Native American Salt Basins in the Sierra Nevada
Native Americans of the Miwok tribe in the northern Sierra Nevada, California carved these basins into the granite bedrock to produce salt for trade. They filled the basins with water from a salt spring and let the water evaporate, leaving a salt residue in the basin.

Invasive Lionfish Removal
The invasive red lionfish (Pterois volitans) waits to be hauled to the surface, where it will eventually be used by NOAA to conduct lab studies on lionfish reproductive biology, age, and growth.

Anhinga Drying Its Feathers
Anhingas are considered primitive birds because they do not produce oils like ducks and other water fowl. They must dry their feathers periodically in order to fly or even remain buoyant, so they remain perched for significant periods of time with wings outstretched.

Great Blue Heron
Great Blue Herons are found throughout much of North America, but are always associated with water. Because they fish by sight, they need relatively shallow water. Release of too much water through the canals north of the Everglades can interfere with their ability to find food.
