Red list reveals Britain’s extinction-threatened mosses and liverworts

Habitat loss blamed as study finds 19% of bryophyte species at risk and at least four have become extinct in Great Britain

Almost one-fifth of bryophytes – the plant group that includes mosses, liverworts and hornworts – in Great Britain are threatened with extinction, according to a new red list assessing their conservation status.

The red list, published in the Journal of Bryology, was compiled based on criteria and categories set by the International Union for Conservation of Nature.
