Philip Higuera is a professor of fire ecology in the Department of Ecosystem and Conservation Sciences at the University of Montana. He directs the PaleoEcology and Fire Ecology Lab, funded largely from the National Science Foundation and Joint Fire Science Program, and he teaches undergraduate and graduate courses in fire and disturbance ecology. Research in his lab spans western North America and broadly addresses interactions among climate, wildfire, ecosystems, and people, across timescales of years to millennia. This work has revealed how fire activity varies with climate change in recent decades and the distant past, and how forest ecosystems respond to past and ongoing changes. Since 2016, collaborative efforts have increasingly focused on understanding wildfire as an integrated social-ecological phenomenon, helping address current societal challenges centered around living with wildfire.

Research in the PaleoEcology and Fire Ecology Lab focuses on understanding the interactions among climate, wildfire, ecosystems, and people over a range of spatial and temporal scales, in the past, present, and future. Understanding ecological change over time integrates projects within the lab, revealing patterns and processes unobservable over human life spans, providing context for ongoing environmental change, and helping anticipate the consequences of future environmental change.
- Current themes:
- Social-ecological resilience to wildfire
- Climate-vegetation-fire interactions across a range of temporal scales in boreal forest, subalpine forest, and arctic tundra ecosystemsAlaskan boreal forests
- Post-fire tree regeneration in Rocky Mountain forests
- Informing terrestrial ecosystem models with paleoecological data
- The lab uses lake sediments, tree rings, observational records, and statistical modeling to study ecosystems from time scales spanning the past several decades to the past 15,000 years.
- Western North Ameirca, focusing in the Rocky Moutnains and Alaska.

Like many UM faculty, being outside in the mountains energizes me and contributes greatly to my quality of life. Exploring the landscapes of our region also directly inspires my research and teaching. Here are a few of the things I love to do, with some highlights:
- Mountain biking, bikepacking, and cyclocross: Missoula has a rich and active cycling community, including many UM faculty. I love participating in local and regional mountain bike and cyclocross races, doing longer bikepacking trips in the region. In June/July 2020 I bikepacked from Superior, MT, to Hailey, ID, along the Wild West Route, which made its way into a news piece on fire management in the time of COVID-19.
- Backcountry skiing and cross-country skiing: I love backcountry telemark skiing and nordic skiing during Montana winters. A local highlight from Feb. 2020 was a one-day ski traverse of Rattlesnake Mountains, from the (base of the) Snowbowl ski area to main Rattlesnake trailhead.
- Hiking and backpacking: From short hikes on Mount Sentinel to multi-day backpacking trips in the region, there are endless areas to explore on foot. A Missoula highlight was a four-day trip leaving from home, biking to the Rattlesnake Wilderness boundary, and then backpacking through the wilderness area. On our last day, we saw wolves attempting kill an elk calf. It was one of the most amazing backcountry scenes I've experienced in over 30 years of exploring mountains, within c. 15 miles of Missoula.
