Criteria

Question 1: Does species need conservation or recovery in England?
Response: Yes
Justification: About 25 extant localities in England, averaging 35 plants per colony. Just one population at Chappetts Copse, Hants, supports 80% of English population.
Question 2: Does recovery/ conservation depend on species-specific actions?
Response: Yes
Justification: The species survives best in open gladed woodland, with management (e.g. hay cut & rake) of ground vegetation & leaf litter mimicking traditional woodland management.
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: Within key areas (e.g. East Hampshire Hangers, lower Wye Valley) diversification of woodland management could benefit species - actions include general woodland thinning & glading (particularly corridors expanding and/or linking colonies), introduction of woodland meadow management, & introduction of intermittent woodland grazing combined with appropriate deer control.

Species Assessment

Current step on the Species Recovery Curve (SRC): 6. Recovery solutions trialled
Recovery potential/expectation: Medium-high
National Monitoring Resource: Combination - insufficient
Species Comments: Species has responded very well to targeted management at key sites. Need to roll out similar management to poorly managed localities

Key Actions

Key Action 1

Proposed Action: Monitor all populations on a 2 - 3 yearly basis, recording numbers of plants, inflorescences & % seed pod set. Record conditions of sites. Review future management in light of new findings.

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 with fewer than 20 plants

Comments: Ongoing action

Key Action 2

Proposed Action: Manage all English populations through programme of woodland thinning & glading; introduction of meadow management of ground vegetation (including leaf litter); protection from deer browsing; & hand pollination of flowers where appropriate.

Action targets: 7. Best approach adopted at appropriate scales

Action type: Habitat management

Duration: >10 years

Scale of Implementation: ≤ 20 sites

High priority sites:

Comments: Prioritise populations with < 20 plants

Key Action 3

Proposed Action: Review role of wood meadow management & wood pasture management in chalk & limestone woodlands, trialling different management protocols including grazing, hay cutting, & leaf litter removal etc. Record methodology & monitor / analyse results.

Action targets: 4. Autecology and pressures understood

Action type: Scientific research

Duration: >10 years

Scale of Implementation: ≤ 10 sites

High priority sites:

Comments: Species is a member of open, permanently gladed woodland species group that are significant decline in England
