Uros island in Lake Titicaca

A *floating island* is a mass of floating aquatic plants, mud, and peat
ranging in thickness from a few inches to several feet. Floating islands
are a common natural phenomenon that are found in many parts of the world.
They exist less commonly as a man-made phenomenon. Floating islands are
generally found on marshlands, lakes, and similar wetland locations, and
can be many hectares in size.

*Natural occurrences[edit]*

Sometimes referred to as /tussocks/, /floatons/, or /suds/, natural
floating islands are composed of vegetation growing on a buoyant mat of
plant roots or other organic detritus. Some cenotes in northern Mexico have
natural floating islands.

They typically occur when growths of cattails, bulrush, sedge, and reeds
extend outward from the shoreline of a wetland area. As the water gets
deeper the roots no longer reach the bottom, so they use the oxygen in
their root mass for buoyancy, and the surrounding vegetation for support to
retain their top-side-up orientation^[/citation needed/]. The area beneath
these floating mats is exceptionally rich in aquatic lifeforms. Eventually,
storm events tear whole sections free from the shore, and the islands thus
formed migrate around a lake
