Fuel Reduction Treatment Longevity And Crown Response In Interior Ponderosa Pine Forests Of Northern California, Martin W. Ritchie, Carl N. Skinner, Jianwei Zhang

Joint Fire Science Program Research Project Reports

With increasing interest in fuels treatments to address the high risk of severe fires in the western United States, there is an attendant need to quantify the effectiveness of such treatments. In addition to the immediate effect of reducing levels of combustible material and the attendant impact on fire intensity, resource managers also need to quantify or forecast the longevity of such treatments. Treatments that produce significant, but short-lived reductions in risk of severe wildfire may not be meeting the goals and objectives of managers. This temporal component needs further study and is the subject of this proposal. There are …

Fuel Treatments In Mixed-Pine Forests In The Great Lakes Region: A Comprehensive Guide To Planning And Implementation, Eric Toman, Stanley Gehrt, Charles Goebel, David M. Hix, Roger Williams, Robyn Wilson, Sarah Mccaffrey

Joint Fire Science Program Research Project Reports

Fuel management decisions are made within a larger context of resource management characterized by multiple objectives including ecosystem restoration, wildlife management, commodity production (from timber to less traditional forest products), and provision of recreation opportunities and amenity values. Implementation of fuel treatments is strongly influenced by their perceived influence on and compatibility with overarching management objectives. In some cases these objectives may be complementary while in others they may involve difficult tradeoffs. Such tradeoffs are only further complicated by institutional mandates, limited availability of information, and complex ownership patterns. Like natural resource managers across the U.S., those in the Great …

Structuring Expert Input For A Knowledge-Based Approach To Watershed Condition Assessment For The Northwest Forest Plan, Usa, Sean N. Gordon, Kirsten Gallo

Institute for Sustainable Solutions Publications and Presentations

Assessments of watershed condition for aquatic and riparian species often have to rely on expert opinion because of the complexity of establishing statistical relationships among the many factors involved. Such expert-based assessments can be difficult to document and apply consistently over time and space. We describe and reflect on the process of developing a computer-based decision support application from expert judgments for assessing aquatic and riparian conditions over the 100,000 km2 managed by the US federal government under the Northwest Forest Plan. The decision support system helped structure and document the assessment process and provided consistency and transparency to the …

Coping With Forest Fragmentation: A Comparison Of Colobus Angolensis Palliatus Dietary Diversity And Behavioral Plasticity In The East Sagara Forest, Tanzania., Noah T. Dunham

Honors Projects

Habitat destruction and forest fragmentation are perhaps the largest threats to primate species around the world. While national parks, games reserves, and primate sanctuaries are instrumental in primate conservation, research suggests that some non-governmentally protected forest fragments may also serve as viable habitats for primates. Of course not all primates respond to fragmentation in the same way, but a species’ ability to survive in a fragment relates to 1) home range size 2) degree of frugivory 3) dietary flexibility and behavioral plasticity and 4) ability to utilize matrix habitats. Here I describe these variables in relation to black and white …

Modeling Loblolly Pine Aboveground Live Biomass In A Mature Pine-Hardwood Stand: A Cautionary Tale, D. C. Bragg

Journal of the Arkansas Academy of Science

Carbon sequestration in forests is a growing area of interest for researchers and land managers. Calculating the quantity of carbon stored in forest biomass seems to be a straightforward task, but it is highly dependent on the function(s) used to construct the stand. For instance, there are a number of possible equations to predict aboveground live biomass for loblolly pine (Pinus taeda) growing in southeastern Arkansas. Depending on stem diameter at breast height (DBH), biomass varied considerably between four different prediction systems for loblolly pine. According to the tested models, individual tree oven-dry biomass for a 50 cm DBH loblolly …

Accuracy And User Variation Associated With Slope Measurement Using A Laser Hypsometer, C. Hastings, R. C. Weih Jr., H. O. Liechty, R. Harris

Journal of the Arkansas Academy of Science

Slope measurements are often necessary for assessing features and processes within the natural environment. Land managers often use handheld equipment rather than more complicated surveying equipment in order to measure slopes and to conduct field work efficiently. One type of handheld device used to measure slope is a laser clinometer. In order to determine the accuracy and user error associated with this type of clinometer, slope measurements were taken at multiple locations using two types of equipment: 1) a Haglof Sweden Vertex III Hypsometer with a laser clinometer function and 2) a Topcon GTS-603/AF electronic survey total station which can …

