Fire, Fuels, And Streams: The Effects And Effectiveness Of Riparian Treatments, Josh Mcdaniel

Joint Fire Science Program Digests

Fire is an important disturbance in riparian systems—consuming vegetation; increasing light; creating snags and debris flows; altering habitat structure; and affecting stream conditions, erosion, and hydrology. For many years, land managers have worked to keep fire out of riparian systems through the use of buffers. A number of projects funded by the Joint Fire Science Program are shedding light on the dynamics of fire in riparian systems. Recent research and field practice have shown that (1) riparian treatments can be beneficial and are not as risky as previously thought; and (2) riparian treatments need the “Goldilocks” prescribed fire—not too hot …

Effects Of Drought On Forests And Rangelands In The United States: A Comprehensive Science Synthesis, James M. Vose, James S. Clark, Charles H. Luce, Toral Patel-Weynand

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

This assessment provides input to the reauthorized National Integrated Drought Information System (NIDIS) and the National Climate Assessment (NCA), and it establishes the scientific foundation needed to manage for drought resilience and adaptation. Focal areas include drought characterization; drought impacts on forest processes and disturbances such as insect outbreaks and wildfire; and consequences on forest and rangeland values. Drought can be a severe natural disaster with substantial social and economic consequences. Drought becomes most obvious when large-scale changes are observed; however, even moderate drought can have long-lasting impacts on the structure and function of forests and rangelands without these obvious …

Biological Invasion Hotspots: A Trait-Based Perspective Reveals New Sub-Continental Patterns, Basil V. Iannone Iii, Kevin M. Potter, Qinfeng Guo, Andrew M. Liebhold, Bryan C. Pijanowski, Christopher M. Oswalt, Songlin Fei

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Invader traits (including plant growth form) may play an important, and perhaps overlooked, role in determining macroscale patterns of biological invasions and therefore warrant greater consideration in future investigations aimed at understanding these patterns. To assess this need, we used empirical data from a national-level survey of forest in the contiguous 48 states of the USA to identify geographic hotspots of forest plant invasion for three distinct invasion characteristics: invasive species richness, trait richness (defined as the number of the five following plant growth forms represented by the invasive plants present at a given location: forbs, grasses, shrubs, trees, and …

Managing Threats To The Urban Forest: From Dutch Elm Disease To Emerald Ash Borer - Learning From Experience, Christopher J. Borman

Doctor of Plant Health Program: Dissertations and Student Research

The urban forest provides important essential services to all municipalities; however, its value is often overlooked. The urban forest contributes to energy savings, environmental benefits, psychological well-being, and social benefits. Managing the urban forest in a sustainable manner is important if we wish to benefit from these services well into the future. Reliable management techniques have been created through previous experiences with pests, and these should be utilized and improved for use on urban forests.

American elm (Ulmus americana L.) was once a major component of the urban forests of North America. In 1927, Dutch elm disease (DED) was …

Traditional Ecological Knowledge: A Model For Modern Fire Management?, Gail Wells

Joint Fire Science Program Digests

For many thousands of years, aboriginal peoples worldwide used fire to manage landscapes. In North America, the frequency and extent of fire (both human caused and natural) were much reduced after European colonization. Fire exclusion became the policy in the United States for most of the 20th century as the country became more settled and industrialized. Past fire exclusion has helped produce landscapes that are highly susceptible to uncharacteristically severe wildfire. An urgent challenge for land managers today is to reduce fire risk through several means, including prescribed burning, without harm to culturally significant resources or human communities. The Joint …

Taming The Software Chaos: True To Its Promise, Iftdss Eases The Burden Of Fuels Treatment Planning—And Does A Lot More Besides, Gail Wells

Joint Fire Science Program Digests

A key problem reported by the fuels treatment planning community is the difficulty and inefficiency of evaluating and then applying many planning tools and applications. Fuels specialists have struggled to find, load, and learn all the different fuels and fire planning models, not to mention the interface of running, adjusting, and inputting data specific to each model without the ability to easily share inputs/outputs between models.

