“…This pool of species, including several nationally rare lichens, represents a community which is probably poorly developed where over-mature trees are normally absent, such as in managed forests. Calicioid lichens, well known as indicators of ecological continuity (Tibell 1992;Selva 2002), have a similar pattern among indicator species in the diVerent age classes, being more represented on over-mature trees. For example Cyphelium karelicum was considered by Thor (1998) as indicating continuity in spruce forests of Sweden.…”

Testing the relations between tree parameters and the richness and composition of lichen communities in near-natural stands could be a first step to gather information for forest managers interested in conservation and in biodiversity assessment and monitoring. This work aims at evaluating the influence of tree age and age-related parameters on tree-level richness and community composition of lichens on spruce in an Alpine forest. The lichen survey was carried out in four sites used for long-term monitoring. In each site, tree age, diameter at breast height, tree height, the first branch height, and crown projection area were measured for each tree. Trees were stratified into three age classes: (1) <100 years old, immature trees usually not suitable for felling, (2) 100–200 years old, mature trees suitable for felling, and (3) >200 years old, over-mature trees normally rare or absent in managed stands. In each site, seven trees in each age class were selected randomly. Tree age and..

“…In our analysis, nationally rare lichens correspond to the 'extremely rare species' which can be roughly compared to threatened species (Nimis and Martellos, 2008) according to IUCN criteria (2001) and therefore targeted for conservation purposes at the national level. Calicioid species, including lichens and fungi traditionally referred to Caliciales, are mostly related to old-growth forests and are considered as suitable indicators of forest sites worthy of conservation and of forest continuity (Selva, 2002). One-way ANOVA was applied to test the effect of the forest successional stage on species richness both at the tree and at the plot level.…”

“…In this framework, research has also focused on the comparison between forests managed for timber production and forests managed for old-growth, showing that old-growth forests play a key role for the conservation of rare (e.g. Pykälä, 2003) and calicioid species (Tibell, 1992;Selva, 2002). Nevertheless, a balance should be found between conservation and productivity, estimating to what extent the oldest age classes in forests managed for timber production could compensate for the scarcity of forests managed for old-growth conditions.…”

“…Calicioid lichens are usually employed as suitable indicators of forest continuity and/or of the conservation importance of stands (Selva 2002), since they are related to habitats that are becoming rare in managed forests (e.g. large/old trees, and CWD).…”

Lichen diversity on stumps in relation to wood decay in subalpine forests of Northern Italy

et al. 2008

Although several studies demonstrated the importance of dead wood for lichen conservation in N-Europe and N-America, the lichen biota on dead wood was poorly studied in the Alps, where stumps represent one of the main available dead wood type. This work aims at evaluating species richness and composition of lichens in relation to the decay of stumps in subalpine forests of the Italian Alps. Differences in species richness between three decay stages were tested using a one-way ANOVA, while the pattern of species composition was evaluated with non-metric multidimensional scaling and an Indicator Species Analysis. Overall, 69 species were found and wood decay proved to be an important factor influencing lichen communities on stumps in our subalpine forests. Despite the fact that the mean number of species per stump did not differ between the three decay stages and lichen communities broadly overlapped, a main pattern of species turnover was identified across wood decay process as well as some indicator species for each decay stage. During the decay process, lichen communities change functional and ecological composition as an adaptive response to the continuous change of substrate. Since stumps host several nationally rare species, which are related to different stages of decay, they could have a relevant role in lichen conservation in managed forests where other types of dead wood are normally absent
