SHETLAND: The Keen of Hamar
The Keen of Hamar is a nature reserve on the island of Unst, in Shetland, Scotland. It is famous for its rare and unique plants that grow on the serpentine rock, which was formed deep under the sea millions of years ago. The reserve is managed by Scottish Natural Heritage and is protected as a Site of Special Scientific Interest and a Special Area of Conservation.
One of the most remarkable plants that can be found in the Keen of Hamar is the Edmondston's chickweed, also known as Shetland mouse ear. This white-flowered plant is endemic to Unst and was discovered by a young botanist named Thomas Edmondston in the 19th century. He died tragically at the age of 20 on an expedition to South America, but his legacy lives on in this plant that bears his name.
Other plants that have adapted to the harsh conditions of the Keen of Hamar include the Norwegian sandwort, the mountain everlasting and the sea plantain. These plants show peculiar growth forms and colours that are different from their relatives elsewhere. They can survive on the thin and nutrient-poor soil that covers the serpentine rock.
The Keen of Hamar can be visited by following a circular route that starts from a car park near Littlehamar. The walk offers stunning views of the coast and cliffs, as well as a chance to see some of the rarest plants in Britain. The best time to visit is from mid-May to early July, when the flowers are in bloom.
