Pitch Canker In The Año Nuevo Monterey Pine Stand: A Retrospective Analysis, Davis Harrison
Pitch Canker In The Año Nuevo Monterey Pine Stand: A Retrospective Analysis, Davis Harrison
Master of Science in Environmental Sciences and Management Projects
Monterey pine (Pinus radiata) is a closed cone conifer tree native to California. Although it is an ecologically and economically valuable tree, there are only five remaining native populations, including, the Año Nuevo stand along California’s central coast. All the remaining native populations have faced threats to their survival, none more than the non-native disease pitch canker (Fusarium circinatum). This fungal infection causes lesions, dead branches, tree top death, and can be potentially fatal to infected trees. This paper is a continuation of a study beginning in 2001, aimed at evaluating the impact of silvicultural management practices on pitch canker …
Post-Czu Lightning Complex Regeneration In The Año Nuevo Monterey Pine Stand, Allison Trutna
Post-Czu Lightning Complex Regeneration In The Año Nuevo Monterey Pine Stand, Allison Trutna
Master of Science in Environmental Sciences and Management Projects
Climate induced increases in fire frequency and severity along with years of fire suppression and drought are predicted for California. The recent CZU Lightning Complex, a high severity wildfire, burned in the Santa Cruz Mountains on California’s central coast and affected an assortment of vegetation, including the survival and recovery of the native Año Nuevo Monterey pine (Pinus radiata (D. Don)) stand. This stand is partially located in Cal Poly’s Swanton Pacific Ranch and has been monitored for over 20 years for the presence of pitch canker (Fusarium circinatum) fungal disease. This study characterized the survival and initial recovery of …
Evaluation Of Red Alder Mortality In The Little Creek Watershed Following The 2009 Lockheed Fire, Dylan Robert Theobald
Evaluation Of Red Alder Mortality In The Little Creek Watershed Following The 2009 Lockheed Fire, Dylan Robert Theobald
Master's Theses
Five hundred eighty red alder along a 2.16 km portion of the Little Creek riparian zone were assessed for mortality following the 2009 Lockheed Fire near Davenport, California. The study area was divided into burn severity zones and every red alder within the riparian zone was observed and assessed for mortality. Height, diameter at breast height (DBH), and age were collected on selected trees. An estimation of red alder large woody debris (LWD) input to Little Creek since a 2010 LWD survey (Smith, 2010) was calculated using average red alder tree dimensions applied to Smalian’s formula (MLNRO, 2011). The mean …
Wildland Urban Interface Assessment Of San Luis Obispo, California, Brian Hanson, Stephen Kadash, Nicholi Mackewicz
Wildland Urban Interface Assessment Of San Luis Obispo, California, Brian Hanson, Stephen Kadash, Nicholi Mackewicz
Natural Resources Management and Environmental Sciences
The purpose of this report is to provide a wildland fire hazard assessment of communities in the city of San Luis Obispo, California, and to identify prescriptions designed to prevent property damage and loss of life in the event of a wildfire. These prescriptions are adopted from established Shelter-In-Place communities who practice fire wise community wildfire prevention.There are eight communities that were identified as being fire prone. Each community had its own set of fire hazard, for example, flammable vegetation against a home, tall dead grass behind structures, or overhanging trees that would prevent an engine from passing. Once the …

Restoration Of A. Fasciculatum At Rocky Canyon Granite Quarry, San Luis Obispo, Ca, Catherine L. Roy
Restoration Of A. Fasciculatum At Rocky Canyon Granite Quarry, San Luis Obispo, Ca, Catherine L. Roy
Master's Theses
The objective of this study was to assess the above-ground factors affecting the establishment and recovery of the dominant chaparral shrub Adenostoma fasciculatum (chamise) on the Rocky Canyon granite mine.
Attempts to restore the California chaparral have been challenging and few successful efforts have been documented. However, the California chaparral can fully recover from fire in as little as 10-15 years. Factors affecting chamise seedling establishment were tested by planting chamise seed in forty eight 1square meter plots managed to test the effects of interspecific competition with native postfire vegetation, post-mining volunteer vegetation, and intraspecific only competition. Plots were managed …
