Variability and persistence of post-fire biological legacies in Michigan jack pine forests
Dan Kashian (Wayne State University)

On the dry, flat, jack pine-dominated ecosystems of the northern Lake States and eastern Canada, wildfire behavior often produces narrow, remnant strips of unburned trees that provide heterogeneity on a landscape historically shaped by stand-replacing wildfires. The major objective of this research was to describe the natural range of variability of stringer patterns and their persistence and change during the fire-free interval. The historical persistence and importance of these features also highlights their importance on modern fire-prone landscapes, particularly in northern Lower Michigan where a high proportion of land management is focused on jack pine plantations for breeding habitat for Kirtland's warbler, an endangered species.
