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.

Pitch pine common garden plots in the Brendan T. Byrne State Forest, New Jersey, were planted in 1973 and 1974. The experiments include progeny of hundreds of trees raised from seeds collected in 72 different stands or “seed sources” throughout the natural distribution of pitch pine, ranging from Georgia to Quebec and from the coast of Maine to Ohio. John Hom, U.S. Department of Agriculture Forest Service.

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.
