Short-haired bumblebee reintroduction project
The Short-haired bumblebee (Bombus subterraneus) is native to the UK and was once widespread across the south of England, occurring as far north as Humberside. Post-1950s its population distribution became isolated and patchy. Its decline was almost certainly the result of the loss of the species-rich grassland habitats on which it depends. It was last recorded near Dungeness in 1988 and was declared extinct in 2000.
The Short-haired bumblebee reintroduction project aims to reintroduce this lost species to the UK, raise awareness of bumblebee and flower meadow declines, increase resident rare bumblebee populations, and recreate and give advice on managing and maintaining flower-rich areas. The project has been running since 2009 and is working with farmers, conservation groups, smallholders and other landowners to create flower-rich habitat within the release area of Dungeness and Romney Marsh in Kent and East Sussex.
2019 marked 10 years of the project, and is the longest running project for the Trust. The precise reason for the species’ extinction isn’t known for sure, but decreasing areas of suitable habitat were thought to have played a major role. Creating much needed habitat is a key aim for the project. Today landowners and farmers are looking after 2,460 hectares and are receiving advise from the project.
Monitoring over the ten years of the project has shown that several species of rare bumblebees have increased as a result of the project’s interventions. On nature reserves, rare bumblebees have increased 8-fold with advice and planting, and away from reserves (where advice alone is more common), rare bees have increased threefold. A significant achievement in a short space of ten years.
The three rare bumblebee species most frequently encountered in the project area (Bombus muscorum, Bombus humilis, and Bombus ruderatus) all show a trend towards increased abundance on sites where the project has carried out habitat advice and planting. The nationally rare Ruderal bumblebee has increased most significantly, and Dungeness is now one of the best places in the country for the species as a result of the project’s work. All three rare bumblebee species have been recorded returning to areas where they had not been seen for up to 25 years.
