Climate change and associated stressors are expected to greatly impact the ability of forest managers to sustainably manage and conserve forest habitats across the northeastern United States. As a result, adaptation strategies are being developed and applied in many regions to minimize climate change impacts and sustain key forest functions under uncertain future environmental conditions. Given that many of these strategies deviate from traditional approaches to forest management, there is a great need for field evaluations of adaptation in practice to inform long-term planning efforts to address climate change impacts. Similarly, the long timeframes over which forests develop and management actions operate has...

Coastal National Wildlife Refuges (NWRs) provide a myriad of beneficial services, including buffering storm surge, improving water quality, supporting commercial fisheries, and providing habitat for imperiled wildlife and plants. Yet in the last century, coastal ecosystems in the eastern U.S. have been severely altered by human development activities as well as sea-level rise and more frequent extreme events related to climate change. These influences threaten the goods and services provided by NWRs and pose decision-making challenges for refuge managers. The purpose of this project was to explore how structured decision-making – a formal, systematic method for analyzing decisions – could help NWR staff make informed...
With this tool, managers can evaluate how streams of interest are currently impacted by land use and assess if those habitats may change with climate.
The intent of this webinar is to introduce a decision support tool that displays results of a stream fish habitat condition assessment for current and future time periods in the NE CSC region. To characterize current condition of stream habitats, we developed three indices based on fish species response to land use, water quality impairment, and stream fragmentation by large dams. Using these indices, streams were scored to reflect their risk of habitat degradation. We also classified streams based on current climate and sensitivity of fish species to a suite of water temperature and flow metrics. These relationships were used to assign stream classes based on future climate conditions. This allowed us to identify...

This dataset represents results from this study attributed to the NHDPlus stream reach segments. Human impacts occurring throughout the Northeast and Midwest United States, including urbanization, agriculture, and dams, have multiple effects on the region’s streams which support economically valuable stream fishes. Changes in climate are expected to lead to additional impacts in stream habitats and fish assemblages in multiple ways, including changing stream water temperatures. To manage streams for current impacts and future changes, managers need region-wide information for decision-making and developing proactive management strategies. Our project met that need by integrating results of a current condition...
Abstract (from https://link.springer.com/article/10.1007/s10980-016-0473-8): Context Global climate change impacts forest growth and methods of modeling those impacts at the landscape scale are needed to forecast future forest species composition change and abundance. Changes in forest landscapes will affect ecosystem processes and services such as succession and disturbance, wildlife habitat, and production of forest products at regional, landscape and global scales. Objectives LINKAGES 2.2 was revised to create LINKAGES 3.0 and used it to evaluate tree species growth potential and total biomass production under alternative climate scenarios. This information is needed to understand species potential under...

Abstract (from https://link.springer.com/article/10.1007/s10980-016-0429-z): Context Forests in the northeastern United States are currently in early- and mid-successional stages recovering from historical land use. Climate change will affect forest distribution and structure and have important implications for biodiversity, carbon dynamics, and human well-being. Objective We addressed how aboveground biomass (AGB) and tree species distribution changed under multiple climate change scenarios (PCM B1, CGCM A2, and GFDL A1FI) in northeastern forests. Methods We used the LANDIS PRO forest landscape model to simulate forest succession and tree harvest under current climate and three climate change scenarios from...

