Goals of the Workshop Series
1. To bring together researchers and managers to assess and share the current state of knowledge regarding perennial pepperweed’s (Lepidium latifolium)ecological impacts, the extent of invasion in the greater Bay Area, and best practices for control.
2. To consider where to focus future funding and research to achieve the most beneficial and sustainable results.
Who Should Attend
Researchers, land managers, regulatory agency personnel, biological consultants, and others interested in this invasive species.
Perennial pepperweed (Lepidium latifolium) is an invasive plant found in the San Francisco Bay Area and throughout California. The California Invasive Plant Council and the California Department of Agriculture list perennial pepperweed as a species of concern because of its ability to expand widely and create dense, monospecific stands that exclude other plants and impact native ecological communities. In the San Francisco Bay Area, perennial pepperweed has successfully invaded a variety of habitats including tidal wetlands, riparian corridors, and agricultural pastures. Several physical, chemical, and biological methods have been used to eradicate or control the spread of this aggressive invader. However, questions about collateral impacts, cost, efficacy, and regional viability of control remain.
Day 1 (September 10, 2008) of the workshop series will focus on the ecological aspects of perennial pepperweed: its history in the region, life cycle, and impacts to native biological communities and endangered species such as the California clapper rail and the salt marsh harvest mouse.
Day 2 (October 29, 2008) will focus on Lepidium control options by reviewing case studies of site-level control and eradication projects, and then exploring regional-level trends and considerations. Both days will include ample opportunity for discussion with experts and colleagues.
A detailed agenda will be available shortly. If you have additional questions, please contact Jessica Olson email@example.com 707.432.0150 x208 or Marina Psaros firstname.lastname@example.org 415.338.3511.
