“…Geologicamente le montagne delle Serre sono di natura cristallina. Morfologicamente si identificano due brevi creste montuose parallele a questo tratto appenninico e i terreni hanno una tessitura sabbioso-argillosa (Mercurio & Mercurio 2008). Il clima cambia con l'altitudine e l'esposizione.…”

IntroduzioneLa Calabria è una delle regioni italiane con maggiore copertura forestale. I boschi rappresentano, infatti, più del 40% del territorio regionale (612.931 ha) rispetto a una media nazionale del 34.7% (INFC 2005). Fra le varie tipologie boschive le conifere rivestono una grande importanza, sia per l'industria boschiva, sia dal punto di vista ambientale e paesaggi- Despite these woodlands are of great importance both economically and from a conservationist point of view, biodiversity of moth has been investigated in a non occasional way only for the Sila Calabrian black pine forests, while the silver fir woods of the Serre have been only recently the subject of studies. Apart from increasing the knowledge on the biodiversity of the nocturnal Lepidoptera hosted by Calabrian coniferous forests, the aim of this study was to compare the sampled communities to find out the main differences and their causes. The sampling was conducted in 9 sites for each forest type, distributed so as to cover the different development stages of ecological succession, from open areas to mature woodlands. A light trap was monthly placed at each site from May to November 2015, for a total of 126 nights/trap. The two communities showed low similarity indices (Classic Jaccard = 0.396; Sorensen Classic = 0.568), due both to the component trophically linked to the dominant forest species and to the component linked to the herbaceous layer. In fact, the dominant species in the Calabrian black pine wood and in the silver fir wood (Thera firmata and Macaria liturata, respectively) are absent or only occasionally present in the other forest type, and the community linked to the herbaceous layer is much better represented in the Calabrian black pine forest (29.7% of the total) than in the silver fir forest (14.9%). The arrangement of the Sila landscape, where Calabrian black pine forests alternate with pastures, shrubs and cultivated fields, seems to be the cause of the increased presence of species related to non-forest vegetation layer, while the micro-climatic conditions of the silver fir forest, more humid and temperate, favor the presence of a limited share of species trophically associated with herbaceous plants, which, however, have a high bio-geographical interest.

“…La distribuzione della luce sotto la copertura arborea è strettamente dipendente dal LAI e dal grado di copertura di un popolamento forestale e influenza la numerosità (Mercurio & Mercurio 2008) e la distribuzione della rinnovazione (Pastorella 2011). Secondo quanto dimostrato da Machado & Reich (1999), il LAI spiega il 90% della variazione giornaliera del flusso di fotoni, pertanto, il suo studio appare come un metodo efficiente per la stima della capacità di tolleranza all'ombra degli individui che crescono sotto copertura.…”

) and it can be measured using an angle of 180°. Instead, the canopy cover is the percentage of forest area occupied by the vertical projection of tree crowns; consequently, LAI expresses the canopy closure rather than the canopy cover. This paper focuses on the estimation of LAI and canopy cover percentage in 54 sampling points randomly distributed over the main forest types of Trentino (beech forests, Scots pine forests, Norway spruce forests and European larch forests). The main purpose was the analysis of relationship between LAI and canopy cover percentage, the latter measured with two different techniques: visual estimation and estimation using the spherical densiometer. In the last part of the paper, LAI data collected in the four main forest types of Trentino are compared with values reported in the literature for the same forest types.
