Boreal forests are intensively managed to maximize wood gathering notwithstanding the importance of maintaining biodiversity. The preservation of endangered and rare plants has become an important but complicated task in times when drastic forest ecosystem changes are observed following clearcuttings. The Kaunas Botanical Garden of Vytautas Magnus University implements the MEKODINA project (grant No. SIT-1/2015 funded by the Research Council of Lithuania) that includes the task of protecting rare understory plants after clear-cuttings. We aim at determining the “minimum required conditions” for the survival of rare and endangered species in the clearcut forest areas. While implementing the project several new localities of rare and protected plant species were discovered which led to new sets of information about Arnica montana L., Pulsatilla patens (L.) Mill., Silene lituanica Zapał., as well as V. myrtillus var. leucocarpum Haussm. and were included in the protected species information system (PSIS). Individuals of A. montana and P. patens that are recorded in the Lithuanian Red Data Book were found only in very few isolated plots. Our investigations corroborated the crucial influences in the development of juvenile populations of Lycopodium annotinum L., L. clavatum L., Diphasiastrum tristachyum (Pursh) Holub, and D. complanatum (L.) Holub. We ensured the protection of these archaic plants by marking their habitats. The conditions of other plant populations were evaluated and means for their protection were proposed. - The endangered plant species need careful restoration activities that may include population translocations or re-introductions, in order to prevent their extinction. We will continue investigations on ex situ propagation and preservation of rare and endangered plants at a specific part of the living collections in Kaunas Botanical Garden.
