Appendix B. A table showing shift in plant species composition in the low salt marsh exclosures.
TABLE B1. Increase and decrease of plant species in change of percentage cover between 1995 and 2001 on the low salt marsh (SE in parentheses), for each treatment on different-aged salt marshes. Plant species with more than 1% cover in the vegetation are shown and are grouped to the successional stage where they occur most. Treatments belonging to one experimental block are indicated by numbers (control 1, goose 1 and full 1 belong to one block). Significant differences between treatments within each block are indicated by different letters (P < 0.05, Tukey tests).