The Interagency Fuels Treatment Decision Support System (IFTDSS) was conceived as a way for users to learn one interface, access a variety of data and models all in one place, and pass data (inputs …

The Fire-Oak Literature Of Eastern North America: Synthesis And Guidelines, Patrick D. Brose, Daniel C. Dey, Thomas A. Waldrop

Joint Fire Science Program Synthesis Reports

Guidelines for using prescribed fire to regenerate and restore upland oak forests, woodlands, and savannas in eastern North America were developed by synthesizing the results of more than 100 scientific publications. The first four chapters provide background information on the values of oak ecosystems, eastern fire history, oak’s adaptations to fire, and the findings of fire-oak research conducted over the past 50 years. The final chapter synthesizes that background information into guidelines that explain how to use prescribed fire to facilitate oak seedling establishment, release oak reproduction from competing mesophytic hardwoods, and rehabilitate open oak woodlands, oak savannas, and scrub …

A Win-Win On Agricultural Lands: Creating Wildlife Habitat Through Agroforestry, Gary Bentrup

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

With increasing demands from society for limited resources, agroforestry will likely be one source of solutions as people find it increasingly necessary to achieve multiple social, economic, and ecological objectives on the same plot of land. Indications are that this is a growing field, so wildlife biologists of the future may want to consider incorporating agroforestry into their career development.

Building Trust, Establishing Credibility, And Communicating Fire Issues With The Public, Josh Mcdaniel

Joint Fire Science Program Digests

With more people than ever living in the vicinity of the wildland-urban interface, communicating wildland fire management activities and building trust with the public is paramount for safety. Although the time and resources it takes to build and maintain the public’s trust may seem daunting, it may be one of the most important factors determining the long-term viability of a fire management program. Trust is built over time through personal relationships with citizens and communities and also by demonstrating competence and establishing credibility. When trust and confidence have been established, managers can enjoy strong support of fire and fuels management …

Temporal Fluctuation Scaling In Populations And Communities, Michael Kalyuzhny, Yishai Schreiber, Rachel Chocron, Curtis H. Flather, Ronen Kadmon, David A. Kessler, Nadav M. Shnerb

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Taylor’s law, one of the most widely accepted generalizations in ecology, states that the variance of a population abundance time series scales as a power law of its mean. Here we reexamine this law and the empirical evidence presented in support of it. Specifically, we show that the exponent generally depends on the length of the time series, and its value reflects the combined effect of many underlying mechanisms. Moreover, sampling errors alone, when presented on a double logarithmic scale, are sufficient to produce an apparent power law. This raises questions regarding the usefulness of Taylor’s law for understanding ecological …

Development And Evaluation Of High Resolution Simulation Tools To Improve Fire Weather Forecasts, Brian K. Lamb, Jason M. Forthofer, Peter R. Robichaud

Joint Fire Science Program Research Project Reports

Fire weather forecasts rely on numerical weather simulations where the grid size is 4 km x 4 km or larger. In areas of complex terrain, this model resolution will not capture the details of wind flows associated with complicated topography. Wind channeling in valleys, wind speed-up over mountains and ridges, and enhanced turbulence associated with rough terrain and tall forest canopies are poorly represented in current weather model applications. A number of numerical wind flow models have been developed for simulating winds at high resolution; however, there are limited observational data available at the spatial scales appropriate for evaluating these …

Exploring How Deliberation On Scientific Information Shapes Stakeholder Perceptions Of Forest Management And Climate Change, Troy E. Hall, Jarod J. Blades

Joint Fire Science Program Research Project Reports

Climate change has resulted in rapid biophysical changes in forests of the western U.S. and has prompted the need for an increased understanding of potential impacts and adaption measures. Land managers, policy makers, and community officials lack locally relevant climate change science and are urgently calling for research to inform management decisions. Nevertheless, a substantial disconnect remains between emerging scientific information and its application in management decisions. Effective action depends on understanding regional and local implications of climate change and open, reasoned discussions about current research and potential mitigation actions among researchers, land managers, and other stakeholders. Boundary objects have …

