Overview of the Conservation Effort
The pine hoverfly, a critically endangered insect species, has experienced a remarkable population rebound in Cairngorms National Park, Scotland. Conservationists report that the number of pine hoverflies could now exceed the human population in the area. Seven years ago, only about 50 individuals were believed to exist in a single woodland site. However, through a dedicated captive breeding program initiated in 2018, approximately 30,000 pine hoverflies have been released into the wild.
Key Players in the Initiative
The conservation effort is spearheaded by the Royal Zoological Society of Scotland (RZSS) in collaboration with the Pine Hoverfly Steering Group, the Rare Invertebrates in the Cairngorms (RIC) project, and local landowners. The RIC project is managed by NatureScot and receives support from the Scottish government's Nature Restoration Fund. This collaborative approach aims to protect and enhance habitats for threatened invertebrate species across the Cairngorms.
Breeding and Release Process
The breeding of pine hoverflies takes place at the RZSS Highland Wildlife Park in Kincraig, where conservationists utilize unconventional methods to simulate the flies' natural habitat. Larvae are raised in jam jars and hummus pots, where they are fed a "nutritious soup" made from a mixture of rainwater and pine wood chippings. The breeding area is carefully monitored for temperature, and damp moss is used to seal the jars, replicating the conditions necessary for the larvae's survival.
Since the program's inception, releases have occurred in several phases, including the introduction of approximately 7,000 larvae in March 2021 and an additional 3,000 in October of the same year. The success of these efforts was highlighted in 2022 when an adult pine hoverfly was spotted in the wild for the first time in a decade.
Importance of the Reintroduction
Georgina Lindsay, the RZSS field conservation manager, emphasized the significance of the reintroduction project, stating, "This milestone is emblematic of so much hard work and dedication, and a tribute to collaborative work." The project not only aims to restore the pine hoverfly population but also seeks to enhance the overall biodiversity of the Cairngorms National Park.
Future Directions
The RIC project continues to focus on identifying and protecting threatened invertebrate species, ensuring that the conservation efforts for the pine hoverfly and other species remain a priority in the region. As the population of pine hoverflies grows, conservationists remain vigilant in monitoring their habitat and health to secure a sustainable future for this rare insect.
