Gravhøje som øer i agerlandet: Forandringer i floraen 1961 til 2000
(2003) In Flora og Fauna 109(3-4). p.95-100- Abstract
- A published investigation in 1961 of the vegetation on 10 burial mounds in southern Zealand was repeated in 2000. The burial mounds were situated as islands in the intensively used arable landscape. It is likely that such small fragments receive great inputs of Nitrogen by wet deposition and spill-over of artificial fertiliser from the surrounding fields. It was hypothesised that burial mounds in close contact with arable farming should show early signs of effects upon vegetation of eutrophication, and potentially warn of long-term changes in more coherent habitat areas of similar kind. We analysed the data by Detrended Correspondence Analysis (DCA), and compared the sample scores from the two surveys by pairwise t-tests. The DCA-axes were... (More)

We analysed the data by Detrended Correspondence Analysis (DCA), and compared the sample scores from the two surveys by pairwise t-tests. The DCA-axes were interpreted in terms of measured and calibrated environmental parameters, soil
pH, soil type, cover of woody plants, and calibrated Ellenberg N-value. It was found that a significant change in the species composition had taken place. Nitrophilic and shade-tolerant species had increased significantly. Common species typical of dry grassland and heathland had decreased in abundance, and rarer species had disappeared altogether. The vegetation changes are discussed in terms of changed agricultural land-use and ceased grazing. (Less)
