Criteria

Question 1: Does species need conservation or recovery in England?
Response: Yes
Justification: GB Red List (Fox et al. 2019): EN. Restricted to a small number of sites in and around the Lake District. Populations are vulnerable to lack of habitat management. Targeted monitoring (2000-2018) shows an increase in abundance; however, abundance appears to have declined in recent years.
Question 2: Does recovery/ conservation depend on species-specific actions?
Response: Yes
Justification: Requires bespoke management to benefit the single larval host plant, Touch-me-not Balsam.
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

Key Actions

Key Action 1

Proposed Action: Investigate and trial alternative management approaches to cattle grazing as cattle grazing is ceasing at some sites for the moth.

Action targets: 6. Recovery solutions trialled

Action type: Scientific research

Duration: 3-5 years

Scale of Implementation: ≤ 10 sites

High priority sites: Lancashire sites, possibly some Cumbria sites

Comments:

Key Action 2

Proposed Action: At sites which can be cattle-grazed, ensure appropriate winter grazing is carried out to encourage germination and spread of the foodplant.

Action targets: 7. Best approach adopted at appropriate scales

Action type: Habitat management

Duration: >10 years

Scale of Implementation: ≤ 10 sites

High priority sites: Lake District sites

Comments:

Key Action 3

Proposed Action: Assess factors causing decline in foodplant at known sites for the moth and reasons for other sites having stable populations of foodplant.

Action targets: 4. Autecology and pressures understood

Action type: Scientific research

Duration: 3-5 years

Scale of Implementation: ≤ 10 sites

High priority sites: Lake District sites
