Sudden Oak Death (Phytophthora ramorum) is a pathogen of many different horticultural and native plants. It has been found in the coastal regions of the US. Its infection causes plant death in some species and its presence affects the sale of plants from known infected areas. To date, it has not been found in Wyoming. 195 total samples have been tested, 180 different species have been visually surveyed, and 92 establishments have been inspected in twenty counties in Wyoming.
The Wyoming Sudden Oak Death Survey is conducted through a joint effort between USDA APHIS PPQ and the Wyoming Department of Agriculture. A sample of plant material is collected and sent to the University of Wyoming for initial testing.
