Ellis Margolis is a research ecologist at the New Mexico Landscapes Field Station, a Fort Collins Science Center facility in New Mexico. Ellis received a Ph.D. in Watershed Management from the Laboratory of Tree-Ring Research at the University of Arizona, in Tucson, Arizona. Since joining the USGS in 2015, he has continued his research on the interactions between fire, forests, and drought, and specializes in dendrochronology (the study of tree ring dating). Presently, his research focuses on land use and drought effects on fire regimes and forests in the southwestern U.S. to guide fire regime and forest restoration for watershed management.

Delivering the North American tree-ring fire history network through a web application and an R package
Wildfires are increasing across the western U.S., causing damage to ecosystems and communities. Addressing the fire problem requires understanding the trends and drivers of fire, yet most fire data is limited only to recent decades. Tree-ring fire scars provide fire records spanning 300-500 years, yet these data are largely inaccessible to potential users. Our project will deliver the...
Effects of disturbance and drought on the forests and hydrology of the Southern Rocky Mountains
Climate-related forest disturbances, particularly drought-induced tree mortality and large, high-severity fires from increasingly warm and dry conditions, are altering forest ecosystems and the ecosystem services society depends on (e.g., water supplies). Our research combines long-term place-based ecological data, diverse methods (e.g., paleo, remote-sensing), and networking approaches to...
Using the Past and the Present To Understand Fire Ecology in the Range of the Gunnison Sage-Grouse
Little is known about the role of fire in the sagebrush ecosystem within the range of the Gunnison sage-grouse ( Centrocercus minimus), and fire has been mostly absent from these systems in the 20th century, partially owing to active fire suppression.
The Western Mountain Initiative (WMI)
Western Mountain Initiative (WMI) is a long-term collaboration between FORT, WERC, NOROCK, USFS, NPS, LANL, and universities worldwide to address changes in montane forests and watersheds due to climate change. Current emphases include altered forest disturbance regimes (fire, die-off, insect outbreaks) and hydrology; interactions between plants, water, snow, nutrient cycles, and climate; and...
Post-fire Recovery Patterns in Southwestern Forests
High-severity crown fires in Southwestern dry-conifer forests — resulting from fire suppression, fuel buildups, and drought — are creating large treeless areas that are historically unprecedented in size. These recent stand-replacing fires have reset extensive portions of Southwest forest landscapes, fostering post-fire successional vegetation that can alter ecological recovery trajectories away...
Western Mountain Initiative: Southern Rocky Mountains
Mountain ecosystems of the western U.S. provide irreplaceable goods and services such as water, wood, biodiversity, and recreational opportunities, but their potential responses to projected climatic patterns are poorly understood. The overarching objective of the Western Mountain Initiative (WMI) is to understand and predict the responses—emphasizing sensitivities, thresholds, resistance, and...
