Investigating Meter Scale Topographic Variation As A Factor Of Monterey Pine (Pinus Radiata) Growing Conditions At Kenneth Norris Rancho Marino Reserve, Cambria, Ca, William J. Meyst

Natural Resources Management and Environmental Sciences

Endemic Monterey pine (Pinus radiata) is limited to three locations in California due to its unique ecological requirements. This project was conducted to investigate spatial growth patterns ofMonterey pine over complex ground surfaces. The coastal hills of Rancho Marino Reserve, Cambria, were surveyed using four 150-m transects to quantify and record ground surface features and growing conditions ofMonterey pine. Changes in elevation of each transect were measured using an Abney level. Linear ground surfaces were found at 86% (344 of 400) of survey nodes. Convex ground surfaces were found at 10.5% of survey nodes (42 of 400). Of the ...

Environmental Science and Management Faculty Publications and Presentations

Wildfires are increasing in severity and frequency in the American West, but there is limited understanding of their economic effects at the community level. We conducted a case study of the impacts of large wildfires in 2008 in Trinity County, California, by examining labor market, suppression spending, and qualitative interview data. We found that the 2008 fires had interrelated effects on several economic sectors in the county. Labor market data indicated a decrease in total private-sector employment and wages and an increase in public-sector employment and wages during the summer of 2008 compared to the previous year, while interviews captured ...


Evaluation Of Methods For Control Of Vegetation In Utility Corridors, George V. Rancea 2014 University of San Francisco

Evaluation Of Methods For Control Of Vegetation In Utility Corridors, George V. Rancea

Master's Projects

Vegetation management programs are now one of the largest budget items for most of the utility companies in the United States. Control methods used in line clearance activities include mechanical trimming, planting management, or use of tree growth regulators (chemicals that suppress the production of gibberellins, the plant hormones that control stem elongation). Choosing the appropriate control method is a decision that vegetation program managers should take based on many factors, like costs, environmental impacts, existing agreements with the landowners, terrain, public perception etc. To find a balance between competing interests – a reliable and economic electric system on one side ...

Review: Pollination, Pollinated And Pollinators Interaction In Pakistan, Mohammad Irshad, Elizabeth Stephen

Journal of Bioresource Management

The agriculture sector is important in the overall economy and export earnings of Pakistan. Pollination is an essential ecosystem service that depends on symbiosis between species, the pollinated and the pollinator. Animal mediated pollination contributes to the sexual production of over 90% species of modern angiosperms. Effective pollination results in increased crop production, quality improvement and more seed production. Many fruits, vegetables, edible oil crops, stimulant crops and nuts are highly dependent on bee pollination. Worldwide value of pollinators is €153 billion (217 billion US dollars). The production value of pollinated dependent crop in Pakistan is quantified to be 1 ...

Bark Beetle-Induced Changes To Crown Fuel Flammability And Crown Fire Potential, Wesley G. Page

All Graduate Theses and Dissertations

Recent outbreaks of mountain pine beetle (Dendroctonus ponderosae Hopkins) in lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) forests and spruce beetle (Dendroctonus rufipennis Kirby) in Engelmann spruce (Picea engelmannii Parry ex Engelm.) forests have affected vast areas across western North America. The highlevels of tree mortality associated with these outbreaks have raised concerns amongst fire managers and wildland firefighters about the effects of the tree mortality on fire behavior, particularly crown fire behavior, as crown fires hinder the ability of firefighters to conduct safe and effective fire suppression operations. Current information regarding crown fire dynamics in recently ...

Assessing Nutrient Limitation In Complex Forested Ecosystems : Alternatives To Large-Scale Fertilization Experiments, Benjamin W. Sullivan, Silvia Alvarez-Clare, Sarah C. Castle, Stephen Porder, Sasha C. Reed, Laura Schreeg, Cory C. Cleveland, Alan R. Townsend

Ecosystem and Conservation Sciences Faculty Publications

Quantifying nutrient limitation of primary productivity is a fundamental task of terrestrial ecosystem ecology, but in a high carbon dioxide environment it is even more critical that we understand potential nutrient constraints on plant growth. Ecologists often manipulate nutrients with fertilizer to assess nutrient limitation, yet for a variety of reasons, nutrient fertilization experiments are either impractical or incapable of resolving ecosystem responses to some global changes. The challenges of conducting large, in situ fertilization experiments are magnified in forests, especially the high-diversity forests common throughout the lowland tropics. A number of methods, including fertilization experiments, could be seen as ...

Environmental Science and Management Faculty Publications and Presentations

Under business as usual (BAU) management, stresses posed by climate change may exceed the ability of Great Lake forests to adapt. Temperature and precipitation projections in the Great Lakes region are expected to change forest tree species composition and productivity. It is unknown how a change in productivity and/or tree species diversity due to climate change will affect the relationship between diversity and productivity. We assessed how forests in two landscapes (i.e., northern lower Michigan and northeastern Minnesota, USA) would respond to climate change and explored the diversityproductivity relationship under climate change. In addition, we explored how tree ...

The most threatened mammal group

on Earth, Madagascar’s five endemic

lemur families (lemurs are found

nowhere else), represent more than 20%

of the world’s primate species and 30% of

family-level diversity. This combination of

diversity and uniqueness is unmatched by

any other country—remarkable considering

that Madagascar is only 1.3 to 2.9% the

size of the Neotropics, Africa, or Asia, the

other three landmasses where nonhuman

primates occur. But lemurs face extinction

risks driven by human disturbance of forest

habitats. We discuss these challenges

and reasons for hope in light of site-specific,

local actions proposed in ...
