Brine Shrimp
One of the most popular and important species in Great Salt Lake State Park is the brine shrimp. These tiny crustaceans can survive in extreme environments, and form a crucial part of the lake's ecosystem. Visitors are often amazed to watch these creatures swimming around in what appears to be a barren environment.
The population of brine shrimp fluctuates depending on the water level of the Great Salt Lake. During periods of high levels, brine shrimp reproduce quickly and in large numbers. They also provide food for many birds and fish that live in the lake.

Brine Flies
Brine flies are another important species found in Great Salt Lake State Park. These small insects feed on the brine shrimp, providing more food for birds and fish. They also act as an important source of protein for shorebirds and other wildlife that live near the lake.
Visitors often don’t realize the importance of these tiny insects until they observe them in great numbers. During mating season, these small flies create a large buzzing sound as they swarm the shoreline of the lake.
Waterfowl
The park also provides an important habitat for a wide variety of migratory waterfowl. This includes species such as the American Wigeon, Northern Shoveler, and Tundra Swan. These birds travel long distances to take advantage of the rich food sources in the Great Salt Lake.
Visitors can also spot white pelicans, tundra swans, American bitterns, and many other species along the shoreline of the lake. During warmer months when water levels are higher, the shore is teeming with life.
