Hoffm. was analyzed in the Vodlozersky National Park (Karelia, Russia), for middle boreal forest stands having a time-since-disturbance spanning 80 to 450 years. To estimate the age of the last disturbance, a method of evaluation for the tree population structure was applied. The forest stand communities belonged to a successional series: middle-aged aspen – mixed aspen-spruce </span><span>– </span><span>pre-climax spruce – climax (old-growth) spruce forest. All thalli (1055) of </span><em>L. pulmonaria </em><span>from all substrate units (165, separately standing or lying trees and shrubs) were described within 7 sample plots of 1 ha. For each thallus, the area (cm</span><span>2</span><span>) and the functional-age group were determined. The number of </span><em>Lobaria </em><span>thalli per ha, number of substrate units, number of substrate types (living, standing dead and lying dead trees of different species) colonized by </span><em>L. pulmonaria</em><span>, as well as number of substrate types on which the lichen had completed its life cycle increased with time-since-disturbance. </span></p></div></div></div> ER -
