Dead and downed wood in any forest serves an important ecological function with regards to decomposition and nutrient cycling in forest ecosystems. It also provides critical habitat for many reptile and amphibian species, such as the red-backed salamander (Plethodon cinereus), in addition to providing an important food source for insects and detritivores upon which many other species in the system depend. The GCPO LCC Integrated Science Agenda (ISA) targets density of down wood around one 6’ dead/down log of ≥8” dbh per acre, essentially saying that on every acre there needs to be at least one sizable down log. The U.S. Forest Service (USFS) Forest Inventory and Analysis program does not collect plot-level data...

These layers represent estimates of imputed tree density calculated as part of the ecological assessment of upland hardwood systems. The GCPO Integrated Science Agenda targets tree densities of around 40 trees/acre for upland hardwood woodland systems and around 80 trees/acre for upland hardwood forest systems. These metrics should be correlates with target endpoints of basal area and canopy cover, though not entirely synonymous. We again used plot-level FIA data imputed across the GCPO LCC to assess tree density. However, it was challenging to identify and map the very limited acreage amounts meeting exactly this target in upland hardwood woodlands and forest. We therefore assessed the mean tree density within...

This web map provides a watershed index of surface drinking water importance, a watershed index of forest importance to surface drinking water, and a watershed index to highlight the extent to which development, fire, and insects and disease threaten forests important for surface drinking water. This tabular dataset is meant to be joined with the NRCS Watershed Boundary Dataset HUC-12. The results of this assessment provides information that can identify areas of interest for protecting surface drinking water quality. The spatial dataset can be incorporated into broad-scale planning, such as the State Forest Action Plans, and can be incorporated into existing decision support tools that currently lack spatial...

Sea-level rise will eventually flood and kill many coastal mangrove trees. The loss of mangrove forests will strongly affect human populations on isolated western Pacific islands as they rely heavily on mangroves for food, such as fish, shrimp, and crabs; building materials; and fire wood. Mangroves also shelter coastal communities from the impacts of tsunamis and cyclones, are home to endangered species such as the Yapese monarch and flying fox, and remove and store CO2 from the atmosphere. In the past, mangroves have adjusted to sea-level rise through tree root growth and the accumulation of sediments from rivers and oceans, processes which allow them to maintain their forest floor elevation relative to sea level....

The Forests to Faucets project uses a GIS to model and map the land areas across the United States that are most important to surface drinking water sources, as well as to identify forested areas important to the protection of drinking water and areas where drinking water supplies might be threatened by development, insects and diseases, and wildland fire. The results of this assessment provide information that can identify areas of interest for protecting surface drinking water quality. The spatial dataset can be ncorporated into broad-scale planning and can help identify areas for further local analysis. In addition it can be incorporated into existing decision support tools that currently lack spatial data on...

Under shifting temperatures and precipitation patterns, Midwestern states are increasingly at risk from non-native invasive plants that are changing the composition, structure, and function of native forests. Non-native invasive plants impact the resilience and sustainability of forest communities by outcompeting native tree seedlings and diverse flowering plants, and by altering ecologically important patterns of natural processes like fire, wind, drought, and flooding. Land managers facing this threat are having to not only consider current non-native invasive plants within their landscapes but also future impacts with the expansion of these plants northward and westward under a changing climate, especially as...

Tribal nations in the Pacific Northwest have distinctive, long-standing relationships with their aboriginal lands and associated resources. These relationships are being disrupted by changing climate conditions. Most scientific information about changes in forests and other ecosystems have not been directed toward addressing the concerns of tribal communities. For example, they lack culturally-specific information pertaining to tribal knowledge systems, cultural practices, livelihoods, food and water security, and economies. Furthermore, ensuring that research is conducted in ways that are relevant to tribes is difficult when those who produce these studies lack experience in working with tribes, and are unfamiliar...

Black ash wetlands occupy over 1.2 million hectares of forest in the Great Lakes region, providing habitat for unique and diverse wildlife communities. In these wetlands, black ash trees are a foundational species, regulating all aspects of ecosystem function, and are also an important cultural resource for Native Americans, specifically for basket-makers. Black ash wetlands are critically threatened by the interaction of climate change and the invasive emerald ash borer (EAB), which is expected to spread northward and westward into large expanses of black ash with warming winters. These threats present a significant challenge for long-term conservation efforts to preserve ecosystem functions, cultural lifeways,...

The U.S. Northern Rocky Mountains support a large number of native wildlife species, and survival of these populations depends on connected landscapes to support current migration and dispersal, as well as future shifts in species’ ranges. However, habitat fragmentation and loss threaten these connections. Land and wildlife managers across the U.S. are faced with decisions focused on reducing risks, like those from habitat fragmentation, to wildlife, ecosystems, and landscapes. Establishing connections between natural landscapes is a frequently recommended strategy for these managers to help wildlife adapt to changing conditions. Working in partnership with state and federal resource managers and private land...

