Evaluation of forest adaption scencarios for the Central Hardwood and Gulf Coastal Plains and Ozark Regions

We are working with stakeholders to develop a series of climate change adaptation management strategies for forests in the Central Hardwoods and Gulf Coastal Plains and Ozarks region.  Strategies focus on resistance, resilience, or transition of forests under climate change and vary the types of silvicultural practices considered and where and how much each practice occurs.

Vulnerability assessment and adaptation planning for projected changes in water quality and quantity for protected areas in the Upper Mississippi watershed

Climate change and the extreme weather associated with it can be a major challenge to landowners and land managers interested in the protection, restoration, recovery, and management of wetlands and wildlife habitats. The Midwest is not only experiencing an increase in average temperatures and precipitation, but also an increase in the frequency of extreme events, such as heat, floods, and drought.

Synthesis of current and future risks of climate change to wildlife health and identification of potential mitigation strategies

Changing climate conditions could have significant impacts on wildlife health. Shifts in temperature and precipitation may directly affect the occurrence of disease in fish and wildlife by altering their interactions with pathogens (such as the bacterium that causes Lyme disease), helping vectors like mosquitoes and ticks expand their range, or speeding up the time it takes for a parasite to develop from an egg to an adult. Climate change can also indirectly affect the health of fish and wildlife as their habitats change.

Climate change impacts on erosion, mass wasting, and the supply of sediment to tidal wetlands in the Northeast

Climate change is likely to impact erosion rates, the magnitude and frequency of extreme rainfall/mass wasting events, and the accumulation of sediment in coastal areas. However, long-term rates of erosion and sediment delivery to coastal systems are poorly constrained and there is limited understanding of the relative effects of climate change versus land-use change on these processes.

Bringing Together Cooperative Extension and NE CASC for Climate Adaptation

As more NE CASC projects come to completion, the opportunity to share research-based outputs to an expanded audience of end users has increased. The translation and application of climate science data and products are paramount to effective on-the-ground adaptation.  Extension staff at land-grant universities have a translational role in providing guidance to municipalities, private landowners, farmers, and other practitioners making natural resource management decisions. They work closely with academics, nonprofits, and state agencies to deliver research-based information and approaches.

Relocating Plants for Conservation and Restoration: Developing a Risk Assessment Framework

There is growing interest in the facilitated movement of plants as a means of conserving or restoring species and habitats, as climate conditions and management goals change. For example, plants might be relocated to support pollinator conservation or the restoration of prairies. Some land managers, in an effort to be proactive in the face of changing environmental conditions, are also considering relocating plants to sites that are considered more similar to anticipated future conditions. However, moving plants can be ecologically and economically risky.

Development of the Wildlife Adaptation Menu for Resource Managers

 The Climate Change Response Framework is an example of a collaborative, cross-boundary approach to create a set of tools, partnerships, and actions to support climate-informed conservation and land management. Historically, this effort has focused on the needs of forest managers and forestry professionals. In recent years, however, there has been increasing demand for science and tools to address climate change adaptation in wildlife management and conservation.

Slowing the Flow for Climate Resilience (SFCR): Reducing Vulnerability to Extreme Flows and Providing Multiple Ecological Benefits in a Non-Stationary Climate

Current and future hydrologic variability is a major driver underlying large-scale management and modification of inland waters and river systems. In a climate-altered future, identifying and implementing management actions that mitigate anticipated flow regime extremes will be an important component of climate adaptation strategies. These concerns will be particularly focused on extreme flows (floods and droughts) that have ecological, social, and economic importance, and whose impacts are inversely proportion to their frequency.

Biodiversity Findings and Outreach Impact from National Park Service BioBlitzes

Connecting people, nature, and science is at the core of the mission of the US Department of the Interior. The National Park Service is playing a leading role in that mission in 2016 by hosting a national BioBlitz on May 20-21 that will have people nationwide recording observations of plants and animals in over 100 national parks.

Coupled physical-chemical-biological models to predict losses of cold-water fish from inland lakes under climate warming

Cold-water fish are disappearing from many midwestern lakes as they warm. This loss is due to a combination of de-oxygenation of the deep waters with heating of the surface waters. Together, these climate-driven changes squeeze the depth distribution of fish that require cold, well-oxygenated water, sometimes eliminating their habitat entirely. We will investigate where this combination of factors has likely caused extirpation of cold-water fishes, and where future warming is most likely to eliminate more populations. In addition to hydrodynamic modeling, we are partnering with genomics exp

Predicting the fate and impact of watershed nutrient loads as Lake Michigan's hydrodynamics shift under climate change

Climate change is shifting the hydrodynamics and temperature of both the Great Lakes and their tributary rivers.  Both hydrology and temperature may play potent roles in mediating the magnitude of watershed nutrient load and their fate upon reaching the lake.  Tributary hydrology reflects the source of water (groundwater vs.

