This chapter assesses forms of dispersal and describes some indications of potential dispersal limitation on island incidence in Barkley Sound. Ferns appear to be the classic plant taxon in which there are no dispersal limitations. The chapter analyzes fern distribution and the influence of habitat and suitable conditions for persistence, and also discusses various means of seed dispersal, including zoochory (dispersal via fruits or berries by vertebrates); hydrochory (dispersal by sea currents); and anemochory (dispersal by drifting in wind currents).

Keywords: dispersal; incidence; Barkley Sound; ferns; seed dispersal; zoochory; hydrochory; anemochory
