Two research surveys were made to check the bryophyte species in the botanical garden: one investigation was started before the reconstruction took place and one after the works ended. Altogether 46 taxa (2 liverworts and 44 mosses) were recorded. Changes of the bryophyte species diversity (10 mosses disappeared and 5 new mosses appeared) were evidently connected with the garden reconstruction and consequently with changes of the habitats, respectively their destruction and creation of the new ones.

The aim of this study was to explore the bryophyte diversity in the garden of Mátrai Gyógyintézet Sanatorium. In the investigated area 65 bryophytes were found, 3 liverworts and 62 mosses. Some near threatened taxa according to the Hungarian Red List were detected in the territory: Brachythecium glareosum, Cirriphyllum piliferum, Orthotrichum pumilum, Rhynchostegiella tenella and Syntrichia latifolia. The recent record of Syntrichia latifolia is the second in the North Hungarian Mountains, and the first in Mátra Mountains.
