Mangrove trees, adapted to saline coastal sediments, have found a home on the ol' SS Ayrfield, a WWII transport veteran.

The SS Ayrfield is something of a floating conservatory in Homebush Bay, Sydney, Australia. The ship was built in the UK in 1911 and launched as the SS Corrimal. During WWII, the 1,140-ton steel transport help supply U.S. troops in the Pacific, and later ran coal between Newcastle and Blackwattle Bay in Sydney Harbor. Note: The bay was name for the acacia trees (Black Wattle) growing along the bay used to build housing.

In 1972, the Ayrfield was sent to the Homebush Bay breaking yard in Sydney Harbor. Today, there are reportedly three other stripped, creaky old ship hulls afloat in Homebush Bay to keep Ayrfield company, although none sport mangrove trees.
