Hardcore Natural History: The Price of Pesticides

Join us for a discussion of recent research on pesticide contamination of milkweed in California's Central Valley led by Sarah Hoyle. A research team including Xerces Society staff and scientists from University of Nevada, Reno, sampled milkweed plants from various landscapes in the Central Valley and analyzed them for pesticide residues. They found widespread contamination of milkweed at levels that could harm monarch caterpillars. Sarah will review their research and its implications for monarch conservation.
