It’s a bit misleading. Sudden oak death is indeed a serious disease of several oak species, but the disease also impacts over 100 trees, shrubs and ornamentals, making it a concern for our forests, landscapes and the ornamental and nursery industries > More info

Sudden oak is an invasive disease spreading in Northern California forests (and a small portion of Oregon), causing widespread death of infected trees.  Because the pathogen, Phytophthora ramorum, infects several ornamental species, nursery stock in California, Oregon and Washington are subject to regulations for dissemination and sale.

It’s not hard to imagine the consequences if sudden oak death were to spread acroo\ss the U.S.  There are very few management or treatment options that are environmentally safe, practical and effective in forest situations.  Ohio State scientists are studying how to determine how many and which trees are likely to survive in a given areas, based on genetic markers.

The work is being conducted by Pierluigi Bonello, professor in the Department of Plant Pathology at Ohio State, Anna Conrad, graduate student, and their colleagues.  Their work was recently published in Forest Ecology and Management (312:154-160).
