  1. Create scrapes and pools in wetlands and wet grasslands

    A before-and-after study on a marshland site near Lake Manitoba, Manitoba, Canada (2), found that between the summers of 1965 and 1966 there was a 288% increase in the number of wildfowl using 25 ponds created by blasting in August 1964 and 1965. There was a smaller increase at natural marshlands nearby. A total of 11 species were seen, mostly of dabbling ducks Anas spp. Ponds averaged 132 m2 and 1.5 m deep.
