Management for old-growth characteristics and late-successional biodiversity in temperate montane forests Presenter: William Keeton, University of Vermont Rubenstein School of Environment and Natural Resources Many have wondered if active management could be used to restore some characteristics of High Conservation Values forests, such as increasingly rare temperate old-growth systems, to managed landscapes. Silvicultural systems for this purpose are being tested in several regions globally and have been the focus of the Vermont Forest Ecosystem Management Demonstration Project (FEMDP), now in its 15th year. The FEMD is testing the hypothesis that an approach called "Structural Complexity Enhancement" (SCE) can accelerate rates of late-successional/old-growth development faster than conventional selection systems. The study employs a Before-After-Control-Impact experimental design to compare SCE against modified single-tree and group selection treatments. Manipulations and controls were applied to 2 ha experimental units and replicated four times at two research areas in Vermont. Field data were collected over two years pre- and 13 years post-treatment. Operational expenses and revenue were tracked as was information on market conditions.
Ten years after harvest, measured aboveground carbon in SCE units was 15.9% less than simulated no-harvest baselines, compared to 44.9% less in conventional treatments. Statistical results show that herbaceous understory composition was strongly affected by overstory treatment and less influenced by soil chemistry and drought stress. However, diversity for sensitive, late-successional herbaceous plants increased significantly in SCE units and decreased significantly in the semi-open conditions within group selection units. Fungi and salamander responses were strongly associated with microsite characteristics, particularly coarse woody debris, and increased significantly under SCE, but showed no statistically significant decrease in gaps created by group selection. SCE is economically viable under the right site and market conditions, but does not maximize timber revenue. Potential applications include old-growth restoration, riparian restoration, carbon management, and low intensity commercial management. Silviculture promoting old-growth characteristics can contribute to biodiversity conservation and terrestrial carbon storage in northern hardwood-conifer systems while providing both timber and non-timber economic opportunities.

Mountain hydrology – 15 years of streamgaging on Mount Mansfield Jamie Shanley (US Geological Survey), Beverley Wemple (University of Vermont) Presenter: Jamie Shanley, US Geological Survey Since 2000, VMC has supported stream gaging for a paired watershed study by USGS, UVM and others at Mt. Mansfield. The paired watershed approach was designed to assess the effects of high-elevation development, but has also generated compelling findings on the nature of extreme hydrologic events in Vermont's mountains. Our results suggest that extreme events in the mountains are more frequent, more extreme, and more localized than the events that make headlines in the populated lowlands. | |||||
Decline of bumblebee species diversity in Vermont, 1900-2013 Leif L. Richardson, Kent McFarland and Sara Zahendra Presenter: Leif L. Richardson, Gund Institute for Ecological Economics, University of Vermont Bumblebees (Bombus; Apidae) are important components of temperate ecosystems, playing key roles in the pollination of wild and crop plants. Bees face many threats, yet efforts to assess conservation needs are hampered by a lack of data on historical distributions of most species. To address this deficit, we conducted a survey of the bumblebee species native to Vermont. We identified and digitized 1,669 historical specimens held by museums, and made new collections, including a citizen science effort in 2012-2013 that netted >10,000 new records. Comparing these historic and modern datasets, we conclude that 29% of the 18 species historically present have been extirpated since 2000, and an additional 22% are threatened. We find strong geographic patterning to the data, with factors such as road density and land use patterns predicting distribution of some species. Based on our assessment, three bumblebee species, Bombus affinis, B. ashtoni and B. terricola, have been afforded protection by the state’s endangered species statute. Given rapid changes in bee species distribution, this inventory forms a critical baseline to which future surveys of these important insects can be compared. | |||||

