Emily Palmquist


Emily Palmquist is a plant ecologist with the Southwest Biological Science Center, Grand Canyon Monitoring and Research Station and a PhD candidate at Northern Arizona University. Her current research projects focus on the impact of dams and river regulation on the composition and dominance of riparian vegetation, riparian plant population genetics in a restoration context, and physiological responses of riparian plants to flooding and climate. Most of her projects focus on plants of the Colorado River downstream of Glen Canyon Dam.

Emily received her B.S. in Environmental Science and English at Carroll University in Waukesha, WI and her M.S. in Biology at Northern Arizona University in Flagstaff, AZ in 2010. Her Master’s thesis focused on the population genetics, taxonomic placement, and biogeographic history of a rare, Colorado Plateau endemic plant species, alcove deathcamas (Anticlea elegans subsp. vaginata).

Emily moved to the Southwest in 2006 after a variety of seasonal plant ecology positions in Minnesota, Indiana, and Western Australia. Since then, she has worked in Utah, Arizona, and New Mexico assisting with research on rare plants, dryland plant ecology, spring vegetation, grazing, and riparian vegetation. Emily has been working in the Grand Canyon region since 2011, which has included conducting upland and riparian long-term vegetation monitoring and grazing assessments.
