The aim of the bachelor's thesis is to present the possibilities, significance and possible problems of ex-situ protection for the future conservation of biodiversity of plants on Earth. In the introductory part of the thesis, the individual processes and programs of ex situ protection are described, with the help of literature search. At the same time, information on international cooperation in the field of seed banks and botanical gardens is presented, which, through their activities and mutual cooperation, create rescue programs to secure as many samples of plant material for possible future use. The work also mentions international plant databases, which provide the accurate and detailed information about the preserved material of rare and endangered plant species for the public. Further in the thesis, the currently known problems of ex situ protection with their impacts on the collected and stored material are mapped.

The work is focused on identifying endangered species of Training Forest Enterprise Křtiny, which are grown by the locals on their land in selected communities. Study deals with legislative restrictions in the management of endangered plant species. It explains the concept of the term "non-wood forest products", and its relevance to the forestry and biodiversity. In the work described conducted a field survey in which was collected seeds of selected endangered in the Moravian Karst for school forest enterprise Křtiny. Seeds were sown in a cold frame of Botanical garden and arboretum of Mendel University in Brno and made them germination tests. The last section describes the idea of certifing some forest nursery in the area of the Moravian Karst, giving the logo "MORAVSKÝ KRAS regional product."
