Young Blonde Girl Posing On The Sandy Beach With Driftwood And Remains Of Trees

Most driftwood is the remains of trees, in whole or part, that have been washed into the ocean, due to flooding, high winds, or other natural occurrences, or as the result of logging. There is also a subset of driftwood known as drift lumber. Drift lumber includes the remains of man-made wooden objects, such as, buildings and their contents washed into the sea during storms, wooden objects discarded into the water from shore, dropped dunnage or lost cargo from ships (jetsam), and the remains of shipwrecked wooden ships and boats (flotsam). Erosion and wave action may make it difficult or impossible to determine the origin of a particular piece of driftwood.
Burning driftwood can produce polychlorinated dibenzodioxins (PCDDs), also known as the misnomer "dioxins", which are carcinogenic. For this reason burning driftwood is not recommended. The formation of PCDDs is well documented when organic compounds are combusted in the presence of chlorine, which is present in driftwood as a result of soaking in seawater.
Driftwood can be used as part of decorative furniture or other art forms, and is a popular element in the scenery of fish tanks.
