Whenever I visit a burned over area of eastern Washington range land I am impressed with the bioturbation as it shows up a bit better with the surface of the ground covered with blackened plant remains. Within days there are piles of freshly dug silts covering the landscape. A good reminder of how much soil turnover takes place in the upper soil horizon. These critters will do a very good job of disrupting carbon horizons and volcanic ash layers.
