Upper Merced Watershed

The Merced River above Nevada Fall and South Fork Merced River above Wawona, numerous small meadows and adjacent riparian habitats occur. Owing their existence to the river and its annual flooding, these habitats help support eight special status animal species: harlequin ducks, black swifts, bald eagles, osprey, willow flycatchers, yellow warbler, western red bat, and Sierra Nevada mountain beaver.
