Effectiveness Of Forest Management Strategies To Mitigate Effects Of Global Change In South-Central Siberia, Eric J. Gustafson, Anatoly Z. Shvidenko, Robert M. Scheller 2011 US Department of Agriculture Forest Service

Effectiveness Of Forest Management Strategies To Mitigate Effects Of Global Change In South-Central Siberia, Eric J. Gustafson, Anatoly Z. Shvidenko, Robert M. Scheller

Environmental Science and Management Faculty Publications and Presentations

We investigated questions about the ability of broad silvicultural strategies to achieve multiple objectives (reduce disturbance losses, maintain the abundance of preferred species, mitigate fragmentation and loss of age-class diversity, and sequester aboveground carbon) under future climate conditions in Siberia. We conducted a factorial experiment using the LANDIS-II landscape disturbance and succession model. Treatments included varying the size and amount of areas cut and the cutting method (selective or clearcut). Simultaneously, the model simulated natural disturbances (fire, wind, insect out-breaks) and forest succession under projected future climate conditions as predicted by an ensemble of global circulation models. The cutting method …

The assessment team was made up of a diverse group - eight undergraduate PSU students, two graduate teaching assistants and one instructor - representing all ages, interests and fields of study. However, one thing everyone had in common was an interest in learning about collaboration and how it might be used to improve the state of Oregon, the nation and even the world. To that end, everyone participating in the Capstone course hoped to enhance their “Skills for Being an Effective Collaborator.” As this is the first time this course has been offered, we hope our success in meeting its …


Rats As Forest Pests In Southeastern Virginia: Girdling By The Hispid Cotton Rat Sigmodon Hispidus As A Significant Source Of Mortality Of Loblolly Pines (Pinus Taeda) In A Successional Pine Forest, Robyn M. Nadolny 2011 Old Dominion University

Rats As Forest Pests In Southeastern Virginia: Girdling By The Hispid Cotton Rat Sigmodon Hispidus As A Significant Source Of Mortality Of Loblolly Pines (Pinus Taeda) In A Successional Pine Forest, Robyn M. Nadolny

Biological Sciences Theses & Dissertations

The hispid cotton rat (Sigmodon hispidus) is a common field rodent throughout the southeastern US, where volunteer loblolly pine trees (Pinus taeda) invade open space and begin the process of ecological succession from field to pine forest. Recent analysis of the diet of S. hispidus indicates that loblolly pine bark is stripped and eaten during the winter months. In this study, we explored the extent of rodent girdling on a 1.23 ha grid in a successional pine forest in southeastern Virginia. During the winter of 2005 we observed damage to 65% of trees in our study area, with 98% …


A Real-Time Risk Assessment Tool Supporting Wildland Fire Decisionmaking, David E. Calkin, Matthew P. Thompson, Mark A. Finney, Kevin D. Hyde 2011 USDA Forest Service

A Real-Time Risk Assessment Tool Supporting Wildland Fire Decisionmaking, David E. Calkin, Matthew P. Thompson, Mark A. Finney, Kevin D. Hyde

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

Development of appropriate management strategies for escaped wildland fires is complex. Fire managers need the ability to identify, in real time, the likelihood that wildfire will affect valuable developed and natural resources (e.g., private structures, public infrastructure, and natural and cultural resources). These determinations help guide where and when aggressive suppression is required to protect values and when fire may be allowed to burn to enhance ecosystem conditions. This article describes the primary components of the Wildland Fire Decision Support System (WFDSS), a geospatial decision support system developed by the US Forest Service. WFDSS provides state-of-the-art wildfire risk analysis, decision …


Oak Galls: A Strange Biology Indeed!, W. John Hayden 2011 University of Richmond

Oak Galls: A Strange Biology Indeed!, W. John Hayden

Biology Faculty Publications

Anyone who takes the time to look closely at several branches of oak will soon find one or another peculiar anomaly among the leaves and twigs. One can easily find structures resembling Ping-Pong balls, hard knots, fluffy tufts, horns—either single or clustered, or irregular thickenings, to mention just a few possibilities. These abnormal growths are galls, structures caused by the presence of small insect larvae living inside the tissue of the plant. Galls can be found on a wide variety of plants. They are common, for example, on the stems of goldenrods, and the leaves of maples, but oaks are …


High Genetic Diversity And Significant Population Structure In Cedrus Brevifolia Henry, A Narrow Endemic Mediterranean Tree From Cyprus, Nicolas George Homer Eliades, Oliver Gailing, Ludger Leinemann, Bruno Fady, Reiner Finkeldey 2011 Universität Göttingen

High Genetic Diversity And Significant Population Structure In Cedrus Brevifolia Henry, A Narrow Endemic Mediterranean Tree From Cyprus, Nicolas George Homer Eliades, Oliver Gailing, Ludger Leinemann, Bruno Fady, Reiner Finkeldey

