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

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.
