Patterns and mechanisms of early plant primary succession on the pumice plain.

Primary colonists and mechanisms of their arrival to the pumice plain have been monitored since 1986. Measurements of seed rain have shown that the most common wind dispersed species arriving on the pumice plain are Anaphalis margaritacea, Epilobium angustifolium, and E. watsonii.
