Going slow to go fast: Landscape designs to achieve multiple benefits
Formally Refereed
Growing concerns about fire across the western United States, and commensurate emphasis on treating expansive areas over the next 2 decades, have created a need to develop tools for managers to assess management benefits and impacts across spatial scales. We modeled outcomes associated with two common forest management objectives: fire risk reduction (fire), and enhancing multiple resource benefits (ecosystem resilience).AuthorsPatricia N. Manley, Liraz Bistritz, Nicholas A. Povak, Michelle A. DaySourceFrontiers in Environmental Science. 13: 1560125.Year2025- Silvopasture is increasingly recognized as a nature-based solution to climate change. However, few studies have quantified the total carbon storage potential of silvopasture in humid continental climates, complicating efforts to understand climate mitigation potential. In this study, we compared the carbon stocks of silvopastures established by afforestation of trees into pastures (silvopasture) with pasture that remained without trees (treeless pasture) on five farms in the Northeastern United States. Total carbon content was measured in the woody, herbaceous, and soil pools for silvopastures...AuthorsJoseph Orefice, Matthew M. Smith, William C.

- Hardworking bees are a familiar sight outdoors as they forage for nectar and pollinate flowers. Along with nectar, both wild bees and honey bees collect pollen to bring back to brooding areas, where it feeds developing larvae. From the bee’s perspective, an important question arises: is all pollen nutritionally the same and, if not, how do bees get the nutrients they need?AuthorsSue Miller, Anthony Vaudo, Bryce Richardson, Sarah Barga, Justin RunyonKeywordsSourceScience You Can Use Bulletin, Issue 72.

A cellular necrosis process model for estimating conifer crown scorch
Formally Refereed
Fire-caused tree mortality has major impacts on forest ecosystems. One primary cause of post-fire tree mortality in non-resprouting species is crown scorch, the percentage of foliage in a crown that is killed by heat. Despite its importance, the heat required to kill foliage is not well-understood. We used the “lag” model to describe time- and temperature-dependent leaf cell necrosis as a method of predicting leaf scorch. The lag model includes two rate parameters that describe 1) the process of cells accumulating non-lethal damage, and 2) damage becoming lethal to the cell. To parameterize mo...AuthorsKate J. Fuller, Leda N. Kobziar, Rodman R. Linn, Sharon M. HoodKeywordsSourceEcological Modelling. 507: 111192.Year2025- 1. Human activities have significantly altered terrestrial ecosystems, leading to biodiversity loss and habitat fragmentation. Traditional methods for measuring human impacts often lack the precision required for localized assessments, fail to capture temporal dynamics or are scale-limited. Human mobility data (HMD) from GPS-enabled smartphone applications offers a valuable approach to understanding human movement patterns, overcoming many of these limitations. 2. We present case studies demonstrating the use of HMD in assessing human activity within ecologically sensitive habitats (e.g. winte...AuthorsHeather N. Abernathy, Mark A. Ditmer, Seth B.

- Global climate change phenomena are amplified in Arctic regions, driving rapid changes in the biota. Here, we examine changes in plant community structure over more than 30 years at two sites in arctic Alaska, USA, Imnavait Creek and Toolik Lake, to understand long-term trends in tundra response to changing climate. Vegetation cover was sampled every 4–7 years on permanent 1 m2 plots spanning a 1 km2 grid using a point-frame. The vascular plant canopies progressively closed at both locations. Canopy cover, defined here as an encounter of a vascular plant above the ground surface, increased fro...AuthorsKatlyn R. Betway‐May, William A. Gould, Sarah C. Elmendorf, Jeremy L. May, Robert D.

- In 2001, Lynch and Mackes published Wood Use in Colorado at the Turn of the Twenty-First Century (Lynch and Mackes 2001). Now more than twenty years later, this report updates wood use data and information to provide a current description and quantification of woody biomass utilization, consumption, and production in the state of Colorado. This assessment contributes to the ongoing discourse concerning sustainable solutions to the environmental challenges in Colorado forests, including uncharacteristic wildfires, increased mortality from insects, disease, and drought, and reduced productivity....AuthorsSrijana Baral, Kurt Mackes, Amanda West Fordham, Nathaniel Anderson, Maria GaetaniKeywordsSourceGen.

- Prescribed fires can be a significant source of air pollution with negative consequences for public health and safety. Therefore, smoke management is a key element in the planning and execution of prescribed fires. Emission factors (EF), which quantify the relative abundance of pollutants released by wildland fires, are a needed input for the emission calculations which are essential to effective smoke management. A key challenge when conducting prescribed fires near sensitive receptors such as roadways, communities, and outdoor recreational sites, is limiting smoke production from long-term s...AuthorsShawn P.
