In winter 2023, San Francisco State University researchers began a 3-year study in Edgewood Park on Lyme Disease. The study focuses on monitoring tick hosts, such as deer mice and woodrats, and on testing the efficacy of an oral bait vaccine indicated to limit the spread of the disease.
The study will continue through December 2026. Researchers are permitted to work off-trail within the park. No trail closures related to the study are planned.
