Most ecosystems in North America evolved with the aid of periodic fires. Managers of natural areas, including prairies and wetlands, who seek to maintain ecologically diverse sites will at some point explore the use of fire in their management program. This article introduces…

We develop a simple analytical model to estimate the thickness of a smoke layer formed by a plume of a large area fire and to account for crosswinds. We take advantage of the dominant flow features in the upper part of the rising plume and in the smoke layer far from the plume…
