“…Noteworthy, in recent years laser scanning (and, namely, airborne laser scanning, henceforth referred to as ALS) is increasingly being applied to support forest inventories, providing assessment of the height of upper canopy for the surveyed area. A close relationship has been proven between the timber volume (or standing biomass) in inventory plots and the canopy height from ALS surveys (Naesset 2002, 2004, Parker & Evans 2004, Corona & Fattorini 2008, Gregoire et al 2011, Corona et al 2012b. Obviously, this relationship should hold irrespective of the fact that plots can be reached in the field or not.…”

The aim of this paper is to give an overview of some recent proposals to support national forest inventories. The reviewed literature is strictly of design- based nature, i.e., uncertainty only stems from the sampling scheme actually adopted in the survey, rather than being assumed or modeled as in model- based approaches. National forest inventories are viewed as two-phase sample surveys to estimate at the same occasion the extent of the continuous population of points constituting the forest cover and the total of a forest attribute (e.g., volume or biomass) in the discrete population of trees for several forest types and/or administrative districts. The first phase is performed from remote sensing imagery while the second phase is performed on the field, possibly adopting the information acquired in the first phase as auxiliary information. A novel methodology is adopted based on Monte Carlo integration methods, which leads to a very general estimation strategy. Some recent proposals are considered in which remote sensing information acquired in the first phase is used to assess some physical characteristics of non-forest resources, such as woodlots, tree-rows and isolated trees outside the forest without additional field work. Finally, a new proposal is discussed in which canopy height from laser scanning is adopted as auxiliary information to recover missing data occurring when some sampled points cannot be reached because of hazardous terrain

“…Ad esempio, nell'ambito del progetto "Alforlab" (PON03PE 00024 1 -http:// www.alforlab.it/) sono stati messi a punto modelli di predizione della massa legnosa basati su dati ALS per tutte le principali formazioni forestali della Calabria (Scrinzi et al 2017). Varie ricerche svolte in Italia hanno evidenziato la capacità dei dati ALS di produrre stime accurate dei principali parametri dendrometrici a supporto della pianificazione forestale a livello aziendale , Corona et al 2012, 2014, Pirotti et al 2012, 2017) e anche per la stessa delineazione della copertura boschiva in funzione di altezza minima degli alberi, grado di copertura arborea, superficie e larghezza minima (Alivernini et al 2016). Nella Tenuta Presidenziale di Castelporziano il Sistema Informativo forestale (SIF-TEC) in uso dal 2015 è stato corredato da dati di volume legnoso e fitomasse, sia in continuo che per singolo popolamento (Scrinzi & Clementel 2015b, Colle 2015.…”

IntroduzioneNegli ultimi decenni è avvenuta una profonda trasformazione del settore forestale italiano, in linea con quanto osservato anche a livello europeo (MI-PAAF 2015). Il sorgere di nuove funzioni e ruoli produttivi e sociali attribuiti alle risorse forestali (sensu lato, incluse le aree verdi in ambito urbano, le piantagioni da legno e gli alberi fuori-foresta) hanno determinato una crescita dell'importanza, ma anche della complessità del sistema foresta-legno. In Italia esiste una significativa tradizione nella ricerca forestale e una radicata consapevolezza che l'innovazione e la competitività sono possibili grazie a un'alleanza tra iniziative di ricerca strategiche a scala nazionale con Abstract: Precision forestry: concepts, tools and perspectives in Italy.Recent advancements in informatics and communication technologies have led to an increasing employment of analytical and communication tools in forestry, including data from satellite, airborne, unmanned aerial vehichles, global positioning systems, and many sensors, devices and other geospatial tools. Precision forestry enables highly repeatable measurements, actions and processes to manage and harvest forest stands, simultaneously allowing information linkages between production and wood supply chain, involving resource managers and environmental community; all these factors are contributing to the wider goal of sustainable forest management. In this report, we review the most recent advances in the precision forestry applications and tools, with particular reference on advanced forest inventory, decision support systems, precision forest harvesting, and wood traceability. We discuss the opportunities and challenges towards implementing precision forest practices in forest management and planning and forest industry in Italy.

“…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.
