Criteria

Question 1: Does species need conservation or recovery in England?
Response: Yes
Justification: EN in GB & England.
Question 2: Does recovery/ conservation depend on species-specific actions?
Response: Yes
Justification: About 25 populations, largely in Cornwall (notably along the north Cornish coast), with four populations surviving in Devon post-2000. Endemic to Devon & Cornwall.
Question 3: At a landscape scale, would the species benefit from untargeted habitat management to increase habitat mosaics, structural diversity, or particular successional stages?
Response: Yes
Justification: Support (with technical guidance) management of suitable coastal cliff slope, heathland & commonland habitat is likely to benefit species.

Species Assessment

Current step on the Species Recovery Curve (SRC): 5. Remedial action identified
Recovery potential/expectation: Medium-high
National Monitoring Resource: Opportunistic - insufficient
Species Comments: Populations highly susceptible to changes in grazing pressure, & can fluctuate wildly. One Dartmoor population (Lydford High Down) declined from a maximum of 21,000 plants in 2002 to 100-200 by 2015 due to declines in grazing pressures. Works to increase cover of dwarf shrub communities (heather & gorse dominated) should avoid impacting populations of species characteristic of short, commonland grassland.

Key Actions

Key Action 1

Proposed Action: Monitor a sample of populations in stronghold areas, and all populations in non-stronghold/vulnerable areas, every <5 years. Assess population size & review condition of microhabitats in which it grows, determining impacts of changing grazing patterns where appropriate. Review future management based on findings.

Action targets: 3. National Monitoring Plan agreed and implemented

Action type: Status survey/review

Duration: 6-10 years

Scale of Implementation: ≤ 20 sites

High priority sites: All sites away from stronghold along north Cornish coast between Hayle & Perranporth

Comments:

Key Action 2

Proposed Action: Ensure effective grazing regimes (of correct stock) of heathland and acid commonland, to ensure that sites remain well-grazed, with abundant microsites for seedling establishment.

Action targets: 6. Recovery solutions trialled

Action type: Habitat management

Duration: >10 years

Scale of Implementation: ≤ 20 sites

High priority sites: All.

Comments: Species favours short open mildly acid grassland, with high levels of grazing. Some sites are undergrazed & suffering from growth of dwarf shrubs & trees/bushes. Conversely, heavy sheep grazing may not be ideal for species (though heavy pony / cattle grazing likely to be highly beneficial)

Key Action 3

Proposed Action: Promote the short turf favoured by E. vigursii & associated species in suitable habitats for this species

Action targets: 5. Remedial action identified

Action type: Landscape/catchment/marine management

Duration: Unknown

Scale of Implementation: ≤ 20 sites

High priority sites: Dartmoor SSSIs