Effectively Communicating Science: Lessons Learned Presenter: Sandy Wilmot, Vermont Department of Forests, Parks and Recreation You may be a brilliant scientist achieving wonders in your area of expertise, but how effectively are you reaching non-scientists? If there is to be real progress in land use and resource management, graphs and charts with plenty of statistics may not bear fruit. Reasons are plenty for ineffective communication with non-science audiences. New studies are helping explain why our science message may be falling flat. This presentation will share lessons learned in communicating ecosystem science by VMC Cooperators, by staff at the Agency of Natural Resources, and by other Vermont science organizations, in the context of new social studies. In an era where science is not held as truth on a pedestal, there is need for more scientists who become expert science communicators. | |||||
Edge of Field Monitoring in Vermont Fletcher (Kip) Potter, USDA/NRCS Julie Moore, Stone Environmental Dave Braun,Stone Environmental Don Meals,Stone Environmental Mike Middleman,VAAFM Eric Howe,LCBP Presenter: Fletcher (Kip) Potter, USDA/NRCS Nonpoint runoff from agricultural lands is a major source of phosphorus loading to Lake Champlain. In some Vermont watersheds agriculture is estimated to contribute as much as 62% of the total phosphorus load. For decades NRCS and VAAFM have been recommending and providing technical and financial support for conservation practices to reduce sediment and phosphorus loss from Vermont farms. For some of these practices there is very little relevant data on their effectiveness. In 2012 NRCS in Vermont initiated an effort to evaluate selected agricultural practices using an “edge of field” monitoring system. These systems are using a paired watershed, or an above and below experimental design, with a monitoring period of 3 to 5 years. Treatment results will be available from the first projects sometime in early 2016. Monitoring data collected from these projects during the calibration period has provided important information on phosphorus concentrations and loadings in surface runoff from agricultural fields. As part of NRCS’s new National Edge of Field Monitoring Program new monitoring projects will quantify phosphorus loadings in tile drainage water and determine the effectiveness. | |||||
Not your parents’ field guide: a site-specific macroinvertebrate IPhone app for citizen scientists. Declan McCabe; Janel Roberge; Lindsay Wieland; Patrick Clemins; Steven Exler; Erin Hayes-Pontius; Lillian Gamache; Elissa Benedetto; Jeremy Gould; My Mai; Lara Nargozian; Colum Smith Presenter: Declan J. McCabe, Saint Michael's College Biology Taxonomic keys are the gold standard for aquatic invertebrate identification. Keys work by elimination; we find the needle in the haystack by removing hay until just the needle remains. Frustrated students wading through keys, often 'learn' that the organism sampled in Vermont occurs only in California. Field guides reduce the list of organisms to a common, broadly-distributed subset of a taxon. Keys and guides are of limited use when citizen scientists attempt to accurately identify organisms from particular sites. To lower barriers for high-school collaborators, faculty and students working on Vermont EPSCoR projects (NSF Grant EPS-1101317) developed tailored field guides to macroinvertebrates for specific streams. The guides are hosted on a wiki site mirrored on an IPhone app. To build each wiki page, we sampled 86 streams in Vermont, New York, and Puerto Rico to develop lists of commonly collected organisms. For each organism, we developed a web template that includes a photograph, description, and ID tips. The templates are used on multiple pages on the web or hand-held device. Organisms newly found can easily be added to existing field guides. The hand-held app can be synchronized with the web page using wifi or cell connections and then used at field sites lacking web connections. The free app is available in Apple's App Store. | |||||

