Accuracy Of Forest Road And Stream Channel Characteristics Derived From Lidar In Forested Mountain Conditions, Russell Alan White Mar 2010

Accuracy Of Forest Road And Stream Channel Characteristics Derived From Lidar In Forested Mountain Conditions, Russell Alan White

Master's Theses

Forest roads and stream channels are mapped using a variety of remote sensing and ground-based techniques. In densely forested areas, conventional remote sensing methods provide limited terrain information, while ground-based surveys can be time-consuming, difficult, and expensive. Light Detection and Ranging (LiDAR) is an airborne remote sensing technology used to create high-resolution digital elevation models (DEMs) of the earth’s surface. This study tests the accuracy of forest road and stream channel features mapped using LiDAR in the steep, forested terrain of California’s Santa Cruz Mountains. A conventional total station survey was used to determine centerline position and elevations along a …


Analysis Of A Pinus Radiata Seed Stock Field In The Native Año Nuevo Stand In California, Christina Brassey Dec 2009

Analysis Of A Pinus Radiata Seed Stock Field In The Native Año Nuevo Stand In California, Christina Brassey

Master's Theses

This study was a part of the international collaborative IMPACT project, which aims to address the potential threat that the pitch canker disease poses to the use of Pinus radiata D. Don in plantations in New Zealand, Australia, and Chile. A field trial of 264 seedstocks was planted adjacent to a native stand of pitch canker infected P. radiata on the central coast of California, and disease symptom development was recorded over a period of 3 years. The results did not correlate with a greenhouse study of the same seedstocks inoculated with Fusarium circinatum Nirenberg & O'Donnell, the causal agent …


Development Of A Laboratory Protocol For The Micropropagation Of Monterey Pines (Pinus Radiata), Año Nuevo Stand, Karen E. Wells May 2009

Development Of A Laboratory Protocol For The Micropropagation Of Monterey Pines (Pinus Radiata), Año Nuevo Stand, Karen E. Wells

Master's Theses

Monterey pine (Pinus radiata), a native tree to California and two Mexican islands, is important both ecologically and economically. Outside native stands, Monterey pines are grown for landscaping in California and on plantations around the world. Pitch canker, a disease caused by the fungus Gibberella circinata Nirenberg & O’Donnell (Fusarium circinatum Nirenberg and O'Donnell) is threatening the survival of Monterey pines. The disease currently affects Monterey pines in many parts of the world including the native stands. No effective chemical or biological control is available but some Monterey pines show resistance to the disease. The purpose of this project was …
