Policy F4: Gulls


Development proposals are expected to implement all viable non-lethal humane steps to prevent gull roosting, nesting and damage should be taken. Gull mitigations measures shall be well designed and sympathetic to the building and its setting.

3.6.17 Both lesser black-backed gulls and herring gulls nest in and around Gloucester City. Both species are experiencing declines across their range and a major proportion of the European breeding population of both species is found within the UK. The herring gull's conservation status is listed as 'red' and that of the lesser black-backed gull 'amber'. Gulls are declining in their traditional breeding localities due to a reduction in food (fish) and have colonised urban areas because of the ready availability of food (food waste, litter) and predator-free nest sites (buildings).

3.6.18 Gloucester's large urban gull population cause disturbance and damage to buildings, through their excrement, nesting, and from their mating ritual of dropping stones on glazing and other shiny materials. They can be a nuisance to residents and visitors and can be particularly aggressive at certain times of the year.

3.6.19 All viable non-lethal steps should be taken in new development to prevent exacerbation of this problem. Gull mitigation measures should be considered from the outset to avoid the need for retro-fitted schemes which can be costly and disturb an established habitat. Applicants should also consider access arrangements for the maintenance of mitigation measures.

3.6.20 Advice on design advice and suitable non-lethal mitigation measures is available in 'Gulls - How to Stop Them Nesting on Your Roof' (2016), produced by Gloucester City Council, or any future iteration.
