This plan will also offer suggestions and guidelines to maximize the use of the property. Including a collection of flora, fauna, and health related issues in the appendices for identification. The site condition on the property is very poor, and as a result the growth rate for this area is slow. It is recommended that the ...


Impact Of Revised And Potential Future Albedo Estimates On Ccsm3 Simulations Of Growing-Season Surface Temperature Fields For North America, Warren E. Heilman, David Y. Hollinger, Xiuping Li, Xindi Bian, Shiyuan Zhong 2010 USDA Forest Service

Impact Of Revised And Potential Future Albedo Estimates On Ccsm3 Simulations Of Growing-Season Surface Temperature Fields For North America, Warren E. Heilman, David Y. Hollinger, Xiuping Li, Xindi Bian, Shiyuan Zhong

USDA Forest Service / UNL Faculty Publications

Recently published albedo research has resulted in improved growing-season albedo estimates for forest and grassland vegetation. The impact of these improved estimates on the ability of climate models to simulate growing-season surface temperature patterns is unknown. We have developed a set of current-climate surface temperature scenarios for North America using the Community Climate System Model – Version 3 (CCSM3). Simulation results suggest that modifications to the default CCSM3 radiative parameters that are consistent with more recent accurate measurements of albedo values for grasslands and needle-leaf deciduous trees (NDTs) can reduce the overall growing-season surface temperature bias over North America in CCSM3 ...


Current And Future Molecular Approaches To Investigate The White Pine Blister Rust Pathosystem, B. A. Richardson, A. K. M. Ekramoddoulah, J.-J. Liu, M.-S. Kim, N. B. Klopfenstein 2010 USDA Forest Service

Current And Future Molecular Approaches To Investigate The White Pine Blister Rust Pathosystem, B. A. Richardson, A. K. M. Ekramoddoulah, J.-J. Liu, M.-S. Kim, N. B. Klopfenstein

USDA Forest Service / UNL Faculty Publications

Molecular genetics is proving to be especially useful for addressing a wide variety of research and management questions on the white pine blister rust pathosystem. White pine blister rust, caused by Cronartium ribicola, is an ideal model for studying biogeography, genetics, and evolution because: (1) it involves an introduced pathogen; (2) it includes multiple primary and alternate hosts occurring in large, relatively undisturbed ecosystems; (3) some hosts exhibit endemic resistance; and (4) the disease interaction is long enduring. Molecular techniques are used to investigate population genetics, phylogenetics, hybrids, and proteomics in white pine (Pinus, subgenus Strobus) and blister rust (Cronartium ...

Blister Rusts In China: Hosts, Pathogens, And Management, X. Y. Zhang, Q. Lu, R. A. Sniezko, R. Q. Song, G. Man

USDA Forest Service / UNL Faculty Publications

China has 12 taxa of white pines (subgenus Strobus), including species of wide distribution valuable to plantation forestry and species of rare endemics only distantly related to other white pines. The most important forest diseases of these white pines are caused by the blister rust fungi of the genus Cronartium that alternate to telial host species of Ribes and Pedicularis. The most serious infestations have occurred in southwestern China on Pinus armandii and in northeastern China on P. koraiensis. The blister rust pathogen on P. armandii has usually been identified as Cronartium ribicola. Several lines of evidence, however, imply this ...

Effects Of Splat® Gm Sprayable Pheromone Formulation On Gypsy Moth Mating Success, Ksenia S. Onufrieva, Kevin W. Thorpe, Andrea D. Hickman, Patrick C. Tobin, Donna S. Leonard, E. Anderson Roberts

USDA Forest Service / UNL Faculty Publications

Several integrated pest management programs rely on the use of mating disruption tactics to control insect pests. Some programs specifically target non-native species, such as the gypsy moth, Lymantria dispar (L.) (Lepidoptera: Lymantriidae).We evaluated SPLAT ® GM, a new sprayable formulation of the gypsy moth sex pheromone disparlure, for its ability to disrupt gypsy moth mating. The study was conducted in 2006, 2007, and 2008 in forested areas in Virginia, USA. Mating success of gypsy moth females was reduced by >99% and male moth catches in pheromone-baited traps by >90%, in plots treated with SPLAT ® GM at dosages ranging from ...


Population Trends In Northern Spotted Owls: Associations With Climate In The Pacific Northwest, Elizabeth M. Glenn, Robert G. Anthony, Eric D. Forsman 2010 Oregon State University

Population Trends In Northern Spotted Owls: Associations With Climate In The Pacific Northwest, Elizabeth M. Glenn, Robert G. Anthony, Eric D. Forsman

USDA Forest Service / UNL Faculty Publications

We used reverse time capture-mark-recapture models to describe associations between rate of population change (λ) and climate for northern spotted owls (Strix occidentalis caurina) at six long-term study areas in Washington and Oregon, USA. Populations in three of six areas showed strong evidence of declining populations, while populations in two additional areas were likely declining as well. At four areas, λ was positively associated with wetter-than-normal conditions during the growing season, which likely affects prey availability. Lambda was also negatively associated with cold, wet winters and nesting seasons, and the number of hot summer days. The amount of annual variation ...


Regeneration Response And Seedling Bank Dynamics On A Dendroctonus Rufipennis-Killed Picea Engelmannii Landscape, R. Justin DeRose, James N. Long 2010 Utah State University

Regeneration Response And Seedling Bank Dynamics On A Dendroctonus Rufipennis-Killed Picea Engelmannii Landscape, R. Justin Derose, James N. Long

Aspen Bibliography

Question: How does regeneration response to a host- specific, high-severity, infrequent Dendroctonus rufipennis outbreak differ from our conceptualization of high-severity, infrequent/low-severity, frequent disturbance regimes in Picea engelmannii - Abies lasiocarpa communities? Location: Southern Utah, USA. Methods: One hundred and seven plots across a high- elevation P. engelmannii forest were sampled to re- construct pre-outbreak overstory and seedling bank densities, and calculate their associated metrics of diversity. Decade of establishment by seedling bank trees indicated ‘‘chronic’’ and ‘‘pulse’’ regenerators. Results: The post-outbreak overstory and seedling bank were dominated by A. lasiocarpa. Although Pinus flexilis, Pinus ponderosa, Picea pungens, and Psuedotsuga menziesii ...


Two Year Response Of A Woody Biofuel Plantation To Intensive Management On A Reclaimed Surface Mine In Eastern Kentucky, Joshua Scott Brinks 2010 University of Kentucky

Two Year Response Of A Woody Biofuel Plantation To Intensive Management On A Reclaimed Surface Mine In Eastern Kentucky, Joshua Scott Brinks

University of Kentucky Master's Theses

The establishment of intensively managed woody energy crops on reclaimed surface mine lands provides an opportunity to diversify domestic biomass sources, while increasing the productivity and economic value of underutilized land. Our objective is to test the effect of fertilization and irrigation on the growth, survival, biomass accumulation, biomass allocation, leaf area, and nutrient dynamics of American sycamore (Platanus occidentalis L.) and black locust (Robinia pseudoacacia L.) planted on a reclaimed surface mine. In 2008, replicated plantings of sycamore and black locust were established on the Big Elk mine in eastern Kentucky. Treatments tested include annual granular fertilizer applications of ...


Family Ties: Mainstream Environmentalists' Understanding Of Radical Environmentalism In America, Zachary W. Ezor 2010 Colby College

Family Ties: Mainstream Environmentalists' Understanding Of Radical Environmentalism In America, Zachary W. Ezor

Honors Theses

Environmentalism in the United States manifests itself in numerous ways. While American environmentalists have been grouped into broad camps over the years, observers have struggled to accurately classify the different components of the movement. Lately, environmentalists have been characterized based on their chosen modus operandi. Environmentalists who employ typical interest group tactics of policy advocacy and accept the notion of political compromise can generally be called 'mainstream.' Alternatively, those environmentalists who employ non-conventional strategies like direct action and take a no-compromise stance on environmental issues are typically described as 'radical.' Despite these distinctions, both radical and mainstream environmentalists are parts ...

