AbstractField cage experiments conducted through the complete life cycle of Camnula pellucida (Scudder) demonstrated that wheat, the major cereal crop grown in Saskatchewan, played the dominant role in the nutritional ecology of this grasshopper. A native sod mixture, comprising Stipa comata, Bouteloua gracilis, Agropyron smithii, and Carex eleocharis, four of the dominant species of the mixed prairie association, was consistently unfavourable during all stages of grasshopper growth and development. Grasshoppers reared on wheat survived better, were considerably larger and laid up to 20 times more eggs than those reared on the native prairie grasses. The presence of the native sod with wheat contributed nothing nutritionally to the food combination. The unfavourable qualities of the native grasses, although resulting in small adults, low fecundity and small pods, did not affect the hatchability of eggs laid or the development and survival of nymphs that hatched from them.

Public interest in installing landscapes for reduced maintenance remains high. While availability and specification of native and/or adapted landscape plants such as wildflowers and prairie grasses increase, establishment, management, and expectations of such plantings are not well understood. Our objectives in this study were to measure temporal changes of mixed prairie wildflower plantings under various management regimes and to determine consumer expectations and preferences in these plantings. Nine combinations of wildflowers and prairie grasses were planted in June 1997 at the John Seaton Anderson Turfgrass and Ornamental Research Area, Univ. of Nebraska Agricultural Research Development Center near Mead. On-site surveys were conducted during the Festival of Color, a popular outreach event that occurs annually in September at the site. In 1997 and 1998, the festival attracted more than 9000 and 10,500 participants, respectively, of which 750 completed the survey. To determine preferences for planting compositions, plot desirability ratios were calculated from scaled responses. In 1997, respondents preferred the planting composed of only annuals by a ratio of 5.8: 1 (rated desirable vs. undesirable). This result changed dramatically by the second year, in which the desirability ratio for annuals was 0.3: 1, while that of the combination of perennials and annuals was 11.2: 1. Our plant population density and flowering data validate consumers' preference for abundant color. In late summer of the establishment year (1997), the percentage of the plant population in full bloom was highest in the planting of annuals alone as expected and in 1998 was lowest in the annuals.

Samples of individual species of forages from two locations, one with a high and one with a low incidence of urolithiasis, were collected intermittently during an 8-year period and analyzed for protein, sand, and silica at up to five stages of growth. The grasses and sedges from both locations were higher in silica than the forbs and shrubs but the difference between locations was not significant. The effect of other factors on urolithiasis is discussed, such as the forb–shrub to grass–sedge ratio, the proportion of each consumed by cattle, the availability of water, and the amount of water actually consumed by cattle in the two areas.

A goal of this study is to establish temporal evaluations of the problems homeowners may encounter when establishing mixed prairie wildflower plantings. These plantings are often attempted with the notion that the composition of the planting will remain static over time with little or no maintenance. Six combinations of wildflowers and prairie grasses were compared for consumer preference. A survey was conducted at the long-term forbs research plots during the Festival of Color, an open house event at the John Seaton Anderson Turfgrass and Ornamental Research Area, Univ. of Nebraska Agricultural Research Development Center near Mead, Neb. Of the 9000 participants in the festival, ≈850 visited the plots. Of those, nearly 300 completed the survey instrument. Results from the first year indicate that the majority of respondents were homeowners who do their own yard work. Most of them considered a low maintenance landscape to be an important way in which to conserve resources such as water and fertilizer and reduce pesticide use. Most had grown prairie wildflowers and considered them to be low maintenance. The study showed that, depending on the planting composition, it would require between 59 and 118 h of weeding to establish wildflowers in the majority of respondents' home landscapes, which were between 1717 m2 and 1525 m2. The majority (56%) of visitors preferred combinations that included annuals but excluded prairie grasses. The majority (66%) disliked the combinations of prairie grasses without the inclusion of wildflowers.
