Criteria

Question 1: Does species need conservation or recovery in England?
Response: Yes
Justification: VU in GB & England. Widely scattered in Cornwall & Devon (W of River Exe), otherwise very rare in Somerset, Dorset, Hampshire & Sussex
Question 2: Does recovery/ conservation depend on species-specific actions?
Response: Yes
Justification: Targeted management (coppicing, tree felling, management of ridesides / road verges etc) may be necessary in more easterly sites outside strongholds of 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: Sympathetic, active management of woodland likely to benefit species, particularly in stronghold areas

Species Assessment

Current step on the Species Recovery Curve (SRC): 6. Recovery solutions trialled
Recovery potential/expectation: Medium-high
National Monitoring Resource: Opportunistic - insufficient
Species Comments: The species is one of open, managed deciduous woodland on light mildy acidic soils. Whilst plants are probably long-lived, it can respond well to management, germinating freely from seed: however survival of seedlings in formative years depends on management of ground vegetation & limiting of leaf litter deposition.

Key Actions

Key Action 1

Proposed Action: Monitor a sample of populations in stronghold areas, and all populations in non-stronghold/vulnerable areas. Record number of flowering & non-flowering plants, plus condition of sites.

Action targets: 3. National Monitoring Plan agreed and implemented

Action type: Targeted monitoring

Duration: >10 years

Scale of Implementation: National

High priority sites: Post-1980 sites in Dorset, Hampshire, Somerset & Sussex

Comments: Record number of flowering plants, presence of seedlings / non-flowering plants, site conditions incl. light levels, density & cover of ground vegetation & leaf litter

Key Action 2

Proposed Action: Manage selected English populations (particularly outside strongholds of Cornwall & Devon) through programme of woodland thinning & glading; introduction of wood meadow management of ground vegetation (including leaf litter) etc.

Action targets: 6. Recovery solutions trialled

Action type: Habitat management

Duration: >10 years

Scale of Implementation: ≤ 20 sites

High priority sites:

Comments: Species responds positively to woodland management work that increases light levels, creates niches for seedling establishment, & controls vigorous competitive ground flora species

Key Action 3

Proposed Action: Research seed longevity (in soil seed bank etc) & undertake management at former sites to restore 'lost' populations

Action targets: 5. Remedial action identified

Action type: Habitat management

Duration: 3-5 years

Scale of Implementation: ≤ 10 sites

High priority sites:

Comments: Focus on sites outside core range, in counties such as Dorset, Hampshire & Sussex.
