    Description

    Fuel hazards have increased in forests across the United States because offire exclusion during the 20th century. Treatments used to reduce fuel buildup Illay affect wildlife. such as shrews. living 011 the forest floor. especially when treatments are applied repeatedly. From mid-May to mid-August 2006 and 2007.  we used drift fences with pitfall traps to capture shrews in western North Carolina in 3 fuel rcduction treatment areas {(1) twice-burned (2003 and 2006). (2) l1lechanicalunderstory cut (2002), and (3) mechanical understory cut(2002) followed by 2 burns (2003 and 2006)1 and a control. We captured 77% fewer southeastern shrews (Sorex lOllgirostris) in mechanical + twice-burned treatment areas than in mechanical treatment areas in 2006. but southeastern shrew capturcs did not differ among treatment areas in 2007. Total shrew captures did not differ among treatment areas in either year. Decreases in leaf litter, duff depth, and canopy cover in mechanical + twice-burned treatment areas may have decreased" ground-level moisture, thereby causing short-term declines in southeastern shrew captures. Prescribed fire or mechanical fuel reduction treatments in the southern Appalachian Mountains did not greatly affect shrew populations, though the combination of both treatments may negatively affect some shrew species. at least temporarily.
