Summary of beach-cast Durvillaea sampling at four southern New Zealand beaches following April and July 2017 storm events. To avoid beach-cast material of local origin, sampling was restricted to specimens covered in L. australis barnacles. Sample sizes, numbers of specimens genetically assigned to each species/clade and mean (maximum) capitulum length of associated L. australis goose barnacles are indicated.
