International collaboration

National Botanic Garden takes part in the international seed exchange among world botanic gardens since its establishment in 1956. Our seed exchange partners are more than 600 botanic gardens and arboreta in the entire world. Seeds of known provenance are collected and seed exchange catalogue (Index Seminum) containing about 500 accessions is issued each year. In the last two years it is distributed only via e-mail. About 500 botanic gardens and arboreta have active seed exchange contacts with NBG each year. It means, not only receive NBG Index Seminum, but also send their seed requests and/or Index Seminum back, and accordingly get requested seeds and send them to NBG. For example, in 2019 Index Seminum was sent to ~600 partners, received were from ~200 ones, sent ~1500 and received ~1000 seed samples.

In a result of many years collaboration with Goetheborg Botanic Garden (SE) and Kew Royal Botanic Gardens (UK) fundamental taxonomic and molecular researches in Iris, Muscari, and Allium were carried out. As a result of joint expeditions to Turkey, Caucasus and Middle East and additional investigations, several new species were discovered. Collections of world importance of onion species (Allium), Juno irises (Iris subgen. Scorpiris), and Muscari arecreated in the NBG. Some results of this work are published:

N. Ikinci, T. Hall, Dolores Lledó, J. J. Clarkson, N. Tillie, A. Seisums, T. Saito, Madeline Harley and M. W. Chase. Molecular phylogenetics of the juno irises, Iris subgenus Scorpiris (Iridaceae), based on six plastid markers. Botanical Journal of the Linnean Society, 167, 2011, pp. 281–300.

In the framework of collaboration with the Vilnius University several joint expeditions were organized. The expedition-conference „Biological diversity and cultural heritage of Kupiškis region”, and meeting of bilateral working group were organized. Results of this collaboration were published in a poster presentation and a paper:

Jakobsone G., Dapkūniene S., Cepurīte B., Belogrudova I.: The conservation possibilities of endangered orchid species of Latvia and Lithuania”. Monographs of Botanical Gardens (European botanic gardens together towards the implementation of plant conservation strategies), Warsaw/Rogow, Poland, Vol.1: 2008, 65-68.)

In a spirit of collaboration with Tartu University Botanic Garden, mutual visits of the groups of specialists are frequent; dendrology specialists of NBG performed expertises of historical trees of Tartu Botanic Garden using acoustic tomography. In 2011, the joint project “Smart Garden” (INTERREG Estonia-Latvia cross board program project) has been launched, which will facilitate creation of modern informative infrastructure in both gardens.
