Bleaker Island has been a sheep farm for over a hundred years. The island was managed by Arthur Cobb, a locally well-known agriculturalist and amateur naturalist, in the early 20th century who wrote a book on the subject, containing forty six of his own black and white photographs. The low aspect of the Island resulted in many ship-wrecks off the Island in the 19th and 20th centuries. There were five ship-wrecks on Bleaker Island in the first quarter of the 20th century. The most famous of these was the French tall ship 'Cassard' wrecked on the southern tip of the Island carrying a cargo of coal in May 1906. The Island has been run as an
organic sheep and cattle farm by Mike and Phyll Rendell since 1999, and has the small
Bleaker Island Settlement located on an
isthmus in the centre of its length. They built a self-catering cottage, "Cobb's Cottage", and a house there in 2000 called "The Outlook", and in 2011 they added a new house, called "Cassard House". They employ a farming couple who live there. In 2017 British writer
Nell Stevens published a memoir,
Bleaker House, about living on Bleaker Island for several months. ==Wildlife==
