This is a collaborative project between the National Park Service (NPS) and Oregon State University (OSU) for the purpose of studying the genetic connectivity of pika populations in five NPS units. OSU researchers will use individual and population-based genetic analyses to systematically estimate genetic distances among individuals and gene flow among patches or populations in NPS units in two very different habitats (talus vs. lava beds). Genetic distances among individuals or gene flow among groups reflect (in part) the degree that individuals are related and that populations are interacting via dispersal. Thus, researchers will use variation in genetic distance or gene flow to infer how landscapes (e.g., dispersal...

Over 50% of commercial and recreationally important fish species depend on coastal wetlands. In the Pacific Northwest, coastal wetlands, where the ocean meets the land, are highly productive areas that support a wealth of wildlife species from salmon to ducks. The tidal marshes, mudflats, and shallow bays of coastal estuaries link marine, freshwater, and terrestrial habitats and provide economic and recreational benefits to local communities. However, wetlands in this region and elsewhere are threatened by sea-level rise and other climate-related changes. According to a USFWS and NOAA report, between 2004 and 2009, 80,000 acres of wetland were lost on average each year, which is a significant increase from the previous...

This report is published as one of a series of technical inputs to the National Climate Assessment (NCA) 2013 report. The NCA is being conducted under the auspices of the Global Change Research Act of 1990, which requires a report to the President and Congress every four years on the status of climate change science and impacts. The NCA informs the nation about already observed changes, the current status of the climate, and anticipated trends for the future. The NCA report process integrates scientific information from multiple sources and sectors to highlight key findings and significant gaps in our knowledge. Findings from the NCA provide input to federal science priorities and are used by U.S. citizens, communities,...

Coral reefs are seriously threatened by ocean acidification and climate change impacts like coral bleaching. Importantly though, the degree of threat varies for different coral reef areas due to differences in local and regional climate drivers. Climate models are based on the scientific community’s understanding of climate drivers and were used during this project to look forward or ‘project’ conditions in coral reef areas. The projections are global maps that depict changes in acidification and the frequency and severity of the temperature stress events that cause coral bleaching. The project team found that the date by which really severe bleaching is projected to occur annually varies with latitude. Beyond this...

What will the rivers of the Pacific Northwest look like in the future? Will they be stable or unstable? Will the waters be cold and clear or warm and muddy? Will they have salmon or other species? These questions motivated our two-year study of climate warming effects on headwater streams draining the Cascade Mountains. Using a novel combination of snow, geohydrology, and sediment transport models we assessed the vulnerability of stream channels to changing peak streamflow. Our snow modeling shows that with just a 2°C warming, snowfall shifts to rainfall at all elevations, peak snowpacks occur over two months earlier, and snowpacks are reduced by over half of historical values. Our geohydrology modeling shows that...

Climate scientists need more and better information about the needs of decision-makers and managers, while decision-makers need better information about how a changing climate may affect their management and conservation objectives. The goal of this project was to build connections between the Plains and Prairie Potholes Landscape Conservation Cooperative (PPP-LCC), the North Central Climate Science Center (NC CSC), and the National Oceanic and Atmospheric Administration (NOAA) Climate Prediction and Projection Pilot Platform (NCPP) to facilitate a link between the users and producers of climate information, as well as to identify gaps between available and desired data. This project developed a conceptual model...

Water is a key resource in Alaska: Although it comprises 17 percent of the country’s land area, Alaska contains more than 40 percent of the United States’ surface water. Climate changes are anticipated to greatly impact water processes (hydrology), including water temperature and seasonal precipitation patterns and amounts. Understanding the likely impacts of climate change on hydrology is an important first step toward understanding consequent impacts on natural and human communities. The purpose of this project was to assist with the development of a coordinated state-wide approach for monitoring temperature in streams and lakes. This process was guided by the recommendations of a workshop involving hydrologists,...

HawaiÊ»i is home to a rich diversity of native plants, about 90 percent of which are found nowhere else in the world. However, changing climate conditions may reduce the amount of suitable habitat for native plants and contribute to the spread of invasive plant species. The goal of this project was to better understand how Hawaiian native and invasive plants will respond to climate change. Scientists focused on 10 important native and five important invasive plant species, using over 35 years of data from thousands of locations in Hawai‘i to assess the plants’ preferred climate conditions and model their likely best future habitat based on climate change projections. The resulting maps and findings provide an initial...

