Categories of natural woody vegetation and of plantations, and volume concepts used are indicated by symbols in the tables and corresponding comments of each country brief. They are explained in detail in chapter II of part I of this report. Their simplified definition is recalled below.
Natural woody vegetation
|NHCf1uv||:||undisturbed productive closed broadleaved forests not (intensively) managed;|
|NHCf1uc||:||logged-over productive closed broadleaved forests not (intensively) managed;|
|NHCf1u||:||productive closed broadleaved forests not (intensively) managed;|
|NHCf1m||:||(intensively) managed productive closed broadleaved forests;|
|NHCf1||:||productive closed broadleaved forests;|
|NHCf2i||:||closed broadleaved forests unproductive for physical reasons (stand and terrain characteristics);|
|NHCf2r||:||closed broadleaved forests unproductive for legal reasons;|
|NHCf2||:||unproductive closed broadleaved forests;|
|NHCf||:||closed broadleaved forests;|
|NHCa||:||forest fallow (of closed broadleaved forests).|
Equivalent categories of coniferous, bamboo and closed forests (all together) have similar symbols in which NHC is replaced by NS, NHB and N. respectively.
|NHc/NHO1||:||productive mixed broadleaved forest-grassland tree formations;|
|NHc/NHO2i||:||mixed broadleaved forest-grassland tree formations unproductive for physical reasons (stand and terrain characteristics);|
|NHc/NHO2r||:||mixed broadleaved forest-grassland tree formations unproductive for legal reasons;|
|NHc/NHO2||:||unproductive mixed broadleaved forest-grassland tree formations;|
|NHc/NHO||:||mixed broadleaved forest-grassland tree formations;|
|NHc/NHOa||:||forest fallow (of mixed broadleaved forest-grassland tree formations);|
|nH||:||(essentially) shrub formations (broadleaved).|
|-||PHL1:||industrial plantations of hardwood species other than fast-growing ones;|
|PHH1:||industrial plantations of fast-growing hardwood species;|
|PH.1:||industrial hardwood plantations;|
|PS.1:||industrial softwood plantations;|
|-||PHL2:||non-industrial plantations of hardwood species other than fast-growing ones;|
|PHH2:||non-industrial plantations of fast-growing hardwood species;|
|PH.2:||non-industrial hardwood plantations;|
|PS.2:||non-industrial softwood plantations;|
|-||PHL||=||PHL1+PHL2:||plantations of hardwood species other than fast-growing ones;|
|PHH||=||PHH1+PHH2:||plantations of fast-growing hardwood species;|
Concepts of volume
|-||VOB:||gross volume over bark of free bole (from stump or buttresses to crown point or first main branch) of all living trees more than 10 cm diameter at breast height (or above buttresses if they are higher);|
|-||VAC:||(for forest not intensively managed): volume actually commercialized, that is volume under bark of logs actually extracted from the forest;|
|-||AAC:||(for intensively managed forests): gross annual allowable cut, in general equated with current annual yield.|
N.B. In area tables, the symbol “ε” (greek letter epsilon) is used to indicate negligible or relatively small areas.
