Title: Sistemi di tariffe di cubatura per le fustaie di pino d’aleppo, pino laricio e pino domestico della Sicilia Authors: Corona, Piermaria; Cibella, Roberto; La Mantia, Tommaso; Chiriacò, Maria Vincenza Abstract: The aim of this study is to set up one-way volume table series to predict stem volume of the main conifers in Sicily, namely Italian stone pine, Aleppo pine and Corsican pine. For each species the relationships between height and tree diameter at breast height (dbh) resulted well represented by the semilogarithmic function, which was established as «guide line» of the height-diameter relationship. Adapting each height - dbh series according to the inclination of the «guide line», a set of isomorphic height curves was obtained for each species. Corresponding volume series was obtained from each height series on the basis of National Forestry Inventory volume tables. Oneway volume table series are of considerable usefulness in the context of forest management since they represent estimation tools with flexible application at different levels of forest management.

Title: Tavole di cubatura di popolamento per i soprassuoli forestali della Sicilia. Authors: Corona, Piermaria; Cibella, Roberto; La Mela Veca, Donato Salvatore; Pizzurro, Giuseppe Abstract: The aim of this study was to set up stand volume tables for easy and reliable estimation of the woody mass of coppices and high forest stands in Sicily. In this note we describe the statistical analyses which were carried out and we discuss results and their potential application. The use of stand volume tables is suggested mainly when it is possible to adopt quick, effective procedures for the assessment of the unitary basal area: in particular, the major potential is for surveys based upon relascope estimation of basal area in correspondence of sample points positioned according to probabilistic sampling schemes
