This dataset represents the Terrestrial Conservation Opportunity Areas identified by the 2015 update to Missouri's State Wildlife Action Plan.
Changes in stream temperature can have significant impacts on water quality and the health and survival of aquatic fish and wildlife. Water managers, planners, and decision makers are in need of scientific data to help them prepare for and adapt to changes and conserve important resources. Scientists are tasked with ensuring that this data is produced in useful formats and is accessible to these stakeholders. In October 2015, project researchers hosted and facilitated a 1.5 day workshop, “Data Storage, Dissemination and Harvesting”, that brought together over 50 stakeholders from state and federal agencies, tribal governments, universities, and non-profit organizations interested in monitoring stream temperature...
The objective of this project is to integrate observations from multiple image acquisition platforms into a coherent time series of glacier volume changes for a variety of sites in the Pacific Northwest, including South Cascade Glacier and the others in Washington State (e.g., Mt. Olympus, Mt. Rainier, Mt. Baker). Specific objectives include: Enhancing glacier mass balance methodology by incorporating newly derived and reanalyzed geodetic records in the form of Digital Elevation Models and associated Area Altitude Distributions. Estimating regional patterns of glacier mass balance by expanding the spatial density of mass balance measurements and the geographic diversity of monitored glaciers. Understanding hydrologic...
Climate change is expected to result in changes in plant-pollinator interactions, but the severity of these changes is not yet clearly understood. This project will address both spatial and temporal effects of climate change on plant-pollinator interactions by studying butterfly and plant phenology in alpine and subalpine environments of Mount Rainier National Park (MORA). Western Washington University and the National Park Service will collaborate on several project objectives, including conducting field work at multiple meadows at MORA to collect plant and butterfly data, constructing plant phenophase profiles for common forbs, constructing butterfly emergence curves for commonly detected species, developing a...
Refinement of Gopher Tortoise Habitat Identification and Related Land Cover Data. The benefits of this project include: 1) much improved gopher tortoise remote habitat identification that could have a strong influence on potential listing status (with the likelihood that significantly more habitat may be identified); 2) better statewide land cover data regarding scrubby flatwoods and potentially refined mesic flatwoods and dry prairie classifications; and 3) potential spin off benefits regarding better habitat identification for related species such as gopher frogs and other xeric adapted species that might be found in on drier flatwoods and dry prairie sites.This raster represents a potential habitat for the Florida...
Native Nations face unique challenges related to climate change, many of which are detailed in recent reports as part of the U.S. National Climate Assessment (Bennett et al. 2014; Hiza Redsteer et al. 2013). Native Americans have a deep connection to the natural environment within which their livelihoods, cultural identity, and spiritual practices are rooted. Changes to hydrologic regimes, landscapes, and ecosystems, in combination with socio-economic and political factors, amplify tribal vulnerabilities to climate change. In the Southwest, tribes are already experiencing a range of impacts that are at least partially related to climate change. They include serious water supply and water quality issues in the...
The Tongass National Forest has identified resources that are important to stakeholders and vulnerable to climate-related stressors. Cooperators will review an action plan and convene a workshop to be held in Southeast Alaska in 2016. The workshop will foster collaboration between scientists, managers, and stakeholders. Workshop goals include: sharing information about climate-related stressors and effects on NPLCC Priority Resources in the Tongass National Forest; developing strategic priorities for improving understanding, reducing risks, and increasing adaptive capacity and resilience; coordinating support for increasing knowledge and informing resource managers

