The surrounding pastureland (machair) is rich in wild flowers, wild orchids, butterflies, bees and seasonal breeding birds.
Machair is a Gaelic word meaning fertile low lying grassy plain. This is the name given to one of the rarest habitats in Europe which only occurs on exposed western coasts of Scotland and Ireland. Machair habitats in the Outer Hebrides run up the western shores of Uist, Harris and Lewis.
Here sand, largely made up of crushed shells, is regularly blown ashore by Atlantic gales. Over time the calcium rich shell sand and traditional Outer Hebrides crofting land practices have led to the development of a mosaic of fertile Scottish grassland habitats renowned for its Outer Hebrides wildflowers, Western Isles birds and insect life.
Great Yellow Bumble Bee
One of the rarest British bumblebees, now restricted to machair and other flower-rich areas in the Orkneys, Scottish islands, and Caithness and Sutherland. The species appears to have a particular association with red clover.
