Botanical and mycological research

The research of the Botany Department is centred on current topics in the ecology, systematics, and evolutionary biology of plants and fungi (including lichens). We study the origins and drivers of current diversity of organisms and species communities, how they change over time, and which biotic and abiotic environmental factors are involved in these processes. In this approach, intersections with all other research departments of the SMNS arise and thus we collaborate with them within the framework of the research initiative.

A spatial focus of our work is Baden-Württemberg. For our research we use data from our extensive herbarium collection with about 1 million specimens, but also conduct field studies, such as the Floristic Mapping of Baden-Württemberg, a long-term Citizen Science project. State-of-the-art molecular and statistical methods, complemented by classical ecological experiments and field botanical studies help us to answer our research questions.

Working groups / Citizen Science

Since 1970, the flora of Baden-Württemberg has been systematically mapped over the entire area of the state. The first round ran until 1998. Currently, about 150 volunteers are mapping all wild plant species on the basis of quarter Messtischblätter (1:25 000 topographic maps) in a second mapping round. The distribution of the species is displayed on digital maps and continuously updated. Currently, more than 3.1 million data sets are available. The data are used for current research on floristic change as well as for the compilation of red lists and species protection programs. The second round of floristic mapping in Baden-Württemberg will end by the end of 2023. Since land use and climate change are leading to rapid, and in some cases profound changes in the flora, the third round of mapping will start in 2024.