Does Variation in Life History and Evolutionary Response Affect Species Vulnerability to Climate Change? Implications for Management

Climate change poses a variety of threats to biodiversity. Most efforts to assess the likely impacts of climate change on biodiversity try to rank species based on their vulnerability under changed environmental conditions. These efforts have generally not considered the ability of organisms to adjust their phenotype to the changing environment. Organisms can do this one of two ways. First, they can adjust their phenotype via non-evolutionary pathways. Second, they can undergo adaptive evolutionary change.

Climate Effects on the Culture and Ecology of Sugar Maple

Maple syrup is produced from the sap of sugar maple trees collected in the late winter and early spring. Native American tribes have collected and boiled down sap for centuries, and the tapping of maple trees is a cultural touchstone for many people in the northeast and Midwest. Because the tapping season is dependent on weather conditions, there is concern about the sustainability of maple sugaring as climate changes throughout the region. In spite of this, maple syrup production is increasing rapidly, with demand rising as more people appreciate this natural sweetener. 

An Integrated Assessment of Lake and Stream Thermal Habitat Under Climate Change

Water temperatures are warming in lakes and streams, resulting in the loss of many native fish. Given clear passage, coldwater stream fishes can take refuge upstream when larger streams become too warm. Likewise, many Midwestern lakes “thermally stratify” resulting in warmer waters on top of deeper, cooler waters. Many of these lakes are connected to threatened streams. To date, assessments of the effects of climate change on fish have mostly ignored lakes, and focused instead on streams.

Pilot Study to Evaluate Coastal Change Using Unmanned Aerial Systems (UAS)

Unmanned Aerial Systems (UAS) are a new and relatively untapped resource for coastal surveying within the USGS and the scientific community, and offer a number of advantages over ground-based surveys and manned aerial systems, including the ability to rapidly deploy and efficiently collect remote sensing data and derive high-resolution elevations over variable terrain. The project provided a low-risk, low-cost means to explore the utility of UAS for coastal mapping on beaches and marshes, and developed methodology and capacity to acquire, process, and analyze data.

Characterizing Local and Rangewide Variation in Demography and Adaptive Capacity of a Forest Indicator Species

Climate change will have sweeping impacts across the northeast, yet there are key gaps in our understanding about whether species will be able to adapt to this changing environment. This project illuminated local and region-wide changes in forest ecosystems by studying the red-backed salamander, a species that is a strong indicator of forest conditions. This study identified habitat and forest characteristics that improve the resiliency of forest dwelling amphibians and other wildlife to climate change.

Using Scenario Planning to Inform Land and Wildlife Management: A Pilot Project for Boreal Forests in the Northeastern United States

Scenario planning is one decision support method that can help managers incorporate information about future changes in climate and other drivers into their management decisions. The development of future scenarios (of climate change, socioeconomic conditions, land use changes, and ecological responses) can help state and federal managers understand plausible ecological futures, vulnerabilities, and opportunities as a result of climate change and related stressors.

Massachusetts Fish and Wildlife Climate Action Tool

The Massachusetts Wildlife Climate Action Tool is designed to inform and inspire local action to protect the Commonwealth’s natural resources in a changing climate. This Tool focuses on providing information for a range of local decision-makers, including conservation practitioners, landowners, municipal agencies, and community leaders, seeking to conduct on-the-ground climate change adaptation efforts.

With this tool, users can:

Using agent-based models to identify conservation solutions to large scale environmental variation and climate change

Effective migratory bird management and conservation requires an integrate approach at multiple spatial and temporal scales.  We developed a spatially explicit agent-based model for dabbling ducks during spring migration. We are modeling foraging and resting behavior at prominent spring migration stopover sites throughout the midcontinent region.  Emergent properties of the working model include spring migration stopover duration, movement distances and survival.

Incorporating social drivers to optimize conservation practices that address Gulf Hypoxia and declining wildlife populations impacted by extreme climate events

USFWS Landscape Conservation Cooperatives (LCCs) throughout the Mississippi River Basin (MRB) have identified high nutrient runoff, a major contributor to Gulf hypoxia, and declines in wildlife populations (especially grassland and riparian birds), as conservation challenges requiring collaborative action. This project developed a spatial decision support system (DSS) to address these issues.

