Abstract

Amrum is a small barrier island on the north-west coast of Germany. The distribution of vascular plants was examined by surveying their 1km2 grid square occupancy across the whole island. These data were used in a study on the recent vegetation change in the island. These data include 3786 observations of 450 taxa collected in two surveys in 2007 and 2008.

Highlights

Amrum is a small barrier island off the coast of Schleswig-Holstein, Germany
Amrum has been the subject of many botanical surveys and this survey continues that tradition (Christiansen 1961, Türk 1994, Petersen 2000, von Seemen 1899, Schiøtz 1860)
The grid is based upon the spatial reference system EPSG:31467 DHDN / Gauss-Kruger zone 3 (Fig. 1)

Summary

Introduction

Amrum is a small barrier island off the coast of Schleswig-Holstein, Germany. It covers an area of about 20 km2, though considerable areas of saltmarsh vegetation are exposed at low tide. Amrum is a small barrier island off the coast of Schleswig-Holstein, Germany. Its main habitats run in north-south bands along the island. These data were used in a study of change in the islands flora (Groom 2010). Study extent: The survey covered all vegetated areas of the island were access was permitted. Sampling description: The biodiversity of each 1 km2 varies considerable so there was no set time limit for surveying a particular square. Description: Amrum is one of the North Frisian Islands, Schleswig-Holstein, Germany.
