Title: Effects of livestock grazing on benthic invertebrates from a native grassland ecosystem: Journal: Freshwater Biology; Authors: G. J. Scrimgeour, and S. Kendall; Date: 2003; Summary: In Cypress Hills Provincial Park in Alberta, Canada, water quality, riparian vegetation and bank stability responses to livestock grazing were studied. Enclosures were established on three streams, while a fourth stream with long-term cattle exclusion (10-15 yr) was used as control. The short term exclusion results were pooled and compared to the one long-term exclusion results. Streams were then grazed for two summers.
