This book was released on 1985 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of season-long grazing, short duration and twice-over deferred rotation grazing systems, and idle non-use areas on upland nesting birds were evaluated from the results of nesting studies,breeding bird surveys, and visual obstruction readings of vegetative cover. Higher nesting densities of upland nesting birds were found in the undisturbed vegetation of idled areas, the ungrazed areas of season-long grazing treatments, and on the pastures or cells of grazing systems where grazing was deferred until later in the nesting season.This strong relationship between higher nest densities and undisturbed cover was clearly related to the presence of nesting cover, residual or new growth, of sufficient height and density to attract nesting hens.Dense nesting cover with low levels of disturbance were safer nest sites. Findings suggest that well-managed grazing practices and grazing systems, employing pasture deferments, may be beneficial to upland nesting birds if implemented on a.

Book excerpt: The effects of seasonlong grazing, short duration, twice-over rotation,and complementary grazing systems, and idle grassland on upland nesting ducks were determined from the results of waterfowl nesting studies,waterfowl pair counts, and visual obstruction readings taken in the vegetation. The visual obstruction readings and available nesting cover were higher (P

Download or read book Effects of Grazing Systems on Upland Nesting Birds in South Central North Dakota written by Kevin K. Sedivec and published by . This book was released on 1989 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effects of seasonlong grazing, complementary, short-duration,switchback, and twice-over rotation grazing treatments, and non- grazed prairie on upland nesting ducks were evaluated from nesting studies on the Central Grasslands Research Station. Undisturbed cover contained the highest densities of duck nests on the Station. Undisturbed cover consisted of grazing treatments before the initiation of the grazing season, which contained the highest percentage of total duck nests at 58.8%, followed by deferred areas on rotation grazing treatment (16.7%),and an idle area (13.5%). Only 11% of ducks nested on grazed plots.Nesting success in 1987 and 1988 was highest on twice-over rotation grazing system with 49.3 and 34.0 percent, respectively. Nesting success in 1987 and 1988 on an idle area was 16.3 and 7.0 percent, respectively.Ducklings produced was highest on switchback grazing system with 124.3 per 40.5 ha in 1987 and highest on twice-over rotation grazing system with 74.1 per 40.5 h.

This book was released on 2005 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the central US, land use change has resulted in the loss and fragmentation of grassland habitats. We examined the influence of different restoration practices (burning and grazing, both separately and in combination) on native plants and grassland birds within the Loess Hills, Iowa at Broken Kettle Grasslands (BKG) Preserve in 2003-04. Vegetation characteristics varied significantly with treatment. Burned-only plots had more native plant species and a higher percentage of bare ground compared to other treatments, while grazed plots tended to have fewer shrubs, higher litter depth, and greater litter cover. Bird response to habitat restoration varied with treatment and species life history traits. Obligate grassland species, such as Grasshopper Sparrows (Ammodramus savannarum) and Western Meadowlarks (Sturnella neglecta), were consistently less abundant in burned-only treatments. In contrast, Dickcissels (Spiza americana), showed no difference among treatments, and woodland edge species, such as Lark Sparrows (Chondestes grammacus), were more abundant in these areas. Grasshopper Sparrows selected nest sites with short vegetation and a shallow litter layer, whereas Dickcissels selected nesting habitat closer to and with a higher percentage of tall shrubs. Patterns in nest success and seasonal productivity were opposite those shown in relative abundance. Grasshopper Sparrows preferred to nest in habitat that had been grazed, yet nest success and seasonal productivity were highest in burned-only treatments. These results suggest that grazing may have a negative effect on grassland bird populations at BKG. Consequently, we recommend a restoration approach that includes both burning and grazing, considering timing and distribution of grazing regimes, for sustaining populations of threatened grassland bird species with varying habitat preferences.
