ReSurveyEurope

ReSurveyEurope Initative - EVA call for data contribution and collaboration [PDF]

ReSurveyEurope aims at mobilizing vegetation-plot resurvey data with repeated measurements over time and establishing a collaborative initiative as a basis for nuanced and robust assessment of biodiversity trends on small spatial grains over longer periods in Europe. Our initiative aims at inclusion of time series with repeated sampling of the same plot in the European Vegetation Archive (EVA, http://euroveg.org/eva-database) or identifying such samples in the existing EVA databases if they are already included. It also supports a parallel initiative within the global vegetation database sPlot (starting with its next version 4.0). While the ReSurveyEurope within EVA focuses on Europe, sPlot will collect such time series outside Europe and seek the consent of the EVA contributors to combine the data at the global scale, following the sPlot rules.

ReSurveyEurope initiators

Idoia Biurrun (ES), Helge Bruelheide (DE), Milan Chytrý (CZ), Stefan Dullinger (AT), Franz Essl (AT), Stephan Hennekens (NL), Ute Jandt (DE), Florian Jansen (DE), Borja Jiménez-Alfaro (ES), Ilona Knollová (CZ), Anna Kuzemko (UA), Bernd Lenzner (AT) and Francesco Maria Sabatini (DE)

Contact – conceptual issues

Contact – data management issues

The ReSurveyEurope initiave has been proposed:

  • To establish a network of scientists that collaborate in collecting and analyzing fine-scale plant community resurvey data (relevés, plots) from Europe. The approach shall be inclusive and transparent, and thus ReSurveyEurope will be modelled according to the rules of the European Vegetation Archive (EVA).
  • The focus of ReSurveyEurope will be put on regions, habitat types and ecosystems that are less covered by other initiatives, in particular open habitats such as grasslands, fields and wetlands, especially in lowlands and at mid-elevations. However, in principle, ReSurveyEurope will be collecting data from all ecosystems all over Europe.

Collaboration, governance and decision making

Such a collaborative initiative depends on the willingness of many actors to collaborate, and thus transparent governance and decision-making structures are essential. ReSurveyEurope will thus follow an inclusive approach in terms of open collaboration and co-authorship policy, which builds on the experiences and approach of EVA (see co-authorship arrangements at Data Request Form). This implies that i) data owners/contributors will have to be asked for their approval for any specific analysis (allowing to opt-in for the resulting papers according to specific criteria such as the numbers of plots used in the analysis), and that ii) colleagues not directly involved in ReSurveyEurope can submit proposals for analyses which will be subject to approval. This approach will follow the EVA Data Property and Governance Rules (EVA Data Property and Governance Rules).

Data for ReSurveyEurope

The following data are suitable for ReSurveyEurope: fine-grain biodiversity data (e.g. relevés, plots, transects) that have sampled the presence (and ideally also abundance) of vascular plants with at least two repeated sampling events in different years done with identical or at least similar and comparable methods. This data call includes both the terrestrial and aquatic environments. The geographic scope is Europe.

    Data sets should contain as a minimum requirement:
  • a full compilation of vascular plant occurrences (presences/absences), preferably also information on abundance or proxies for abundance such as cover or biomass
  • plots’ latitude and longitude and information on the precision of the coordinates
  • sampling date (ideally the precise date, minimum the year)
  • plot size

Further, information on the method of data collection, vegetation cover, elevation, inclination, orientation, bedrock substrate, land use, recent land-use change and vegetation or habitat type would be most helpful.

Data provision format

The format of data provision should be ideally in Turboveg 2, in which the following header-data fields are added and filled in. Using Turboveg v. 2.148 or higher versions, a database structure with these fields can be downloaded from https://www.synbiosys.alterra.nl/turboveg/ under Database dictionaries / ReSurvey)

If the resurveyed plots are contained in an existing EVA database, indicate them in ReSurvey header data fields, and send the updated version of the database to EVA to Ilona Knollová.

If you have or obtain data from resurveyed plots that are not stored in any EVA database, you can either store them in an existing EVA database or send them separately to Ilona Knollová. If they are not included in any existing EVA database, we will store them in the new specialized EVA database called ReSurveyEurope. If you have many records from resurveyed plots (several hundreds or thousands), you can register them as a new EVA database. In such a case, please register this database also in the Global Index of Vegetation-plot Databases (GIVD; https://www.givd.info).

If your data are not in Turboveg or you do not use this program, please send it to us in any format. We will transform them into the Turboveg format.

Metadata

Each resurvey dataset should come with a brief metadata sheet. If one database contains data from several resurvey projects, each of them should be accompanied by a metadata sheet. Please use the downloadable metadata sheet provided at http://euroveg.org/download/ReSurveyEurope-Project-Metadata-Form.docx

Time line

Please send the data to Ilona Knollová (EVA Data Manager, ikuzel@sci.muni.cz) by 31/01/2021.

The aim is to have the first set of core data collated by 30/03/2021.

We plan to write a short overview paper introducing ReSurveyEurope, its current status and future opportunities for a scientific journal (in 2021). This paper will present the idea, status quo and outline next steps. All data contributors will be invited for co-authorship.

After this paper is published, ReSurveyEurope will be used for various analyses, for which data contributors can opt-in as active co-authors.

For any queries, pls send e-mails to the contact persons.
