An Evaluation Of Disturbance-Induced Nutrient Changes And Climate Responses Of Loblolly Pine Xylem, Rebecca Lynne Stratton
An Evaluation Of Disturbance-Induced Nutrient Changes And Climate Responses Of Loblolly Pine Xylem, Rebecca Lynne Stratton
Doctoral Dissertations
Dendrochronological techniques are currently limited to the identification of visible fire scars. However, through the development of new dendrochemical techniques, the potential exists to provide insight into a broader array of pyric ecosystems. In addition, the ability to identify historic climate-growth responses provides a better understanding of the conditions under which historic fire regimes occurred.
This study provides the groundwork for the identification of a dendrochemical nutrient fire signature in xylem and identifies the climate-radial growth responses of loblolly pine (Pinus taeda L.) on five sites in the Piedmont of South Carolina. Changes in N, P, K, Ca, Mg, …
But Does It Work? The Impact Of Social Media Use On Interpretive Outcomes And Place Attachments At San Francisco Bay Area Parks, Eric Knackmuhs
But Does It Work? The Impact Of Social Media Use On Interpretive Outcomes And Place Attachments At San Francisco Bay Area Parks, Eric Knackmuhs
Electronic Theses and Dissertations
Many parks are now using social media sites to connect with visitors but little is known about how effective these efforts have been. This study examined the influence of social media use on interpretive outcomes and place attachment. Visitors to four parks in the San Francisco Bay Area were surveyed twice, once as they exited the park (n = 529) and a second time via email (n = 216) six to ten weeks after visiting. In both surveys, respondents were asked how they use social media to experience parks and to what extent they experienced interpretive outcomes (intellectual and emotional …
Analyzing Spring Freeze Impacts On Deciduous Forest Productivity Using Modis Satellite Imagery, Karl Lintvedt
Analyzing Spring Freeze Impacts On Deciduous Forest Productivity Using Modis Satellite Imagery, Karl Lintvedt
Graduate Theses and Dissertations
The impacts of an April 2007 spring freeze event on the productivity of deciduous broadleaf forest were analyzed using geographic information system (GIS) tools. Forest productivity was modeled using the Enhanced Vegetation Index (EVI), as recorded by the Moderate Resolution Imaging Spectroradiometer (MODIS) satellite sensor. Measures of spatial autocorrelation were used to quantify the degree of spatial congruence between a map depicting the severity of the freeze event, and maps modeling forest productivity throughout the year. The results show a geographic correlation between the unseasonably low minimum temperatures sustained during the freeze and the unusually low forest productivity that followed. …
Classifying And Mapping Diversity In A Species-Poor System: The Mangrove Meta-Community Of Laguna Chacahua National Park, Oaxaca, Mexico, Elizabeth Kay Weisgerber
Classifying And Mapping Diversity In A Species-Poor System: The Mangrove Meta-Community Of Laguna Chacahua National Park, Oaxaca, Mexico, Elizabeth Kay Weisgerber
Master's Theses
ABSTRACT
Classifying and Mapping Diversity in a Species-Poor System: the mangrove meta-community of Laguna Chacahua National Park, Oaxaca, Mexico
by
Elizabeth Kay Weisgerber
Both field transects and imagery grid plots were analyzed with the goal of creating a community classification map for the mangrove forest of Parque Nacional Lagunas de Chacahua. In total, data was collected in 49 sites throughout the park, recording measures such as DBH, basal area, estimated dominance, frequency, cover and relative dominance. Field locations were marked and georeferenced with a GPS and grid plots overlaid on satellite imagery of the park were generated via a random …
Bringing Biodiversity To Development: Perceptions Of Integrating Eucalyptus And Forest-Corridors Around The Serra Do Brigadeiro, Brazil, Maggie R Stevens
Bringing Biodiversity To Development: Perceptions Of Integrating Eucalyptus And Forest-Corridors Around The Serra Do Brigadeiro, Brazil, Maggie R Stevens
Masters Theses
The Atlantic Forest of south-eastern Brazil is a hot-spot for biodiversity and should be conserved. It is also at the center of the largest municipalities in Brazil and therefore has a severely fragmented landscape. Iracambi, a working farm near the Serra do Brigadeiro state park in Minas Gerais, is working for conservation in an area of intense agricultural production and expanding forestry industry. Most households in this rural area have some amount of eucalyptus on their property and consequently the director of Iracambi is developing the preliminary foundation for a forest corridor program comprised of primarily eucalyptus with the goal …
Utilization Of Geographic Information System For Research, Management, And Education In The Natural Resources Management Department At California Polytechnic State University, San Luis Obispo, David In Yun
Master's Theses
Geographic Information System (GIS) is “an organized collection of computer hardware, software, geographic data, and personnel designed to efficiently capture, store, update, manipulate, analyze, and display all forms of geographically referenced information” (ESRI, 1997a). The Natural Resources Management Department at California Polytechnic State University, San Luis Obispo, California, hereafter NRM, was one of the early users of GIS technology. Although GIS was primarily used as an educational tool, it was also used for cataloging and displaying resource information for management planning and research projects. As the computing technology advanced, GIS became more powerful and easier to use. NRM faculty and …
Evaluation And Utilization Of The Continuous Forest Inventory System At Swanton Pacific Ranch, Dominic Ali, Reid Cody
Evaluation And Utilization Of The Continuous Forest Inventory System At Swanton Pacific Ranch, Dominic Ali, Reid Cody
Natural Resources Management and Environmental Sciences
Five Continuous Forest Inventories (CFI) and one Senior Project Inventory (Piper et al. 1989) at Swanton Pacific Ranch in Davenport, CA were compiled and standardized to be formatted for input into Forest and Stand Evaluation Environment (FORSEE) growth and yield modeling software. Data from field books and Excel spreadsheets located on the Cal Poly Natural Resources Management Department hard drive was transcribed into a Microsoft Excel database. Data sources and authenticity were verified by cross-referencing plot data from multiple sources, associated senior project reports, and location on the Swanton grid system. An additional summary spreadsheet was made to help users …