Avian indicators of climate change based on the North American Breeding Bird Survey

Appropriate ecological indicators of climate change can be used to measure concurrent changes in ecological systems, inform management decisions, and potentially to project the consequences of climate change. However, many of the available indicators for North American birds do not account for imperfect observation. We propose to use correlated-detection occupancy models to develop indicators from the North American Breeding Bird Survey data. The indicators will be used to test hypotheses regarding changes in range and distribution of breeding birds.

Science to inform management of floodplain conservation lands under non-stationary conditions

Recent extreme floods on the Mississippi and Missouri Rivers have motivated expansion of floodplain conservation lands. Within Missouri there are more than 85,000 acres of public conservation lands in large-river floodplains. Floodplain lands are highly dynamic and challenging to manage, particularly as future climatic conditions may be highly variable.

Development of Dynamically-Based 21st Century Projections of Snow, Lake Ice, and Winter Severity for the Great Lakes Basin to Guide Wildlife-Based Adaptation Planning, with Emphasis on Deer and Waterfowl

Our project focused on anticipated effects of 21st century climate change on winter severity, snowpack, and lake ice across the Great Lakes Basin and the response of wildlife populations, namely white-tailed deer and dabbling ducks. Winter conditions have changed substantially since the mid-20th century, with rising temperatures, declining lake ice cover, and increased lake-effect snowfall. Nonetheless, due coarse resolution, poor lake representation, and insufficient treatment of lake-effect processes in global climate models, basinwide climate change projections remain uncertain.

Assessment of paleoclimate resources for studies of climate extremes

This project focused on compiling existing paleo-limnological data from lakes throughout the Northeast. The goal of this project was to create an editable database of existing chronologies and proxy data. This resource can then be accessed and added to by any paleo-limnologists working in the region. Based on the existing information, researchers will be able to identify "high-reward" lakes that may be targeted for future high-resolution paleoclimate analysis and also pinpoint regions of the Northeast that may be currently lacking sufficient paleo-limnological data.

Effects of small impoundments on stream temperature regimes in the context of a changing climate

Small dams and impoundments are ubiquitous in stream networks in the northeastern and north central US.  Concerns about their effects on stream fish population connectivity and their risks to human infrastructure and safety have prompted efforts to remove many of these dams.  Dams also have  potentially significant impacts on stream thermal regimes, and as a consequence their removal may either ameliorate or exacerbate effects of increasing air temperatures.  Also, given their ubiquity, temperature modeling and monitoring efforts need to account for the effects of small impoundments for ass

Understanding Conservation Management Decisions in the Face of Sea-Level Rise Along the U.S. Atlantic Coast

This project addresses a complex local scale conservation problem: managing the impacts associated with sea level rise and coastal flooding on migratory waterbirds and their habitat.  Decisions made by a conservation manager are complicated by three elements that can be expected to occur in almost any of these management situations.  Interactions among dynamic physical and biological processes affect both waterbirds and their habitat and food resources; these processes operate at local to flyway scales and are challenging to represent and analyze.

NorEaST – Stream Temperature Web Portal Demonstration and Application

Climate change is expected to alter stream temperature and flow regimes over the coming decades, and in turn influence distributions of aquatic species in those freshwater ecosystems. To better anticipate these changes, there is a need to compile both short- and long-term stream temperature data for managers to gain an understanding of baseline conditions, historic trends, and future projections. Unfortunately, many agencies lack sufficient resources to compile, QA/QC, and make accessible stream temperature data collected through routine monitoring.

Fitting the Climate Lens to Grassland Bird Conservation: Assessing Climate Change Vulnerability Using Demographically-Informed Species Distribution Models

Our goal was to develop a framework to identify demographic sensitivities and assess the vulnerability of grassland bird species to future climate change. To do so, we developed a strong partnership among managers and researchers to understand how climate change might impact the conservation and management planning of grassland birds throughout the NE CASC region and identify potentially vulnerable species. Using input from managers, we focused our efforts on two grassland indicator species of high conservation interest: Henslow’s Sparrows and Bobolinks.