Tracking parcelization and addressing forest fragmentation – tools and strategies for reversing negative trends in Vermont. Presenter: Jamey Fidel, Vermont Natural Resources Council Despite being so heavily forested, for the first time in over a century Vermont is losing forestland due to parcelization, suddivision, land clearing and development. In order to minimize the effects of parcelization and subdivision, it is necessary to understand where it is occurring, the rate at which it is occurring, and how it can be managed to reduce its impacts. This presentation will share data on recent trends, and examine strategies that are being developed for land managers, conservation organizations, municipalities, and the Vermont Legislature to address parcelization and forest fragmentation. The presentation will also explain a new tool that is being developed to create a user friendly webpage and interactive map interface that will allow for the visual inspection, querying and dissemination of parcelization and subdivision data on an annual basis over time. This tool will benefit researchers, state agencies, municipalities, professional planners, land managers, foresters, conservation organizations, and interested citizens in their ability to develop effective strategies to keep forestland intact in Vermont. | |||||
High-resolution Mapping of Potential Vernal Pools using LiDAR and Object-based Image Analysis Sean MacFaden, University of Vermont Spatial Analysis Laboratory Steven Faccio, Vermont Center for Ecostudies Presenter: Sean MacFaden, University of Vermont Spatial Analysis Laboratory Given the ecological significance of vernal pools as essential breeding habitat for amphibians, there is much interest in finding efficient techniques for mapping potential pools across large study areas. Automated identification of potential vernal pools is now possible with a combination of LiDAR and object-based image analysis (OBIA), an expert-system approach that incorporates landscape context and other traditional elements of image interpretation. An OBIA model for Addison County, Vermont used LiDAR-derived topographic models to identify candidate landscape depressions and then used LiDAR intensity and 4-band multispectral imagery (visible bands plus near infrared) to classify them according to the likely presence of water during spring conditions. When compared to an existing database of potential vernal pools in Vermont, the model captured 91% of the pools with discernible evidence of water. As LiDAR availability increases in Vermont and elsewhere in the Northeast, this mapping approach can help facilitate vernal pool conservation by expediting initial identification of potential pools and guiding field-based examination of functional amphibian breeding habitat. | |||||
Improving Large-scale Forest Mapping in the Northeast: Coupling Pixel-based and Object-based Classification of Multitemporal Landsat Imagery David Gudex-Cross, Jennifer Pontius, and Alison Adams Presenter: David Gudex-Cross, Rubenstein School of Environment and Natural Resources, UVM Spatially-explicit distribution maps of tree species are increasingly valuable to forest managers and researchers, particularly in light of the anticipated effects of climate change and invasive pests on forest resources. Yet, current regional and national forest cover maps provide only coarse classifications (e.g. deciduous, evergreen, or mixed) with minimal validation. Advanced remote sensing techniques, such as spectral unmixing and object-based image analysis (OBIA), offer a novel approach to mapping species distributions by utilizing multitemporal imagery and a suite of ancillary datasets to quantify basal area on a per-species basis. Spectral unmixing outperforms traditional pixel-based classifiers by decomposing (“unmixing”) mixed pixels and assigning tree species proportions for each pixel. This is particularly useful in northern forests where species composition is often mixed. Here, we present an integrated pixel-based unmixing and OBIA method for quantifying basal area distribution for 12 key tree species using multitemporal Landsat TM imagery. We highlight the accuracy of this approach, as well as how it compares to traditional forest distribution maps. | |||||
| 2:00 to 2:20 | An Overview of the Vermont Boreal Flora Robert Popp + ABSTRACT | Climate-driven changes in energy and mass inputs alter N:P stoichiometry differently in deep and shallow sites in Lake Champlain Peter D.F. Isles + ABSTRACT | Drones Mapping Vermont's Changing Landscape Jarlath O'Neil-Dunne + ABSTRACT | ||
An Overview of the Vermont Boreal Flora Robert Popp Presenter: Robert Popp, Vermont Fish & Wildlife Dept. While it is speculated that the boreal flora of the Northeast is under increasing threat due to climate shifts, the evidence from Vermont shows a mix of increases and declines. We look at several species at a number of sites in Vermont and speculate as to the possible cause of any population shift. On Mt. Mansfield anecdotal observations indicate a possible decline in Diapensia lapponica; however a new population was recently discovered at a new location in 2014. Dryopteris fragrans, another boreal species was relocated in 2014 at a site where it had not been observed since 1906. Lastly, a site for a number of populations of boreal calcareous species that was visited by Pease in 1929 was relocated and all but one of the rare boreal species were still extant. All of these locations have the benefit of either being remote or closed to the public whereas noticeable declines in the boreal flora have been documented at smaller, more heavily visited sites such as Mt. Abraham and Mt. Hunger. We speculate that much of the decline in boreal species may be due to trampling by hikers rather than to climate change and monitoring protocols must be adjusted accordingly. | |||||
Climate-driven changes in energy and mass inputs alter N:P stoichiometry differently in deep and shallow sites in Lake Champlain Peter D.F. Isles, Yaoyang Xu, Jason D. Stockwell, Andrew W. Schroth Presenter: Peter D.F. Isles, Rubenstein School of Environment and Natural Resources, UVM The balance of nitrogen (N) and phosphorus (P) is a key factor controlling the likelihood of cyanobacteria blooms in lakes. Concentrations of N and P i may be affected differently by nutrient delivery from watersheds and by changes in rates of internal nutrient cycling driven by physical conditions such as temperature and stratification, and both nutrients and energy inputs are likely to change with climate warming. Responses of lake nutrients to changing climate may be different in deep and shallow basins, due to the accessibility of sediments in shallow sites. In this study, we use 23 years of monitoring data to compare long-term trends in total N (TN), total P (TP) and TN:TP at 15 sites in Lake Champlain to external nutrient inputs as well as long-term meterological trends. We find that TN:TP has declined sharply lake-wide, particularly in the past decade. In deep sites, these declines appear to have been driven by the ratio of dissolved N:P in tributary inputs and by decreases in hypolimnetic dissolved oxygen. In shallow sites, declines in N:P appear to be primarily driven by long-term increases in temperature and decreases in wind speeds. | |||||

