Degradation, destruction and extinction of the natural habitats are very common and frequent throughout the world. This process decreases the diversity of cryptogamic plants as well. However, their conservation was neglected for a long time. In 1990 both the IUCN and the IAB appointed committees to manage the conservation problems of bryophytes, and via public education to direct the attention to their important role in ecosystems.

In the Hungarian Red Data Book a red list of 120 bryophytes was published in 1990. It was a remarkably early initiative at European scale. The Red Data Book of European Bryophytes was published in 1995 by the European Council for the Conservation of Bryophytes. There are 47 bryophyte species in this book occurring also in Hungary. From these 47 species 3 are actually endangered, 13 potentially endangered, the others are rare or insufficiently known. The large proportion of the latter two categories also emphasizes the importance of the proposed investigations.

To eliminate the vast surplus of data, and to fulfil the requirements of the international and Hungarian nature conservation a database of the rare and endangered bryophytes was set up. Our main tasks in this project:

- revision and computerized data management of the collection records (Budapest, Hungarian Natural History Museum on other Hungarian herbaria, e.g. Debrecen, Eger, Szeged, Szombathely, Zirc),

- computerized data management of literature records,

and by chance:

- checking of the old records,

- finding new records.

It is very important to establish a reference collection of the rare and endangered species in BP, via collecting the missing voucher specimens at the known localities or exchanging duplicates by local herbaria. All of these are indispensable necessary for compiling a new bryophyte red list considering the IUCN recommendations and categories. The database as well as the reference collection play essential role in the future biodiversity research.

At first the distribution data of 47 species of the Red Data Book of European Bryophytes, which also occur in Hungary, were started to incorporate into the database. Next year this work will be continued with other rare species recommended to be protected in Hungary. By the help of the database it is possible to produce distribution maps for each species, and it is also possible to find regions or areas rich in species which have outstanding importance regarding the conservation of bryophytes. From the database some species of different distribution or importance and some important bryophyte habitats are presented.
