Human augmentation of historical red pine fire regimes in the Boundary Waters Canoe Area Wilderness
Abstract The Border Lakes Region of Minnesota and Ontario has long been viewed as a fire‐dependent ecosystem. High‐severity fire in the region's near‐boreal forests has been a focus of ecological research and public fascination. However, the surface fire history within this transnational wilder...
