The plant population of the Botanic Garden at the Faculty of Biology is also part of the scientific collections of Johannes Gutenberg University Mainz. It comprises about 9,000 different plant species and varieties from almost all regions of the world, whose origin and collection data are precisely documented. The intake and transfer of plants is carried out in accordance with the Convention on Biological Diversity (CBD) and in strict compliance with the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). Through conservation cultures (ex situ) of endangered native wild plants, the Botanical Garden makes a valuable contribution to the preservation of biological diversity.
The Botanic Garden of the Johannes Gutenberg University Mainz was initially established in 1946 as a research and teaching garden by Prof. Dr. Wilhelm Troll. The garden area has a size of about 90,000 square meters and, in addition to the large outdoor area and the greenhouse area, also includes the Faculty of Biology in the courtyard of the old Faculty of Natural Sciences and the rock garden (Alpinum) at the entrance to Albert-Schweitzer-Straße. The main focus of the collections is the large arboretum, which is one of the most species-rich collections of woody plants in Germany, a near-natural replica of the Mainz sand flora, European steppe plants as well as the large systematic department, in which the plants are grouped according to family criteria based on molecular family trees. In the greenhouse area, special attention is paid to tropical crops.
The aim of the Botanic Garden is to contribute to the study and preservation of the earth's plant diversity. To this end, the garden and its collections support courses and research projects in the Faculty of Biology at Johannes Gutenberg University Mainz, as well as in other faculties, research and educational institutions. With the Green School, the garden is now heavily involved in educational work. The Botanic Garden is also a place of relaxation and leisure on the campus of Johannes Gutenberg University Mainz. Visitors are welcome!
