Worldwide Species Action Plans
Populations of ring-necked pheasants (Phasianus colchicus) in the Midwest and many other grassland birds have declined in recent decades in response to loss of prime habitat (Warner et al. 1984,Warner and Etter 1986, Sauer et al. 2003). Many investigators have shown that pheasants preferentially nest and raise their broods in non-row crop herbaceous vegetation, especially grasslands, small grains, and hay (Hanson and Labisky 1964, Kuck et al. 1970, Hanson and Progulske 1973, Warner 1979, Ewing 1992). As the amount of row crops increased, both area available for nesting and chick survival rate declined (Warner et al. 1984).
