Title: Assessing the biomass of shrubs typical of Mediterranean pre-forest communities Authors: Corona, Piermaria; Pasta, Salvatore; Giardina, Giovanni; La Mantia, Tommaso Abstract: One of the most outstanding issues of current environmental research is the need of reliable assessments of carbon stock (i.e. above-ground (a.g.) and below-ground biomass, deadwood, litter, and organic soil matter) within forest ecosystems. Although shrub vegetation plays an important role in accumulating carbon in many Mediterranean environments, there is still very little knowledge on the carbon they store. In this article, we analyze the a.g. carbon stock of several Mediterranean shrubby communities in Sicily (Italy), dominated by Pistacia lentiscus, Chamaerops humilis, Euphorbia dendroides and Spartium junceum. Plant samples for each species were selected, and morphometric attributes (height, crown diameter, diameter at breast height, etc.) were measured to establish models for estimating a.g. biomass. Dendrometric data were also used to support the assessment of shrub biomass at community level by coupling them with the coverage of the considered woody species estimated from several hundreds of phytosociological releve´s carried out on pre-forest Sicilian communities. Although the results of such an approach have to be considered as rough assessments, the trial proves interesting, given the lack of information on stand biomass of pre-forest vegetation within the Mediterraean region.

Title: Rimboschimenti e lotta alla desertificazione in Italia Authors: Corona, Piermaria; Ferrari, Barbara; Iovino, Francesco; La Mantia, Tommaso; Barbati, Anna Abstract: Questa monografia propone una lettura critica sul ruolo attuale del rimboschimento nella prevenzione e mitigazione dei processi di desertificazione in Italia. Le potenzialità del rimboschimento sono inquadrate in una prospettiva multifunzionale e sinergica che comprende le ricadute ambientali di questa attività anche in termini di assorbimento del carbonio atmosferico e potenziamento della biodiversità, oltre che di conservazione del suolo e recupero e riqualificazione di paesaggi degradati. L’obiettivo è delineare una strategia di lotta alla desertificazione applicabile a livello regionale, nel quadro degli strumenti programmatici e di governo del territorio rurale e fornire orientamenti tecnici per la progettazione dei rimboschimenti su terreni degradati

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.