A Decisions Support Mapper for Conserving Stream Fish Habitats of the NE CASC Region

To integrate results of a current condition habitat assessment of stream habitats that accounts for fish response to human land use, water quality impairment, and fragmentation by dams with estimates of future stream habitats that may change with climate.  This was accomplished by 1) Characterization of the current condition of stream fish habitats throughout the NE CASC region based on responses of target fish species to a diverse set of landscape-scale disturbances; 2) Identification of stream reaches predicted to change with climate and likely to change distributions of target fish speci

Making decisions in complex landscapes: headwater stream management across multiple agencies

There is growing evidence that headwater stream ecosystems are especially vulnerable to changing climate and land use, but their conservation is challenged by the need to address the threats at a landscape scale, often through coordination with multiple management agencies and landowners. This project sought to provide an example of cooperative landscape decision-making by addressing the conservation of headwater stream ecosystems in the face of climate change at the watershed scale.

Modeling effects of climate change on spruce-fir forest ecosystems and associated priority bird populations

Eastern spruce-fir forest ecosystems are among the most vulnerable to climate change within the continuous US. The goal of this project was to develop tools to identify refugia sites most likely to support spruce-fir forest and its associated high-priority obligate spruce-fir bird species over the long-term under projected climate change scenarios.

Circulation patterns associated with climate extremes

The variability of winter precipitation over the northeastern United States and the corresponding teleconnections with five dominant large scale modes of climate variability (Atlantic Multi-decadal Oscillation, AMO, North Atlantic Oscillation, NAO, Pacific-North American pattern, PNA, Pacific Decadal Oscillation, PDO, and El Niño–Southern Oscillation, ENSO) were systemically analyzed in this study.  Three leading patterns of winter precipitation were first generated by empirical orthogonal function (EOF) analysis.

Sea Level Rise and Its Impacts

A reconnaissance study distinguishes coastal areas of the northeastern U.S. (approx. Virginia to Maine) that will experience an inundation-dominated response to sea-level rise from those that will respond dynamically due to physical and bio-physical sedimentation and erosion processes. Areas that will be dominated by inundation include urban regions of intense development and/or coastal engineering, as well as bedrock coasts. Areas that will respond dynamically include beaches, unconsolidated cliffs, barrier islands, and wetlands.

Ecology of coastal migratory striped bass (Morone saxatalis)

Striped bass are a priority species for the Northeast LCC.  Subadult and small adult (375–475 mm total length) striped bass Morone saxatilis are abundant in northern estuaries during the spring through late fall.  However, little is known about how this important marine fish migrate among estuaries and use salt marshes as foraging areas.  This project assesses the migratory pathways of striped bass and is developing a quantitative understanding of diet and habitat use.

Predicting fire frequency with chemistry and climate

This project developed a predictive model for estimating fire frequency based on theories and data in physical chemistry, ecosystem ecology, and climatology.  We applied this model to produce maps of fire frequency under current climate and several climate warming scenarios across the United States.  Results of the project provide information on fire frequency under alternative climate scenarios, information needed to parameterize forest landscape change models.

Stream temperatures in the Driftless Area

The Driftless Region is blessed with an exceptional coldwater fishery (native brook trout and non-native brown trout).  Based on statistical modeling, it has been predicted that over the next 50 years brook trout will virtually disappear from the region and areal extent of brown trout will decrease significantly.  However, these predictions do not account for potentially significant increases in groundwater recharge and hence in baseflow as a result of likely increases in fall through spring precipitation and potential decreases in winter frost.  Nor do they account for the fact that basefl

Effects of climate, disturbance, and management on the growth and dynamics of temperate and sub-boreal forest ecosystems within the Lake States and New England

This project is using a combination of long-term data records and recently established large-scale adaptive management studies in managed forests across the Lake States, New England, Intermountain West, and Black Hills to identify forest management strategies and forest conditions that confer the greatest levels of resistance and resilience to past and emerging stressors and their relevance in addressing future global change.  This work represents a broad partnership between scientists from the USFS Northern Research Station, USFS Rocky Mountain Research Station, USGS, University of MN,  Un

Downscaling of GCM output; studies of climate extremes

A statistical downscaling method (bias-correction and spatial disaggregation: BCSD) is applied to general circulation models (GCMs) from the Coupled Model Intercomparison Project Phase 5 (CMIP5) to generate high-resolution downscaled precipitation, maximum temperature, and minimum temperature estimates under historical and three future emission scenarios over the Northeastern United States.

Assessment of regional climate model simulation estimates over the northeast United States

We used outputs from an ensemble of regional climate models (RCMs) participating in the North American Regional Climate Change Assessment Program (NARCCAP) to investigate potential changes in seasonal air temperature and precipitation between present (1971–2000) and future (2041–2070) time periods across the northeast United States (New England and adjacent states).

