Phytophthora ramorum: integrative research and management of an emerging pathogen in California and Oregon forests.
Phytophthora ramorum, causal agent of sudden oak death, is an emerging plant pathogen first observed in North America associated with mortality of tanoak (Lithocarpus densiflorus) and coast live oak (Quercus agrifolia) in coastal forests of California during the mid-1990s. The pathogen is now known to occur in North America and Europe and have a host range of over 40 plant genera. Sudden oak de...
متن کاملEvaluation of Stem Water Potential and Other Tree and Stand Variables as Risk Factors for Phytophthora ramorum Canker Development in Coast Live Oak
We conducted a case-control study to examine the role of water stress and various other factors on the development of Phytophthora ramorum cankers in symptomatic (case) and symptomless (control) coast live oak (Quercus agrifolia) and tanoak (Lithocarpus densiflorus). Midday stem water potential (SWP) in Q. agrifolia subject trees ranged from – 0.25 to –3.1 megapascals (MPa). SWP was higher (ind...
متن کاملAn Object-Based Classification Approach in Mapping Tree Mortality Using High Spatial Resolution Imagery
In California, a newly discovered virulent pathogen (Phytophthora ramorum) has killed thousands of trees, including tanoak (Lithocarpus densiflorus), coast live oak (Quercus agrifolia), and black oak (Quercus kelloggii). Mapping the distribution of overstory mortality associated with the pathogen is an important part of disease management. In this study, we developed an object-based approach, i...
متن کاملRegeneration of Oaks and Tanoak in Phytophthora ramorum-Affected Forests
Recent mortality in coast live oak (Quercus agrifolia), California black oak (Q. kelloggii), and tanoak (Lithocarpus densiflorus) exceeds historical levels in forests affected by the pathogen Phytophthora ramorum. We assessed the balance between recent mortality and seedling populations in these species to examine the status of regeneration in stands with varying levels of mortality caused by P...
متن کاملPotential Effects of Sudden Oak Death on the Oak Woodland Bird Community of Coastal California
Oak-dependent birds are expected to suffer severe population declines as a result of sudden oak death (SOD). We investigated how the disappearance of two highly SOD-sensitive tree species, tanoak (Lithocarpus densiflorus) and coast live oak (Quercus agrifolia), may in turn affect levels of bird species richness, diversity, and equitability in coastal oak habitats of California. Combining avian ...
