Title: Beavers are partners in riparian restoration on the Zuni Indian Reservation: Journal: Ecological Restoration; Authors: S. Albert, and T. Trimble; Date: 2000; Summary: This short project report highlights the efforts of the Zuni Fish and Wildlife Department in developing and implementing a comprehensive program of wetland and riparian restoration. An important and innovative component of this program is the use of beaver (Castor canadensis) to restore riparian habitat. The ecological effect of the decline in beaver populations from late 18th century through the early 20th centuries and the reintroduction in 1985-1999 is highlighted. ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Cattle herbage utilization patterns under high-density rotational grazing in the Aspen Parkland: Journal: Canadian Journal of Animal Science; Authors: S. A. Asamoah, E. W. Bork, B. D. Irving, M. A. Price, and R. J. Hudson; Date: 2003; Summary: The use of riparian meadows, upland grasslands, and forests by cattle grazed in a twice grazed high-density rotational grazing system (early season-stocking rate = 1.1 AUM/ha for 4 days, late season-stocking rate = 0.9 AUM/ha for 3 days) was examined in this study at the Alberta Kinsella Research Station (53ï¿½ 01ï¿½ N; 111ï¿½ 34ï¿½ W). Within the Aspen Parkland ecoregion and with the wagon wheel grazing system use was hypothesized that use would be similar among the three habitat types.

Title: Impact of cattle grazing on prostigmatid mite densities in grassland soils of southern interior British Columbia: Journal: Canadian Journal of Soil Science; Authors: J. P. Battigelli, G. S. McIntyre, K. Broersma, and M. Krzic; Date: 2003; Summary: Effects of cattle grazing on the soil mesofauna community of southern interior British Columbiaâ€™s grasslands (50Â° 45â€™ N, 120Â° 25â€™ W) were examined for one year. An existing grazing experiment with 2 grazing treatments (not grazed and grazed in both spring and fall) was used. Five soil cores at two depths (0 to 4 cm and 4 to 8 cm) were collected per sampling unit in late-August and early-October. Faunal samples were sorted, counted and identified. ...; Agrovoc Control Words: Rangelands, Grazing, Wildlife; View more details about this article

Title: Assessing the impact of goose grazing on vegetation in the Arctic: Journal: IBIS-The International Journal of Avian Science; Authors: D. R. Bazely; Date: 1988; Summary: This scientific opinion paper focuses on the weaknesses of recent studies out at La Perouse Bay on the coast of Hudson Bay that have examined the effect of Lesser Snow Geese grazing on net above-ground primary production (NAPP). ...; Agrovoc Control Words: Grazing, Tundra, Wildlife; View more details about this article

Title: Changes in the composition and standing crop of salt-marsh communities in response to the removal of a grazer: Journal: Journal of Ecology; Authors: D. R. Bazely, and R. L. Jefferies; Date: 1986; Summary: The effects of excluding grazing by lesser snow geese (Anser caerulescens caerulescens) on the salt marsh at La Perouse Bay, Manitoba on species composition, live standing crop and plant litter have been measured in a salt marsh. Each year from 1979 to 1984 a 5 x 5 m exclosure was established and maintained throughout the duration of the study. Vegetative measurements were taken in early August of 1982, 1983, and 1984 within each exclosure and on adjacent grazed sites. ...; Agrovoc Control Words: Riparian zones, Rangelands, Geese; View more details about this article

Title: Lesser snow geese and the nitrogen economy of a grazed salt marsh: Journal: Journal of Ecology; Authors: D. R. Bazely, and R. L. Jefferies; Date: 1989; Summary: To determine if nitrogen fixation replaces at least some of the incorporated nitrogen from forage plants into the tissue of lesser snow geese that graze on the tidal flats at La Perouse Bay, Manitoba (58ï¿½ 04ï¿½ N, 94ï¿½ 03ï¿½ W), acetylene-reduction technique was used to measure nitrogenase activity of surface sediments of a subarctic salt marsh. Nitrogenase activity was measured on two grazed and ungrazed sites. The first ungrazed site was excluded from grazing for four years and the second site has not been graze ...; Agrovoc Control Words: Riparian zones, Rangelands, Geese; View more details about this article

Title: Influences of livestock grazing on sage grouse habitat: Journal: Wildlife Society Bulletin; Authors: J. L. Beck, and D. L.

Title: Effects of spring grazing by greater snow geese on hay production: Journal: Journal of Applied Ecology; Authors: J. Bedard, A. Nadeau, and G. Gauthier; Date: 1986; Summary: Goose exclosures were used to determine the effects of spring grazing by migratory spring greater snow geese (Chen caerulescens atlantica) on June hay harvests in agricultural fields, along the St. Lawrence River near Montmagny, Quebec. A network of 51 sampling stations was established during the first week of April within the 213 ha productive area. At each station two sets of paired plots (ï¿½Aï¿½ and ï¿½Bï¿½) were established with one plot of each pairing grazed and one ungrazed. Vegetation sampling was conducted ...; Agrovoc Control Words: Riparian zones, Hay, Geese; View more details about this article