Evaluating the impacts of climate change in the Connecticut River Basin

For the past four years, The Nature Conservancy (TNC) and the US Army Corps of Engineers (Corps) have funded a study at UMass to evaluate the impacts of climate change on the biological resources in river and to investigate how the negative impacts of reservoir regulation could be ameliorated in the face of climate change.  It is fortuitous that this study provides an excellent basis for future “watershed” type studies that may be performed by the NE CASC. The study has resulted in a full calibrated hydrology model of the Connecticut River Basin, a set of 112 different future hydrology scenarios associated with climate change, and a simulation and optimization model of the major reservoirs in the basin.

 

Effects of hydrologic change and variability on upstream limits of stream fish distribution

Coldwater stream fishes are widely predicted to move upstream in response to warming downstream river temperatures.  However, in the process they may encounter upstream limits, which are likely to be exacerbated by increased hydrologic variability if upstream locations draining small basins switch from perennial to ephemeral flow, with important but currently unknown implications for coldwater habitat and stream fish populations.  In this project, we will look at the current determinants of upstream limitation for Eastern Brook Trout in several (8-10 large watersheds) throughout their nativ

Decision-support for headwater stream habitats

Coldwater stream habitats are at risk from climate change, but management actions, such as removing barriers to passage and restoring riparian forest canopies, can in some cases help to ameliorate negative impacts.  Our overall goal is to devise and implement decision-support tools to help managers make climate-appropriate management choices.  We are currently working on several different approaches to this problem.

Science to examine the interactions between climate, agriculture, and water quality

The purpose of the project was to conduct an extensive search for both published and ongoing research that, in general, deals with climate change and agriculture in a water quality context for the Eastern Tallgrass Prairie and Big Rivers Landscape Conservation Cooperative (LCC) and Upper Midwest and Great Lakes LCC. The search was two-fold; one portion of the search dealt with an on-line literature search for published peer-reviewed articles for the time period of 2000 (sometimes slightly earlier depending on the relative degree of the publication’s relevance to the topic) to present.

A research and decision support framework to evaluate sea-level rise impacts in the northeastern U.S.

Previous approaches to quantify coastal vulnerability to sea-level rise have had major shortcomings, including the possibility that their underlying assumptions are not uniformly valid. This project conducted a study to distinguish the differing ways that coastal areas of the northeastern U.S. will respond to sea-level rise. This information will be used to develop a scientific research and decision-support program that addresses the cross-cutting and unique problems in these areas related to climate change and sea-level rise.

A stream temperature inventory network and decision support metadata mapper - evaluating the resources to understanding climate change effects on streams in New england and the Great Lake's states

Stream data for the northeastern U.S. are needed to enable managers to understand baseline conditions, historic trends, and future projections of the impacts of climate change on stream temperature and flow, and in turn on aquatic species in freshwater ecosystems. This project developed a coordinated, multi-agency regional stream temperature framework and database for New England (ME, VT, NH, CT, RI, MA) and the Great Lakes States (MN, WI, IL, MI, IN, OH, PA, NY) by building a community around the efforts of this study.

Bringing people, data, and models together – addressing impacts of climate change on stream temperature

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 Climate Science Center domain.

Developing fish trophic interaction indicators of climate change for the Great Lakes

This project addressed regional climate change effects on aquatic food webs in the Great Lakes. Project scientists examined Lake Erie as a representative system with a high level of human impact, varying levels of food availability, seasonal hypoxia (low oxygen levels), and spatial overlap of cold- and cool-water fish guilds. In Lake Erie and in large embayments throughout the Great Lakes basin, this situation is a concern for fishery managers, as climate change may worsen oxygen levels and reduce habitat for some species.

Characterization of spatial and temporal variability in fishes in response to climate change

The number of fish collected in routine monitoring surveys often varies from year to year, from lake to lake, and from location to location within a lake.  Although some variability in fish catches is expected across factors such as location and season, we know less about how large-scale disturbances like climate change will influence population variability.  The Laurentian Great Lakes in North America are the largest group of freshwater lakes in the world, and they have experienced major changes due to fluctuations in pollution and nutrient loadings, exploitation of natural resources, intr

Critically evaluating existing methods and supporting a standardization of terrestrial and wetland habitat classification and mapping that includes characterization of climate sensitive systems

This project facilitated coordination among the scientific community to provide a comparison of existing habitat classification and mapping products within the footprint of the Northeast Climate Adaptaion Science Center (NE CASC). This study also provided an evaluation of habitat vulnerability to climate change within the region and recommendations for needed improvement in habitat mapping products for the future.
