Predator Exclosures, Predator Removal, And Habitat Improvement Increase Nest Success Of Snowy Plovers In Oregon, Usa, Stephen J. Dinsmore, David J. Lauten, Kathleen A. Castelein, Eleanor P. Gaines, Mark A. Stern

Natural Resource Ecology and Management Publications

Management to increase reproductive success is commonly used to aid recovery of threatened and endangered species. The Western Snowy Plover (Charadrius nivosus nivosus) breeds from coastal Washington, USA, to Baja California, Mexico, and in disjunct interior sites. The Pacific coast population is federally listed as Threatened; habitat loss and nest loss to a suite of terrestrial and avian predators are thought to be primary factors limiting population growth in this species. In coastal Oregon, USA, a consortium of state and federal management agencies deployed nest exclosures on active Snowy Plover nests, initiated a lethal predator management program, and conducted local-scale ...


Quality Over Quantity: Buffer Strips Can Be Improved With Select Native Plant Species, Kelly Ann Gill, R. Cox, Matthew E. O'Neal Apr 2014

Quality Over Quantity: Buffer Strips Can Be Improved With Select Native Plant Species, Kelly Ann Gill, R. Cox, Matthew E. O'Neal

Entomology Publications

Native plants attractive to beneficial insects may improve the value of buffer strips by increasing biodiversity and enhancing the delivery of insect-derived ecosystem services. In a 2-yr field experiment, we measured the response of insect communities across nine buffers that varied in plant diversity. We constructed buffers with plants commonly found in buffers of USDA-certified organic farms in Iowa (typically a single species), recommended for prairie reconstruction, or recommended for attracting beneficial insects. We hypothesized that the diversity and abundance of beneficial insects will be 1) greatest in buffers composed of diverse plant communities with continuous availability of floral resources ...


Patch Burn‐Grazing: An Annotated Bibliography, Rajeeva Voleti, Stephen L. Winter, Sherry Leis Jan 2014

Patch Burn‐Grazing: An Annotated Bibliography, Rajeeva Voleti, Stephen L. Winter, Sherry Leis

Papers in Natural Resources

Patch burn‐grazing is a rangeland management strategy that exploits the attraction of grazing animals to recently burned areas in order to achieve management objectives. When fiire is applied to a landscape in a patchy manner, leaving some patches unburned, the resulting grazing animal activity, forage utilization, and animal impact are patchily distributed within that landscape as well. Areas that have been recently burned tend to be characterized by the highest levels of grazing animal activity while areas that have gone the longest without burning tend to be characterized by the lowest levels of grazing animal activity. This can be ...
