Grass Valley, (February 5, 2020) – Dr. Jeremy James, will present the next Sierra Science Lecture; The Ecology and Management of Invasive Plant Species in California. Invasive plant species are an agent of and response to environmental change, driving major changes in ecosystem function and biological diversity across the globe. These impacts are particularly pronounced in climatically diverse biodiversity hotspots such as California. This talk focuses on exploring the major ecological drivers of plant invasions in California and the West, how these species alter ecosystem function and biodiversity and also explores the practical approaches and constraints to managing these species across large areas. These topics are highlighted through two case studies including plant invasions in high desert steppes and plant invasions in the Sierra foothills. Finally, we discuss research that evaluates how changes in climate may amplify and shift some of the ecological impacts of invasive plant species in California and the West.

The presentation will be held on Tuesday, February 11, from 6:30 p.m.-7:30 p.m., in the Multipurpose Center, building N12-103, at the Nevada County Campus. Come early and enjoy a meet-and-greet and refreshments at 6:00 p.m.

About our Speaker

Dr. Jeremy James has served as Director of the University of California Sierra Foothill Research and Extension Center since 2012.  His research program centers on understanding climate change impacts on California grasslands and how ranchers that use these systems for livestock production can adapt to these impacts. He also is involved in several national and international projects that are focused on understanding how to restore arid land systems following catastrophic fire or disturbance.  Dr. James completed his doctoral work at the University of California Davis in 2004.  Following this program and prior to his current position he served as a research scientist in eastern Oregon for the USDA Agricultural Research Service.
