  1. Create scrapes and pools in wetlands and wet grasslands

    A study in 1940-1942 at a marsh site in Iowa, USA (Provost 1948), found that large numbers of dabbling ducks Anas spp. used pools and clearings created by blasting. Diving ducks Aythya spp. and ruddy ducks Oxyura jamaicensis, however, were rare in the newly-created pools as were American coot Fulica americana, rails Rallus spp. and sora Porzana carolina, instead being found in older ponds and clearings. Songbirds seemed largely unaffected by the blasting.
