Bryophyte distribution in blackwood forests of the Otway Ranges, Victoria

Tracheophyte and bryophyte distribution was surveyed in nineteen Blackwood-dominated sites of two different origins in the Otway Ranges. Nine sites were placed in sheltered gullies and ten sites were placed in upslope stands. Fifty-one tracheophyte taxa, 49 moss taxa and 39 liverwort (including hornwort) taxa were recorded in total. Bryophyte species richness was significantly higher in gully sites. The most frequent bryophyte taxa varied between gully and upslope sites. The percentage
occurrence of certain substrates was shown to be an important determinant of bryophyte species richness and composition. Decaying wood and soil supported the greatest number of bryophyte taxa compared with all other substrates.
