Forest ecosystems are the most biodiverse and complex habitats. For this reason, it is very important to monitor them specifically. The importance of forest monitoring is recognized from several years, and the most extensive and complete data on the European forest status are given by National Forest Inventories (NFIs).

The LI-BioDiv (ICP Forests) database, derived from the BioSoil-Biodiversity project, is a multi-dimensional forest database that contains records collected in 19 European countries in the period 2005-2008. The database includes information on living trees, deadwood and a ground vegetation survey. The BioSoil-Biodiversity project represents an unique pan-European effort for a standardized multi-dimensional forest diversity monitoring survey, however the LI-BioDiv database is still under-utilized by scientists due to policy restrictions and no depth exploratory analysis of the dataset was carried out until now. Efficient environmental and forest planning require careful assessment and management of big data structure and uncertainty. On the basis of row data: (i) we compared information of standing living trees and deadwood with results of NFIs. Furthermore; (ii) we characterized uncertainty related on ground vegetation data; (iii) we calculated several forest biodiversity indicators analyzing therefore their inter-relationship and their trend over the space and over different forest types and environmental conditions. The results will be useful for achieving satisfactory accuracy of European forest biodiversity estimates, for correctly interpretating the estimates, and for facilitating comparable use of the data.
Il Li-BioDiv database (ICP Forests) che deriva dal progetto BioSoil-Biodiversity, rappresenta un database multidimensionale riguardo alle foreste con dati provenienti da 19 paesi europei, investigati tra il 2005 e il 2008. Tale database contiene informazioni riguardo agli alberi vivi, legno morto e dati riguardo allo strato erbaceo. Il progetto BioSoil-Biodiversity rappresenta l’unica iniziativa di monitoraggio standardizzato multidimesionale della diversità forestale a livello europeo, tuttavia, il Li-BioDiv database risulta essere sottoutilizzato dal mondo scientifico a causa di passate restrizioni di tipo amministrativo-politico e fino ad oggi non sono state effettuate analisi esplorative profonde. Pianificazioni ambientali e forestali efficienti richiedono una valutazione e una gestione attenta della struttura e dell’incertezza legata a grandi moli di dati. Basandoci sui dati grezzi: (i) abbiamo confrontato informazioni derivate dagli alberi vivi e dal legno morto, con i rispettivi dati derivanti dagli inventari nazionali. Inoltre; (ii) abbiamo cercato di caratterizzare l’incertezza relativa ai dati dello strato erbaceo; (iii) abbiamo calcolato indici classici di diversità forestale e analizzato le loro relazioni e i loro trend spaziali nei diversi tipi forestali e in diverse condizioni ambientali. I risultati saranno utili per comprendere con maggiore accuratezza le stime della biodiversità forestale europea, per interpretarle correttamente e per facilitare l’uso dei dati.

Abstract
Forest ecosystems are the most biodiverse and complex habitats. For this reason, it is very important to monitor them specifically. The importance of forest monitoring is recognized from several years, and the most extensive and complete data on the European forest status are given by National Forest Inventories (NFIs). This information concerns trees but usually it marginally considers other ecosystem components such as ground vegetation. The LI-BioDiv (ICP Forests) database, derived from the BioSoil-Biodiversity project, is a multi-dimensional forest database that contains records collected in 19 European countries in the period 2005-2008. The database includes information on living trees, deadwood and a ground vegetation survey. The BioSoil-Biodiversity project represents an unique pan-European effort for a standardized multi-dimensional forest diversity monitoring survey, however the LI-BioDiv database is still under-utilized by scientists due to policy restrictions and no depth exploratory analysis of the dataset was carried out until now. Efficient environmental and forest planning require careful assessment and management of big data structure and uncertainty. On the basis of row data: (i) we compared information of standing living trees and deadwood with results of NFIs. Furthermore; (ii) we characterized uncertainty related on ground vegetation data; (iii) we calculated several forest biodiversity indicators analyzing therefore their inter-relationship and their trend over the space and over different forest types and environmental conditions. The results will be useful for achieving satisfactory accuracy of European forest biodiversity estimates, for correctly interpretating the estimates, and for facilitating comparable use of the data.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
