Redington[13] Current: the enclosed land and house plots are owned by a number of local mainland families [14] Nothing quantifiable is known of the island's population prior to the 19th century.

The attached table presents details of the population and house data from the official government census returns, and Griffith's land valuation, between 1821 and 1981.

[19] In the 1860s, the lessee of the island's oyster beds was a Mr Wray, who described his methods and the success of his venture in some detail in his report to the Deep Sea and Coast Fishery Commissioners.

[21] Although the island is no longer populated (the last residents having left in the early 1980s), descendants of former occupants are living, and remain in contact through Facebook and other social media.

The long, low, drumlin-like ridge which forms the heart of the island appears to be composed mainly of glacial drift which was probably laid down during the last ice age.

[44] A comprehensive field survey of the island's vegetation has been undertaken by Messrs. Roden and Sheehy Skeffington and is forthcoming in The Irish Naturalists Journal.

Leo Hallisey, the organiser of Connemara Sea-Week, wrote: To see people dedicate time to a study like this just for the love of their work is an amazing concept in this day and age, when everything is so driven by money.

[52]Research to date has been conducted on the following: Terrestrial Vegetation, the Castle, the Children's Burial Ground, the Nausts and the Seaweed Mearing Stones and these topics have inspired a number of artistic responses - see below for publication details.

The following topics have been identified as worthy of investigation but await committed researchers: Lagoons, Vegetation & Ecology of the Salt Marshes, Cottage Garden Plants & Herbs, Terrestrial Fauna, Birds, Moths, Placenames, Social & Family History, the Architecture and Layout of the House Cluster, Ownership History, Poetry, Folklore, Poetry and Music.

Members of the Survey have presented results of their work individually in public lectures[53] and collectively at a half-day symposium in Letterfrack, in October 2012, during Connemara Sea-Week.

[54] Research results from The Discursive Survey of Island Eddy have been published as a series of 'Occasional Papers' and 'Artistic Responses' in diverse periodicals and books, and as downloadable 'Topical Memoranda'.
