Photo by @CarltonWard | Northwest Florida is said to have the highest concentration of freshwater springs in the world. Unfortunately, in many of Florida’s springs, eelgrass and other native vegetation has been overgrown and displaced by toxic green algae, seen here blanketing the bottom of Manatee Springs and ensconcing a manatee searching for food, as biologist Joe Guthrie (@joeguthrie8) observes from above. The proliferation of algae in recent years is attributed to increased pollution in springsheds and over pumping of the aquifer that has reduced spring flows to further concentrate pollutants. This photograph was captured on day 20 of the 70-day, 1000-mile Florida Wildlife Corridor #Glades2Gulf Expedition, a National Geographic supported project that traced the best remaining wildlife corridor connecting the Everglades Headwaters near Orlando to the vast pine forests of the Florida panhandle and Alabama.
