Baron was President of the Ecological Society of America in 2014, is a Certified Professional Ecologist, and a Fellow of the ESA. She was named a Woman of Vision in 2015 by Colorado Women of Influence for her work advancing women’s role in science. Baron is active in US National Climate Assessment efforts, has given testimony to Congress on western acid rain and climate change issues, and was Editor-in-Chief of Issues in Ecology, an Ecological Society of America publication for non-scientists from 2009-2012. She is founder and Principal Investigator of the Loch Vale Watershed long-term monitoring and research program in Rocky Mountain National Park, an instrumented catchment with 33 years of continuous records.

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...
Western Mountain Initiative: Central Rocky Mountains
Mountain ecosystems of the western U.S. provide irreplaceable goods and services such as water, wood, biodiversity, and recreational opportunities, but their responses to global changes are poorly understood. The overarching objective of the Western Mountain Initiative (WMI) is to understand and predict the responses, emphasizing sensitivities, thresholds, resistance, and resilience, of...
Adding a nitrogen footprint to Colorado State University’s sustainability plan
As a large land grant university with more than 32,000 students, Colorado State University has both on-campus non-agricultural and agricultural sources of nitrogen (N) released to the environment. We used the Nitrogen Footprint Tool to estimate the amount of N released from different sectors of the university for the CSU 2014 academic year. The...
Kimiecik, Jacob; Baron, Jill S.; Weinmann, Timothy; Taylor, Emily Land before water: The relative temporal sequence of human alteration of freshwater ecosystems in the conterminous United States
Human alteration of ecosystems prior to Euro-American contact in the area that became the conterminous United States disproportionately affected terrestrial systems compared to freshwater ecosystems, primarily through the use of fire and agriculture in some regions of the United States. After circa 1600 AD, trapping of beaver, along with intensive...
Wohl, Ellen; Lininger, Katherine B.; Baron, Jill S. Synthesis centers as critical research infrastructure
Demand for the opportunity to participate in a synthesis-center activity has increased in the years since the US National Science Foundation (NSF)–funded National Center for Ecological Analysis and Synthesis (NCEAS) opened its doors in 1995 and as more scientists across a diversity of scientific disciplines have become aware of what synthesis...

Anthropogenic sources of reactive nitrogen have local and global impacts on air and water quality and detrimental effects on human and ecosystem health. This paper uses the nitrogen footprint tool (NFT) to determine the amount of nitrogen (N) released as a result of institutional consumption. The sectors accounted for include food (consumption and...

The earth environment is a complex system, in which collaborative scientific approaches can provide major benefits by bringing together diverse perspectives, methods, and data, to achieve robust, synthetic understanding (Fig. 1). Face-to-face scientific meetings remain extremely valuable because of the opportunity to build deep mutual trust and...

The story of air pollution research, policy development, and management in national parks is a fascinating blend of cultural change, vision, interdisciplinary and interagency collaboration, and science-policy-management-stakeholder collaborations. Unable to ignore the loss of iconic vistas from regional haze and loss of fish from acid rain in the...
Baron, Jill S.; Blett, Tamara; Malm, William C.; Alexander, Ruth; Doremus, Holly Key ecological responses to nitrogen are altered by climate change
Climate change and anthropogenic nitrogen deposition are both important ecological threats. Evaluating their cumulative effects provides a more holistic view of ecosystem vulnerability to human activities, which would better inform policy decisions aimed to protect the sustainability of ecosystems. Our knowledge of the cumulative effects of these...

The differing biogeochemical and microbial signatures of glaciers and rock glaciers
Glaciers and rock glaciers supply water and bioavailable nutrients to headwater mountain lakes and streams across all regions of the American West. Here we present a comparative study of the metal, nutrient, and microbial characteristics of glacial and rock glacial influence on headwater ecosystems in three mountain ranges of the contiguous U.S.:...

Templer, Pamela H.; Lambert, Kathleen Fallon; Weiss, Marissa; Baron, Jill S.; Driscoll, Charles T.; Foster, David R. Long-term reactive nitrogen loading alters soil carbon and microbial community properties in a subalpine forest ecosystem
Elevated nitrogen (N) deposition due to increased fossil fuel combustion and agricultural practices has altered global carbon (C) cycling. Additions of reactive N to N-limited environments are typically accompanied by increases in plant biomass. Soil C dynamics, however, have shown a range of different responses to the addition of reactive N that...
Boot, Claudia M.; Hall, Ed K.; Denef, Karolien; Baron, Jill S. Optimizing available network resources to address questions in environmental biogeochemistry
An increasing number of network observatories have been established globally to collect long-term biogeochemical data at multiple spatial and temporal scales. Although many outstanding questions in biogeochemistry would benefit from network science, the ability of the earth- and environmental-sciences community to conduct synthesis studies within...

Synthetic nitrogen (N) fertilizer has enabled modern agriculture to greatly improve human nutrition during the twentieth century, but it has also created unintended human health and environmental pollution challenges for the twenty-first century. Averaged globally, about half of the fertilizer-N applied to farms is removed with the crops, while...
