We are very excited to publicly report that our medusahead (Taeniatherum caput-medusae (L.) Nevski) treatments at Edgewood Preserve have been an enormous success. Our treatments started in 2009 with medusahead infestations spanning some 5-6 acres of the preserve grasslands.  As we completed our 2014 seasonal mow, staff botanists observed only a few individuals throughout the treatment area. Our timed mowing has been extremely successful in reducing the invasive by > 99% according to our annual monitoring which occurs before any mowing.

The Friends of Edgewood have volunteered many hours in order to help reduce resprouts and find new nascent foci and make our efforts even more successful. Thanks to San Mateo County Parks, Friends of Edgewood and all our partners for the great work. We will continue to monitor the site to ensure medusahead is (hopefully) eradicated from the site!
