Criteria

Question 1: Does species need conservation or recovery in England?
Response: Yes
Justification: EN in GB (2023). Still thriving in New Forest & Dorset, but rare & declining elsewhere
Question 2: Does recovery/ conservation depend on species-specific actions?
Response: Yes
Justification: Targeted actions needed in non-stronghold areas where species is vulnerable to extinction.
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: Continued expansion of traditional grazing & associated disturbance in current & former heathland areas likely to benefit species & to allow development of metapopulations.

Species Assessment

Current step on the Species Recovery Curve (SRC): 5. Remedial action identified
Recovery potential/expectation: Medium-high
National Monitoring Resource: Combination - insufficient
Species Comments: A short growing species of wet heath & valley mire, & mineral quarries in England, reliant on grazing and/or disturbance to maintain open conditions favoured by species.

Key Actions

Key Action 1

Proposed Action: Develop a standardised monitoring protocol suitable for the clonal nature of the plant and one which captures fecundity/recruitment. Monitor a sample of populations in stronghold areas, and all populations in non-stronghold/vulnerable areas on 3-5 year basis, assessing history of species at site & reviewing site conditions

Action targets: 3. National Monitoring Plan agreed and implemented

Action type: Targeted monitoring

Duration: 6-10 years

Scale of Implementation: National

High priority sites: Sites in Weald, Thames Basin, Devon, Cornwall, Norfolk & wider Lake District area

Comments: Many sites away from main heathland strongholds on areas recently disturbed by human activity (e.g. forestry rides, quarries & settling lagoons, horse riding routes), & perhaps transient in nature.

Key Action 2

Proposed Action: Maintain / restore extensive heathland grazing at all extant & post-1950 sites, seeking to ensure sufficient microhabitats of seasonally-damp poached/disturbed microhabitats on peats & clays. Conservation efforts should seek to link isolated/scattered populations through establishment of larger grazing / management units.

Action targets: 7. Best approach adopted at appropriate scales

Action type: Habitat management

Duration: >10 years

Scale of Implementation: National

High priority sites: as for action 1

Comments: Targeted action in the Thames Basin Heaths (Hampshire), Hensbarrow (Cornwall) & elsewhere has resulted in restoration & expansion of small or 'lost' populations

Key Action 3

Proposed Action: Through advice and support, provide guidance on habitat management requirements for this species at reclaimed sites (from mining, forestry, agriculture etc.)

Action targets: 7. Best approach adopted at appropriate scales

Action type: Advice & support

Duration: >10 years

Scale of Implementation: National

High priority sites: China clay areas of Dartmoor, Bodmin Moor n& Hensbarrow NCAs

Comments: Some of England's largest populations occur within forestry plantation & mineral extraction sites & are especially vulnerable to destruction through site operations (and lack of conservation protection).
