Cronk y Bing

One of the widest strips of yellow dune on the island, good for birdwatching

Habitats: Sand dunes and shingle foreshore, waterside at the mouth of the Lhen Trench

Notable species: Pyramidal orchid and little tern.

Description: Marram grass (bent) dominates with a range of other plants including pyramidal orchid, sea bindweed, restharrow, common stork's-bill, harebell, sheep's-bit, wild carrot and burnet rose. Red goosefoot and saltwort are found on the shore.

The Lhen Trench, a largely canalised river draining part of the Ballaugh Curragh, runs along on edge of the reserve.

The adjacent shoreline is a favoured breeding ground for the little tern. Other breeding birds include oystercatcher, ringed plover and meadow pipit. During the autumn divers, grebes, sea duck, skuas, a variety of gulls and waders are often seen. Off the coast seals, basking sharks and diving gannets may also be seen.

In the past sand has been extracted from the back dunes, forming a flatter area behind the leading dunes upon which coastal grassland, grazed by rabbits, has developed.

Management: Erosion and accretion are being monitored. Cushag (common ragwort) is removed from the site and there are regular rubbish collections from the dunes.
