'Driftwood' is
wood that has been washed onto a shore or beach of a sea or river by the action of winds, tides, waves or man.
In some
waterfront areas, driftwood is a major nuisance. However, the driftwood provides shelter and food for birds, fish and other aquatic species as it floats in the ocean.
Gribbles,
shipworms and
bacteria decompose the wood and gradually turn it into nutrients that are reintroduced to the
food web. Sometimes, the partially decomposed wood washes ashore, where it also shelters birds, plants, and other species. Driftwood can become the foundation for
sand dunes.
Driftwood can be formed from:
★ a
tree or tree branch washed into the
ocean (or another large body of water), usually because of strong winds, as in a storm, or due to
flooding.
★ buildings and their contents washed into the sea by
floods, storms and
tsunamis.
★ wooden objects discarded into the water from shore.
★ remains of wrecked wooden ships and boats.
★ jettisoned
dunnage or lost
cargo.
In history
According to
Norse mythology, the first humans,
Ask and Embla, were formed out of two pieces of driftwood, an
ash and an
elm, by the god
Odin and his brothers,
Ve and
Vili.
Driftwood carried by
Arctic rivers was the main, or sometimes only, source of wood for some
Inuit and other Arctic populations living north of the
tree line until they came into regular contact with
European traders.
One famous piece of driftwood is the "
Old Man of the Lake" in
Crater Lake,
Oregon. This is a full-size tree that has been bobbing vertically in the lake for more than a century.
[1] Due to the cold water of the lake, the tree has been well preserved.
Many people use driftwood as parts of decorative
furniture or other
art forms, and it is a popular element in the scenery of fish tanks.
Driftwood sculpture
Sculpture made of driftwood has been constructed on beaches or
mudflats.
★ One location has been at
Kullaberg,
Sweden, where Lars Vilke created
Nimis a controversial driftwood artwork in the year 1980. This sculpture and two others ultimately led to the declaration of
Ladonia as an independent nation.
★ Sculptures were created on the
Emeryville, California mudflat and marsh area of
San Francisco Bay in the late 1960s.
