“…The selection of indicators, however, may be problematic (e.g. Kerr et al 2000;Landers et al 1988;Noss 1990), and their correlation with the overall diversity must be tested (Hedenås and Ericson 2000;Bergamini et al 2005;Nascimbene et al 2006;Nordén et al 2007). For a rapid assessment of tree-level species richness both structural and biological indicators could be used.…”

Influence of tree age, tree size and crown structure on lichen communities in mature Alpine spruce forests

et al. 2008

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..

“…Epiphytic lichens inhabiting Aleppo pine tree bark were studied (Bergamini et al 2005) by randomly selecting five pine trees and vertically dividing them into four sectors according to the cardinal points. Furthermore, four horizontal sectors (10 cm width) were designed on the bark.…”

“…In most of the studies, high abundance and cover were recorded in the first 2 years after a fire, followed by a decrease in the long term according to the ''initial floristic model'' (Verroios and Georgiadis 2002), although there were many differences depending on many factors (Noble and Slatyer 1980;Pausas 1999). We used indirect indices to characterize the faunal community, including indices of habitat diversity (Kuuluvainen and Laiho 2004), deadwood (Dudley et al 2004), and lichen diversity (Bergamini et al 2005).…”

Structural patterns and biodiversity in burned and managed Aleppo pine stands

et al. 2008

Increasing anthropic pressure is making forest fires more frequent in the Mediterranean Basin and therefore affecting the response of native flora and fauna. Two large fires occurred in summer, 1994, in the Southeastern Iberian Peninsula. Aleppo pine, the main tree species, regenerated naturally after the fire. In this study we are interested in strategies for maximizing Aleppo pine tree recovery and conservation of its ecosystem. We performed thinning and pruning in the pine tree stands 5 and 10 years after the fire and took measurements on structural patterns and plant diversity using several indices. In addition, we measured macro-lichen and faunal diversity indirectly. Results show significant differences between treated-burned plots and untreatedunburned plots. The plots thinned 10 years after the fire and the unburned plots (mature stands) showed a regular, non-aggregated distribution and a low diameter differentiation. Also, these plots showed similar plant diversity values. The silvicultural treatments did not significantly affect the fauna and lichen index values. The high intensity of thinning and late pruning applied to young Aleppo pine stands improved the structural pattern and plant diversity.

“…Indicators of biodiversity are surrogates for total biodiversity estimates that can be more easily sampled (Noss 1990;Lawton et al 1998;Lindenmayer et al 2000;Will-Wolf et al 2002;Bergamini et al 2005). For example, Kerr et al (2000) demonstrated that Hymenoptera morphospecies are valuable predictors of total species richness at the landscape scale in an oak savanna ecosystem.…”

Testing indicators of epiphytic lichen diversity: a case study in N Italy

2006

The predictability of a standardized and widely used biomonitoring method for estimating total lichen diversity on trunks (LDV-index) was tested. The study was carried out in Veneto (NE Italy), on 34 randomly selected trees in five sites in different landscape contexts. Two sets of biodiversity data were obtained from each tree: (1) the LDV index based on species frequency within a standard sampling grid positioned on a limited part of the trunks only (2) the total number of species found on the trunks. Total species richness on trunks is significantly related with the LDV index, which suggests that the LDV standard methodology can be used also for estimates of lichen diversity. Even a LDV index based on macrolichens, or on large-lobed foliose lichens only, still permits reliable estimates of total diversity on the trunks.
