Criteria

Question 1: Does species need conservation or recovery in England?
Response: Yes
Justification: Requires a survey to assess threats and priorities in England where it has certainly declined. Once known from 13-15 sites on North Somerset and North Devon coasts but with only 4 post-2000 records. Also recorded in perhaps 16 sites in Wales where it is still locally plentiful on the coast but rare in the Brecon Beacons.
Question 2: Does recovery/ conservation depend on species-specific actions?
Response: Yes
Justification: Targeted survey of North Somerset and North Devon required to determine population sizes and ecological requirements. Welsh seed held in Millennium Seed Bank
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: May have declined in North Somerset and North Devon due to increase in scrub and rhododendron, opening up sites would probably help

Species Assessment

Current step on the Species Recovery Curve (SRC): 2. Biological status assessment exists
Recovery potential/expectation: Medium-high
National Monitoring Resource: Opportunistic - insufficient
Species Comments: few specialist hawkweed surveyors

Key Actions

Key Action 1

Proposed Action: Survey of North Somerset and North Devon sites to assess possible reasons for decline, and collect autecological data where still present (vegetation niche, management) to assess conservation requirements.

Action targets: 2. Biological status assessment exists

Action type: Status survey/review

Duration: 2 years

Scale of Implementation: ≤ 20 sites

High priority sites: North Somerset and North Devon

Comments: Could be coordinated with surveys in Wales

Key Action 2

Proposed Action: Promote awareness of the group amongst landowners, understanding of conservation requirements amongst conservation professionals and identification skills amongst field botanists e.g. via BSBI training resources and workshops

Action targets: 5. Remedial action identified

Action type: Advice & support

Duration: 3-5 years

Scale of Implementation: ≤ 100 sites

High priority sites:

Comments: generic action