Although it is certain that climate change will affect the hydrology and biota of Great Plains streams, how and where these effects will be manifested is not known. This project will predict the effects of climate change on these streams by creating watershed hydrology and fish assemblage models that are both linked to watershed characteristics, then predicting changes resulting from climate change using an ensemble of general circulation models. We will identify the areas of primary conservation concern by calculating Index of Biotic Integrity values for 1,600 samples in an existing regional fish database and compare them to the areas that are most likely to experience change under future climate scenarios.

The concept of adaptive management provides a set of good business principles to guide strategic habitat conservation, but these principles are only useful if they are put into practice through a complimentary set of business operations. To that end, if conservation is going to be successful operating at landscape scales, the conservation community must start thinking and functioning like a conservation enterprise. Much more emphasis must be placed on developing and supporting business operations that facilitate the flow of information and other resources at landscape scales. Just like successful national and global businesses, we need to develop an information supply chain to support the communication, coordination,...

After two funding cycles, the Upper Midwest and Great Lakes (UM&GL) Landscape Conservation Cooperative (LCC) decided a more strategic approach was needed to address theconservation priorities of the region. LCC Staff sought a needs assessment that would better highlight the shared priorities and concerns of the conservation community, in addition to helping the LCC find its most effective niche in a region where collaborative conservation is fairly standard practice. This assessment was intended to: • Clarify the most effective role(s) for the LCC in this region• Identify the criteria that would guide the bounds of work undertaken by the LCC • Gather information regarding participant understanding and familiarity...

Priority resources are the set of biological, ecological, and cultural features and ecological processes collaboratively identified as most important or most significant for the focus geography. These resources embody the key components of the Peninsular Florida Landscape Conservation Cooperative (PFLCC) vision, which is a collective vision that reflects the mission, vision, common interests, and values of the focus geography partners. The priority resources are the focus of the PFLCC’s planning, design and implementation of conservation strategies(Benscoter et al. 2015). In Spring 2015, PFLCC’s Steering committee unanimously voted to adopt the SWAP ( the Florida State Wildlife Action Plan) habitats as the basis...

Temperate grassland ecosystems are imperiled globally, and habitat loss in North America has resulted in steepdeclines of endemic songbirds. Commercial livestock grazing is the primary land use in rangelands that supportremaining bird populations. Some conservationists suggest using livestock as “ecosystem engineers” to increasehabitat heterogeneity in rangelands because birds require a spectrum of sparse to dense vegetation cover.However, grazing effects remain poorly understood because local studies have not incorporated broad-scaleenvironmental constraints on herbaceous growth. We surveyed grassland birds across a region spanning26 500 km2 in northeast Montana, United States to assess how distribution and abundance...

Within the time frame of the longevity of tree species, climate change will change faster than the ability of natural tree migration. Migration lags may result in reduced productivity and reduced diversity in forests under current management and climate change. We evaluated the efficacy of planting climate-suitable tree species (CSP), those tree species with current or historic distributions immediately south of a focal landscape, to maintain or increase aboveground biomass, productivity, and species and functional diversity. We modeled forest change with the LANDIS-II forest simulation model for 100 years (2000–2100) at a 2-ha cell resolution and five-year time steps within two landscapes in the Great Lakes region...

This study set out to answer the question: “What data and modeling frameworks are needed to provide scientists reliable, climate-informed, water temperature estimates for freshwater ecosystems that can assist watershed management decision making?” To accomplish this, the study gathered existing stream temperature data, identified data gaps, deployed stream temperature monitoring devices, and developed and tested a stream temperature model that could be regionalized across the Northeast domain. We partnered with another funded project team, led by Jana Stewart at WI USGS to collect data from over 10,000 locations across the climate science center domain. This collection effort aided in identifying data gaps where...

We routinely encounter uncertainty when we make decisions – from picking a new morning coffee to choosing where to live. Even decisions that are supported by science contain some level of remaining uncertainty. In the context of conservation and wildlife management, the potential for uncertainty to influence decisions is perhaps most obvious when we think about predicting how actions (or non-actions) will have lasting impacts into the future. Our abilities to precisely predict future climatic and ecological conditions and determine the exact consequences of our actions are, and will remain, limited. Conservation practitioners and land and wildlife managers must navigate these challenges to make science-informed...
