Assessing The Urban Forest Values An Institutional Sector Approach, Anthony M. Rodriguez Ph.D. Jul 2015

Assessing The Urban Forest Values An Institutional Sector Approach, Anthony M. Rodriguez Ph.D.

Anthony M Rodriguez Ph.D.

The presentation is an aspect of an ongoing study that demonstrates and maps the urban forest values. Using ARCGIS the paper will model social change and the potential for expanding or not the natural environment focusing on the values and the projected change based on the sectors position in reference to sustainability and more specifically the urban forest as an artifact to foster positive spatial change.

A major problem in post-fire restoration of semi-arid shrublands dominated by annual bromes is the presence of carryover seed banks that cannot be controlled using conventional methods. These seeds can provide significant competition for seeded species in the years following treatment. We investigated the feasibility of using a naturally occurring seed pathogen, the ascomycete Pyrenophora semeniperda, as a biocontrol organism for eliminating this carryover seed bank. We carried out the necessary technology development to create and apply field inoculum to cheatgrass- or red brome-infested areas (both burned and unburned) at six sites located in three states across two years of …


Tb200: Carbon And Nutrients In Maine Forest Soils, Ivan J. Fernandez Mar 2015

Tb200: Carbon And Nutrients In Maine Forest Soils, Ivan J. Fernandez

Ivan J. Fernandez

Recent public concerns surrounding climate change and greenhouse gas emissions have resulted in a lively debate about approaches to fossil fuel offsets and carbon (C) sequestration in forests. The forest community sees opportunities for the intensification of the use of forests for markets ranging from forest products, such as fuel or fuel feedstock, to a range of new bioproducts. This report provides initial insights from an ongoing effort to synthesize forest soils data for Maine. The specific objectives presented here were (1) to develop descriptive statistics for C and measures of available forms of the essential nutrients N, P, and …


Effects Of Experimental Freezing On Soil Nitrogen Dynamics In Soils From A Net Nitrification Gradient In A Nitrogen-Saturated Hardwood Forest Ecosystem, Frank S. Gilliam, Adam Cook, Salina Lyter Sep 2012

Effects Of Experimental Freezing On Soil Nitrogen Dynamics In Soils From A Net Nitrification Gradient In A Nitrogen-Saturated Hardwood Forest Ecosystem, Frank S. Gilliam, Adam Cook, Salina Lyter

Frank S. Gilliam

This study examined effects of soil freezing on N dynamics in soil along an N processing gradient within a mixed hardwood dominated watershed at Fernow Experimental Forest, West Virginia. Sites were designated as LN (low rates of N processing), ML (moderately low), MH (moderately high), and HN (high). Soils underwent three 7-day freezing treatments (0, –20, or –80 °C) in the laboratory. Responses varied between temperature treatments and along the gradient. Initial effects differed among freezing treatments for net N mineralization, but not nitrification, in soils across the gradient, generally maintained at LN < ML ≤ MH < HN for all treatments. …


Global Effects Of Climate Change On Wildfire: Causal Relationships Of Fire, The Natural Environment And Human Activities, Lindon N. Pronto Dec 2011

Global Effects Of Climate Change On Wildfire: Causal Relationships Of Fire, The Natural Environment And Human Activities, Lindon N. Pronto

Lindon N Pronto

Climate change and human activity is significantly impacting the frequency and severity of wildfires across the globe. Although climate change and human population are the overarching factors affecting wildfires in the current dialogue, the issues are more complex and often not fully understood. These issues range from global temperature increases and severe drought cycles to the relatively new phenomenon of the wildland urban interface (WUI). This is the area where structures are integrated with or immediately surrounded by areas of moderate to high fire risk and are directly linked to fuel types and topographic features. Because climate change is such …
