sPlot Meetings and Workshops


The sPlot project is developed and guided by two types of meetings: the workshops and the ordinary meetings.

The workshops are immersive experiences in which a group of scientists get together for a couple of days talking about ideas for the development of the consortium as well as doing research with sPlot data.

The ordinary meetings are those when members of the consortium reunite for a short meeting lead by the sPlot core team, composed by the sPlot coordinator and the Steering Committee. In these meetings members have a an update on the project, suggest improvements for its development, discuss resarch ideas and start new collaborative efforts.


The goals and guidelines of the sPlot Consortium were established in a first workshop in 2013 and further developed in two subsequent ones in 2014 and 2016 at the iDiv headquarters in Leipzig, Germany.

Workshop I

From 6th to 9th March 2013, 42 researchers comprising representatives of large plot and trait databases, specialists in plant community ecology, macroecology and global change ecology as well as experts in biodiversity informatics and advanced statistical methods gathered in Leipzig. During four intensive days, they discussed analytical approaches, defined requirements for data to be used in the analyses, planned the coming activities and last but not least coined “sPlot” as acronym for the sDiv working group.

Workshop II

When a reasonable data coverage across the world’s biomes was achieved (sPlot 1.0 with 840,000 plots), we organised the second Meeting from 2nd to 5th December 2014 at the iDiv headquarters in Leipzig, Germany. 28 scientists from nine countries and four continents used this test version of sPlot and its intersection with the TRY trait database to develop and test promising analytical approaches and to draft outlines of the first series of sPlot publications, planned for 2015.

Workshop III

Plant trait-environment relationships, biodiversity and invasion patterns across the world's biomes

The sPlot III workshop took place at the iDiv headquarters in Leipzig, Germany, from 24th to 28th October 2016.

The sDiv project sPlot originally was aimed at analysing the plant trait-environment relationships across the world’s biomes. After two workshops (March 2013, December 2014) and with the recent release of the sPlot 2.0 database in January 2016 we still pursue this original aim but have widened our scope based on the unique data source we created. sPlot 2.0 contains >1.1 million vegetation plots from 130 countries and all seven continents plus a taxonomic backbone that has been successfully matched with a gap-filled version of the global plant trait database TRY for 18 major functional traits. The small-grained, geo-referenced co-occurrence data at the global extent, in combination with the available trait data, opens new avenues for addressing fundamental questions of functional biogeography, community assembly, diversity patterns, invasion biology and macroecology.

During the sPlot workshop III (and the pre-workshop one week earlier), the working group finally made the database fit for the first series of analyses by removing last inconsistencies in the content, such as some errors in coordinates, cleaning species data (including separation of non-vascular plants), harmonizing and completing header data information (such as formation and degree of naturalness) and adding a series of standardised header data (climate, soil, assignment to a new 10-biome classification, biogeographic realm). This resulted in the now available sPlot 2.1, comprising 1,121,244 plots, which can be analysed together or separately for biomes or forests vs. grasslands, to name just a few of the readily implemented options.

The main part of the workshop was then devoted to advancing six paper projects. The 19 participants from seven countries and three continents worked in outbreak group to refine the theoretical frameworks and methodological approaches for these, carried out already large parts of the analyses, discussed the outlines of the manuscripts and started writing them up. These first papers thus likely will become ready for submission within few months. Their topics are: (a) a data paper, describing the content and the opportunities of the sPlot 2.1 database; (b) a methodological paper, presenting a sub-sampling approach that allows to gain more balanced subsets of plots out of sPlot that overcome spatially unequal sampling intensity; (c) a study that relates community-weighted means and variances of plant functional traits to macroclimatic drivers globally; (d) a study that quantifies how trait diversity is influenced by short-, medium- and long-term climatic variability; (e) a study aiming at quantifying how similar/dissimilar successful invaders are from their recipient community (and other, less successful aliens) in terms of traits and phylogenetic position; and (f) an analysis how communities of different composition/diversity varied in their productivity responses to extreme events (in terms of very low or very high precipitation) in recent decades.

During the last day, responsibilities and schedules for finalisation of all these papers were agreed upon. Moreover, we discussed about one dozen additional paper ideas that had originated shortly before or during the workshop. We solved several organisational issues of the sPlot Consortium and finally defined priorities and requirements for the expansion of the sPlot database towards the release 3.0, planned for the second half of 2017. Three and a half years after the initiation of the sPlot working group and at the end of five intensive days, the participants all felt that now everything is nicely in place and we can expect a first series of great papers to be submitted in the near future, that then will give rise to many more ideas for which the iDiv platform sPlot can provide a novel data source of unprecedented quality.


Ordinary meetings

1st ordinary meeting - 2022

Madrid, Spain

sPlot members got together for an ordinary meeting on 30th June 2022  during the 64th Annual Symposium of the International Society for Vegetation Science, held in Madrid, Spain. After two years of reduced contacts due to the COVID pandemics, it was a great opportunity for discussion of new ideas for the sPlot project.
