WolfgangSchmidtassociatedParty2013-01-17Since 1968 the experimental study site on old-field succession in the Experimental Botanical Garden of the University of Göttingen (Lower Saxony, Germany) offers continuous data on vegetation development on permanent plots. The 23 plots (125-200 m*m) cover a range of undisturbed sites since the beginning of the experiment or since 1983 differing in there initial treatment, to plots underlying a certain yearly treatment like different mowing intensities (with and without fertilizer treatment) or ploughing. Beside continuous species list and species coverage, soil chemical properties, harvested biomass analysis and seed bank analysis data are available.Please obtaion permission from data owner for download.Obtain permission from data set owner(s)Lower Saxony9.94979.949751.566751.56671969-04-01Higher plants (spermatophyta, pteridophyta), 300ClassspermatophytaClasspteridophytaWolfgangSchmidtInstitute of Silviculture and Forest Ecology of the Temperate Zones, University of Göttingen

For vegetation sampling the plots were each subdivided in 3-8 subplots. Vegetation releves, including records of the percentage cover of all vascular plants in the tree, shrub and herb layer were conducted once (undisturbed plots, 1988-2011, since trees have started to dominate) or twice per year (all plots from 1969-1987, ploughed or mowed plots 1969-2011). Further information can be checked in the references (see reference list).

attached_fileNot authorized to access resourceOther timeseries Continuous data of all plots are available from 1969-1993. Between 1994 to 2011 there are some gaps. Please see time-table (attachment). Starting in 2009, plots of I-III sites are recorded in one year while plots of IV-V sites are recorded in the following year (see time-table). yearly Data on the geographic distribution of the taxa are not included in the database, but can be added easily by the check of a common flora (e.g. Rothmaler). Data of ecological traits are not included in the database, but can be added easily by the check of a common flora or data base on ecological traits (e.g. Ellenberg et al. 2001 on life forms, leaf traits etc. or Kleyer 1995 - Biological Traits on Vascular Plants or The LEDA traitbase by Knevel et al. 2005, see also some of our publications). Climate data from the nearby weather station Göttingen are available from 1955 up to now. Land use data are also available (e.g. change in the environmental landscape from agricultural to urban ecosystems).
