The Valencia County Regional Administration (Spain) is developing a flora conservation programme which includes bryophytes, with the financial support of the European Union (Life Programme). Revised IUCN Red List catezories have been applied following the guidelincs proposed by Hallinbick & al (1998) and Girdenfors (1996). This Red Data List includes 50 taxa, 32 mosses and 18 liverworts. Threatened categories for Iberian Peninsula and Europe according to others authors and some annotations for each taxon are given. Moreover, two additional lists of those taxa evaluated as Lower Risk near threatened (LRnt) and Data Deficient (DD) are added. The most important species of this Red Data List are Riella helicophylla, R. cossoniana and R. notarisii since the Valencian populations constitute 2 high percentage of the European populations. Other species like Pottia pallida, Pterygoneurum lamellatum and P. subsesile, reported as vulnerable by other authors, are now in a new unthreatened status: Lower Risk, near threatened (LRnt).
