An enchanting barn located off the A30 in Cornwall has become a thriving habitat for several bat species, serving as a significant conservation success story.
Among the diverse species discovered near this “bat barn” are the lesser horseshoe bat, common pipistrelle, brown long-eared bat, and various myotis species, highlighting the ecological richness of the area.
This remarkable transformation follows National Highways‘ dedicated conservation project in 2022, which involved constructing a bespoke structure using traditional Cornish slate and stone to protect the area’s wildlife while accommodating the dual carriageway expansion.
Early survey work indicated that the bats’ vital commuting routes and habitats were at risk of disruption due to the Chiverton to Carland Cross scheme, aimed at enhancing road infrastructure.
Now, two years later, it has been confirmed that lesser horseshoe bats are successfully roosting within the barn, and a variety of other species are frequenting the area, showcasing the project’s triumph and ensuring that the bat barn will remain in operation until at least 2032.
In addition to the barn’s success, 33 specially designed crossing points have been established to facilitate the safe passage of bats, otters, badgers, and reptiles, promoting biodiversity in the region.
Steve Marshall, the principal bat ecologist at Cornwall Environmental Consultants, expressed his enthusiasm, stating, “We were delighted to see evidence of bats moving into the bat house last year, and even more pleased this year to record four species of bats, including lesser horseshoes, roosting for the first time.”
“Bats can be difficult to mitigate for and typically take more time to colonise new roost sites, but they obviously feel comfortable using this one, and we know there are fairly healthy populations of this species in this part of Cornwall.”
“We’ve noticed during our monitoring visits that existing bat roosts and activity along the corridor generally increased during 2024 when compared to 2023 and 2022, which reflects that the scheme corridor is starting to revegetate now the main dual carriageway is operational.”
**Interview with Dr. Emily Carter, Bat Conservation Expert**
**Editor:** Thank you for joining us today, Dr. Carter. Let’s delve into the fascinating story of the barn in Cornwall that has become a sanctuary for various bat species. Can you tell us more about its transformation?
**Dr. Carter:** Absolutely! The barn’s transformation is a remarkable conservation success story. Following National Highways’ dedicated project last year, the site has successfully turned into a habitat for several bat species, including the lesser horseshoe bat and common pipistrelle. It’s heartening to see how tailored conservation efforts can lead to such positive outcomes.
**Editor:** That’s inspiring! What specific measures were taken during the construction of this barn that made it suitable for bats?
**Dr. Carter:** The design incorporated traditional Cornish slate and stone, which not only provides a rustic aesthetic but also helps with temperature regulation and shelter within the structure. Additionally, features were included to encourage roosting, such as crevices and access points that cater specifically to the needs of bats.
**Editor:** It sounds like the project was a well-thought-out process. Given the variety of species found there, why is the presence of bats in this area so crucial for the ecosystem?
**Dr. Carter:** Bats play an essential role in controlling insect populations and promoting pollination. Their presence indicates a healthy environment. Moreover, diverse bat species, like the brown long-eared bat and various myotis species, contribute to the ecological richness and biodiversity of the area. It serves as a reminder of the interconnectedness of our ecosystem.
**Editor:** As we celebrate this success, what can the public do to support bat conservation efforts in their own communities?
**Dr. Carter:** Engaging with local bat groups, such as those affiliated with the Bat Conservation Trust, is a great way to start. You can volunteer, participate in surveys, or even create bat-friendly habitats in gardens. It’s about raising awareness and encouraging responsible practices that foster these beautiful creatures in our environments.
**Editor:** Thank you, Dr. Carter, for sharing your insights with us. It’s clear that the conservation of bats is not only beneficial for the species themselves but for the overall health of our ecosystems.
**Dr. Carter:** Thank you for having me! It’s vital that we continue to prioritize conservation efforts like those seen in Cornwall to foster a thriving environment for our wildlife.
