Criteria

Question 1: Does species need conservation or recovery in England?
Response: Yes
Justification: Restricted to England. Extremely localised with only five verified hectads post-1980. It has undergone a decline in range over preceding decades and there is no reason to think that that decline is not continuing to the present day, with probably only one locality remaining which is likely support the species.
Question 2: Does recovery/ conservation depend on species-specific actions?
Response: Yes
Justification: Extremely localised and probably still declining to the extent that it might now occupy only one location. Vulnerable to coastal habitat loss due to climate change and with poorly understood habitat requirements this species urgently requires targeted management and site protection
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): 7. Best approach adopted at appropriate scales
Recovery potential/expectation: Low - Extinction debt
National Monitoring Resource: Opportunistic - insufficient
Species Comments: This is a coastal species dependent on litter on sandy or stony soils.

Key Actions

Key Action 1

Proposed Action: Review historical and current management at existing locations and undertake literature reviews to characterise the range of micro-habitats within which it is found, particularly the nature of suitable substrates and the availability of vegetation litter. The reviews should help identify the nature and quality of suitable coastal habitats and their management requirements, as well as the pressures from climate change which might result in further declines such as sea-level rise.

Action targets: 4. Autecology and pressures understood

Action type: Scientific research

Duration: 2 years

Scale of Implementation: ≤ 5 sites

High priority sites: Dungeness

Comments: Actions 1 and 2 are related.

Key Action 2

Proposed Action: Depending on the results of the autecological study and site management reviews restore suitable substrates and conditions for promoting the deposition of vegetation litter. This might require invasive techniques such as ground scarification and/or mechanical excavation and the deposition of new substrates.

Action targets: 7. Best approach adopted at appropriate scales

Action type: Habitat management

Duration: 3-5 years

Scale of Implementation: ≤ 5 sites

High priority sites: Dungeness

Comments: Successful management should be followed by action 3.

Key Action 3

Proposed Action: Subject to the findings of the autecological review assess potential for re-introduction to historical locations using the most robust existing populations as a donor source following the introduction of suitable management. Consider ecological requirements of the species, suitability of site (e.g. subject to ongoing threats and/or climate change effects), timing of release and the need for ongoing habitat management. No information could be found on the feasibility of such re-introductions nor the techniques necessary for success.

Action targets: 6. Recovery solutions trialled

Action type: (Re-)introduction

Duration: 3-5 years

Scale of Implementation: ≤ 5 sites

High priority sites: Dungeness and historical locations.

Comments: translocation may be premature until current status, autecology and reasons for decline are understood.
