the success of foliose lichen, old-growth forest lichen dependent on amount of light in surrounding environment dictates delicate balance between growth potential , desiccation damage. lobaria pulmonaria old-growth forest lichen transplanted 3 different boreal forest stands assess biomass , area growth. 3 stands had different amounts of light exposure, moistening , nutrient additions. 3 forest habitats included (1) even-aged young , closed canopy stand, (2) old forest gaps, (3) open clear-cut areas sparse regeneration of scattered trees no self shading branches. each of these environments offered varying amounts of light exposure. growth of l. pulmonaria highest in open sites, in species not occur naturally. lack of light seems strong limiting factor growth of l. pulmonaria. however, there no simple relationship between site factors , light because lichens desiccate @ different times of day. @ same time, l. pulmonaria has low tolerance prolonged high light, during desiccation times can neither repair damage nor acclimate.
