The Dyer Island Nature Reserve Complex is a protected area off the coast of Gansbaai in the Western Cape, South Africa. It consists of three islets, namely Dyer Island; Geyser Island; and Quoin Rock, that lies 25 km (16 mi) away from Dyer Island, off the coast of Quoin Point Nature Reserve and Agulhas National Park.[3][4][5]
Combined, Dyer Island and Geyser Island are a designated Ramsar site.[6]
Dyer Island is the largest in the group of islands, and lies about 8 kilometres (5.0 mi) offshore from Gansbaai and Danger Point Lighthouse. It is home to a declining colony of African penguins (≈ 5000 individuals in 2015). Geyser Island is a smaller island nearby and is home to around 60,000 brown fur seals.
The shallow channel between the two islands is popularly known as Shark Alley.
The reserve cannot be accessed by the general public.
History
[edit | edit source]The original name of Dyer Island was Ilha da Fera (Island of wild creatures), so named by Portuguese seafarers in the 15th century.
It is named after Samson Dyer, an emigrant from the US to the Cape Colony in 1806, who lived on the island collecting guano, which he sold to mainlanders as fertiliser.
In 1988, the two islands were named individually as Provincial Nature Reserves. And in 2019, the two islands were designated as a Ramsar site.
