INDEX SPORARUM ET SEMINUM 2019. BOTANIC GARDEN OF PETROZAVODSK STATE UNIVERSITY

Botanical Garden of Petrozavodsk State University is one of the northern gardens of Russia. It is located in the mid-taiga subzone of the European taiga and in climatic conditions that correspond to zone 4. Karelia’s climate is temperate continental with some features of the marine influence. The climate is characterized by mild winters, short, cool summers, significant cloud cover, and unstable weather conditions during the entire year. The average air temperature is 3º C. The region is characterized by excessive humidity, its dampness due to relatively little incoming heat and well-developed cyclonic activity during the seasons. The precipitation is 750 mm per year.

The large area of ​​the Botanical garden (367 hectares) allows both to contain collections of plants ex situ and to preserve plants in their natural habitats (in-situ). The garden is located in a picturesque ridge landscape, which is formed by the ancient rocks of the Proterozoic age of 2 bln years. The soils are thin, mainly sandy loam with an acid reaction. Large nature zone (330 ha) occupied by forests (80 %), meadows (15 %), rocks and little swamps, where 400 species of vascular plants grow in-situ.

Main collection departments of the Botanic Garden are arboretum, the collection of perennials and collection of fruit and berry plants. The present collections and exposures include more than 2200 species, subspecies, varieties, forms and cultivars growing ex-situ.

The Botanic Garden of Petrozavodsk State University has been exchanging seeds for more than half a century. Many plants of modern collections came to the garden thanks to the support of colleagues from various botanical organizations of the world. We take this opportunity to thank you for your cooperation and look forward to continuing our common work on the conservation, study of plants and environmental education.
