Tuesday, May 19, 7:00 PM. Emily Palmquist and James Holderer: Let’s Talk About Phragmites australis: Changing Distributions of Native, Nonnative, and Gulf Coast Common Reed in Arizona
Emily Palmquist and James Holderer will each discuss their research into common reed (Phragmites australis) and whether the subspecies that are encroaching into the Colorado River in
the Grand Canyon and the Verde River are the native, nonnative, or Gulf Coast subspecies.
Dr. Emily Palmquist is a research ecologist for the USGS Grand Canyon Monitoring and Research Center. She studies the effects of river regulation on riparian vegetation communities, riparian plant population genetics in a restoration context, and physiological responses of riparian plants to flooding and climate.
James Holderer is a research affiliate at the Natural History Institute and a local field botanist. He focuses on special status plant and noxious weed surveys, botanical inventories, and riparian ecology monitoring projects throughout the southwest.
Hybrid meeting: In-person and via Zoom
