This spread of habitats and more moderate climate means the ecosystem hosts songbirds, wildflowers, and plants in abundance.

The abundance of flora and fauna in the subalpine is nothing short of extraordinary, subject to the availability of summer rain, sporadic fire, and a fresh supply of snowmelt.

We study microbes living in the highest glaciers and talus fields of Niwot Ridge, to better understand how microbes survive in extreme environments. We also study microbes as critical players in the cycling of nutrients and plant resource uptake, to better understand how this web of interactions buffers of accelerates physical change. https://static1.squarespace.com/static/5c4f6792ec4eb7c7c4186cc0/5c51f8f8758d466106bfaaaf/5c65d6bb448c8aa50417ddc6/1548876361789/ Major Research Topics - Plant Ecology Plants are the living foundation of ecosystems, and mountains are no exception. The ways that energy, carbon, and nutrients travel through the mountains depends on how and where plants grow. We study changes in plant ecology over time and what that means for the mountains that depend on them. https://images.squarespace-cdn.com/content/v1/5c4f6792ec4eb7c7c4186cc0/1556745466512-8BA0DBBAIIZUO43RXK5N/GL4_fall.jpg Major Research Topics - Limnology High-elevation lakes are focal points of the mountain landscape. There, we find food webs of phytoplankton and zooplankton that nimbly respond to ice off, flushes of cold snowmelt water, and warmer conditions at the height of the summer. We study long-term shifts in these aquatic communities as a window into the future of life on the mountain. https://images.squarespace-cdn.com/content/v1/5c4f6792ec4eb7c7c4186cc0/1555274445660-ZG6BFSEERXER0TWGYS4C/Como+creek.jpg Major Research Topics - Hydrology High-elevation ecosystems function like water towers. They store snow during the winter, and release snowmelt in the spring. Decades of water monitoring show how atmospheric deposition and permafrost thaw can affect the export of many constituents found in our water, such as nitrate, sulfate, and carbon. https://images.squarespace-cdn.com/content/v1/5c4f6792ec4eb7c7c4186cc0/1555357485548-U8U7ANX5STVR3LCWUTS9/Navajo_28July2002.jpg Major Research Topics - Geomorphology Mountain ecosystems develop according to the physical processes of weathering, erosion, and sediment movement. We study the origin and evolution of topographic features at and surrounding Niwot Ridge, as well as how this geomorphology acts as a template on which biological processes develop and change. https://images.squarespace-cdn.com/content/v1/5c4f6792ec4eb7c7c4186cc0/1555275071059-D88JILG4TSCPIHFIX4Z9/Marr53.jpg Major Research Topics - Atmospheric Science At the highest points on the tundra, we collect data on the Earth's atmosphere, climate, and interactions with the Earth’s surface. We measure atmospheric deposition and pollution, use flux towers to understand land-air exchange of carbon and energy, and track changes in temperature and precipitation — many of these records making history as the longest running measures in the continental US. https://images.squarespace-cdn.com/content/v1/5c4f6792ec4eb7c7c4186cc0/1555275147792-67KNOYSO34SFZOATZHI1/Rocky+harey+picture+%28show%29.jpg Major Research Topics - Animal Ecology Mountain animals live at the edge of environmental extremes, and climate change is making their persistence even more uncertain. Studies of animals like pika, marmots, and bees provide indicators of environmental change through shifts in their abundance and distribution over time. https://nwt.lternet.edu/contact-us daily 0.75 2025-10-17 https://images.squarespace-cdn.com/content/v1/5c4f6792ec4eb7c7c4186cc0/cf968e38-2327-4612-bd00-5a3693dc1523/Home_header_credit-Jeff%252BMitton.jpg Contact Us https://images.squarespace-cdn.com/content/v1/5c4f6792ec4eb7c7c4186cc0/1557328587518-5L4K7JK2BSJR2E0TXGRZ/43595963_1862730757115013_8550911292242657280_o%2B%25281%2529.jpg Contact Us https://images.squarespace-cdn.com/content/v1/5c4f6792ec4eb7c7c4186cc0/1557328631553-5WC64PSDW05DZBI4XJHG/24059370_1499362330118526_7638362147364456098_o.jpg Contact Us https://nwt.lternet.edu/news-events daily 0.75 2025-10-17 https://nwt.lternet.edu/k-12-education-outreach-programs daily 0.75 2025-03-26 https://images.squarespace-cdn.com/content/v1/5c4f6792ec4eb7c7c4186cc0/1554941482407-YQB2KFRQPTM19UF39WQX/DSC_0378.jpg K - 12 Education and Outreach https://images.squarespace-cdn.com/content/v1/5c4f6792ec4eb7c7c4186cc0/1573062822193-FPKLY2JLPLXY0PSXL2UK/DSC_2011.JPG K - 12 Education and Outreach https://images.squarespace-cdn.com/content/v1/5c4f6792ec4eb7c7c4186cc0/1554941482407-YQB2KFRQPTM19UF39WQX/DSC_0378.jpg K - 12 Education and Outreach - We connect our research with the public through K-12 education and outreach partnerships.

In the alpine, a step increase in precipitation occurred in the 1980s, reflecting a decadal shift in atmospheric circulation (Kittel et al., 2015). After this change is taken into account, there is no significant trend in annual precipitation across alpine record. Seasonal precipitation over the recent decades tells a different story: winter precipitation has been higher than average and summer precipitation has been lower than average.
