The state of undergrowth, problems of renewal and spread of Arbutus andrachne L. within certain Crimean localities

Abstract

Field observations were carried out in order to assess the state of A. andrachne undergrowth and plantings in individual localities, as well as to assess the possibility of spreading plants beyond the territories where stable populations are formed. It was revealed that the undergrowth in the populations of the Mountainous Crimea has a low level of vital indicators and a small number, its number in individual generations varies significantly depending on the weather conditions of the growing season of the beginning of growth. In some localities, under favorable microclimatic and edaphorographic conditions, seed renewal in most cases has a mosaic character. Cases of single plants or small groups growing far beyond the isolated Crimean populations have been noted.
