Paulownia tree are one of the plants that have the property of extremely rapid accumulation of plant mass. In this regard, interest in this tree culture has increased significantly in recent years. The purpose of this work is to study the adaptive capabilities of P. tomentosa in the conditions of Stavropol and the prospects for its further use for economic purposes and landscaping of the region. The object of the study was the plants of the collection of the Stavropol Botanical Garden (SBG). Archival data and accounting documentation were used to review the history of the introduction of Paulownia. Biometric measurements of plants were performed according to N.P. Anuchin (1982). The integral assessment of the prospects for the introduction of Paulownia plants was carried out according to the scale of P.I. Lapin and S.V. Sidneva (1973), modified and supplemented by M.A. Koltsova (1983). P. tomentosa has been introduced into the SBG since 1984. Currently, there are several groups of adult Paulownia specimens of various origins in the SBG. The height of adult trees in them varies from 4.3 to 9.0 m, the trunk diameter is from 2.7 to 19.5 cm. The growth of annual shoots reaches 120 cm. The article presents the timing of flowering and fruiting of Paulownia, the peculiarities of the development of culture when grown under different conditions. The methods of reproduction are described: seed and vegetative. P. tomentosa belongs to thermophilic plants — it starts and ends the growing season late. The lignification of annual shoots does not take place fully, as a result of which they are damaged by frosts. Young plants need winter shelter, and in the summer they need sufficient moisture. According to the conducted integral assessment, P. tomentosa belongs to the group of less promising species in the conditions of the SBG, but can be grown as a solitare and in a little groups.

Steppe ecosystems are the most important terrestrial ecosystems for the national economy in Russia, on which the bulk of Russian agriculture has been based for almost two centuries. At the same time, the steppe is one of the most vulnerable natural ecosystems, as it is influenced by various environmental factors (natural, anthropogenic, man–made). The most tangible environmental factor — anthropogenic — is the downside of human agricultural activity. The removal of virgin steppes for arable land, unregulated livestock, excess of pasture load in excess of permissible norms led to the loss of former biodiversity, a high degree of disturbance of steppe ecosystems, and in some cases, a complete loss of soil fertility and vegetation cover, and as a result to desertification of the territory. In the current situation, the steppe ecosystems of Russia, including the Stavropol Territory, need restoration measures aimed at reducing and preventing the scale of degradation of steppe territories, improving soil cover and vegetation, increasing biodiversity and productivity of natural grasslands. The lost steppe vegetation should be returned to its original habitat. It is necessary to gradually resume the native flora, based on the use of resourcesaving technologies for restoring natural vegetation and preserving virgin areas of steppe communities. However, the recognition by society of the indisputable importance and value of steppe ecosystems is no less significant. And of course, the legal status.
