Multi-Scale Habitat Use Of Male Ruffed Grouse In The Black Hills National Forest, Cassandra L. Mehls, Kent C. Jensen, Mark A. Rumble, Michael C. Wimberly
Multi-Scale Habitat Use Of Male Ruffed Grouse In The Black Hills National Forest, Cassandra L. Mehls, Kent C. Jensen, Mark A. Rumble, Michael C. Wimberly
The Prairie Naturalist
Ruffed grouse (Bonasa umbellus) are native upland game birds and a management indicator species (MIS) for aspen (Populus tremuloides) in the Black Hills National Forest (Black Hills). Our objective was to assess resource selection of male ruffed grouse to identify the most appropriate scale to manage for aspen and ruffed grouse in the Black Hills. During spring 2007 and 2008, we conducted drumming surveys throughout the central and northern Black Hills to locate used and unused sites from which we compared habitat characteristics at increasing spatial scales. Aspen with >70% overstory canopy cover (OCC) was important to the occurrence of …
Quantifying Differences In Habitat Use Between Anglers And Large Bluegills, Eric J. Weimer, Michael L. Brown, Brian G. Blackwell
Quantifying Differences In Habitat Use Between Anglers And Large Bluegills, Eric J. Weimer, Michael L. Brown, Brian G. Blackwell
The Prairie Naturalist
We compared the habitat use of large (>200 mm) bluegills (Lepomis macrochirus) to the locations of anglers targeting bluegills in a South Dakota glacial lake to determine whether habitat use was similar between anglers and bluegills. Eighty- five bluegills (mean total length = 213 mm) collected in September 2002 and May 2003 were affixed with external radio transmitters and subsequently relocated three to four times per week from October 2002 through October 2003. Bluegill angler locations were recorded during bluegill tracking sessions and roving creel surveys. Habitat variables (water depth, vegetation density and height, and substrate type) were measured …
Avian Diversity And Habitat Use On Wetland Reserve Program Lands In The Lower Missouri River Valley, Eric C. Hopps
Avian Diversity And Habitat Use On Wetland Reserve Program Lands In The Lower Missouri River Valley, Eric C. Hopps
The Prairie Naturalist
A primary objective of the Wetland Reserve Program (WRP) is to provide habitat for migratory birds throughout all seasons of the year. Comprehensive avian assessments are lacking and limit our ability to evaluate the benefits of the WRP to continental bird populations. I investigated avian species occurrence on WRP lands within the Lower Missouri River Valley (LMRV), Nebraska, USA, from March 2010 to February 2011. Ten WRP habitat types are described based on plant community assemblages and observed hydrological regimes. Estimates of avian species richness were greatest in lowland forest (n = 115), lowland woodland (n = 83) and upland …
Factors Associated With Duck Use Of Impounded And Natural Wetlands In Western South Dakota, Jane E. Austin, Deborah A. Buhl
Factors Associated With Duck Use Of Impounded And Natural Wetlands In Western South Dakota, Jane E. Austin, Deborah A. Buhl
The Prairie Naturalist
Many wetlands in the northern Great Plains west of the Missouri River are stock ponds, created by impoundment of natural drainages or excavation of existing wetlands to provide water for livestock or improve habitat for waterfowl. We evaluated factors influencing use of wetlands by breeding duck pairs and broods relative to modification, water regime, size, and hydrological location on United States Forest Service lands within the Grand River National Grassland in northern South Dakota (2003 and 2004). Responses for both indicated pairs and broods were related positively to wet area, total wetland area within 4 km, emergent edge cover, and …
Woodland Bird Use Of In-Channel Islands In The Central Platte River, Nebraska, William C. Scharf
Woodland Bird Use Of In-Channel Islands In The Central Platte River, Nebraska, William C. Scharf
The Prairie Naturalist
Recapture data showed woodland obligate birds from riparian habitats made substantial use of thinly vegetated, adjacent small islands in the Platte River. During the bird nesting and spring migration seasons of 200 I through 2004, there were 4,360 individuals of 90 species captured on both mainland and in: hannel island sites. Island locafion captures totaled 595 individuals of 47 species )etween 2002 and 2004. Islands formerly were considered inconsequential for coraging and nesting of passerines. My study substantiated passerine use of Islands and provided a rationale for additional consideration of islands for migration and nesting management. Assemblages of bird species …
