2016 Workshop: Fire in Minnesota’s Forests

jack pine and charred cones 870pxEvent description: Many of Minnesota’s most productive forest systems are fire-dependent. At this day-long workshop, we’ll discuss the ecology and management of these systems, with a focus on the role of fire, including potential for increased use of prescribed burning. We’ll hear from a variety of speakers including applied researchers, forest managers, and fire managers from Minnesota and across the Lake States. The event will include hour-long panel discussions about the role of fire in managing jack pine, red pine, and oak-dominated systems.

Event summary: A diverse group of about 140 forest and wildlife managers, wildfire specialists, researchers, and others gathered in Grand Rapids to explore the state of fire in Minnesota’s forests. The event was designed to bring new energy to a discussion of Minnesota’s fire-dependent forests and the complex role of fire in maintaining healthy, productive forests.

To open the event, John Almendinger, an ecologist and leader in development of Minnesota’s Ecological Classification System, discussed the extent to which the fire regime shapes the distribution of Minnesota’s native plant communities. Interactions between fire rotation, typical fire severity, and fire extent drive the distributions of upland prairie, fire-dependent forest, and mesic hardwood forest systems in Minnesota. Finer-scale differences in these factors largely determine the distribution of plant communities within these systems.

Lee Frelich discussed ways that other disturbances mimic and differ from the effects of fire. Earthworm invasion, as an example, does “half the work of fires by removing the duff, but unlike fire does not kill red maple.” This is one factor leading to the “mesophication” of oak-dominated systems in Minnesota and across the region. Frelich also discussed how the relationship between fire and wind, and the changes in summer temperature, affect the trajectory of stand succession and compositional change. 

After the two opening talks, three approximately hour-long panels focused on fire in jack pine-, red pine-, and oak-dominated systems in Minnesota, and a fourth shared case studies of successful prescribed fire. These presentations included a mix of ecological and practical information related to historic fire, tree genetics, prescribed burn implementation and monitoring, lessons learned from decades of prescribed burning, and conventional wisdom about ecosystem function and silvicultural opportunities in these communities. The event ended with a panel composed of Brian Palik, Jack McGowan-Stinski, and Paul Dubuque synthesizing key themes throughout the day and looking to the future. 

There was a great deal of energy around this discussion and we look forward to working with the Lake States Fire Consortium and other partners to continue the discussion about how and when to most effectively incorporate fire in to Minnesota’s forests.