The role of climate in sugar maple health: projections for the future Jennifer Pontius, Evan Oswold, Sandy Wilmot, Shelly Rayback and Lesley-Ann Dupigney-Giroux Presenter: Jennifer Pontius, UVM RSENR and USFS NRS We compare sugar maple health metrics from long-term monitoring plots to downscaled climate data, including several novel ecological-climate indicators to better understand how climate patterns influence sugar maple condition and the implications for the future of sugar maple in Vermont.
Results indicate that there are several specific climate metrics that have historically influenced sugar maple health at levels comparable to the variability introduced by defoliation and other disturbance events. The nature of these variables indicate that it is important for any assessment of sugar maple response to climate change include more nuanced and spatially explicit climate metrics, as opposed to gross estimates of average or extreme temperatures.
Our projections of how these key climate variables may change over the next 75 years indicate that this trend towards increased climate-induced decline will only increase in severity and extent. We suggest that land managers take steps to protect sugar maple stands currently located in more favorable climate islands identified here in order to maximize the sustainability of this critical resource.

Assessment of Vermont Department of Environmental Conservation Watershed Management Division’s LaRosa Partnership Program Caitlin Trimmer, Samantha Clerkin, Lauren Jenness Presenter: Rachael DeWitt, University of Vermont Rubenstein School of Environment and Natural Resources The Vermont Department of Environmental Conservation (VTDEC) Watershed Management Division monitors water quality throughout Vermont. Its goal is to protect, maintain, enhance, and restore the state’s surface waters. Their goals are achieved with the help of watershed management associations, monitoring groups, and citizen scientists located throughout Vermont. Each organization monitors water quality and implement projects within their watershed. The Watershed Management Division developed the LaRosa Partnership to assist watershed associations with the laboratory analysis of their water samples. The VTDEC is currently seeking feedback on how to improve and evolve the LaRosa program. Our team is conducting interviews with representatives from the watershed associations involved in the program in order to obtain an informed perspective of the current status of the program’s effectiveness. This presentation will feature our recommendations for the LaRosa program moving forward.

Calculating carbon storage in the Northern Forest: a methods comparison Alison Adams, Jennifer Pontius, Gillian Galford, David Gudex-Cross Presenter: Alison Adams, UVM Rubenstein School of Environment & Natural Resources Accurate measurement of carbon storage (CS) in forests is crucial to determine the impact of changes in forest cover on carbon cycles. CS estimates interpolated from forest inventory data are widely-used, but are resource-intensive and inaccurate in heterogeneous landscapes. Remotely-sensed data products, combined with novel software (Dinamica-EGO), provide an opportunity to improve carbon assessments in such landscapes. This study compares the impact of using remote sensing inputs with different degrees of forest type specificity when assessing carbon in Vermont forests. Specifically, we compared: 1) calculations based on species basal area maps matched with species-specific allometric equations, 2) calculations based on common forest species assemblages (e.g. spruce/fir, maple/beech/birch), and 3) calculations based on coarse land cover type classifications (e.g. deciduous, evergreen, mixed). Validation using VMC forest inventory plots allowed us to determine the most accurate landscape scale CS model, and to analyze how that differs from traditional approaches. This information is critical to understanding the role of the Northern Forest in carbon storage and sequestration. | |||||

