Bats are being prepared for battle: rare animal species are now inhabiting the ceilings of old bunkers.

In the tranquil corners of Dorset, a unique wildlife rescue program has transformed relics from wartime into sanctuaries for some of the rarest bats in the UK. The National Trust, in collaboration with the Dorset Bat Group, has implemented a project to protect these nocturnal creatures by converting World War II bunkers into human-proof fortresses, as reported by BBC.

Fort Henry, a historic structure from the 1940s, now serves as a refuge for five different species of bats, including the elusive greater horseshoe bat. To alleviate their concerns about the intrusion of intimidating bipeds, specially designed metal grilles have been installed in their new home. These grilles allow bats to come and go freely while preventing human access.

Ecologist Michelle Brown has enthusiastically embraced this initiative, highlighting the importance of providing safe roosting sites for these rare and fragile species. The choice of protected bunkers is of strategic significance for the comfort of these creatures. Bats require a cool, moist environment with stable temperatures—conditions that these concrete structures naturally provide.

In addition to Fort Henry, similar measures have been taken at the Godlingston Heath bunkers in Studland, further expanding the network of protected habitats for wildlife. Among the species benefiting from this initiative are the common pipistrelle, soprano pipistrelle, brown long-eared bat, and a yet-to-be-identified visitor—the whiskered bat.

The greater horseshoe bat is one of the largest bat species in the UK, with a wingspan of up to 40 centimeters. Despite their size, they are incredibly gentle creatures that play a significant role in controlling insect populations.

Unfortunately, over the last century, the population of the greater horseshoe bat has significantly declined, making such conservation efforts critically important. Colin Morris, affectionately known as the "bat man" in Blandford, designed and installed the most basic protection for their new habitats—the protective grilles. He reported the project's success, noting that shortly after their installation, five species of bats were discovered in the bunkers.

A key factor in the success of this initiative is the adaptability of conservation strategies and innovative approaches to addressing critical issues, transforming historical abandoned military sites into genuine havens for wildlife. By preserving these bunkers, the project not only safeguards a part of history but also contributes to the protection of bat populations threatened by habitat loss and other ecological challenges. Now, where people once planned to shelter from the horrors of war, these small, unusual creatures have found a quiet refuge, far from the troubles that humanity has brought upon them.
