Excursion to the Botanical Garden of TU Dresden

As a part of the programme of the 71st UNEP/UNESCO/BMUB International Short Course on Ecosystem Management – Biodiversity Conservation and Ecosystem Services, our diverse group from 21 countries (mainly from the tropics and subtropical areas) had the experience to visit an important place for tourists, scientists and environmentalists alike: The Botanical Garden of TU Dresden. With an extension of three hectares, the garden is home of around 10,000 species of native and exotic plants, that had been well preserved and managed by specialized gardeners, volunteers and dedicated scientists since 1822. Today the scientific head of the Botanical Garden is Dr. Barbara Ditsch, a woman with great knowledge and passion regarding plant conservation and management and to whom we are deeply grateful for sharing her knowledge and warm hospitality.

During this pleasant excursion, we could find a variety of native and endangered plants included in the red list of Saxony as Arnica montana; medicinal and toxic herbs as Colchium autumnale, tropical and subtropical aquatic, carnivorous or ornamental plants as Victoria cruziana, Nepenthes sp. and orchids respectively, as well as perennial plants and deciduous trees from Europe, temperate Asia, North America and the Mediterranean region. Also our excursion was warmed up with the visit into three wonderful and well managed greenhouses showing the tropical and subtropical regions, and even the humid weather of the Amazon or the warm and dry weather of Madagascar desert.

New concepts of conservation and plant management have been provided to our pool of knowledge, where we could learn that The Botanical Garden of TU Dresden is working with the aim to integrate several innovative proposals towards an important topic in this decade: “Ecosystem services”. In which it is relevant for the ex-situ plant conservation and for the local animal diversity (e.g. providing habitat for 120 bees that have been recorded here and in its surroundings), but also providing a harmonic space for tourism, education and research (estimated 100,000 guests/year), highlighting the multiple roles of botanical gardens within urban areas. This experience had contributed both in our cultural enrichment and also in our professional knowledge, in which the majority of us will be very glad to bring this innovative and multidisciplinary idea of conservation for our countries.
