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.

本研究提供一套数据集，包含来自挪威华勒（Hvaler）市镇阿克勒亚（Akerøya）32处贝壳滩（shell-bed）的100个1平方米植被样方（vegetation plot）的物种多度数据，涉及106种维管植物（vascular plant）、36种苔藓植物（bryophyte）以及13种地衣（lichen）。该区域原属东福尔郡（Østfold），2022年起并入维肯郡（Viken）。所有样方均于1979年6月针对物种组成开展分析。本数据集为下述学术出版物提供了数据支撑：Halvorsen, R. 1980. 《挪威东南部华勒阿克勒亚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，奥斯陆出版。ISSN 0300-1156。
