Show These annual plants produce enormous amounts of seeds in addition to their foliage which makes them a valuable plant used extensively by all the sparrows, mourning doves, hungarian partridge, blackbirds, juncos, goldfinch, chipmunks and ground squirrels. Plants It is used in large amounts by gadwall, coot, and widgeon, and to a lesser extent by pintail, mallard, redhead, shoveller, and teal. It is used principally by the diving birds: coot, redhead, scaup, ruddy, and also by widgeon, pintail, teal and mallards. Although these plants may be used as cover, they have little value to waterfowl other than geese which eat the roots, and are, therefore, usually regarded as undesirable since they take the place of more desirable plant species. These plants are without exception the most valuable single food plant for waterfowl, particularly for the following species: whistling swan, Canada goose, redhead, canvasback, scaup, coot, mallard, shoveller, gadwall, widgeon, teal, and the following shorebirds, avocet, godwit, and dowitchers. This grass is often associated with pondweeds. This plant rates as one of the most valuable species of marsh plants used by the same species that utilize pondweeds in a similar degree. This is a valuable plant used for nesting and food by shoveller and cinnamon teal and for food by Canada geese and ground squirrels. These are used extensively by waterfowl and shorebirds, especially the following species, for cover and food: canvasback, mallard, gadwall, pintail, redhead, ruddy, shoveller, teal, Canada and snow geese, godwits, and rails. |