In 2017, California was experiencing its most severe drought in over a millennia. Low rainfall and record high temperatures resulted in increased tree mortality and complete forest diebacks across the West. Though land managers scrambled to respond, they lacked information needed to make informed decisions. Focusing on California’s central and southern Sierra Nevada Mountains, this project seeks to determine whether a key forest management practice – forest thinning via prescribed fire – can help forests better survive drought. Prescribed fire is commonly used in the western U.S. to remove potential wildfire fuel, such as small trees and shrubs. It is also thought that this act of selectively removing trees helps...

Fire in the western U.S. poses one of the greatest threats to human and ecological communities alike. In fact, fire management is the largest single expenditure of land management funds on federal lands. Now, climate change is altering wildfire patterns. Climate change in the West is creating warmer and drier conditions, resulting in an increase in the amount of dead vegetation available to fuel fires. This project sought to assess the vulnerability of forests in the southwestern U.S. to climate change and wildfire, in order to understand how these ecosystems might become altered as a result. Researchers (a) examined how climate change impacts wildfires in the region, to better understand fire risk; (b) identified...

The Colorado and Rio Grande Rivers provide drinking water to millions of people in the Southwest and South Central U.S. Snowmelt accounts for 70% of streamflow in these rivers, meaning that water use downstream is directly impacted by snow accumulation and snowmelt patterns in the mountains. Mountain forests are a critical part of the hydrologic cycle that feeds these rivers, providing water supply and storage. However wildfire, which is becoming more common as temperatures rise, can disrupt the role of mountain forests in the hydrologic cycle. Uncertainty about the interactions between wildfire and snow-water, and how these interactions may change as climate conditions shift, impedes effective water resource planning...

Severe droughts cause widespread tree mortality and decreased growth in forests across the globe—even in areas with cooler climates. Mitigating the negative effects of climate change, in particular increased drought frequency and severity, poses a major challenge to forest managers. Managers are searching for strategies that minimize the negative effects of drought on forests (i.e. increase their resistance to drought) and maximize the ability of forests to recover after a drought (i.e. improve their resilience). Evidence suggests that forests with certain combinations of tree species, sizes, and stem densities are better able to withstand and recover from drought. The goal of this study was to identify which...

Overview This project examines the ecological impacts of several introduced and expanding forest insects and diseases on forest habitats across the northeastern US and upper Lake States region. To address these novel threats, this work applies large-scale, co-developed experimental studies documenting impacts of ash mortality from emerald ash borer on lowland black ash communities in the Lake States and northern hardwood forests in New England; regional assessments of the impacts of the climate change-mediated expansion of southern pine beetle into northeastern pine barren communities; and ecological characterizations of areas experiencing suppression efforts to reduce the spread of the introduced Asian long-horned...

The Southeastern United States has vast underground ecosystems where temperatures vary little throughout the year and humidity is always near 100%. These cave and karst ecosystems provide many services to people, such as recreational opportunities, revenue from tourism, and groundwater storage. Caves also provide habitats for important and endangered species, like bats that eat mosquitoes and crop pests. Cave-dwelling species have evolved to live in relatively stable climates, so they may be especially sensitive to climate change. However, it is unclear how surface climate change will affect cave climates and the species that rely on them, because caves are remote environments that have long been difficult to...

The Southeast is currently undergoing high rates of population growth, urbanization, and land use change while also experiencing climatic changes. These changes are and will continue to threaten wildlife and their habitats. Most existing conservation programs and activities, however, focus on maintaining systems in their current condition, or returning them to a historic state, rather than enabling systems to adapt to projected changes. Recognizing this problem state fish and wildlife agencies, together with US Fish and Wildlife Service and others, have initiated the Southeast Conservation Adaptation Strategy (SECAS). This project will support the SECAS effort, which aims to develop a collaborative network of conservation...

This data represents an assessment of forest patch size used in the ecological assessment of upland hardwood systems by the GCPO LCC. We used a combination of remote sensing products including 2011 National Land Cover Database (NLCD) forest classes and the 2011 MAV forest classification layer produced by the Lower Mississippi Valley Joint Venture to delineate patches of all forest types in the GCPO LCC. We used NLCD as the primary data source when assessing forests outside the GCPO LCC MAV subgeography, and the LMVJV forest classification as the primary data source for forest assessment within the MAV. NLCD was developed using 2011 Landsat TM imagery, with forest classes including only areas with trees exceeding...

OSU_SnowCourse Summary: Manual snow course observations were collected over WY 2012-2014 from four paired forest-open sites chosen to span a broad elevation range. Study sites were located in the upper McKenzie (McK) River watershed, approximately 100 km east of Corvallis, Oregon, on the western slope of the Cascade Range and in the Middle Fork Willamette (MFW) watershed, located to the south of the McKenzie. The sites were designated based on elevation, with a range of 1110-1480 m. Distributed snow depth and snow water equivalent (SWE) observations were collected via monthly manual snow courses from 1 November through 1 April and bi-weekly thereafter. Snow courses spanned 500 m of forested terrain and 500 m...