We propose to support the revision and implementation of the South Atlantic Landscape Conservation Cooperative’s Conservation Blueprint by integrating its Ecosystem Indicators into a structured decision support system that makes explicit how the Indicators are interrelated and how these will respond to management and policy interventions aimed at improving the conservation status of the South Atlantic region. Our specific objectives are to (1) develop ecological production functions that predict theecological impacts of selected conservation actions relative to current conditions, and to propagate these impacts through other affected systems or functions; (2) codify protocols for updating and curating geospatial...
We will develop SMART-SLEUTH, an advanced spatially explicit modeling framework designed to augment the current SLEUTH model with sophisticated smart-growth capabilities. Based on the latest version of SLEUTH, we will create an open-source GIS-enabled software package that will implement SMART-SLEUTH with advanced modules and tools for evaluating, predicting, and visualizing smart growth scenarios and outcomes. In this software package, a more user friendly Graphic User Interface (GUI), a multi-level automatic calibration approach built on machine learning algorithms, and new spatial landscape metrics for quantifying land change patterns will provide enhanced support for complex model configuration, calibration,...
The Nature Conservancy (TNC) recently completed an unprecedented assessment of almost 14,000 dams in the Northeastern United States. The Northeast Aquatic Connectivity (NAC) project allows fisheries managers and other interested parties to assess dams at multiple scales based on their potential to benefit anadromous and resident fish species if removed or bypassed. This work has continued, with support from NOAA and USFWS, in the Chesapeake Bay watershed, where data refinements and further analysis have produced a web map and tool that allow users to interactively prioritize dams for mitigation at multiple scales and with varying criteria.The Southeast Aquatic Resources Partnership (SARP) has recently completed...
Version 2.0 Data Viewer for the South Atlantic Create a Version 2.0 Simple Viewer for the South Atlantic Conservation Blueprint that includes updates, additional data (category priorities, actions, justifications, ownership, and partner data), and dynamic charting of indicators and presentation of ecosystem and analysis unit aggregate indicator scores. Continue to refine and improve the South Atlantic Conservation Planning Atlas ( Provide technical guidance and recommendations about how to structure data and future Viewer platforms to achieve specific functions for future versions of the Blueprint hosted within an interactive viewer and the South Atlantic Conservation Planning Atlas.
Native grasslands have been reduced to a fraction of their original extent, with estimated total loss prior to the 1990s of 70% for prairie grassland (Federal Provincial and Territorial Governments of Canada 2010). Conversion of native grassland to cropland and tame hayfields or pasture has been one of the leading drivers of native grassland loss in North America. Degradation of native grasslands also continues in some areas due to changes in natural disturbance regimes such as fire suppression and intensive prolonged cattle grazing, threats from invasive non-native species, fragmentation, intensification of agriculture, and economic development associated with population growth(Federal Provincial and Territorial...
The Crystal Darter (Crystallaria asprella) requires large, clear-water streams with clean sand and gravel bottoms and moderate to swift currents. It is intolerant of siltation and other forms of pollution from various land use practices. Direct habitat degradation from damming, channelization, and dredging has also reduced habitat for this species. Remaining populations have become isolated from one another by dams and impoundments. The Mississippi River most likely no longer serves as a usable corridor for the Crystal Darter because of the silt load. The isolated local populations are then vulnerable to single destructive events such as toxic chemical spills.
Key elements of the 2015 national assessment of stream fish habitats follow the 2010 assessment, including: 1) the idea that distributions and numbers fishes reflect the quality of habitat in which they live; and 2) human landscape factors pose a risk to the condition of stream habitat, and indirectly, to fishes. The 2015 inland stream assessments for the contiguous United States, Alaska, and Hawaii all followed five broad steps (Figure 1) that are described in detail below for the inland stream assessment for Alaska. Note that analytical details for the Alaska assessment differed in southeast Alaska as compared to the remainder of the state (referred to as greater Alaska) due to differences in the resolution of...

Accounting for natural variation With the exception of differences in spatial units, assessments for greater Alaska and southeast Alaska were conducted similarly across regions. Because stream fish assemblage data were not available for the state, no steps were taken to account for natural variation in stream habitats for either southeast or greater Alaska. This represents an important need for future work.

Relative condition of fish habitat in streams of the Pacific Coast States. Histogram shows percentage of total stream length in each condition class.
The Bering Cisco (Coregonus laurettae) is endemic to Alaska and is present primarily along the State’s west and north coasts. It is known to spawn in only three river systems – the Yukon, Kuskokwim, and Susitna Rivers. Genetic research indicates that each of these populations is distinct. The Bering Cisco has been observed to migrate more than 1,200 miles into freshwater streams to spawn. Unlike salmon, some of these fish survive spawning runs. Since this species is slow-growing but short-lived, it is highly vulnerable to alterations in stream flow or water quality and large-scale environmental disasters.
