Criteria

Question 1: Does species need conservation or recovery in England?
Response: Yes
Justification: VU in GB & England. Confined to two areas in Britain - the western Mendips & Torbay limestones. Locally abundant, but with small & localised populations away from the main populations
Question 2: Does recovery/ conservation depend on species-specific actions?
Response: Yes
Justification: Populations at some sites highly localised (in some cases to a few square metres): these sites would benefit from targeted action to clear scrub & gorse, etc
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): 5. Remedial action identified
Recovery potential/expectation: Medium-high
National Monitoring Resource: Opportunistic - insufficient
Species Comments: Large population occur at Brean Down (Mendips) and Berry Head (Torbay limestones). Smaller populations exist at three further locations. Responds well to management, germinating freely from buried seed following scrub clearance. Intense summer droughts & heavy levels of sheep grazing can damage populations, which typically recover quickly under better conditions.

Key Actions

Key Action 1

Proposed Action: Monitor isolated populations at smaller sites on a 5 yearly basis, recording number of flowering plants, presence of seedlings, vegetation structure, threats (e.g. from non-native invasives) etc

Action targets: 3. National Monitoring Plan agreed and implemented

Action type: Status survey/review

Duration: 3-5 years

Scale of Implementation: ≤ 5 sites

High priority sites: Berry Head to Sharkham Point SSSI. Daddyhole SSSI. Hope's Nose to Wall's Hill SSSI. Brean Down SSSI. Purn Hill SSSI.

Comments: Monitoring should be used to review state of population & quality of habitat, & inform future management decisions.

Key Action 2

Proposed Action: Maximise area available for colonisation by H. apenninum through programme of active management of extant sites, & restoration / linkage with nearby 'lost' populations through scrub clearance, appropriate levels of grazing & linkage of microhabitats favoured by this species. Research should be undertaken into best grazing stock to maintain this species & other rarer species for which these sites are of national importance.

Action targets: 6. Recovery solutions trialled

Action type: Habitat management

Duration: 3-5 years

Scale of Implementation: ≤ 5 sites

High priority sites: Berry Head to Sharkham Point SSSI. Daddyhole SSSI. Hope's Nose to Wall's Hill SSSI. Brean Down SSSI. Purn Hill SSSI.

Comments: Species typically confined to rather restricted populations at some sites such as Daddyhole SSSI - which in some cases cover just a few square metres & are threatened by encroachment of scrub & coarse grasses / forbs.
