On Monday, March 17, the California Department of Fish and Wildlife Habitat Conservation Planning Branch is organizing a two hour lecture by Dr. Joe DiTomaso on the biology, ecology and management of yellow starthistle. The department has not only arranged for the lecture to be presented to participants in attendance, but it will also be available as a live webinar. The presentation will discuss why and how yellow starthistle became so widespread in California and all the possible management strategies, including herbicides, mechanical removal, burning, grazing, and biological control and how these strategies can be best applied to minimize non-target species damage. Dr. DiTomaso will also include an...