Abstract (from http://forestry.oxfordjournals.org/content/87/5/629.abstract): The contribution of understorey vegetation (UVEG) to forest ecosystem biomass and carbon (C) across diverse forest types has, to date, eluded quantification at regional and national scales. Efforts to quantify UVEG C have been limited to field-intensive studies or broad-scale modelling approaches lacking field measurements. Although large-scale inventories of UVEG C are not common, species- and community-level inventories of vegetation structure are available and may prove useful in quantifying UVEG C stocks. This analysis developed a general framework for estimating UVEG C stocks by employing per cent cover estimates of UVEG from a region-wide...
Abstract (from http://www.sciencedirect.com/science/article/pii/S0006320715001834): Continental-scale monitoring programs with standardized survey protocols play an important role in conservation science by identifying species in decline and prioritizing conservation action. However, rare, inaccessible, or spatially fragmented communities may be underrepresented in continental-scale surveys. Data on these communities often come from decentralized, local monitoring efforts that differ in their goals and survey protocols. We combine 16 point count datasets, controlling for differences in protocol and detection probabilities to estimate regional trends for 14 spruce-fir forest bird species across Northeastern and Midwestern...
Abstract (from ScienceDirect): Maximum stand density index (SDImax) is an important factor controlling stand dynamics that varies by species and region, but less is understood how it differs within a region for a given species. In this analysis, linear quantile mixed modeling (LQMM) and an extensive network of permanent plots were utilized to examine regional variation in the SDImax of 15 species (7 softwoods and 8 hardwoods) across the complex forests of the Acadian Region in North America. Observed plot-level SDImax was then linked to various stand, plant trait, site, and climatic factors and the spatial patterns throughout the region examined. Results indicated high variability of SDImax for a given species with...
Abstract: Grassland birds are declining faster than any other bird guild across North America. Shrinking ranges and population declines are attributed to widespread habitat loss and increasingly fragmented landscapes of agriculture and other land uses that are misaligned with grassland bird conservation. Concurrent with habitat loss and degradation, temperate grasslands have been disproportionally affected by climate change relative to most other terrestrial biomes. Distributions of grassland birds often correlate with gradients in climate, but few researchers have explored the consequences of weather on the demography of grassland birds inhabiting a range of grassland fragments. To do so, we modeled the effects...

Forests in the Eastern United States are in the early- and mid-successional stages recovering from historical land use. Succession, harvest, and climate are potentially important factors affecting forest composition and structure in the region. The goal of this project was to predict the distribution and abundance of dominant tree species across portions of the Eastern U.S. under alternative climate scenarios from present to the end of the century. We used the forest landscape change LANDIS PRO and hybrid empirical-physiological ecosystem model LINKAGES to model changes in forest biomass and species abundances and distribution in the North Atlantic region of the U.S. while accounting for climate change, succession,...
Abstract (from http://www.sciencedirect.com/science/article/pii/S0378112714003028): Plant functional traits (PFTs) have increased in popularity in recent years to describe various ecosystems and biological phenomena while advancing general ecological principles. To date, few have investigated distributional attributes of individual PFTs and their relationship with key attributes and processes of forest ecosystems. The objective of this study was to quantify the distribution and contribution of various PFTs in determining forest structure, live tree production (volume and biomass), and tree mortality across the eastern US. In total, 16 metrics representing species specific gravity and their shade, flood, and drought...
Abstract (from https://link.springer.com/article/10.1007/s10980-017-0487-x): Context Temperate grasslands and their dependent species are exposed to high variability in weather and climate due to the lack of natural buffers such as forests. Grassland birds are particularly vulnerable to this variability, yet have failed to shift poleward in response to recent climate change like other bird species in North America. However, there have been few studies examining the effect of weather on grassland bird demography and consequent influence of climate change on population persistence and distributional shifts. Objectives The goal of this study was to estimate the vulnerability of Henslow’s Sparrow (Ammodramus henslowii),...
College of Menominee Nation Sustainable Development Institute hosted a 3-day summit in October 2014 focused on different levels of climate change adaptation training for Tribes. This event included opportunities to network between indigenous practitioners, tribal leaders and land managers, federal agencies, and climate change scientists. The information was specific to the Northeast region, but was open to all who were interested in the issues of climate change and Tribes. The Summit provided an opportunity to gain introductory and more advanced climate change adaptation planning skills and information, identify next steps for adaptation, and make connections between tribes and academic/governmental climate change...

Abstract (from British Ecological Society): Tree harvest and climate change can interact to have synergistic effects on tree species distribution changes. However, few studies have investigated the interactive effects of tree harvest and climate change on tree species distributions. We assessed the interactive effects of tree harvest and climate change on the distribution of 29 dominant tree species at 270 m resolution in the southern United States, while accounting for species demography, competition, urban growth and natural fire. We simulated tree species distribution changes to year 2100 using a coupled forest dynamic model (LANDIS PRO), ecosystem process model (LINKAGES) and urban growth model (SLEUTH). The...
