Decaying wood on the forest floor retains large reservoirs of moisture and thus provides long-lasting, high-moisture microsites that aid in forest recovery after prolonged drought or fire. Examination of longs after the Galice Complex fires in southwest Oregon revealed considerable root and mycorrhizal actiivity. Mean log moisture (157%) was 25 times greater than mean soil moisture (6%). After extended drought and wildfire, the moisture stored in logs may expedite forest recovery by providing important refuges for roots and associated mycorrhizal fungi of pioneering vegetation.
