“…In the South Podlasie Lowlands, it is considered critically endangered. According to the authors, the population of this species in 2001 was several dozen; however, in 2009 and 2013, the species was represented by only a dozen individuals [58]. Additionally, three populations of A. sylvestris were located in the Lublin Uplands [59].…”

The protection of biological diversity in nature and in agriculture, including the production of ornamental crops, has become increasingly important in Poland as well as worldwide. The Convention on Biological Diversity, signed in 1992 at the Earth Summit of the UN in Rio de Janeiro and ratified by the Polish government in 1995, imposed new regulations related to the protection of nature and the genetic resources of cultivated crops in Poland. The conservation of the genera, varieties and cultivars of ornamental geophytes—a group of plants of great interest from a botanical and physiological, but also a horticultural point of view—takes place in situ (both in nature and in the places of cultivation) and through the establishment of ex situ gene banks and collections. The natural genetic resources of ornamental geophytes include species from the genera Allium, Fritillaria, Gladiolus, Iris, Leucojum, Lilium and Muscari, among others, and more than a dozen species are protected by law due to varying degrees of threats. Botanical gardens play an essential role in the conservation of endangered species. Their activities focus on genus monitoring, managing ex situ gene banks (including National Collections), developing propagation methods and carrying out their reintroduction. In order to protect the national genetic resources of cultivated plants, the National Centre for Plant Genetic Resources at the Plant Breeding and Acclimatisation Institute—National Research Institute, under the auspices of the Ministry of Agriculture and Rural Development, was established. Concerning ornamental geophytes, the National Centre coordinates two field collections of cultivars of the genera Gladiolus, Lilium, Narcissus and Tulipa, which are of great economic importance and have a long tradition of breeding in Poland. The first one is located at the National Institute of Horticultural Research in Skierniewice (central Poland), and the second one is at the Experimental Substation of Variety Testing in Lisewo (northern Poland). The history of tulip collections in Poland dates back to the 1960s. At that time, the first breeding work for this species began. The collection of bulbous crops in Skierniewice is currently one of the largest in Poland, with a total of 934 accessions. Most of them are tulips (522) and lilies (222). Other plants in the collection in Skierniewice are gladiolus and narcissus. The most valuable accessions are grown under special protection (tunnels with dense nets) to guard against insects and maintain a mild climate inside. The genetic resources of the ornamental bulb plant collection in Lisewo currently consist of 611 accessions, mainly tulips (358), daffodils (121) and gladioli (132). All bulbous crops in both collections (Skierniewice and Lisewo) are grown in accordance with all principles of agrotechnics (negative field selection, fertilisation, soil maintenance). A particularly important task of botanical gardens, universities, research institutes and the National Centre is leading research on the methods of storage for survival organs, in vitro cultures and cryopreservation. We have discovered that the various activities for the species conservation of ornamental geophytes require a great deal of constantly deepening knowledge and extraordinary measures, including frequent monitoring of the effects of the applied measures.

“…In relation to thermal regime, this species is submicrotherm-submesotherm; in relation to continental climate regime, it is subcontinental; in relation to climate, it is subarid-subhumid; in relation to cryoregime, it is cryophytehemicryophyte; according to the salt regime -the type of poor and rich soils; according to the moisture regime, there are species from slightly alternating-humid to strongly alternatinghumid soils; according to the regime of light, there are species of open spaces and sparse forests (Tsyganov, 1983). It grows in moist, marshy, or peaty meadows, but also tolerates drainage well (Mazáč, 2007) on the xerothermic grasslands (Krechowski et al, 2015) and also on glades of mixed and broad-leaved forests, meadow-steppe slopes, among shrubs on rich and mediumrich soils (Solomakha, 2017).…”

Ecological analysis of the existing phytocoenological relevés was carried out, including the new localities of Thesium ebracteatum Hayne in the Middle Dnipro region. To study the coenotic features, the ratio of diagnostic species of different classes of vegetation in the communities was found. In the western part of the area, including the territory of Ukraine, this species grows in psamophytic communities, the basis of which is species of the Trifolio-Geranietea sanguinei class. In the eastern part of the area, including the territory of the Russian Federation, the species grows in steppe communities with a predominance of species of the Festuco-Brometea class. The analysis of ecological features of the species using the method of phytoindication showed the two clusters with the biggest differences by the acidity indicator. In the central part of Ukraine and in Europe, this species grows on soils with a higher acidity. On the contrary, in the eastern part of the area (territory of the Russian Federation), it mostly occurs on carbonate-enriched soils with low acidity. The growth of T. ebracteatum on more acidic soils in the western areas should be explained by a more humid climate.