Class I Wetlands - Planning Public Outreach and Organizing for the Greatest Wetland Protection
Invitation-only
Class I Wetland designation provides the strongest protection for VT's wetlands. A Class I designation requires compelling public support, so how do we plan for successful designations for VT's most valuable wetlands? The session will start with a background on Class I wetland designations and an overview of the new process the State of VT has been developing to identify these wetlands, and then move on to the question of how we can get the public involved with the process in a positive way. In this working session we will discuss: where's the best place to start, what's the best way to organize this process, how do we get the word out, and how do we find our strongest partners.

Exploring a Forest Indicators Dashboard
Open to All
We explore the utility of using a coarse assessment of multiple forest health metrics to summarize the relative condition of Vermont's forests compared to historical records. This will include a discussion of additional data sets for inclusion, potential uses of such a tool, potential drawbacks of summarizing a complex system in a simple metric, and outlets for dissemination.

Forest-Lake Connections
Open to All
A great deal of limnological research in Vermont has focused on agricultural impacts on Lake Champlain, however many of Vermont's smaller lakes exist in predominantly forested catchments, which may be experiencing different stressors as a result of changes in climate, atmospheric nutrient and acid deposition, and forest ecosystem changes. For example, many lakes in forested catchments in Sweden and Canada have experienced "browning" as a result of increasing DOC concentrations, reducing lake productivity and altering the balance between carbon sequestration and carbon release. Lakes may also act as "climate sentinels," providing integrated information about climate effects on watershed processes. In this session, we will bring together researchers in forestry, hydrology, and limnology to address the availability of complimentary datasets in Vermont lakes and forests and identify sites where increased data may lead to valuable insights about forest and small lake ecosystems.

Incorporating Forest Management And Stakeholder Expertise Into A Vermont-Specific Forest Management Decision Support Tool
Invitation-only
The Forest Health and Climate Research Group in the Rubenstein School at the University of Vermont is developing a tool to inform forest management in Vermont under conditions of global change. This tool is intended to be used by forest managers and stakeholders. It will be different from coarser, regional scale tools such as Tree Atlas because it will be Vermont-specific and incorporate forest management activities. The purpose of the working session is to gather input from potential users of the tool.

Monitoring Earthworm Invasions into Northern Hardwood Forests
Open to All
Earthworm invasions represent a serious threat to forest health. However, resources are scarce to detect affected ecosystems and judge the degree of damage done. Volunteer networks of citizen scientists are probably the only practicable way to assess and monitor the state of the invasion in northeastern forests. In this workshop you will learn the telltale signs of earthworm invasions and how you can contribute to public awareness of this invasion and inform the forest and ecological science community by utilizing social media.

Overcoming the Barriers to PPSR
Open to All
PPSR is the acronym for Public Participation in Scientific Research, otherwise known as citizen science. As citizen science has grown in popularity, some professional scientists are skeptical of the public's scientific potential. Additionally, the excitement behind the crowdsourcing trend has led to projects without support from professional scientists and with data being collected without a defined and relevant purpose. In this working group, we'll look at some exemplary projects, hear about their stumbling blocks and tips for success, as well as, identify potential future projects where PPSR could be used effectively.

