Appendix 1. Occurrences of the most important species on 30 islands in Hjälmaren over the century of succession. The list includes all species which have appeared on at least 10 of the islands or which have been noted as "abundant" on at least 3 islands in at least one survey. "Arrive" and "Decline" is the first and last survey at which the species reached at least 50% of its maximum island frequency, respectively (or abundance for species that were noted as abundant on at least three islands).
