Fig. 1. Botanical composition of three forage mixtures under grazing or haying management in southeastern Pennsylvania. The mixtures were two species (orchardgrass and white clover), three species (orchardgrass, alfalfa, and chicory), and 11 species (alfalfa, orchardgrass, chicory, white clover, meadow bromegrass, smooth bromegrass, birdsfoot trefoil, Matua bromegrass, tall fescue, reed canarygrass, and timothy). White clover, reed canarygrass, timothy, and birdsfoot trefoil did not establish in the complex mixture. Grazing exclosures were installed in May 1999. Data are averages of two replicate pastures for each sampling date. Error bars within each management treatment represent pooled year x mixture x species standard errors.
