Avian Use of a Lakeshore Buffer Strip and an Undisturbed Lakeshore in Maine
Abstract:We examined avian use of a lakeshore buffer strip and an undisturbed lakeshore in eastern Maine during 1984-85. Breeding bird density and species richness were lower in the buffer strip than in the undisturbed lakeshore. Of 35 species that nested in both study areas, 11 species nested only in the undisturbed lakeshore and 3 nested only in the buffer strip. A harvest index (HI) was developed to compare avian response to timber harvest within the buffer strip. Birds associated with forest interiors were observed less frequently on sites with a high HI than on sites with a low HI (e.g., blackburnian warbler, ovenbird, northern parula warbler). Species often found in cutover areas or edges were frequently counted on sites with a high HI. Eight species were found most frequently in lightly cut areas (i.e., low HI), 4 most frequently in moderate cuts, and 9 in greater HI. Although more species of birds were observed each year in the undisturbed lakeshore, the buffer strip provided breeding habitat for songbirds. For both years, 59% of all recorded breeding bird species were observed at both the undisturbed lakeshore and the buffer strip. North. J. Appl. For. 7:114-117, September 1990.
