Together with Dr. Sylwia Nowak, he presented the results of classifying the grassland vegetation of the Opole area using classical and molecular methods. This work was prepared in the Powsinski research team with significant participation of Dr. Anna Rucińska and Dr. Sebastian Swierszcz. The conclusions of the research were described by the session leader as "shocking" to everyone. They change the perception of vegetation typology and most other botanical studies in a fundamental way, showing that using standard observational methods we see only about 75% of the entire vegetation diversity.
