Stephanie Yelenik is a Rangeland Scientist with the Rocky Mountain Research Station, US Forest Service, in Reno, NV. She is interested in plant-ecosystem interactions and how these alter the trajectory of plant communities that are under diverse anthropogenic threats, including invasive species, increased wildfire regimes, and climate change. She combines ecological theory with empirical, field-based experiments to address problems that have application to management and restoration.

The forestlands of the Southeast United States are some of them most productive in the world. However, there are several major threats that reduce productivity and economic return each year. Threats from extreme weather, invasive species, wildfire, and diseases have increased in severity due to climate change. Fortunately, there are adaptation practices that landowners can use to reduce or eliminate these threats, while increasing stand value.

2023 Annual Accomplishments of the Northern Forests Climate Hub
The USDA Northern Forests Climate Hub has worked hard throughout Fiscal Year 2023 to provide more outreach and training opportunities to new and familiar audiences, to identify new collaborative opportunities that bring partners together, and to co-produce several products.

When planting trees after a wildland fire or timber harvest (reforestation) or on land that did not previously have trees (afforestation), it is important to plant the right seed or seedling in the right place. The right seed or seedling will become a tree that is suited to survive, grow, and reproduce in the current and future climate. The Seedlot Selection Tool helps foresters, landowners, and land managers to consider climate change when planning reforestation and afforestation projects.

Rangeland scientists at the Eastern Oregon Agricultural Research Center (EOARC) tested whether virtual fencing could prevent cattle from grazing recently burned areas within sagebrush steppe pastures. Because changes in climate are expected to increase fire frequency in sagebrush steppe, ranchers and rangeland managers will need new, cost-effective methods of separating cattle from burned areas on public rangelands. Virtual fencing presents a compelling climate change adaptation option.

Coastal forests and farmlands in parts of the Southeast are being negatively affected by saltwater intrusion and salinization. Elevated salinity levels cause crop yield declines, coastal forest loss, salt-tolerant invasive species takeover, eutrophication and marsh migration.

How do forests respond to climate change? Or air pollution? Or whole tree harvests?
At the Hubbard Brook Experimental Forest (HBEF) in New Hampshire, scientists are finding out. Hubbard Brook is the USDA Forest Service site that first discovered acid rain in the U.S. Researchers there have been carrying out experiments across forest plots and even whole watersheds for over 65 years.
