Background: Estimation of forest biomass on the regional and global scale is of great importance. Many studies have demonstrated that lidar is an accurate tool for estimating forest aboveground biomass. However, results vary with forest types, terrain conditions and the quality of the lidar data. Methods: In this study, we investigated the utility of low density lidar data (<2 points•m −2 ) for estimating forest aboveground biomass in the mountainous forests of northern Italy. As a study site we selected a 4 km 2 area in the Valsassina mountains in Lombardy Region. The site is characterized by mixed and broad-leaved forests with variable stand densities and tree species compositions, being representative for the entire Pre-Alps region in terms of type of forest and geomorphology. We measured and determined tree height, DBH and tree species for 27 randomly located circular plots (radius =10 m) in May 2008. We used allometric equations to calculate total aboveground tree biomass and subsequently plot-level aboveground biomass (mg•ha Conclusions: Low-density lidar data can be used to develop a forest aboveground biomass model from plot-level lidar height measurements with acceptable accuracies. In order to monitoring the National Forest Inventory, and respond to Kyoto protocol requirements, this analysis might be applied to a larger area.

“…DBH appeared to be the best predictor of root system biomass and biomass increment, as is commonly found for the biomass of aerial tree compartments [2,14,16,25,32,37] and also for the few studies dealing with root systems [9,30]. Generally, linear relationships can be adjusted after a two-sided logarithmic transformation [2,4,30,35].…”

-This study is part of a larger project aimed at quantifying the biomass and biomass increment of an experimental beech stand aged 30 years, and comparing the carbon sequestration in trees to carbon fluxes. The below ground part of trees is expected to play an important role in carbon sequestration. A method has been developed to estimate the biomass and biomass increment of coarse, small and fine roots of trees from root system excavations of sampled trees of different crown classes. The biomass and biomass increment of broken root ends during excavation was estimated from the diameter of the roots at the broken points. Equations were then established relating the biomass and biomass increment of the different root categories to tree DBH. These equations were then used to estimate the root biomass and biomass increment of the experimental stand from stem inventory, for the different root categories. Trees from dominant and codominant crown classes contribute for more than 80% to below ground biomass and biomass increment of the stand. root system / biomass / biomass increment / biomass distribution / Fagus sylvatica Résumé -Biomasse et accroissement en biomasse du système racinaire dans un peuplement de hêtre du Nord-Est de la France. Cette étude fait partie d'un projet plus vaste ayant pour objectif l'estimation de la biomasse aérienne et souterraine d'un peuplement expérimental de hêtre de 30 ans et de son accroissement, pour comparer la quantité de carbone séquestrée annuellement dans les arbres aux flux de carbone mesurés par les échanges gazeux. La partie souterraine des arbres paraît jouer un rôle important dans la séquestration du carbone. Une méthode a été développée pour estimer la biomasse et l'accroissement en biomasse des racines de différentes catégories de grosseur grâce à l'extraction du sol de systèmes racinaires d'un échantillon d'arbres représentatif des diffé-rentes classes de statut social du peuplement. La biomasse et l'accroissement en biomasse des parties de racines cassées lors de l'extraction du sol ont pu être estimés, pour chaque catégorie de racine, à partir du diamètre des racines au niveau de la cassure. Des relations ont ensuite été établies entre la biomasse racinaire et son accroissement, pour chaque catégorie de racines, et le diamètre de l'arbre à 1,30 m. Ces équations ont été utilisées pour estimer les biomasses au niveau du peuplement à partir de l'inventaire des arbres. Les arbres dominants et codominants du peuplement contribuent pour plus de 80 % à la biomasse souterraine du peuplement et à son accroissement. système racinaire / biomasse / accroissement de la biomasse / répartition de la biomasse / Fagus sylvatica

“…Morphological and anatomical measurements were carried out in YC and OC, to point out differences between the different ages [16,35]. Morphological leaf traits were analysed on 50 fully expanded leaves ( The following parameters were measured: projected leaf surface area (excluding petiole) (LSA, cm 2 ), obtained by the Image Analysis System (Delta-T Devices, UK); leaf dry mass (LDM, mg), determined drying at 80 °C to constant mass.…”

-Coppices of Castanea sativa Miller (1,5,7,10,12,17,23,26, and 30 years old stands) were investigated. Total basal area (BA) ranged from 4.9 ± 1.9 m 2 ha -1 (1 year old stands) to 41.0 ± 2.3 m 2 ha -1 (30 years old stands), and Leaf Area Index (LAI) from 0.18 ± 0.08 m 2 m -2 (1 year old stands) to 5.00 ± 0.22 m 2 m -2 (12 years old stands). Morphological and physiological leaf traits were analysed in 5 (YC) and 23 years old stands (OC) to point out the functional responses to clearing impact. The results pointed out the high productivity of C. sativa in the Park, due to favourable climatic and soil conditions. Significant differences of morpho-physiological leaf traits between YC and OC stands were observed during the last period of the vegetative cycle; it could be due to the higher efficiency in resource use of YC leaves than OC.
