Résumé
A survey of three university classes found that students preferred turfgrass to grass/wildflower landscapes, but liked grass/wildflower landscapes better in mountain settings. An experimental study examined irrigation and mowing effects on species diversity of four grass/wildflower mixtures. Unmowed/unirrigated conditions maintained highest diversity, while mowed/irrigated conditions maintained least diversity. Mowed plots contained more Achillea millifolium and Trifolium fragiferum and less Aster chilensis . Irrigated plots contained more wildflowers. Unmowed/irrigated plots were taller than unmowed/unirrigated plots. A. chilensis was least competitive, A. millifolium most competitive, and T. fragiferum was slightly less competitive than A. millifolium . An observational study found that Artemesia ludoviciana and Poa compressa were very aggressive, and Campanula rotundifolia and Poa sp . (P. compressa excluded) were not very aggressive.
