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.

本数据集涵盖来自东南挪威原东福尔郡（2022年并入维肯郡）瓦勒尔市阿克勒岛32处贝壳滩的100个1平方米植被样方的物种多度数据，涉及106种维管植物（vascular plant）、36种苔藓植物（bryophyte）及13种地衣（lichen）。该批样方于1979年6月完成物种组成调查与分析。本数据集为下述学术出版物的核心基础数据：Halvorsen, R. 1980. 《挪威东南部瓦勒尔市阿克勒岛贝壳滩植被的数值分析与演替关系》，《挪威植物学杂志》（Norw. J. Bot.），第27卷，第71-95页，奥斯陆，ISSN 0300-1156。
