Fires in croplands, plantations, and rangelands contribute significantly to fire emissions in the United States, yet are often overshadowed by wildland fires in efforts to develop inventories or estimate responses to climate change. Here we quantified decadal trends, interannual…

To trully allow fires to play their natural role in wilderness ecosystems, it is sometimes necessary to have large fires of long duration. Large fires are ecologically significant events that drive many other ecosystem processes. However, these fires pose significant management…
