Criteria

Question 1: Does species need conservation or recovery in England?
Response: Yes
Justification: GB Red List (Fox et al. 2019): NT. Highly restricted distribution in Norfolk Broads and Suffolk coast.
Question 2: Does recovery/ conservation depend on species-specific actions?
Response: Yes
Justification: An inhabitant of the drier parts of reed beds which could be adversely affected by management for other reed bed species and by rising sea levels.
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: Requires a particular stage of reed bed succession. Untargeted management is more likely to be harmful than beneficial.

Species Assessment

Current step on the Species Recovery Curve (SRC): 4. Autecology and pressures understood
Recovery potential/expectation: Low - Combination or other (detail in comments)
National Monitoring Resource: Opportunistic - insufficient
Species Comments: Low recovery potential due to a combination of limited reed beds that could be colonised and threat to low-lying sites from sea-level rise.

Key Actions

Key Action 1

Proposed Action: Fenn's Wainscot requires the drier parts of reedbeds. Ensure that management at occupied sites for species requiring wetter conditions , does not eliminate habitat for this species.

Action targets: 7. Best approach adopted at appropriate scales

Action type: Habitat management

Duration: >10 years

Scale of Implementation: National

High priority sites:

Comments:

Key Action 2

Proposed Action: Prevent conversion of drier parts of reed beds to woodland and/or restore areas where this has already occurred.

Action targets: 7. Best approach adopted at appropriate scales

Action type: Habitat management

Duration: 3-5 years

Scale of Implementation: National