Michigan Tech Publications, Part 1

Endemic island plant species with a narrow distribution are often, but not always, linked to low genetic variation within populations and a lack of differentiation among populations. Cedrus brevifolia is a narrow endemic island tree species of Cyprus. Its range is restricted to a single forest, divided into five neighbouring sites. This study, using biparentally inherited nuclear microsatellites and paternally inherited plastid (chloroplast) microsatellites, assessed the genetic variation of C. brevifolia within its sole population and the level of genetic differentiation among formed sites. The results from both markers showed high diversity (nuclear HT = 0. 70; plastid HT = …

Use Of Remote Sensing To Support Forest And Wetlands Policies In The Usa, Audrey L. Mayer, Ricardo D. Lopez 2011 Michigan Technological University

Use Of Remote Sensing To Support Forest And Wetlands Policies In The Usa, Audrey L. Mayer, Ricardo D. Lopez

College of Forest Resources and Environmental Science Publications

The use of remote sensing for environmental policy development is now quite common and well-documented, as images from remote sensing platforms are often used to focus attention on emerging environmental issues and spur debate on potential policy solutions. However, its use in policy implementation and evaluation has not been examined in much detail. Here we examine the use of remote sensing to support the implementation and enforcement of policies regarding the conservation of forests and wetlands in the USA. Specifically, we focus on the “Roadless Rule” and “Travel Management Rules” as enforced by the US Department of Agriculture Forest Service …


Bobcats Do Not Exhibit Rub Response Despite Presence At Hair Collection Stations, Chirstopher E. Comer, Symmank M. E., James C. Kroll 2011 Arthur Temple College of Forestry and Agriculture, Stephen F. Austin State University, Nacogdoches, Texas 75962

Bobcats Do Not Exhibit Rub Response Despite Presence At Hair Collection Stations, Chirstopher E. Comer, Symmank M. E., James C. Kroll

Faculty Publications

We evaluated the detection rate for hair snare sampling for bobcats (Lynx rufus) using colocated hair snares and infrared-triggered cameras at 20 locations on private property in eastern Texas. Hair snares and cameras were placed together at survey stations that included both visual and olfactory attractants. In 1,680 trap-nights we photographically documented 15 visits by bobcats but collected only one bobcat hair sample. Our observations suggested limited rubbing behavior by bobcats at hair snares despite presence at hair collection stations. The explanation for this behavior remains unclear but is consistent with observations of low and variable hair trap …

A Slo Landowners Guide To Natural Resource Regulations, Rob S. Whyte 2011 California Polytechnic State University, San Luis Obispo

A Slo Landowners Guide To Natural Resource Regulations, Rob S. Whyte

Natural Resources Management and Environmental Sciences

Many land owners today are simply unaware of the fact that their private land falls under not only local laws and regulations, but also several state and federal regulations. Unfortunately, this unawareness has often resulted in complete negligence to the land, further leading to the degradation of resources such as creeks and landscapes. “A SLO Land Owners Guide to Natural Resource Regulations” was created to provide the basic knowledge of the different regulations that govern landowners of San Luis Obispo County, with the intent to increase the compliance to the different laws and regulations.

Rangeland Oak Regeneration, Rehabilitation, And Conservation In Varian Ranch, Arroyo Grande, Ca., Tiffany Lappinga, Ivy Ku

Natural Resources Management and Environmental Sciences

Since the majority of oak woodlands are currently under private management, it is important to educate landowners about the importance and value of preserving this unique type of forest, especially in California. The study region takes place in Varian Ranch, Arroyo Grande, California. This project aims to promote the health of rangeland oaks with a three-pronged approach: regeneration, rehabilitation, and conservation. Common issues associated with the decline of oaks include, but are not limited to, invasive/exotic plant species, changes in land use, overgrazing, and soil compaction. This project hopes to address some of these issues, as well as revitalize previous …

Prescribed Fire Effects On The Summer And Fall Herbs Of Mesic Deciduous Forests, Margaret Wilder 2011 Western Kentucky University

Prescribed Fire Effects On The Summer And Fall Herbs Of Mesic Deciduous Forests, Margaret Wilder

Mahurin Honors College Capstone Experience/Thesis Projects

After years of fire suppression, high intensity forest fires were destructive to surrounding areas. Historically, fire was common in the eastern United States, but was suppressed over the past century, and recently has become a major tool in forest management. But to date, there have been no studies on the influence of fire on mesic sites in the eastern United States. Because fire is being reintroduced as a management practice, it is critical to know the influence of fire in this region. This study seeks to understand the influences of fire on summer and fall herbs in the western mesophytic …
