IntroduzioneLe foreste hanno un ruolo fondamentale nel ciclo globale del carbonio (IPCC 2007). La ratifica del Pro tocollo di Kyoto comporta la realizzazione di una se rie di interventi per quei Paesi che hanno assunto l'obbligo di ridurre tra il 2008 e il 2012 le proprie emissioni rispetto al 1990. Tra questi, l'Italia ha preso l'impegno di ridurre le proprie emissioni del 6.5 % (Pettenella & Zanchi 2006). Tra le attività previste per la mitigazione dei cambiamenti climatici, il Pro tocollo di Kyoto include anche attività riferibili a Land Use, Land Use Change and Forestry (LULUCF); in pratica viene riconosciuto un importante ruolo di stabilizzazione delle concentrazioni di gas serra nel l'atmosfera agendo sugli usi del suolo. Per essere ammissibili, le attività LULUCF devono aver avuto inizio non prima del 1990 ed essere intenzionali, cioè prodotte da interventi diretti, volontari, non naturali (Ciccarese & Pettenella 2005). Questo ha, di fatto, ac cresciuto l'importanza del ruolo ecologico e quindi della funzione socio-economica svolte dalle foreste. Infatti, il comparto agricolo e forestale gioca un ruo lo fondamentale come "pozzo" (sink) di carbonio e sono considerate a loro volta delle vere e proprie ri serve (carbon stock). L'Intergovernmental Panel on Cli mate Change (IPCC 2007) ha dimostrato che il settore forestale ha il maggior potenziale per ridurre i livelli di CO 2 , a costi ragionevoli, nei prossimi 25 anni, ri spetto a tutte le altre attività di mitigazione (Bette lheim 2008). Il Protocollo di Kyoto indica diverse strategie per aumentare gli stock di carbonio materia lizzate nell'art. 3.3 "Nuove piantagioni" e nell'art. 3.4 "Miglioramento degli stock" delle foreste esistenti.Da molti anni diverse amministrazioni pubbliche, The purpose of the study is to calculate CO 2 emissions deriving from the VII SISEF Congress activi ties. The idea is to provide on add a value to the event through the realization of voluntary offsetting actions. These actions are local projects of sustainable forest management and tree plantation in order to improve carbon stock. Specifically, the emissions offset will be realized through direct actions: (1) a plantation of about 50 trees in the parking of STAT department of the University of Molise; (2) implementation of an arbo retum in the Apennine flora Garden of Capracotta; and (3) a coppice conversion plan in Monte Vairano (Campobasso), owned by the University of Molise. The methodology foresaw the currently stored carbon ba seline calculation and the expected time accumulation for the entire duration of the actions. The STAT De partment of the University of Molise will bind its interventions in order to avoid additionality feature and will monitor over time to ensure the effects permanence in carbon storage. The total emissions calculations of Congress amounted to around 12 Mg CO 2 and proposed offsetting actions largely exceed that value.

“…In all cited cases, reliable data on the specific apparent density of the shrub (i.e., weight/AV, kg m -3 ) are needed. Chirici et al (2009) and Bacciu (2009) applied an expeditious method to estimate a "volume index" as the product between the vegetation coverage degree and shrub height, while in recent years a growing interest was addressed to the application of the Light Detection And Ranging (Li-DAR) systems which estimates the AGB stock from the relationship between plant weight and canopy height or volume (Garcìa et al 2010, Maselli et al 2011, Corona et al 2012.…”

As a result of Kyoto Protocol agreements, the scientific community increased its efforts to enhance the availability of biomass and organic carbon stock data in forest ecosystems. Nevertheless, a considerable data shortage has been recognized in estimating the stock of above-ground biomass (AGB) in Mediterranean maquis systems. This work aims at contributing in addressing such shortage by testing quick and non-disruptive methods to estimate the AGB stock in maquis species. Two methodologies were tested in three widespread sclerophyllous evergreen species (Pistacia lentiscus, Euphorbia dendroides, and Cystus monspeliensis). Both methodologies were based on the estimation of the apparent volume (AV): the first one assumed the shrub shape (or canopy) to be similar to a regular tridimensional solid, while the second method was based on plant digital images analysis. Results showed some differences in AV values estimated through the two methodologies, although a high correlation was found between them (R 2 = 0.92-0.98) and with the AGB weight obtained from plant samples (R 2 = 0.89-0.96). As a consequence, the shrubs apparent density values (i.e., weight/AV) vary depending on the method used for AV estimation. This should be taken into account when AV is used for AGB estimation. Besides, measurements of above-ground biomass were carried out to characterize the studied area. Results showed high variability in AGB values, ranging from 7.04 to 48.05 Mg ha -1 of dry matter.

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 relevés 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.
