Reduce grazing intensity Bird Conservation

A before-and-after study in an 8,357 ha grassland site under rest-rotation grazing since 1967 in Montana, USA (Mundinger 1976), found that the number of wildfowl nesting on the site, the species richness and the number of broods produced all increased  between 1970 and 1973-4 (190 pairs of seven species producing 127 broods in 1970 vs. 270 pairs of 12 species producing 191 broods in 1974). The grazing regime involved five areas of the site being grazed at different times each year to allow the vegetation to recover. The highest densities of wildfowl were found in areas that had been rested in the previous year.
