Botrychium lunaria (Moonwort)
A small fern, often occurring singly or in small populations. It prefers well-drained sites, usually with a high base-content, although it can occur on more acidic substrates. Habitats include meadows, pastures, open woodland, sand dunes and grassy rock ledges. It can also colonise slag heaps and quarry spoil. 0-1065 m (Ben Lawers, Mid Perth).
B. lunaria was lost from many lowland sites before 1930, and this loss has continued, particularly in N. England, due to grassland improvement and scrub invasion. There appear to have been some losses in upland areas, but the species can easily be overlooked and may therefore be under-recorded.
Circumpolar Boreo-temperate element.
