The status of some herbaceous species populations in West Siberian subtaiga forests

Abstract

The coenopopulations of Bupleurum longifolium L., Pulmonaria mollis Wulf, ex Hornem., Angelica sylvestris L were studied in the territory of the experimental forest park of CSBG (Novosibirsk). The coenopopulations have a left-sided spectrum. The main method of reproduction of species − seed. In the intact pine-birch forest, coenopopulations of species with a low density of individuals develop. In weakly disturbed habitats (selective felling, periodic haying) the densities of individuals in B. longifolium, P. mollis increases, as well as old (in B. longifolium) or juvenile (in A. sylvestris) individuals fall out. Improving lighting here causes an increase in the size parameters of generative individuals and the acceleration of their development.
