Criteria

Question 1: Does species need conservation or recovery in England?
Response: Yes
Justification: Known from fewer than 10 sites in England, with overall population numbering <100 plants (possibly considerably less). Number of flowering plants annually <10 spikes.
Question 2: Does recovery/ conservation depend on species-specific actions?
Response: Yes
Justification: This Critically Endangered species survives in Fagus woodland with exacting ecological requirements (notably light levels). All populations very small. Flowering & seed production very poor.
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: No
Justification: This species would not benefit from untargeted management

Species Assessment

Current step on the Species Recovery Curve (SRC): 4. Autecology and pressures understood
Recovery potential/expectation: Low - Extinction debt
National Monitoring Resource: Opportunistic - sufficient
Species Comments: Performing poorly at present, though some 'lost' populations rediscovered in recent years. A species of dappled high beech woodland & beech coppice, with exacting requirements relating to light levels, density of ground vegetation, levels of leaf litter deposition, geology and plant-insect relationships (re pollination). Subject of existing species-specific steering group.

Key Actions

Key Action 1

Proposed Action: Monitor all populations annually, recording total number of plants, no. of flowering spikes, effective seed pod production, & site conditions (likely to be carried out by site wardens or local volunteers). Ensure monitoring is suited to data analysis.

Action targets: 3. National Monitoring Plan agreed and implemented

Action type: Targeted monitoring

Duration: >10 years

Scale of Implementation: ≤ 10 sites

High priority sites: All sites

Comments: Close annual monitor will ensure that necessary action can be undertaken in a timely manner, providing analysis shows what actions are required.

Key Action 2

Proposed Action: Investigate genetics, and ecological parameters at all sites, including geology; aspect; light levels through day & associated temperature; predation by deer, molluscs etc; beneficial or detrimental role of leaf litter etc. Analyses results & share with other site managers.

Action targets: 4. Autecology and pressures understood

Action type: Scientific research

Duration: >10 years

Scale of Implementation: ≤ 10 sites

High priority sites: All sites

Comments: Urgent need to better understand how management activities influence both production of above-ground stems and flowering success.

Key Action 3

Proposed Action: Manage all sites with aim to gently increase light levels; manage ground vegetation & leaf-litter build up (through annual hay cuts/rakes); protect plants from damage/destruction by predators (or clumsy visitors); & undertake sustainable hand pollination to ensure effective seed-set. Suitable microhabitats should be expanded where possible to ensure that all suitable ground is in a favourable state for the species. Any ex-situ work to better understand germination of this intractable species should ideally use trial material from larger European populations, and should adhere to agreed guidelines if limited quantities of seed are removed from English sites.

Action targets: 6. Recovery solutions trialled

Action type: Habitat management

Duration: >10 years

Scale of Implementation: ≤ 10 sites

High priority sites: All sites

Comments: Management intensity (e.g. light levels) should be gradually increased giving time for response from plants to take place & the efficacy of management assessed
