Criteria

Question 1: Does species need conservation or recovery in England?
Response: Yes
Justification: Eng WeBS trends (25 yr -1%, 10 yr -22%). Seabirds Count -60% since S2K (natural nests)
Question 2: Does recovery/ conservation depend on species-specific actions?
Response: Yes
Justification: Non breeding pop. Breeding pop data deficient. Priority to address breeding population.
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: priority to address breeding population

Key Actions

Key Action 1

Proposed Action: For natural sites, ensure optimum management of most important breeding sites including predation, biosecurity, disturbance, habitat management, assessment of marine infrastructure/collision risk, and supported by regular site monitoring to assess impacts and inform management. Consider and as appropriate implement the recommendations of the 2016 SPA Review for this species. Up to date evidence required for non-breeding populations.

Action targets: 7. Best approach adopted at appropriate scales

Action type: Habitat management

Duration: >10 years

Scale of Implementation: ≤ 50 sites

High priority sites:

Comments: benefits other priority species

Key Action 2

Proposed Action: Carry out regular monitoring of Herring Gull populations, including in urban areas, to inform assessment of national and regional trends via the Seabird Monitoring Programme.

Action targets: 7. Best approach adopted at appropriate scales

Action type: Targeted monitoring

Duration: >10 years

Scale of Implementation: National

High priority sites:

Comments: also relevant for other large gulls

Key Action 3

Proposed Action: Regularly review the impacts of licensed control of this species using an evidence based approach, whilst taking into account the effects of HPAI.

Action targets: 7. Best approach adopted at appropriate scales

Action type: Legal protection

Duration: >10 years

Scale of Implementation: Unknown

High priority sites:
