Criteria

Question 1: Does species need conservation or recovery in England?
Response: Yes
Justification: Confined to two sites considered native in England (& Britain), with just a single plant at one site.
Question 2: Does recovery/ conservation depend on species-specific actions?
Response: Yes
Justification: A long-lived species, but only regenerates where damp bare sand exposed, either naturally or mechanically/artificially. The species has responded well to conservation management in Devon.
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): 2. Biological status assessment exists
Recovery potential/expectation: Medium-high
National Monitoring Resource: Combination - sufficient
Species Comments: A long-lived species of dune slacks in Devon & Somerset: currently abundant in southern half of Braunton Burrows but as a single individual at Berrow Dunes. Reproduces rapidly from seed on bare sand in seasonally-flooded dune slacks, & recent work at Braunton (through the Dynamic Dunescapes project to 2024), has resulted in major increase in population here

Key Actions

Key Action 1

Proposed Action: Review status of species in Britain (i.e. native or introduced), using criteria from Pearman & Preston etc - with full review of 2023 paper on status.

Action targets: 2. Biological status assessment exists

Action type: Scientific research

Duration: 1 year

Scale of Implementation: ≤ 5 sites

High priority sites: Berrow Dunes SSSI (Somerset) Braunton Burrows SSSI (Devon)

Comments:

Key Action 2

Proposed Action: Undertake careful turf paring / scraping at Berrow Dunes, to provide bare, seasonally-flooded sand/peat for seedling establishment

Action targets: 7. Best approach adopted at appropriate scales

Action type: Habitat management

Duration: 2 years

Scale of Implementation: 1 site

High priority sites: Berrow Dunes SSSI

Comments: Species has survived at Berrow Dunes as a single patch since discovery in 1896. The single clonal patch has spread from 15 inches (c. 1912) to 4 metres (2014), but increase from seed hindered by competition here.
