Scope: Re-sampling of semi-permanent plots on arable fields (1950s/60s-2009) to analyse changes in species composition.
Abstract: The database aims at a comparison of arable plant vegetation in the 1950s/1960s and today. Historical vegetation samples were collected in 10 regions of Central and Northern Germany; three on loamy sides (122 relevés), four on sandy sites (154 relevés) and three on calcareous sites (116 relevés). New vegetation data were collected by S. Meyer, B. Krause and K. Wesche. Usually, c. 40 historical (field interior), c. 40 recent samples (field interior) and another c. 40 recent samples (field margin) are available, taken at approximately the same location.
