Dynamics of the species composition of honey plants on postagrogenic and forest lands

Abstract

Data on the dynamics of the species composition of resource plants on postagrogenic and forest lands are presented. The object of the study is abandoned arable land and fields, felling with the growth of pine and felling with forest crops. Over the period from 2006 to 2021, the species composition and the projective cover of vegetation have changed. Judging by the value of the coefficient of floristic generality of P. Jaссard, the species on postagrogenic and forest lands in 2006 coincided only by 27%, and 15 years later - by 36%. Thus, as the forest environment is formed on abandoned agricultural lands, the species composition of vegetation on these categories of land is leveled. The honey productivity of plants on postagrogenic lands is generally higher than on forest lands. The purpose of the study is to establish the dynamics and features of overgrowth of post-agrogenic lands with woody vegetation and honey plants.
