National Research Highlights
Understanding Wind Gusts During Fire can Help Fire and Smoke Managers
Year: 2018
Wind fields in the vicinity of wildland fires can be highly variable or turbulent, exhibiting significant gusts that can lead to erratic fire behavior and enhanced mixing of smoke into the atmosphere. Northern Research Station scientists are examining the properties of turbulent circulations in forested wildland fire environments to ultimately improve predictive tools for fire and smoke management.
Long-term Provenance Trials for Selection of Future Forests
Year: 2016
Long-term experiments initiated in 1973 and revisited in 2010 provide insights into pitch pine response to climate change and disturbance.
