“…However, the decomposition phase of the dead wood is not noted. This information is crucial to assess the dead wood density from literature values [9,12]. A specific study on the determination of the C-stock in this dead wood compartment is therefore needed.…”

“…In total, we selected 174 wood density values from the literature. The range of these values was large, which is due to the geographical dependence of this parameter [12,23,30,46]. This large range could possibly also be the consequence of the fact that different methods were applied to measure the wood density.…”

“…Most forest inventories are firstly meant for sound forest management practices and are intended to monitor the wood volumes of economical interest. Biomass measurements are usually not included in the sampling procedure [12]. An exhaustive review of the various forest inventories conducted by the member states in the European Union and an analysis of their potentials to meet the requirements under the KP were developed in 2000, as represented in a synoptic table by Laitat et al [31].…”

Growing stock-based assessment of the carbon stock in the Belgian forest biomass

et al. 2005

-Belgian forests covered 693 181 ha in 2000, representing 22.7% of the total land area. As no biomass or carbon stock data are included in the Flemish and Walloon regional forest inventories, species-specific wood densities, biomass expansion factors s.s. and carbon content values were critically selected from the literature. Based on these conversion and expansion factors, and on data from the forest inventories, the total C-stock in the living biomass of productive Belgian forests was assessed at 60.9 Mt C in the year 2000. The overall mean C-stock amounted to 101.0 t C ha -1 . This value was in the higher range of values reported for the neighbouring countries, mainly due to a high mean growing stock in the Belgian forests (261.9 m 3 ha -1 ). The conversion from wood volume to wood biomass based on wood density values reported in the literature appeared to introduce the largest variability in the assessment of the carbon stocks. Additional measurements of wood densities in Belgian forests could help to reduce the uncertainty related to this factor. Because of the time-consuming and destructive character of the determination of biomass expansion factors s.s. (BEFs), the establishment of new BEFs does not have the highest priority in the framework of improving the assessment of the biomass carbon stock in the Belgian forests. As the median C-content value for all species except beech was equal to the default IPCC-value of 50% carbon in dry matter, it seems appropriate to use this value for future calculations.forest inventory / carbon stock / biomass expansion factor / wood density / aboveground and belowground biomass / carbon content Résumé -Estimation des stocks de carbone dans la biomasse des forêts en Belgique. La forêt belge couvrait 693 181 ha en 2000, ce qui représente 22,7 % de la surface totale du pays. Les inventaires forestiers flamands et wallons n'incluent pas de mesures directes de biomasse ou de stock de carbone. Pour calculer les stocks de carbone dans les arbres forestiers à partir des volumes de bois fort, les infradensités du bois, les facteurs d'expansion de la biomasse et les teneurs en carbone ont été sélectionnés dans la littérature. En 2000, les stocks de carbone dans la biomasse des forêts belges productives étaient de 60,9 Mt C, soit 101,0 t C ha -1 . Cette dernière valeur est relativement haute comparée avec celles observées dans les forêts des pays avoisinants, à cause d'un grand volume de bois fort dans les forêts belges (261,9 m 3 ha -1 ). L'infradensité du bois semble être le facteur qui introduit la plus importante variabilité dans le calcul des stocks de carbone dans la biomasse. Des mesures complémentaires des infradensités du bois des essences les plus communes en Belgique pourraient aider à réduire significativement les incertitudes sur les mesures des stocks de carbone dans les forêts. La détermination expérimentale des facteurs d'expansion est coûteuse en temps et se base sur des analyses destructives. Ainsi, l'obtention de facteurs d'expansion propre à la situati...

Afforestation/reforestation of New Zealand marginal pasture lands by indigenous shrublands: the potential for Kyoto forest sinks

et al. 2005

-New Zealand will use the afforestation/reforestation (A/R) provisions of article 3.3 of the Kyoto protocol to help offset greenhouse gas emissions during the first commitment period, 2008 to 2012. We assess here the potential initial C sink available from A/R of marginal pasture lands by New Zealand's most common shrubland species: mānuka (Leptospermum scoparium) and kānuka (Kunzea ericoides). Plotbased mensuration shows that mean net C accumulation rates for mānuka/kānuka shrubland are in the range 1.9 to 2.5 t C ha -1 yr -1 , when averaged over the active growth phase of about 40 years. Estimates of the change in mineral soil C with shrubland A/R of grassland suggest small losses occur, although these appear to be largely offset by accumulation of C in the litter layers. Analysis shows that nationally there are about 1.45 Mha of marginal pastoral land suitable for A/R by indigenous shrubland or forest. This area could accumulate about 2.9 ± 0.5 Mt C yr -1 , a significant offset to New Zealand's annual energy-related CO 2 emissions of 8.81 Mt CO 2 -C yr -1 . An initial economic analysis of livestock farming for a region with large areas of land marginal for sustained pastoral agriculture suggests "carbon farming" may prove an attractive alternative land use if international prices for biomass-C reach about €10 per tonne CO 2 . afforestation / reforestation / Kyoto protocol / carbon sink / shrublandRésumé -Boisement/reboisement des pâturages marginaux de Nouvelle-Zélande par des formations arbustives indigènes : potentiel pour les puits de carbone du protocole de Kyoto.

Nous évaluons ici le potentiel initial de puits de C rendus disponible par l'A/R des pâturages marginaux par les espèces arbustives les plus communes de Nouvelle-Zélande : le mānuka (Leptospermum scoparium) et le kānuka (Kunzea ericiodes). Les mesures réalisées sur des parcelles d'étude de comparaison par paire montrent que la moyenne du taux net d'accumulation de carbone pour le mānuka/kānuka, sur une période d'environ 40 ans de la phase de croissance active, est de l'ordre de 1,9 à 2,5 t C ha -1 par an. Des études sur les changements en C minéral du sol sur une A/R arbustive de prairies suggèrent des pertes mineures, qui seraient apparemment largement compensées par une accumulation dans la litière et dans la couche d'humus.

“…The destructive sampling method is accurate but time consuming and not always applicable (e.g., in protected areas - Gratani et al 1980). Most used methods are based on allometric equations relating AGB to its proxies, such as the shrub height (Gratani et al 1980, Sternberg & Shoshany 2001, Bianchi et al 2002, Coomes et al 2002, Scarton et al 2002, Corona et al 2011b or the crown diameter (Gratani et al 1980, Lledò et al 1992, Quideau et al 1998, Sternberg & Shoshany 2001, Coomes et al 2002, Ogaya et al 2003, De Luis et al 2004, Saglam et al 2008, Corona et al 2011a). Gratani et al (1980) estimated the apparent volume (AV) from the crown diameter and height measurements, while Catarino et al (1982) used plant height and stem diameter measurements.…”

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.