Evaluation Of The Modis Lai Product Using Independent Lidar-Derived Lai: A Case Study In Mixed Conifer Forest, Jennifer L.R. Jensen, Karen S. Humes, Andrew T. Hudak, Lee A. Vierling, Eric Delmelle

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

This study presents an alternative assessment of the MODIS LAI product for a 58,000 ha evergreen needleleaf forest located in the western Rocky Mountain range in northern Idaho by using lidar data to model (R²=0.86, RMSE=0.76) and map LAI at higher resolution across a large number of MODIS pixels in their entirety. Moderate resolution (30 m) lidar-based LAI estimates were aggregated to the resolution of the 1-km MODIS LAI product and compared to temporally-coincident MODIS retrievals. Differences in the MODIS and lidar-derived values of LAI were grouped and analyzed by several different factors, including MODIS retrieval algorithm, sun/sensor …

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

1. Altered global climates in the 21st century pose serious threats for biological systems and practical actions are needed to mount a response for species at risk.

2. We identify management actions from across the world and from diverse disciplines that are applicable to minimizing loss of amphibian biodiversity under climate change. Actions were grouped under three thematic areas of intervention: (i) installation of microclimate and microhabitat refuges; (ii) enhancement and restoration of breeding sites; and (iii) manipulation of hydroperiod or water levels at breeding sites.

3. Synthesis and applications. There are currently few meaningful management actions that will …

A Habitat Overlap Analysis Derived From Maxent For Tamarisk And The South-Western Willow Flycatcher, Patricia York, Paul Evangelista, Sunil Kumar, James Graham, Curtis Flather, Thomas Stohlgren

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

Biologic control of the introduced and invasive, woody plant tamarisk (Tamarix spp, saltcedar) in south-western states is controversial because it affects habitat of the federally endangered South-western Willow Flycatcher (Empidonax traillii extimus). These songbirds sometimes nest in tamarisk where floodplain-level invasion replaces native habitats. Biologic control, with the saltcedar leaf beetle (Diorhabda elongate), began along the Virgin River, Utah, in 2006, enhancing the need for comprehensive understanding of the tamarisk-flycatcher relationship. We used maximum entropy (Maxent) modeling to separately quantify the current extent of dense tamarisk habitat (>50% cover) and the potential extent of …

A Qualitative And Quantitative Analysis Of Risk Perception And Treatment Options As Related To Wildfires In The Usda Fs Region 3 National Forests, Ingrid M. Martin, Wade E. Martin, Carol B. Raish

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

As the incidence of devastating fires rises, managing the risk posed by these fires has become critical. This report provides important information to examine the ways that different groups or disaster subcultures develop the mentalities or perceived realities that affect their views and responses concerning risk and disaster preparedness. Fire risk beliefs and attitudes of individuals and groups from four geographic areas in the Southwest (U.S. Department of Agriculture, Forest Service, Region 3, Arizona and New Mexico) surrounding the Kaibab, Tonto, Santa Fe, and Lincoln National Forests are presented. Using both quantitative and qualitative methods, we collected information from three …

Carrying Capacity For Species Richness As A Context For Conservation: A Case Study Of North American Breeding Birds, Andrew J. Hansen, Linda Bowers Phillips, Curtis H. Flather, Jim Robinson-Cox

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

Aim To demonstrate that the concept of carrying capacity for species richness (S_K) is highly relevant to the conservation of biodiversity, and to estimate the spatial pattern of S_K for native landbirds as a basis for conservation planning.

Location North America.

Methods We evaluated the leading hypotheses on biophysical factors affecting species richness for Breeding Bird Survey routes from areas with little influence of human activities.We then derived a best model based on information theory, and used this model to extrapolate SK across North America based on the biophysical predictor variables. The predictor variables included the …

Overcoming The Obstacles To Sustainability In Ghana, Ashley M. Scott

CMC Senior Theses

For several decades following its independence from Great Britain, Ghana’s policies continued to promote over-extraction of natural resources to the detriment of its economy and rural communities.  Agricultural and forestry policy has gradually evolved to foster more sustainable and equitable practices, as in building partnerships with the private sector to fund infrastructure improvements.  Policy has recently recognized the dire need to adopt agricultural practices and means of forest resource extraction that are compatible with ecological stewardship.  However, many shortcomings are still apparent.  Large logging operations completely disregard forestry regulations with impunity, whereas rural sustenance extractors are severely punished in the …
