Adiantum Bellum -

: Primary dangers include habitat fragmentation due to residential and tourism development, which destroys the specific cave-mouth and rocky woodland environments it requires. Invasive species like Cyrtomium falcatum (Holly Fern) also compete for its limited ecological space.

: Its native range is strictly limited to the Bermuda archipelago. It is one of the few indigenous pteridophytes on the islands and has not naturally established populations elsewhere. adiantum bellum

The Bermuda Maidenhair Fern is a , meaning it is evolutionarily specialized to grow on rocks rather than in soil. : Primary dangers include habitat fragmentation due to

: For those interested in cultivation, it requires conditions mimicking its subtropical home. It thrives in high humidity and bright, indirect light, making it a popular indoor or greenhouse plant in cooler climates. It is hardy only in USDA zones 9 and above and must be protected from frost. It is one of the few indigenous pteridophytes

As of 2017, the IUCN Red List assessed Adiantum bellum as . However, its long-term survival is inextricably tied to habitat protection.

: The plant exhibits significant variation in size; specimens growing in ideal soil and moisture can grow significantly larger than those in harsher rock crevices, a trait previously leading botanists to misclassify larger variants as a distinct variety called walsingense .
