Summary of Methods: Lapointe et al. looked at the effects of a rotational grazing system on the nesting success of ducks on islands within the St. Lawrence River in Quebec. Dense nest cover (DNC) was achieved by planting new grass species to help aid the establishment of more nesting ducks. When switched to a rotational grazing system, nesting success increased in idle pastures, but not in the DNC pastures the first year. Two years later, after the DNC established itself, nesting was most successful in one of the DNC pastures. Other studies have shown that DNC becomes over grown in 7-8 years, so the rotational grazing system would be effective in keeping the vegetation at a manageable density.
