The escape of alien species from botanical gardens: a new example from Ukraine

Zusammenfassung: | The spontaneous appearance of the annual plant,
Veronica cardiocarpa
Walp. (
Plantaginaceae
), from Central and Minor Asia was recorded in the O.V. Fomin Botanical Garden of the Taras Shevchenko National University of Kyiv in 1983 as a result of unintentional introduction. It was the first documented occurrence outside of its natural range.
V. cardiocarpa
has been widespread within the Botanical Garden since 2007, and the first location outside the Botanical Garden was discovered in 2010. Later, the presence of
V. cardiocarpa
was noted in Chernihiv, as well as new locations in Kyiv. This species has become a new invasive plant of the flora of Ukraine, because it occupies new areas and shows high seed productivity. Additionally,
V. cardiocarpa
has high seed germination under certain conditions that were established during our experiment, consisting of four variants and a control. The conditions of the second variant—cold stratification with low positive temperatures for two months and germination of seeds at + 18–20 °C—were the most favourable—49 ± 4.36% germinated seeds began to appear on the third day after completion of stratification. Moreover, some indirect facts show that
V. cardiocarpa
is is already deeply integrated in local urban ecosystems. Therefore, the main stages of the adaptation and spreading of
V. cardiocarpa
have been studied and described in Ukraine in this research. Information about a new location of this species in the Russian Federation significantly changed the understanding of
V. cardiocarpa
distribution in Eastern Europe. Finally, in this article, we discuss the important matter of dealing with the
V. cardiocarpa
invasion, and some approaches to prevent similar cases of the new alien species penetration through collections of botanical gardens and arboreta. |
