Small Mammal Communities In Grasslands At The Grand Forks Air Force Base, North Dakota, Usa, Lynda R. Lafond, Elizabeth H. Rave, Kathryn A. Yurkonis
The Prairie Naturalist
Small mammals are important in grasslands but are often overlooked in management and reconstruction efforts. We sampled small mammals in three sites on the Grand Forks Air Force Base (GFAFB) located in central Grand Forks County, North Dakota, USA. The study sites varied in their management history and represented the three major types of grasslands (reconstructed prairie, old field, and hay field) within Grand Forks County. We captured 463 individuals of six species with Sherman live traps in summer (June, July, August) 2014 and 2015. We captured the most individuals and species (295 individuals of 5 species), including all shrews …
Project Prairie And Tallgrass Education On The Rice Lake Plains: A Journey From 1870 To Today And Beyond, Todd Farrell, Mark Rupke, Mark Stabb
Project Prairie And Tallgrass Education On The Rice Lake Plains: A Journey From 1870 To Today And Beyond, Todd Farrell, Mark Rupke, Mark Stabb
The Prairie Naturalist
Project Prairie began in 2011 as a curriculum-linked integrated environmental studies program to showcase the Rice Lake Plains (RLP), a tallgrass prairie landscape of sandy rolling hills located at the eastern extent of the Oak Ridges Moraine in southern Ontario. Project Prairie provides educators both indoor and outdoor activities that support their curriculum and share the story of the RLP. Project Prairie provides teacher and student resources that focus on the RLP from the mid-nineteenth century to present day. Learning objectives of Project Prairie are developed from the subjects of science, social science, language arts, geography, history, and Aboriginal culture. …
Prairie Restoration: Bridging The Past And The Future, Daryl D. Smith
Prairie Restoration: Bridging The Past And The Future, Daryl D. Smith
The Prairie Naturalist
Tallgrass prairie once dominated most of mid-continent North America. Conversion of this prairie to cropland was rapid and extensive. Today, it is the most decimated ecosystem in North America with less than two percent remaining. Prairie reconstruction began at the University of Wisconsin Arboretum in the 1930s. Thirty years later, exemplary initiatives by a group of highly motivated restorationists in Illinois and Iowa became a part of the legacy of restoration ecology. Their work generated widespread public interest in prairie restoration and initiated the ongoing biennial North American Prairie Conference. Since then, practitioners have made significant advances in reconstruction and …
Spatiotemporal Variation In Vegetation Structure Resulting From Pyric-Herbivory, Sherry Leis, Lloyd W. Morrison, Michael D. Debacker
Spatiotemporal Variation In Vegetation Structure Resulting From Pyric-Herbivory, Sherry Leis, Lloyd W. Morrison, Michael D. Debacker
The Prairie Naturalist
Pyric-herbivory is a process that is widely assumed to create greater habitat heterogeneity in grasslands at the landscape scale than could be achieved by either fire or grazing alone. Yet, few studies have actually quantified the effects of pyric- herbivory on vegetation structure within layers of the grass canopy. Here we quantify the effects of pyric-herbivory on a pasture at Tallgrass Prairie National Preserve in Kansas. We subdivided the pasture into three patches and burned one patch each year in a three-year rotation. We estimated visual obstruction for 25-cm strata and recorded maximum vegetation height. We found that recently burned …
Cattle Grazing Reduces Survival And Reproduction Of The Western Prairie Fringed Orchid, Bonnie Warner Alexander, Donald Kirby, Mario Biondini, Edward Dekeyser
Cattle Grazing Reduces Survival And Reproduction Of The Western Prairie Fringed Orchid, Bonnie Warner Alexander, Donald Kirby, Mario Biondini, Edward Dekeyser
The Prairie Naturalist
QuantifYing impacts of livestock grazing and prairie management strategies on the threatened western prairie' fringed orchid (Platanthera praeclara) is difficult due to the erratic appearance of the orchid above-ground. We monitored above-ground survival of orchids from flowering to mature seed capsule production, comparing plant height, flower numbers, and seed capsule numbers from 2002-2004 in rotationally grazed pastures and non-grazed sites. Orchid survival differed significantly between grazed and non-grazed pastures, with the proportion of plants surviving from flower to capsule production consistently lower in grazed pastures. Mean orchid survival in grazed and non-grazed areas was 40% and 87%, respectively. …
Patterns Of Bison Hair Use In Nests Of Tallgrass Prairie Birds, Bryan R. Coppedge
Patterns Of Bison Hair Use In Nests Of Tallgrass Prairie Birds, Bryan R. Coppedge
The Prairie Naturalist
I examined patterns of bison (Bison bison L.) hair use by passerine birds nesting in the Tallgrass Prairie Preserve, Osage County, Oklahoma, 2002-2004. I collected and dissected 103 nests of 15 species into their constituent components. Nests were predominately composed of herbaceous material such as grass stems and leaves. Woody material and mud were rarely used. Bison hair was the most prominent zoological material used in nests, with lesser amounts and occurrence of arthropod silk, snake skin, feathers, jack rabbit (Lepus californicus Oray) fur, and man-made materials such as cellophane and string. At least one nest of 13 …
