Within the framework of Action B9 of the project LIFE FutureForCoppiceS, this document provides guidelines on how to approach cross-cutting issues such as field sampling, Quality Assurance procedures, and data organization. (i) Field sampling is addressed taking into account practical (different size of the project areas; specific needs of individual investigations) as well as financial constraints.

Each macroplot is divided into a core area (the inner 15x30 m portion of the macroplot) and a buffer zone (the outer portion of the macroplot, 2.5 m width all around the core area). Most of measurements will take place in the core area (e.g. vegetation survey), on the entire macroplot (e.g. tree condition), on the buffer zone (soil survey), or on the forest district at large (e.g. socio-economic surveys). Probabilistic sampling (different schemes allowed for different investigations) represents the first option of the project.

Nell’ambito dell’Azione B9 del progetto FutureForCoppiceS, questo documento fornisce linee guida per argomenti di interesse generale ai fini della buona riuscita del progetto: campionamento in campagna, procedure di assicurazione di qualità, organizzazione dei dati. (i) Il campionamento è stato considerato tenendo in conto sia aspetti pratici (diverse dimensioni delle aree del progetto; necessità specifiche delle varie indagini) sia finanziari. Come approccio generale, viene selezionato in maniera casuale un macroplot di 800 m2 entro ciascuna area del progetto (n=45). Ogni macroplot è diviso in una core area (la porzione interna di 15x30 m) e la zona tampone (la porzione esterna, larga 2.5 m, intorno alla core area). La maggior parte delle misurazioni viene svolta nella core area (es. vegetazione), sull’intero macroplot (es. condizione degli alberi), nella zona tampone (suolo), o sull’intero distretto forestale (es. aspetti socio-economici). Il campionamento probabilistico (con schemi diversi a seconda dell’indagine) rappresenta la prima opzione del progetto. Nel caso del suolo, tuttavia, questo non è stato ritenuto efficiente, ed è stato proposto un campionamento intenzionale. (ii) L’assicurazione di qualità (QA, Quality Assurance) verrà affrontata principalmente attraverso una serie di procedure operative standard (SOPs), la cui struttura è stata predisposta in modo da essere coerente con i manuali (ICP Forests) adottati per il monitoraggio delle foreste in Europa. (iii) Organizzazione dei dati. La struttura del database tiene conto delle tipiche necessità connesse ad un database relazionale e permette differenti livelli di indagine (dal distretto forestale alla foglia), annidati l’uno entro l’altro, di essere considerati in maniera coerente.

Abstract
Within the framework of Action B9 of the project LIFE FutureForCoppiceS, this document provides guidelines on how to approach cross-cutting issues such as field sampling, Quality Assurance procedures, and data organization. (i) Field sampling is addressed taking into account practical (different size of the project areas; specific needs of individual investigations) as well as financial constraints. As a general approach, one macroplot of 800 m2 is randomly selected within each project area (n=45). Each macroplot is divided into a core area (the inner 15x30 m portion of the macroplot) and a buffer zone (the outer portion of the macroplot, 2.5 m width all around the core area). Most of measurements will take place in the core area (e.g. vegetation survey), on the entire macroplot (e.g. tree condition), on the buffer zone (soil survey), or on the forest district at large (e.g. socio-economic surveys). Probabilistic sampling (different schemes allowed for different investigations) represents the first option of the project. In the case of soil, however, this was reported to be not effective, and a judgemental sampling approach was suggested. (ii) Quality Assurance will be mostly addressed by a series of standard operating procedures, whose structure has been designed to be fully consistent with manuals (ICP Forests) used in international forest monitoring. (iii) Data organization. Database structure has been considered to account for the inherent needs of a relational database, and to allow different, nested level of investigation (from forest district to leaf level) to be consistently taken into account.File | Dimensione | Formato | |
