There has been only one time-controlled study, in Canada, comparing the occurrence of bryophyte
species in forests regenerating after wildfire with that in those regenerating after logging and
regeneration burning. Previous work on vascular plants in Tasmanian tall open-forest dominated by
Eucalyptus showed that filmy ferns were less common in areas that had been logged and regeneration
burned than in areas burned by wildfire two decades after the events, which suggested that hygrophilous
species, such as bryophytes,might be vulnerable to this silvicultural system. Bryophytes, vascular plants
structural and environmental data were collected from 50 sites, which had been burned in wildfires or
clearfelled and burned by prescribed fires 31–39 years previously. Eighteen percent of the vascular plant
species for which it was possible to develop a multiple regression model had logging/wildfire as a
component, whereas the equivalent figure for bryophytes was 17%. The negative effects of logging were
concentrated on the more hygrophilous species, and the positive effects were concentrated on the basal
area of tree species and some of the mosses dependent on them. We conclude that wildfire and logging
followed by regeneration burning result in vegetation differences that last more than three decades after
disturbance, that these differences are nomore pronounced for bryophytes than for vascular plants, and
that hygrophilous taxa are favoured more by wildfire than logging.
