She has also developed ways to evolve management techniques of forest ecosystems to improve the ability to protect them against climate change.
[4] CIRMOUNT is an organization founded by Millar and her colleagues in 2004 which aims to serve as a medium for researchers studying mountains of western North America to collaborate with each other and further scientific understanding of how climate change is affecting their ecosystems.
[5] She is also a lead operative of the North American Global Observation Initiative in Alpine Environments (GLORIA) Great Basin Chapter, which she founded in 2004 through her involvement in CIRMOUNT.
[6] Millar's research is focused on the effects of climate change and its impact on various aspects of temperate forests[7] and alpine ecosystems.
She has learned that Americans pikas will be able to withstand a wider range of climates than previously thought, by taking advantage of subsurface habitats.