Fire Effects On Seedling Establishment Success Across Treeline: Implications For Future Tree Migration And Flammability In A Changing Climate, F. S. Chapin Iii, Teresa N. Hollingsworth, Rebecca E. Hewitt

Joint Fire Science Program Research Project Reports

Understanding the complex mechanisms controlling treeline advance or retreat in the arctic and subarctic has important implications for projecting ecosystem response to changes in climate. Changes in landcover due to a treeline biome shift would alter climate feedbacks (carbon storage and energy exchange), ecosystem services such as wildlife and berry habitat, and landscape flammability. Wildfire frequency and extent has increased in the last half-century in the boreal forest and tundra in response to warmer weather and lower precipitation. Invasion of tundra by trees may be facilitated by wildfire disturbance, which exposes new seedbeds, increases nutrient availability immediately post-fire, and creates …

Growth Of Black Walnut In Southeast Nebraska, Benjamin A. Loseke, Dennis M. Adams

Nebraska Forest Service: Publications

Black walnut (Juglans nigra L.), within the family Juglandaceae, is a premier hardwood timber species in the United States. Its native range encompasses most of the eastern U.S., roughly extending from eastern South Dakota and eastern Texas on its western edge to Massachusetts and western Florida in the east (Figure 1). The occurrence and productivity of black walnut on the western edge of its native range, including eastern Nebraska, is largely a function of available water during the growing season. However, black walnut has been extensively planted west and north of its native range. Studies have shown black walnut can …

Nitrogen And Carbon Dynamics In Prairie Vegetation Strips Across Topographical Gradients In Mixed Central Iowa Agroecosystems, Marlin Perez-Suarez, Michael J. Castellano, Randall Kolka, Heidi Asbjornsen, Matthew J. Helmers

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Reductions of nitrogen (N) export from agricultural lands because of changes in specific N stocks andfluxes by incorporation of small amounts of prairie vegetation strips (PVS) are poorly understood. Theprimary objective of this study was to evaluate the effect of the presence and topographical position of PVSon soil and plant carbon (C) and N stocks relative to annual crop and native prairie vegetation. The studywas implemented within three small adjacent watersheds, treated with one of the following cover types:(1) 100% row-crop agriculture (CROP); (2) 20% prairie vegetation (PVS) distributed along the contouracross three topographical positions: upslope, sideslope and footslope position; …

Recovery Of Wolverines In The Western United States: Recent Extirpation And Recolonization Or Range Retraction And Expansion?, Kevin S. Mckelvey, Keith B. Aubry, Neil J. Anderson, Anthony P. Clevenger, Jeffrey P. Copeland, Kimberley S. Heinemeyer, Robert M. Iman, John R. Squires, John S. Waller, Kristine L. Pilgrim, Michael K. Schwartz

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Wolverines were greatly reduced in number and possibly extirpated from the contiguous United States (U.S.) by the early 1900s. Wolverines currently occupy much of their historical range in Washington, Idaho, Montana, and Wyoming, but are absent from Utah and only single individuals are known to occur in California and Colorado. In response, the translocation of wolverines to California and Colorado is being considered. If wolverines are to be reintroduced, managers must identify appropriate source populations based on the genetic affinities of historical and modern wolverine populations. We amplified the mitochondrial control region of 13 museum specimens dating from the late …

Housing Development Erodes Avian Community Structure In U.S. Protected Areas, Eric M. Wood, Anna M. Pidgeon, Volker C. Radeloff, David Helmers, Patrick D. Culbert, Nicholas S. Keuler, Curtis H. Flather

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Protected areas are a cornerstone for biodiversity conservation, but they also provide amenities that attract housing development on inholdings and adjacent private lands. We explored how this development affects biodiversity within and near protected areas among six ecological regions throughout the United States. We quantified the effect of housing density within, at the boundary, and outside protected areas, and natural land cover within protected areas, on the proportional abundance and proportional richness of three avian guilds within protected areas. We developed three guilds from the North American Breeding Bird Survey, which included Species of Greatest Conservation Need, land cover affiliates …
