Spatio-temporal variations in the application of the Braun-Blanquet approach in Europe
2018
An historical overview on the affirmation of the phytosociological method in Europe is presented. Some methodological and procedural differences in the application of the Braun-Blanquet approach, from the selection of the sampling plots to the assignment of relevés to existing or newly described units, are briefly commented. The main advantages and limitations of the phytosociological vegetation classification are reviewed and discussed, also in the light of their applications for vegetation mapping and monitoring.
Assessing plant diversity and composition in grasslands across spatial scales: the standardised EDGG sampling methodology
2016
This paper presents the details of the EDGG sampling methodology and its underlying rationales. The methodology has been applied during EDGG Research Expeditions and EDGG Field Workshops since 2009, and has been subsequently adopted by various other researchers. The core of the sampling are the EDGG Biodiversity Plots, which are 100‐m2 squares comprising, in two opposite corners, nested‐plot series of 0.0001, 0.001, 0.01, 0.1, 1 and 10 m2 square plots, in which all terricolous vascular plants, bryophytes and lichens are recorded using the shoot presence method. In the 10‐m2 plots, species cover is also estimated as a percentage and various environmental and structural parameters are recorde…
