說明
We present a data set consisting of abundance data for 106 vascular plant species, 36 bryophyte species and 13 lichen species from 100 vegetation plots, each 1 m2, distributed on 32 shell-beds at Akerøya, Hvaler municipality, former Østfold (in 2022 Viken) county. The plots were analysed with respect to species composition in June 1979. These data formed the basis for the publication: Halvorsen, R. 1980. Numerical analysis and successional relationships of shell-bed vegetation at Akerøya, Hvaler, SE Norway. Norw. J. Bot. Vol. 27 pp. 71-95. Oslo. ISSN 0300-1156.

取樣方法
Species abundance values were obtained by visual assessment, using the Hult-Sernander-Du Rietz cover scale, published, e.g. in Du Rietz, G.E. 1921. Zur metodologischen Grundlage der modernen Pflanzensoziologie. Uppsala. The values of this five-grade ordinal scale are: Value | Percentage cover (%) 1 | present but <6.25% 2 | 6.25 - 12.5 3 | 12.5 - 25 4 | 25 - 50 5 | 50 - 100
| 研究範圍 | 100 vegetation plots (each 1 m2) from 32 shell-beds at Akerøya, Hvaler, SE Norway, during July 1979 |
