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 …

Variability In Soil Climate And Respiration On Managed Timber Stands: A Case Study In Southwest Oregon, Scott Pensky, Adrian Gallo
Variability In Soil Climate And Respiration On Managed Timber Stands: A Case Study In Southwest Oregon, Scott Pensky, Adrian Gallo
Natural Resources Management and Environmental Sciences
Thinning of forested lands and timber stands in the Pacific Northwest have taken place for centuries with a limited understanding of how the alterations may affect ecosystem functions. The goal of this study was to examine the soil climate and microbial activity on a seasonal timescale of thinning practices examined at different stages of succession. Two timber stands in Southwestern Oregon within the Grayback Creek Watershed were chosen because of identical forest management techniques separated by a 10-year treatment interval (40% variable density thinning). Field methods and equipment measured canopy coverage, soil moisture and temperature at 3 depths (5, 15, …
Rangeland Oak Regeneration, Rehabilitation, And Conservation In Varian Ranch, Arroyo Grande, Ca., Tiffany Lappinga, Ivy Ku
Rangeland Oak Regeneration, Rehabilitation, And Conservation In Varian Ranch, Arroyo Grande, Ca., Tiffany Lappinga, Ivy Ku
Natural Resources Management and Environmental Sciences
Since the majority of oak woodlands are currently under private management, it is important to educate landowners about the importance and value of preserving this unique type of forest, especially in California. The study region takes place in Varian Ranch, Arroyo Grande, California. This project aims to promote the health of rangeland oaks with a three-pronged approach: regeneration, rehabilitation, and conservation. Common issues associated with the decline of oaks include, but are not limited to, invasive/exotic plant species, changes in land use, overgrazing, and soil compaction. This project hopes to address some of these issues, as well as revitalize previous …
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 …
Mill Creek Management Plan, Joey A. Gentry
Mill Creek Management Plan, Joey A. Gentry
Natural Resources Management and Environmental Sciences
The goal of this study is to conduct a management plan for the Mill Creek property. This will be obtained through meeting the landowner objectives concerning: wildlife with habitat enhancements, recreation locations, and the forest growth potential pertaining to different areas of the property. 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 …
