Effects of cattle grazing intensity on water chemistry, aquatic invertebrates, waterbirds, songbirds and amphibians of pothole ponds of the Aspen Parkland, Central Alberta / Richard J. Casey, Cynthia A. Paszkowski, Sharon A. Kendall, Norine Ambrose and Beverly Gingras.
Material type: TextPublication details: Edmonton, AB : 1999. Alberta Research Council,Description: vii, 79 p. : ill. (some col.) ; 28 cmOnline resources: Abstract: Small semi-permanent and permanent pothole ponds are common in the aspen parkland ecoregion of central Alberta. The ponds are major breeding and staging areas for waterfowl and they provide important habitat for other wildlife that rely on wetlands. Cattle grazing is often the main agricultural practice in this region. Management of the ponds are primarily the responsibility of landowners and conservation agencies.However, there is little scientific knowledge to help in managing these important wetlands, especially effects related to cattle grazing.Previous studies on the wildlife-grazing interactions in pothole ponds have been almost exclusively conducted in uplands. Few studies appear to have examined the effects of grazing on aquatic invertebrates or amphibians in ponds. Aquatic invertebrates are important in food webs,nutrient cycling and the productivity of wetland systems. Our study complements the work of the Ducks Unlimited and North American Waterfowl Management Plan thatItem type | Current library | Collection | Call number | Status | Date due | Barcode |
