Abstract
Results of 20 cenopopulation (CP) studies for Althaeae officinalis L. (a rare species in the Republic of Bashkortostan (RB)) in the northern border of its habitat are shown. The demographic structure, morphometric parameters, and individual life states are studied; life optima are shown. Most CPs of A. officinalis under study have low density (1–4 individual/m2) and an incomplete ontogenetic spectrum. The vitality type of A. officinalis CP changes from florescent to depressive. Ecological and phenocenotic optima are generally not the same in CPs. Optimal conditions for A. officinalis growth are reed littoral communities at the periphery of Phragmites australis underbrush; in communities disturbed by pasture, a decline in the state of A. officinalis CP is observed.
