Contour Strips For Prairie Invasion On A Topsoil-Depleted Hilltop At Retzer Nature Center, J. A. Schwarzmeier
Contour Strips For Prairie Invasion On A Topsoil-Depleted Hilltop At Retzer Nature Center, J. A. Schwarzmeier
Proceedings of the North American Prairie Conferences
In 1981, 20% of a 3.3-acre (1.3-ha) portion of an eroded Hochheim loam on the Retzer "Vista" hilltop, in southeastern Wisconsin, was planted in 12-ft (3.7-m) wide "source strips" so that intervening 48-ft (15-m) wide "invasion strips" resulted. A dry-mesic prairie seed mix was used in the two highest elevation source strips and a mesic prairie seed mix was used in three source strips on the lower, side-sloped portion of the hilltop. While the fanning-era loss of essentially all of the original topsoil made the site "drier," the associated bringing up of more and more of the subsoil, with time, …

Soil Chemistry Properties Under Two Different Management Practices: Clipped Saint Augustine Grass Lawn And Annually Burned Cajun Prairie, Domingo M. Jariel, Malcolm F. Vidrine, Nicole Bordelon, Janeel Al-Dujaili

Prescribed burning every two or more years is the recommended management practice to remove unnecessary invasive plants and to enhance the regrowth of desirable plants for the development of a fire-dependent plant community native to southwestern Louisiana. A portion of Saint Augustine grass lawn at Louisiana State University at Eunice (LSUE) was converted into a Cajun Prairie restoration plot in 1989. Since 1991, the adjacent lawn has been clipped weekly, whereas the prairie has been burned every January. The objective of this study was to determine the soil chemical properties of clipped lawn and burned prairie plots. Each plot (12 …
Growth And Reproduction Of Local Ecotype And Cultivated Varieties Of Panicum Virgatum And Coreopsis Palmata Grown In Common Gardens, D. W. Williams, G. A. Houseal, D. D. Smith
Growth And Reproduction Of Local Ecotype And Cultivated Varieties Of Panicum Virgatum And Coreopsis Palmata Grown In Common Gardens, D. W. Williams, G. A. Houseal, D. D. Smith

Many practitioners prefer to plant seed from multiple remnant sources within the same region of the planting site. It is believed that this seed has improved fitness (survivorship, growth, and viability) over seed from outside the region. We tested this assumption by establishing two common gardens in northern and southern Iowa. Four varieties of switchgrass (Panicum virgatum) from prairie remnants in northern and southern Iowa and two cultivated varieties from Nebraska and South Dakota}, and stiff tickseed (Coreopsis palmata) from prairie remnants in northern and southern Iowa, were established in a greenhouse and transplanted into each …
