A riparian forest or riparian woodland is a forested or wooded area of land adjacent to a body of water such as a river, stream, pond, lake, marshland, estuary, canal, sink or reservoir.
The term riparian comes from the Latin word ripa, 'river bank'; technically it refers only to areas adjacent to flowing bodies of water such as rivers, streams, sloughs and estuaries.
However, the terms riparian forest and riparian zone have come to include areas adjacent to non-flowing bodies of water such as ponds, lakes, playas and reservoirs.
Riparian forests help control sediment, reduce the damaging effects of flooding and aid in stabilizing stream banks.
Many not only tolerate it, but require it in order to maintain health and complete their lifestyles.
