Criteria

Question 1: Does species need conservation or recovery in England?
Response: Yes
Justification: Only a small number of recent records and appears to have declined. However, this is a small, easily overlooked species and under-recording is an important factor.
Question 2: Does recovery/ conservation depend on species-specific actions?
Response: Yes
Justification: Info from seabird census needed. Long term non significant increase Eng BBS (25 yr +23%, 10 yr +7%). Eng WeBS trends (25 yr +74%, 10 yr +33%). Seabirds Count = a 6% increase in English population; coastal -13%, inland +30% Revised upon review that population is stable so conservation is not required at this stage.
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: Seems to rely on organic matter on coastal shingle, sandy expanses and saltmarsh. Development, coastal erosion and beach cleaning may all negatively impact this species.

Species Assessment

Current step on the Species Recovery Curve (SRC): 2. Biological status assessment exists
Recovery potential/expectation: Unknown
National Monitoring Resource: Opportunistic - insufficient
Species Comments: Only a small number of recent records, but this is a small, easily overlooked species. Very little known of the ecology of the adults and larvae.

Key Actions

Key Action 1

Proposed Action: Define autecology of larvae and adults at known sites.

Action targets: 4. Autecology and pressures understood

Action type: Scientific research

Duration: 3-5 years

Scale of Implementation: ≤ 5 sites

High priority sites: Chesil Beach

Comments: What are micro-habitat preferences and diet of the adults and larvae? What are the dispersal abilities of the adults? Reliable identification of larvae may only be possible using molecular tools.
