Forest Structure Of Long-Term Conserved Areas Utilizing Different Strategies On A Continental, Glacial Moraine Formed Island, Christopher Coggin
Forest Structure Of Long-Term Conserved Areas Utilizing Different Strategies On A Continental, Glacial Moraine Formed Island, Christopher Coggin
Masters Theses, 2010-2019
Understanding patterns of forest succession can help advise management plans within New England nature preserves. This study took place on Block Island, 13 miles off the coast of Rhode Island. The island has greater than 200+ years of farming practices. After 1960, conservation groups began reforesting the island using different strategies, such as actively planting with native and exotic tree species, mowing, and preventing further development. In 2018, woody vegetation was inventoried along transects within four reforested sites. Sites were characterized as the following: actively planted with exotic and native tree species and mowed (AP-M), actively planted with exotic and …
Assessment Of The Ponderosa Woodlands In Nebraska's Wildcat Hills: Implications For Juniperus Encroachment And Management, Allie Victoria Schiltmeyer
Assessment Of The Ponderosa Woodlands In Nebraska's Wildcat Hills: Implications For Juniperus Encroachment And Management, Allie Victoria Schiltmeyer
School of Natural Resources: Dissertations, Theses, and Student Research
Ponderosa pine (Pinus ponderosa) is a dominant tree species across western North America. Its eastern distribution includes three populations in western Nebraska. This study assesses the distribution, structure and age of ponderosa pine woodlands in one of those regions, the Wildcat Hills. The Wildcat Hills have escaped severe wildfires seen in recent decades in other ponderosa pine regions. Nevertheless, the Wildcat Hills woodlands face multiple threats including climate change, wildfire, drought, pine beetles, and invasive species. Key to these threats is the stand structure of pine woodlands, which have increased in density across much of ponderosa pine’s range. …
Modeling And Forecasting The Influence Of Current And Future Climate On Eastern North American Spruce-Fir (Picea-Abies) Forests, Caitlin Andrews
Modeling And Forecasting The Influence Of Current And Future Climate On Eastern North American Spruce-Fir (Picea-Abies) Forests, Caitlin Andrews
Electronic Theses and Dissertations
The spruce-fir (Picea-Abies) forest type of the Acadian Region is at risk of disappearing from the United States and parts of Canada due to climate change and associated impacts. Managing for the ecosystem services provided by this forest type requires accurate forecasting of forest metrics across this broad international region in the face of the expected redistribution of tree species. This analysis linked species specific data with climate and topographic variables using the nonparametric random forest algorithm, to generate models that accurately predicted changes in species distribution due to climate change. A comprehensive dataset, consisting of 10,493,619 observations …
Impacts Of Plant Community Changes On Soil Carbon Contents In Northeastern Illinois, Xiaoyong Chen, Karen D'Arcy
Impacts Of Plant Community Changes On Soil Carbon Contents In Northeastern Illinois, Xiaoyong Chen, Karen D'Arcy
Faculty Research and Creative Activity
Land-cover changes not only affect regional climates through alteration in surface energy and water balance, but also affect key ecological processes, such as carbon (C) cycling and sequestration in plant ecosystems. The object of this study was to investigate the effects of land-cover changes on the distribution of soil organic carbon (SOC) contents under four plant community types (deciduous forests, pine forests, mixed pine-deciduous forests, and prairies) in northeastern Illinois, USA. Soil samples were collected from incremental soil depths (0–10, 10–20, 20–30, and 30–50 cm) under the studied plant communities. The results showed that SOC concentration decreased with increases of …
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 …

This book describes the various growth patterns of forests from a mechanistic point of view. Its purpose is to help silviculturists, forest managers, and ecologists understand and anticipate how forests grow and respond to intentional manipulations and natural disturbances. Demands on the forest have been increasing for timber production, wildlife habitat, water protection, recreation, and protection from fires, insects, and diseases. These demands have created an emphasis on prescribing site-specific treatments for individual stands of trees, rather than treating broad areas uniformly
