Number of birds per individual species/100 ha/day, number of bird species of all species combined/100 ha/day, and total number of species observed per treatment unit on the Green Lane Research and Demonstration Area in spring and summer, 2001 and 2002 combined. Treatment units: M = mowing, F = foliage spray, MH = mowing plus herbicide, SF = stem–foliage spray, and HC = handcutting.
