Eyebright biology

This species seems to have evolved by crossing between two different species of eyebright; Euphrasia anglia and Euphrasia miracantha (2). During the Middle Ages, the related species Euphrasia officinalis was used to brighten the eyes, hence the common name 'eyebright' (4).

Top

Eyebright range

Occurs in Devon, where it has always been rare, and in Cornwall (3).

You can view distribution information for this species at the National Biodiversity Network Gateway.
Top

Eyebright habitat

Grows on bristle brent (Argostis curtisii) and western gorse (Ulex galli) heathlands (3). The species requires fairly open conditions and short grass created by grazing or burning to keep the gorse and heather in check (3). It often occurs alongside paths in coastal areas, where regular trampling maintains open conditions (2).

Eyebright status

Vulnerable in Great Britain (2).

Top

Eyebright threats

Habitat destruction has resulted in the loss of this plant at a number of sites in inland Cornwall (5). Grazing maintains the open conditions favoured by this species, so the widespread decline in grazing poses a threat (5).

Eyebright conservation

There are two sites on Dartmoor where this species occurs. Suitable habitat management is underway at both sites (3).

The UK Biodiversity Action Plan for this species is available at UK BAP.
There may be further information about this species available via the National Biodiversity Network Gateway.
