Amrum is a small barrier island on the north-west coast of Germany. The distribution of vascular plants was examined by surveying their 1km grid square occupancy across the whole island. These data were used in a study on the recent vegetation change in the island.

Data Records

The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 3,786 records.

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Geographic Coverage

Amrum is a small barrier island off the coast of Schleswig-Holstein, Germany. It covers an area of about 20 km , though considerable areas of saltmarsh vegetation are exposed at low tide. Amrum is approximately 10 km long and 3 km wide at its widest point. Its main habitats run in north-south bands along the island. In the west are open sand flats with a sparse fore-dune vegetation, moving eastward there is a complete dune succession ending in conifer plantations. Beyond the plantations is arable farmland and grazing. Along the eastern shore are mainly saltmarshes and mudflats. Other important habitats include freshwater ponds, marshes and ditches, heathland, urban area and the seawall.

Bounding Coordinates South West [54.6, 8.28], North East [54.72, 8.41]

Taxonomic Coverage

The study covers all vascular plants growing in the wild. Obviously cultivated plants were excluded, though trees planted for forestry were included as these form so much of the island's habitats.

Project Data

No Description available

Title A vascular plant survey of Amrum
Funding none
Design Description A survey to catalog all the plants of Amrum

The personnel involved in the project:

Quentin Groom
  • Principal Investigator

Sampling Methods

The biodiversity of each 1 km varies considerable so there was no set time limit for surveying a particular square. Grid squares were surveyed as intensively as considered necessary to find all but the rarest species. Aerial photographs, maps, previous surveys and local experts were all used to direct surveying to all potentially important habitats.

Study Extent The survey covered all vegetated areas of the island were access was permitted. In fact, this covers most of the island, however, some nesting bird colonies and private gardens are completely inaccessible.
Quality Control Some Salix specimens where identified by R.D. Meikle.
