LINCOLN, Neb. (RFD-TV) — The Great Plains grasslands are shrinking as invasive trees continue to threaten ecosystems that sustain agriculture across the region. Researchers at the University of Nebraska–Lincoln are working to address the growing problem of woody encroachment.

Dr. Dirac Twidwell with the Department of Agronomy and Horticulture says the issue has become increasingly urgent for Nebraska as native grasslands disappear, impacting both wildlife and working lands. His team has developed strategies to help landowners push back — including data-driven tools and management practices designed to identify and stop tree expansion before it spreads.

Twidwell also highlighted ongoing collaboration with the Natural Resources Conservation Service (NRCS), where these tools are being applied to help producers manage land more effectively. As efforts expand, researchers are focused on scaling up prevention and restoration efforts to protect what remains of the Great Plains grasslands.
