Abstract
Bryophyte diversity in tropical forests is closely related to elevation. A survey
was undertaken of the bryoflora of a poorly known cloud forest environment from 1,000
to 1,500 m.a.s. in Pico do Marumbi State Park, state of Paraná,Brazil. The aim was
to analyze the geographical range of the bryoflora and significance of this elevational
zone to bryophyte diversity. We found 364 bryophyte species, including 187 species
of mosses, 175 liverworts and two hornworts. This diversity represents 40% of the
bryoflora of Paraná and 24% of that of Brazil. Forty-one Brazilian endemic species
were found, representing a highly relevant feature for the preservation of the area.
These results emphasize the importance of Pico do Marumbi State Park to the conservation
of bryophyte diversity and to understanding the species of the state of Paraná, as
well as demonstrating the importance of bryophyte surveys in the Atlantic Forest of
Southeast Brazil.
