]. The plant underwent a catastrophic decline of almost 95% between 1946 and 1956. The population has now started to recover as a result of natural resistance in part of the remnant population and intensive conservation efforts. Some of the causes of reduction are not reversible due to urbanization and habitat loss, but provided that the recovery is maintained, future re-assessments should result in downlisting. The plant is currently classified as 'Critically Endangered' in the IUCN Red List of Threatened Species(2011)[

Juniperus bermudiana is grown as an ornamental and timber tree outside its native range. Perhaps the biggest planting is in St Helena and on Ascension Island where seed was introduced during the mid-19th century to establish timber tree plantations. Ironically, on these islands the tree is now becoming an invasive problem[
