Claim: The South Florida rocklands eco region covers 2,100 kilomters and is located in Florida and the Florida Keys, where their forests form on limestone outcrops.
Evidence: The South Florida rocklands ecoregion, in the tropical and subtropical moist broadleaf forests biome, occurs in southern Florida and the Florida Keys in the United States, where they would naturally cover an area of 2,100 km (810 sq mi). These forests form on limestone outcrops with very thin soil; the higher elevation separating them from other habitats such as coastal marshes and marl prairies.
