Description
Occurrence dataset created by emeritus Associate Professor Peter Vestergaard and published by Department of Biology, University of Copenhagen. In Danish waters, a gradient in seawater salinity between the brackish Baltic Sea and the salt North Sea exists. Along protected, low-energy parts of the adjacent coasts, coastal meadows (salt marshes), influenced by seawater of varying salinity, is a common type of nature. During the 1980s, the vegetation ecology of these salt and brackish coastal meadows was studied in the southeastern part of Denmark by Peter Vestergaard. For the study, 20 localities (loc. 1-20) were selected. The field work was carried out 1982-1985. In each locality, a number of compartments, each with a uniform plant cover, were selected and mapped. In total, 262 compartments (comp.1-262) were studied. The abundance of each species was estimated according to a 1-7 ordinal scale of cover-abundance. The dataset contains URLs for online images of maps with localities and selected examples of the habitats studied.

Méthodes d'échantillonnage
In each compartment 1) species composition was recorded, using a 1-7 ordinal scale of cover-abundance (http://digit.snm.ku.dk/DanBIF/DKCoastalMeadows/CoverageAbundanceScaleRef.jpg), for later multivariate analysis, 2) elevation was levelled in relation to mean water level, 3) soil samples were taken for later analysis of physical and chemical soil factors, 4) Human utilization was observed and later investigated in more details by interviews with present and former landowners, 5) a photo was taken, 6) GPS coordinates were later obtained using Google Earth.
