Criteria

Question 1: Does species need conservation or recovery in England?
Response: Yes
Justification: Found at a few locations in the Brecks; declining
Question 2: Does recovery/ conservation depend on species-specific actions?
Response: Yes
Justification: Vulnerable to changes in management resulting in rank closed sward and scrubbing over. We lack knowledge on its autoecology and breeding habits
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: It has always been known only from a few sites in the Norfolk/Suffolk Brecks; likely a poor disperser and therefore unlikely to benefit from untargeted management

Species Assessment

Current step on the Species Recovery Curve (SRC): 2. Biological status assessment exists
Recovery potential/expectation: Low - Relict or natural rarity
National Monitoring Resource: Combination - insufficient
Species Comments: Pitfall trapping at two of its recent sites has failed to find it. Notoriously hard to find species; mostly subterranean. Requires warm dry, sheltered places with short sward and bare sandy ground. There may be a loose association with rabbits.

Key Actions

Key Action 1

Proposed Action: Field study to determine the extent of its population at its most recent sites and develop best practice methodology to find this species

Action targets: 3. National Monitoring Plan agreed and implemented

Action type: Targeted monitoring

Duration: 3-5 years

Scale of Implementation: ≤ 5 sites

High priority sites: Weeting Heath SSSI, Stanford Training Area SSSI, Lakenheath Warren SSSI, Cranwich Camp SSSI

Comments:

Key Action 2

Proposed Action: Where extant populations are found implement management to maintain short sward and bare ground mosaic by scarification or grazing. Fence off sensitive areas to allow rabbits to graze without pressures from dogs.

Action targets: 5. Remedial action identified

Action type: Habitat management

Duration: >10 years

Scale of Implementation: ≤ 5 sites

High priority sites: Weeting Heath SSSI, Stanford Training Area SSSI, Lakenheath Warren SSSI, Cranwich Camp SSSI

Comments:

Key Action 3

Proposed Action: Field study to determine the breeding ecology of D. vulneratus to see if there is a connection with rabbits.

Action targets: 4. Autecology and pressures understood

Action type: Scientific research

Duration: 3-5 years

Scale of Implementation: ≤ 5 sites

High priority sites: Weeting Heath SSSI, Stanford Training Area SSSI, Lakenheath Warren SSSI, Cranwich Camp SSSI
