The Everglades are a complex system of interdependent ecosystems. The area recognized as the Everglades, prior to drainage, was a web of marshes and prairies 4,000 square miles in size. Borders between ecosystems are subtle or imperceptible. These systems shift, grow and shrink, die, or reappear within years or decades. Geologic factors, climate, and the frequency of fire help to create, maintain, or replace the ecosystems in the Everglades. The system begins near Orlando with the Kissimmee River, which discharges into the vast but shallow Lake Okeechobee.
Wet to very damp habitats are commonly found in Finland. These bear several hydrophytic (water-loving) species adapted to these wet conditions. Various mosses and vascular plant species from the Genus Carex (Sedge family / Cyperaceae) are frequently found. Forest marshes and swamps and ponds offers a unique biohabitat of water-loving plant species, numerous insects (especially their larvae) and Protozoa (single-celled organisms living in water)
