FIELD NOTES    The south bank of the Kasilof River estuary attracts many of the same birds, fish and mammal species as does the north shore. But a more extensive salt marsh reaches further into a bend of the river, and the shoreline may be steeper and less sandy due to greater exposure to Cook Inlet. As the beach curves into the river mouth, the exposure changes from west to north, offering a chance to investigate whether birds have taken shelter during high surf and wind. Sandhill cranes stage and sometimes nest in the marsh, and migrating geese and ducks visit in spring and fall. Shorebirds work the tide line, refueling for migration. In winter, the extensive flats behind the dunes are a favorite haunt of snow buntings. Beluga whales have been seen moving a short distance offshore in pursuit of returning salmon.

HABITAT    Several distinct habitats occur relatively close to each other. A tidally influenced beach rims the shore and curves into the river mouth. The estuary draws both marine and freshwater species. The salt marsh with sedges, grass, and brush transitions in a short span to black spruce wetland and then into a lowland forest dominated by white spruce, black cottonwood and paper birch. Extensive edges between open and forested habitat are visible from the mouth.

RECREATION CONNECTION     Personal use salmon fishing by Alaska residents draws hundreds of people to the beach each July.

VIEWING TIP High tide concentrates the shore birds, as tides recede they spread out to feed.
