Nevertheless, existing monitoring programmes in Germany only cover the last two decades and lack data, coverage and integration. The project "sMon – Analysing trends in German species data" initiated by the German Centre for Integrative Biodiversity Research (iDiv) Halle-Jena-Leipzig has the aim to mobilize data from different sources to derive biodiversity trends. The data used comprise very different spatial and temporal grains, ranging from vegetation plot time series on a very few metres squared to grid cell mapping of whole Germany. The different types of data have a poor temporal or spatial coverage, but can provide important information on biodiversity change which goes beyond current programmes. The analysis at the coarse scale of 100km2-grid cells revealed losses in frequency of about 70% of all plant species in Germany. The spatial patterns in losses and gains differed between native species, archaeophytes and neophytes.Ute JandtDr. Institute of Biology, Geobotany and Botanical Garden, Martin Luther University Halle-Wittenberg, Halle, Germany.Work experience:2004-today: Senior researcher at the Institute of Biology / Geobotany and Botanical Garden, Martin Luther University Halle-Wittenberg, Halle, Germanywww.uni-halle.de/botanik Vascular plants, bryophytes, lichens, vegetation science, nature conservation and protection, vegetation databases, biodiversity research, community assembly Business or sector Research and Education: 2020-today: Senior researcher in EuropaBON, Monitoring ecosystems through research, innovation and technology 2012-today: Member of the German Centre for Integrative Biodiversity Research (iDiv)Education and training:1999: Doctoral degree in Ecology (Dr. rer. nat.), University of Göttingen 1991-1992: Diploma thesis in vegetation, University of Göttingen 1985-1991: Biology at the University of Göttingen 1984: Abitur Georg-Christoph-Lichtenberg-Gesamtschule in Göttingen
