Ellie Broadman, PhD

Ellie is a Biologist with the Western Ecological Research Center, working at the Sequoia-Kings Canyon Field Station. 

Prior to joining WERC, Ellie worked as a postdoctoral researcher at the Laboratory of Tree-Ring Research at the University of Arizona, after attending graduate school at Northern Arizona University. Prior to graduate school, Ellie’s first job after receiving her BA was also at the USGS, with the Quaternary Paleoenvironmental Research Laboratory at the Geology, Minerals, Energy, and Geophysics Science Center in Menlo Park, CA.

Her research projects at USGS are focused on forest dynamics in the southern Sierra Nevada, including interactions among wildfire, climate, and drought. She also has a research background in dendrochronology and paleolimnology, and is broadly interested in climate and environmental change in western North America and the North Pacific continental margin.

The Effects of Catastrophic Wildfires on Vegetation and Fuel Loads in the Sierra Nevada of California

In recent years, a number of catastrophic wildfires have fundamentally changed species composition and structure across a large area of the Sierra Nevada of California. These fires leave behind many large, severely burned patches of land where the majority of trees have died. To make informed management decisions, forest managers need to understand the long-term effects of these fires on...

Late Holocene human-environment interactions on the central California coast, USA, inferred from Morro Bay salt marsh sediments

Coastal salt marshes and estuaries provide valuable ecosystem services, yet are susceptible to alteration from human activities. Records of past environmental change in these ecosystems can elucidate relationships between human activities, such as land-use practices, and physical and ecological processes, such as sediment accretion and vegetation changes. To reconstruct the environmental...
