frequency...

The Washington Connected Landscapes Project will provide a framework to address the interacting impacts of habitat fragmentation and climate change on ecological systems and wildlife species within the Great Northern Landscape Conservation Cooperative (GNLCC) boundary.Managing for well-connected landscapes is a key strategy to enhance resilience and ensure the long-term viability of plant and animal populations. However, conservation planning efforts have rarely included connectivity for ecological processes such as dispersal, migration, and gene flow. Connectivity conservation is particularly important in the face of climate change, because many species will require highly permeable, well-connected landscapes not...

The Washington Connected Landscapes Project is a highly leveraged effort to provide scientific analyses and tools necessary to conserve wildlife habitat connectivity. In support of the project, we 1) developed tools necessary to reliably identify and prioritize areas important for connectivity conservation and restoration under current conditions and for allowing species range shifts under climate change; 2) tested and refined these tools by applying them in a Great Northern LCC (GNLCC)-funded effort to identify essential habitats and linkages for the Columbia Plateau Ecoregion where the WHCWG is currently engaged (connectivity and climate tools) and across Washington State (climate tools); and 3) released these...

The South Atlantic Landscape Conservation Cooperative (SALCC) project area supports a wide variety of critical estuarine and marine habitats. However, the existing maps of these resources were created at different scales and are housed in a variety of locations. This can be challenging for users and limits their utility for a regional approach to analysis. Looking across boundaries is important to understanding relative value when making habitat conservation decisions. With this project, The Nature Conservancy (TNC) proposes to: (1) develop a suite of regional natural resource maps for the South Atlantic; (2) create a report describing data source, analytical methods and mapping results that includes a summary of...
