Presence data for vascular plant, bryophyte and lichen species in 100 vegetation plots (each 1 m2) from 32 shell-beds at Akerøya, Hvaler, SE Norway

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.

本研究所呈现的数据集包含来自100个植被样地、每个样地面积为1平方米的106种维管植物、36种苔藓植物及13种地衣植物的丰度数据。这些样地分布于挪威哈瓦尔郡阿克洛亚岛的32个贝壳床区域，该地区曾属奥斯陆省（2022年改属维肯省）。样地内的物种组成分析于1979年6月进行。上述数据构成以下出版物的基础：Halvorsen, R. 1980. 贝壳床植被在阿克洛亚，哈瓦尔，东南挪威的数值分析和演替关系。挪威植物学杂志，第27卷，第71-95页。奥斯陆。ISSN 0300-1156。
