Follow two scientists as they spend a night in the Everglades collecting water samples, photographing wildlife, and sloshing through marshes in an attempt to understand this mysterious ecosystem. Part of a long-term effort to return the Everglades to a natural state after a century of development, the scientists try to figure out what the "river of grass" was like prior to human settlement. Along the way, they deal with razor-sharp sawgrass and alligators and turtles and are even surprised by the sudden presence of what is known in the Everglades as a "frog gigger"-one who hunts and collects frogs for food! Published in cooperation with the Long Term Ecological Research Network, which is funded by the National Science Foundation. In this enhanced edition, enjoy read-along and colorful animations that bring this story to life!
