Researchers at the University of California, Berkeley just completed a two year study of Sudden Oak Death at Point Reyes National Seashore. The study, conducted in collaboration with Seashore staff, examined the extent and severity of the disease.
Sudden Oak Death is a forest disease caused by the non-native pathogen, Phytophthora ramorum. P. ramorum causes substantial mortality in tanoak and coast live oak. It also infects the leaves of, but does not kill, a wide variety of other species including California bay, Douglas-fir, and coast redwood. P. ramorum was first identified in the Bay Area in the mid-1990s, but it was not seen at Point Reyes until 2004. Over the last four years, the disease has been spreading through the coast redwood and Douglas-fir forests of Bolinas and Inverness Ridges.
This study is the first time the extent and effects of Sudden Oak Death have been quantified at Point Reyes. A few key findings include:
The Seashore plans to continue monitoring the spread of Sudden Oak Death and is also participating in a United States Forest Service research program aimed at developing trees that are resistant to this disease.
A copy of the report from this study is posted on the Point Reyes National Seashore's website at http://www.nps.gov/pore/naturescience/diseases_sod.htm. For more information about Sudden Oak Death please visit http://nature.berkeley.edu/comtf/index.html.
