Criteria

Question 1: Does species need conservation or recovery in England?
Response: Yes
Justification: VU in GB & England.
Question 2: Does recovery/ conservation depend on species-specific actions?
Response: Yes
Justification: Currently known from 6 native sites, all receiving targeted conservation management
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): 7. Best approach adopted at appropriate scales
Recovery potential/expectation: Medium-high
National Monitoring Resource: Combination - insufficient
Species Comments: A (short-lived?) perennial of open humid grass heath, that relies on grazing / disturbance to ensure an abundance of mineral soil microsites for germination. Seed long-lived, so species has ability to respond well to conservation management, even in 'lost' sites.

Key Actions

Key Action 1

Proposed Action: Monitor all populations on a 1-3 year basis, recording numbers of plants & assessing condition of sites /suitability for L. urens.

Action targets: 3. National Monitoring Plan agreed and implemented

Action type: Status survey/review

Duration: >10 years

Scale of Implementation: ≤ 10 sites

High priority sites: All.

Comments: Population numbers fluctuate widely, largely relating to condition of site. Frequent monitoring will ensure that remedial action can be taken if trends indicate a declining population overall.

Key Action 2

Proposed Action: Maintain & expand (to maximum) suitable open grass-heath habitat at all extant sites, ensuring a appropriate management regime of grazing & mechanical disturbance.

Action targets: 7. Best approach adopted at appropriate scales

Action type: Habitat management

Duration: >10 years

Scale of Implementation: ≤ 10 sites

High priority sites: All.

Comments: Species responds positively to appropriate grazing/disturbance management & probably favours sites with some light poaching of sward & soils. However, in many sites, area suitable for L. urens significantly curtailed due to cover of secondary woodland: wherever appropriate the area available to species should be expanded.

Key Action 3

Proposed Action: Review status of lost locations for species, assessing options for restoring areas to open grass-heath or gladed woodland, ideally with extensive grazing by cattle/ponies. Undertake restorative management where possible. Consider (re)introductions to sites where appropriate.

Action targets: 7. Best approach adopted at appropriate scales

Action type: Habitat creation

Duration: 3-5 years

Scale of Implementation: ≤ 5 sites

High priority sites: Yarner Wood NNR. Kilmington / Shute Hill.

Comments: Species likely to reappear if precise location of old records known.
