Solution holes eroded into the surface rock of the Everglades have long been thought to provide refuge for a wide variety of aquatic life, particularly during the dry season. Today, a variety of nonnative aquatic organisms inhabit these same areas, often in direct competition with native species.

This study examines the Rocky Glades habitat of eastern Everglades National Park over a three-year period of research. The work reveals a wealth of information on the movement and impacts of nonnative fishes to the ecology of the solution holes and surrounding marsh. The study provides important baseline data for monitoring the effects of future restoration efforts.
