Abstract: ["Two prominent gradients in community composition were found. One ordination axis corresponded with air-quality gradient relating to ammonia deposition. The second axis was correlated with humidity (r = –0.78), distance from the coast (r = 0.62), kriged estimates of cumulative ozone exposure (r = 0.57), maximum one-hour measurements of ozone (r = 0.58), and annual means of nitrogen dioxide (r = 0.63)."
