Bryophytes as small-sized plants are usually neglected by conservation efforts. The number of regional IUCN Red lists for bryophytes is also low compared to vascular plants. There is an increasing awareness that the vast majority of extinctions go unnoticed because they occur within small, highly neglected organisms despite representing the highest proportion of currently described species (Cardoso et al., 2011).
In her recent paper, Juana González-Mancebo (Moveclim Partner) and co-authors discussed the application of IUCN criteria to bryophytes in small and highly environmental diverse island systems and reported the first Red List for bryophytes of the Canaries which comprises 105 species. They concluded that the priority conservation should be given to freshwater habitats and cloud forests because both environments together contain 63 % of the endangered (EN) bryophytes in the Canaries.
Claudine Ah-Peng (Moveclim co-coordinator) and co-authors provided early this year the first IUCN Red List for Réunion (Mascarenes) liverworts and hornworts, 39 taxa of liverworts are threatened of near threatened with one species considered as regionally extinct. In Réunion, the threats that the bryoflora encounters are mainly due to human population growth leading to urbanization, habitat degradation, destruction and loss, clearing of native forest for cattle farming in the uplands and more recently moss harvesting for horticultural purposes.