The State Of The System And Steps Toward Resilience Of Disturbancedependent Oak Forests, Tricia G. Knoot, Lisa A. Schulte, John C. Tyndall, Brian J. Palik

Natural Resource Ecology and Management Publications

Current ecological, economic, and social conditions present unique challenges to natural resource managers seeking to maintain the resilience of disturbance-dependent ecosystems, such as oak (Quercus spp.) forests. Oak-dominated ecosystems throughout the U.S. have historically been perpetuated through periodic disturbance, such as fire, but more recently show decline given shifting disturbance regimes associated with human land management decisions. We characterized the state of the social-ecological oak forest ecosystem in the midwestern U.S. through the perspectives of 32 natural resource professionals. Data from interviews with these change agents provided an integrative understanding of key system components, cross-scale interactions, dependencies, and ...

Potential Applications Of Randomised Graph Sampling To Invasive Species Surveillance And Monitoring., Mark J. Ducey, Kathleen M. O'Brien 2010 University of New Hampshire

Potential Applications Of Randomised Graph Sampling To Invasive Species Surveillance And Monitoring., Mark J. Ducey, Kathleen M. O'Brien

Natural Resources and the Environment Scholarship

Abstract

Many invasive plants and animals disperse preferentially through linear networks in the landscape, including road networks, riparian corridors, and power transmission lines. Unless the network of interest is small, or the budget for surveillance is large, it may be necessary to draw inferences from a sample rather than a complete census on the network. Desired features of a surveillance system to detect and quantify invasion include: (1) the ability to make unbiased statements about the spatial extent of invasion, the abundance of the invading organism, and the degree of impact; (2) the ability to quantify the uncertainty associated with ...


Evaluating Federal Urban Forestry Performance Measures In Massachusetts (U.S.A.), Mollie E. Freilicher 2010 University of Massachusetts Amherst

Evaluating Federal Urban Forestry Performance Measures In Massachusetts (U.S.A.), Mollie E. Freilicher

Masters Theses 1911 - February 2014

In 2006, the U.S. Forest Service implemented performance measures to evaluate urban forestry management in communities in each state. The Forest Service implemented these measures under its Community Accomplishment Reporting System (CARS). To achieve four CARS measures that pertain to management, communities must have a management plan, professional staff, tree ordinances, and an advisory or advocacy organization. It is unclear whether attaining the CARS measures reflects the status of the urban forest itself. We analyzed street tree inventories from communities in Massachusetts that met the CARS measures. We considered the net gain or loss in the number of street ...


Nitrogen Dioxide In The Urban Forest: Exposure And Uptake, Tanner B. Harris 2010 University of Massachusetts Amherst

Nitrogen Dioxide In The Urban Forest: Exposure And Uptake, Tanner B. Harris

Masters Theses 1911 - February 2014

Nitrogen dioxide (NO2) levels were measured inside and adjacent to canopies of urban trees in Springfield, MA, over two growing seasons. Nitrogen dioxide levels were consistently and significantly higher inside tree canopies compared to levels outside. During the second growing season, ozone (O3), temperature, and relative humidity (RH) were also measured using samplers co-located with the NO2 samplers. Ozone levels were significantly lower inside the canopy whereas temperatures were higher inside the canopy, and RH was not different between inner and outer canopy locations. The results corroborate theoretical models predicting elevated NO2 and depressed O3 levels inside tree canopies based ...

The Effects Of The 1996 U.S.-Canada Softwood Lumber Agreement On The Industrial Users Of Lumber: An Event Study, Nisha Malhotra, Sumeet Gulati

Nisha Malhotra

In this article, we analyze whether the Softwood Lumber Agreement between the United States and Canada imposed significant economic costs on industries that use softwood lumber in the United States. To ascertain this impact, we use an event study. Our event study analyzes variations in the stock prices of lumber-using firms listed at the major stock markets in the United States. We find that the news of events leading to the Softwood Lumber Agreement had significant negative impacts on the stock prices of industries using softwood lumber. The average reduction of stock prices for our sample of firms was approximately ...
