. . Public transportation The geology of South Florida together with a warm wet subtropical climate provides conditions well-suited for a large marshland ecosystem Layers of porous and permeable limestone create water-bearing rock and soil that affect the climate weather and hydrology of South Florida the properties of the rock underneath the Everglades can be explained by the geologic history of the state the crust underneath Florida was at one point part of the African region of the supercontinent Gondwana About 300 million years ago North America merged with Africa connecting Florida with North America Volcanic activity centered on the eastern side of Florida covered the prevalent sedimentary rock with igneous rock Continental rifting began to separate North America from Gondwana about 180 million years ago When Florida was part of Africa it was initially above water but during the cooler Jurassic Period the Florida Platform became a shallow marine environment in which sedimentary rocks were deposited Through the Cretaceous Period most of Florida remained a tropical sea floor of varying depths the peninsula has been covered by seawater at least seven times since the bedrock formed. Some of the driest land in the Everglades is pineland (also called pine rockland) ecosystem located in the highest part of the Everglades with little to no hydroperiod Some floors however may have flooded solution holes or puddles for a few months at a time the most significant feature of the pineland is the single species of South Florida slash pine (Pinus elliottii) Pineland communities require fire to maintain them and the trees have several adaptations that simultaneously promote and resist fire the sandy floor of the pine forest is covered with dry pine needles that are highly flammable South Florida slash pines are insulated by their bark to protect them from heat Fire eliminates competing vegetation on the forest floor and opens pine cones to germinate seeds a period without significant fire can turn pineland into a hardwood hammock as larger trees overtake the slash pines the understory shrubs in pine rocklands are the fire-resistant saw palmetto (Serenoa repens) cabbage palm (Sabal palmetto) and West Indian lilac (Tetrazygia bicolor) the most diverse group of plants in the pine community are the herbs of which there are two dozen species These plants contain tubers and other mechanisms that allow them to sprout quickly after being charred.
