| Abstract: | The EDGG methodology of sampling multi-scale biodiversity in grasslands and other open habitats is widely applied and has proven to be a highly informative and effective way of recording high-quality data allowing for a multitude of different analyses. Based on our experiences with sampling, storing and analysing such data, here we propose three additions to the protocol: (1) We recommend to record also 1000-m² plots in addition to the hitherto seven standard grain sizes of 0.0001–100 m², as 1000 m² is a standard grain size in many international studies. (2) Recording species cover also for grain sizes larger than 10 m² (where hitherto only presence-absence was recorded) can be done efficiently by noting these values only for the additional species in the larger plot and for those that show a strong deviation from the average of the two 10-m² plots. (3) Finally, sampling biomass is valuable for analyses of the productivity/disturbance and of nutrient limitations. Both aspects can be covered by harvesting aboveground biomass in two random subplots of 20 cm x 20 cm (0.08 m² in total) and fractioning the material into necromass, living bryophytes and lichens, living herbs and living woody species. While Addition 2 hardly requires any additional time and thus should be implemented always, Additions 1 and 3 come with significant addition-al effort, which normally pays off, but suggests that in case of time limitations they might be restricted to a representative subset of plots in a study. |
