The historic market town of Gillingham in Dorset has become the first local authority in the UK to commit to a nationwide challenge aimed at reversing the severe decline in butterfly populations.
The Butterfly Conservation charity called on councils across the country to take action. Gillingham’s pledge includes five steps: improving and creating habitats for butterflies and moths, ending the use of pollinator-killing pesticides, ensuring access to green spaces within a 15-minute walk, and addressing light pollution.
Data released last year showed 2024 was one of the worst years on record for butterflies, with 31 of the 59 resident UK species in long-term decline. The small tortoiseshell has seen its numbers drop by 86 per cent since 1976.
Gillingham mayor Fiona Cullen said the decision was “an absolute no brainer” given the current climate and nature emergency. She noted that the town already implements many required actions, but light pollution is the “trickiest pledge” due to public safety concerns.
To tackle light pollution, Gillingham plans to create a ‘Moon Meadow’ – a green space away from artificial light, filled with plants beneficial for nocturnal pollinators like moths.
Pete Hughes from Butterfly Conservation said towns signing up could make “a real difference”, adding that within years they could start to see more butterflies. The charity hopes other towns will follow Gillingham’s lead.
