Introduced plants in the specially protected natural area “Forested ravine near the village of Vlasyevo” in Moscow region

In 2017–2022, field studies of the natural complexes of the natural monument “Forested ravine near the village of Vlasyevo” (Moscow region) were carried out. Most of the area is currently occupied by broad-leaved forest. On the left bank of the river Gremyachevka at the turn of the XIX–XX cen-turies S.D. Rzhevsky, the landowner, created an arboretum with a collection of conifers, which was considered one of the richest in Russia. It was established that the age-old park plantings, including conifers, identified on the right bank of the river Gremyachevka, belong to another estate “Vysokoye”, about which nothing was previously known. In total, 34 species of cultural origin were found, of which 21 taxa (61%) are found in centuries-old park plantings, and 13 species appeared later. Introduced conifers are represented by 10 taxa (Abies sibirica, Larix decidua, L. sibirica, Pinus nigra, P. sibirica, Picea abies, P. glauca, P. obovata, P. pungens and P. pungens ‘Glauca’), most of which comes from the collection of S.D. Rzhevsky. Only P. abies, planted in Soviet times, was able to naturalize and form a small undergrowth. Of the invasive species with the status of Amelanchier spicata, Populus alba and Sorbaria sorbifolia were found as part of old park plantings. It is likely that the appearance of Symphytum caucasicum and Caragana arborescens near the village occurred at the end of the XX century. It was noted that all introduced species, regardless of the date of planting and the presence of the status of an invasive species, were found at the places of their planting. Since only foundations remained from the noble estates themselves, park plantings on the territory of the natural monument need protection and further monitoring as preserved natural and historical objects.
