Autor: Mark West, Corie B. Ereth, Kevin K. Sedivec, E. Shawn DeKeyser, John R. Hendrickson, Donald R. Kirby

Publikováno v: Invasive Plant Science and Management. 10:80-89

Kentucky bluegrass (Poa pratensis L.) invades northern Great Plains rangelands. On the Sheyenne National Grassland in southeastern North Dakota, three research sites, each with a different level of Kentucky bluegrass invasion, were chosen to evaluate

Evaluation of Restored and Native Prairie Pothole Region Plant Communities Following an Environmental Gradient

Autor: Breanna L. Paradeis, Edward S. DeKeyser, Donald R. Kirby

Publikováno v: Natural Areas Journal. 30:294-304

Historically, wetland and grassland ecosystems throughout the Prairie Pothole Region (PPR) of North America were shaped by fire, grazing, and alternating drought and deluge conditions. These historic disturbance patterns of the PPR have been altered

Breeding Bird Selection of Restored and Native Wooded Draws in North Dakota

Autor: Donald R. Kirby, David J. Nilson, Kelly D. Krabbenhoft

Publikováno v: Rangelands. 31:9-15

Breeding birds have affinities for specific habitats. North Dakota provides numerous unique landscapes for breeding birds, but in western North Dakota, wooded draws are a major habitat. In total landscape, however, wooded draws comprise only 6– 8%

Leafy Spurge Suppression by Flea Beetles in The Little Missouri Drainage Basin, USA

Autor: Gerald L. Anderson, Donald R. Kirby, Jack E. Norland, Luke W. Samuel

Publikováno v: Rangeland Ecology & Management. 61:437-443

The Ecological Area-wide Management Leafy Spurge, or TEAM Leafy Spurge, began collecting and redistributing flea beetles (Aphthona spp.) to research/demonstration sites and landowners throughout the Little Missouri River drainage basin to control lea

Integrated Leafy Spurge (Euphorbia esula) Control Using Imazapic, Aphthona spp. Biological Control Agents, and Seeded Native Grasses

Autor: Chelsea J. Juricek, Donald R. Kirby, Dwight A. Tober, Laurie A. Richardson, Rodney G. Lym

Publikováno v: Invasive Plant Science and Management. 1:255-264

Chemical, cultural, and biological methods have been developed to control leafy spurge in a variety of environments. Aphthona spp. biological control agents have established throughout the northern Great Plains and Rocky Mountain region and successfu

Regional assessment of wetland plant communities using the index of plant community integrity

Autor: Edward S. DeKeyser, Michael J. Ell, Donald R. Kirby, Christina L. M. Hargiss

Publikováno v: Ecological Indicators. 8:303-307

The Index of Plant Community Integrity (IPCI) was developed to assess wetland plant communities in the Prairie Pothole Region. The IPCI evaluates the condition of wetland plant communities based on disturbance level and multiple community attributes.

Leafy Spurge (Euphorbia esula) Control with Aphthona spp. Affects Seedbank Composition and Native Grass Reestablishment

Autor: Dean Cline, Donald R. Kirby, Chelsea J. Juricek, Rodney G. Lym

Publikováno v: Invasive Plant Science and Management. 1:120-132

Aphthona spp. flea beetles have established and reduced the density of leafy spurge in much of the western United States. One way to measure the long-term impact and effectiveness of a weed control program is by monitoring the changes in the seedbank

An index of plant community integrity: development of the methodology for assessing prairie wetland plant communities

Autor: Donald R. Kirby, Michael J. Ell, Edward S. DeKeyser

Publikováno v: Ecological Indicators. 3:119-133

We developed an Index of Plant Community Integrity (IPCI) for quantitatively assessing the quality of seasonal wetland plant communities. In 1998 and 1999, we sampled the plant communities of 46 seasonal wetlands in the Prairie Pothole Region (PPR) o
