Sudden Oak Death has been impacting California's coastal forests for more than a decade. In that time, and in the absence of a centrally organized and coordinated set of mandatory management actions for this disease in California's wildlands and open spaces, many local communities have initiated their own management programs. We present five case studies to(More)
" Sudden Oak Death " (Phytophthora ramorum) is a non-indigenous forest pathogen which causes substantial mortality of coast live oak (Quercus agrifolia) and several other oak tree species on the Pacific Coast of the United States. We estimated the time path of residential property values subject to oak mortality using a dataset that spans more than two(More)
We conducted a research needs assessment (RNA) in 2010 to gather opinions of " experts " and a larger public on research priorities for Phytophthora ramorum, the pathogen that causes sudden oak death in forest trees and Ramorum blight in ornamental plants. We place these 2010 findings in context with findings of similar P. ramorum needs assessments from(More)
In a case study, we evaluated observers' accuracy in detecting Phytophthora ramorum and their ability to estimate percentage of infested area in coast live oak (Quercus agrifolia) stands in California. The study compared visual detection of symptoms on California bay laurel (Umbellularia californica) and oaks with results from three permanent 1-hectare(More)
Sudden oak death (SOD), caused by the non-indigenous forest pathogen Phytophthora ramorum, causes substantial mortality in coast live oak (Quercus agrifolia) and several other oak species on the Pacific Coast of the United States. Quasi-experimental hedonic models examine the effect of SOD on property values with a dataset that spans more than two decades(More)
INTRODUCTION A decade has passed since the plant pathogen Phytophthora ramorum was recognized as the cause of Sudden Oak Death in the United States. In that time, Sudden Oak Death has killed more than an estimated 1 million trees in coastal California and Oregon (Meentemeyer 2008), and the pathogen has been detected in ornamental nurseries over 400 times.(More)
We used bilateral transcranial Doppler to monitor the number of microembolic events (ME) in the left and right middle cerebral arteries of 29 patients during cardiac surgery that required extracorporeal circulation. Based on a previously published study, we hypothesized that the commonly used method of doubling unilateral ME counts to obtain an estimated(More)
