Title: Changes in incident light intensity to streams with progressive hemlock mortality at 5 Coweeta Hydrologic Laboratory study sites from 2005 to 2015
Abstract: The purpose of this study was to document changes in light intensity to streams in areas affected by hemlock mortaity. From June 2005 to November 2015, relative light intensity at 5 locations along each stream reach was monitored every 5 minutes. This study was conducted at Coweeta Hydrologic Laboratory. Five stream sites were located on 1st - 2nd order streams reaches affected by hemlock death. All sites were located in areas that have not been logged since the area became National Forest in the late 1920s and where streams passed through or were adjacent to permanent vegetation plots in which trees were measured in 1934-35, 1969-73 and 1988-93 (Elliott and Swank, 2008.)
