We present a first survey of bryophytes in the LTSER-sites in Matsch/Mazia Valley. We examined five habitat types: dry grassland, fertilized meadow, larch forest, Swiss stone pine forest and one stream. Bryophyte species were recorded within 22 plots located between 1000 and 2300 m a.s.l. In total 95 taxa were found. The species assemblage comprised generalists as well as habitat specialists and is suitable for detecting habitat changes.
