Elise Gornish, Josh Davy, Travis Bean, and I are testing the use of sheep for management of late-season invasive annual grasses. This trial is taking place at five sites at the Hopland Research and Extension Center – two with barb goatgrass, two with medusahead, and one mixed.
Treatments include grazing at boot stage (32 sheep-days on 324 m2), revegetation with native spp vs forage spp, and treatment with low or high rates of glyphosate at tillering, boot stage, and heading. The main plots are 18 m x 36 m including an 18 x 18 grazing enclosure and are replicated three times at each site. All treatments are crossed, for a total of 48 subplots in each main plot.
Grazing was conducted from mid-April to...

Many researchers have attempted to identify the magic combination of elements needed to control the cover and spread of Medusahead (Taeniatherum caput-medusae), an invasive winter annual grass. Individually, these attempts have yielded a variety of outcomes that sometimes suggest opposing strategies for effective weed control. Recently, researchers at UC Cooperative Extension and UC Davis attempted to leverage the collective value of these disparate investigations. They conducted a systematic review in order to understand if any broad conclusions could be drawn to highlight effective techniques for weed management. The authors found that short-term control of Medusahead can be achieved by using most combinations of burning,...
