  Problematic and expanding invasive weed problems in the California foothills (DiTomaso) (pdf)

Some of the more problematic invasive plants within the foothills of California are discussed by Dr. DiTomaso, a UC cooperative extension specialist in non-crop weeds. He emphasizes the impacts of invasive plants on wildland ecosystems and native plant communities. His presentation addresses widespread problems such as yellow starthistle and other thistles, tree-of-heaven, perennial pepperweed, brooms, and others. In addition, new expanding weed problems, including stinkwort and oblong spurge, and their potential expansion and impacts are discussed. Dr. DiTomaso is Director of the Weed Research and Information Center at UC Davis, past president of the Weed Science Society of America, and senior author of the definitive two-volume guide to Weeds of California and Other Western States. To find out more about more about Dr. DiTomaso’s work, see:

  Plant Riches of El Dorado County (Ayres) (pdf)

El Dorado County is one of the most botanically diverse places on the planet, home to over 2,300 native plant species. With an area encompassing just 1% of the state it contains almost 30% of the plants native to California. Why is our county so diverse? The answer lies millions of years ago when the Sierra Nevada was uplifted, a process that continues today. The uplift created climatic zones that support seven distinct plant communities each containing hundreds of native plants. Local CNPS botanist Debra Ayres presents a floristic tour of El Dorado County. In our journey, we travel from lower elevation plant communities like grasslands and oak woodlands to mountain forests and alpine rock gardens. Ayres is a long-time resident of El Dorado County, a retired plant ecologist from UC Davis, and is currently the vice president of the El Dorado Chapter of the California Native Plant Society.

  Landscape Analysis and Design (Ayres) (pdf)

Successful landscaping requires an analysis of the site’s physical, biological, and climatic constraints. Questionnaires can identify limiting factors and ways to either accept or mitigate those limitations. Dr. Debra Ayres explains how to analyze all of the many factors one encounters in the foothills when planning a garden. She started her career as a landscape designer and Master Gardener in El Dorado County before she returned to graduate school to become a plant ecologist.