Descriptions of Morning Plenary Lightning Talks
(In order of appearance)
Tree Pests & Damage, Barbara Schultz - Monitoring for tree pests and other damage causing agents began in the early days of the Vermont Forest Service. Recent surveys and older archives both help identify and evaluate threats to forest tree health.
Tree Growth Trends, Paul Schaberg - Tree increment cores provide a datable record of tree woody growth for long periods of time (e.g., decades to centuries). My research group is building a tree ring database to compare the current and past growth of major species in Vermont to assess 1) differences in growth among species, 2) if growth is changing over time, and 3) what environmental parameters (e.g., temperature, precipitation, pollutant inputs, etc.) are best related to growth patterns.
Phenology, Josh Halman - The coordinated work of VMC and the Vermont Department of Forests, Parks and Recreation has allowed us to capture 25 years of data on the timing of budbreak and foliar senescence of sugar maple (Acer saccharum Marsh.) in Underhill, VT. These data show trends towards an earlier onset of spring, and a later onset of autumn, thereby resulting in a longer growing season. We intend to continue monitoring these phenological events to further identify the impacts of a changing climate on Vermont forests.
Forest Fragmentation, Michael Snyder - The 2015 Vermont Forest Fragmentation Report was presented to the legislature this past April. This talk will provide an overview of the report, what it includes, what it has led to, and where we expect to go from here, with a call for action and input from VMC.
Climate, Lesley-Ann Dupigny-Giroux - This talk will use a systems view to explore the multiple, interacting ways in which both the atmosphere and land processes influence the health and functioning of forests across Vermont. A long-term perspective will be taken and a segue to future impacts will be presented.
Acid Deposition, Rich Poirot - Concern over the effects of acidic sulfate and nitrate air pollution concentrations and deposition on Vermont’s air quality, surface waters and forested ecosystems was one of the principal motivations for the formation of the VMC 25 years ago. Since that time, VMC cooperators have measured the concentrations and deposition of acidifying pollutants at or near the Mt. Mansfield and Lye Brook VMC sites. The long-term trends document that substantial progress has resulted from controls of pollution emissions in upwind regions, but the most recent data show that continued reductions are needed in the future.
Monitoring Water Quality, Jim Kellogg - Monitoring water quality has changed considerably over the years with more emphasis on bioassessments in streams. This rigorous tool allows for a determination to be made of a stream’s health. Chemical trends are still used widely in DEC lake investigations such as the Long-term Monitoring (LTM) of Acid Lakes.
Mercury, Jamie Shanley - Like acid rain, mercury enters ecosystems from atmospheric deposition, both wet and dry. Mercury deposition has been monitored at Proctor Maple Research Center since the late 1990s, and VMC researchers have studied ecosystem effects of mercury. This synopsis will frame the mercury issue, what we know about mercury in Vermont ecosystems, and the outlook for the future.
Soils, Scott Bailey - The soils of Vermont have been evolving since the Ice Age ended about 12,000 years ago. Over the last 25 years there has been an increased interest in short term (decadal) changes in soils caused by air pollution, land use legacies, and a changing climate. The VMC has been a leader in promoting soils as an environmental monitoring medium, much as air and water quality are used as indicators of environmental conditions and change.
Vermont's Big Game Mammals, Mark Scott - A snapshot on Vermont’s large mammals: moose, bear, and white-tailed deer – historical, present and future projections. What impacts has Vermont’s environment had on these critters or what impacts have they had on Vermont’s forests. Will these mammals be widespread in 2050? Presentation will share annual data collected the past three decades on these species by Vermont Fish & Wildlife scientists.
Bat Populations, Alyssa Bennett - White-nose Syndrome, a deadly fungal disease, has caused massive population declines in several hibernating bat species. Bat population trends in Vermont will be discussed in light of current and evolving survey methods and implications to the greater forested ecosystem.
Amphibian and Reptiles, Jim Andrews - Our state-wide atlas efforts are setting an important baseline for future comparisons but were not designed to show changes on an annual scale. However, monitoring at Mt. Mansfield was designed to be able to show any annual changes in local populations. Different species have responded differently to changes in the local forested ecosystem with some showing long-term declines (e.g., Spring Peeper), some showing long-term increases (Eastern Red-backed Salamander), and others remaining quite stable (Spotted Salamander). The different life histories of those species suggest potential reasons for those differences.
Forest Birds, Steve Faccio - Since 1989, skilled volunteer birders with the Vermont Forest Bird Monitoring Program have conducted annual breeding bird surveys at ~30 interior forest study sites across the state. This talk will present results from a 25-year analysis of these data, highlighting long-term population trends of forest songbirds.
