Justification for EICAT assessment
Predation by the Song Thrush caused the decline of the Lord Howe Flax Snail (Placostylus bivaricosus) and other snail species (Placostylus and Paryphanta). However, other causes for the decline are habitat destruction, habitat modification, predation by other introduced species and collection of live animals for their shells by humans may also once have had an effect (Parrish et al., 1995; Threatened Species Scientific Committee, 1999).
