NFI-Definition
     – including temporarily unstocked areas
     – excluding permanently non-wooded ground
     – not including minimum parameters for crown cover, area and height as requested in the
       Marrakech accords


     needs to be complemented!
Area of ground covered by forest vegetation, irrespective of the information in the cadastral survey or similar
records. The term forest also refers to cutover or thinned areas, forest tracks, firebreaks, openings and
clearings, forest glades, feeding grounds for game, landings, rides located in the forest, further areas linked to
and serving the forest including areas with recreation facilities, overgrown heaths and moorland, overgrown
former pastures, alpine pastures and rough pastures, as well as areas of dwarf pines and green alders.
Heaths, moorland, pastures, alpine pastures and rough pastures are considered to be overgrown if the natural
forest cover has reached an average age of five years and if at least 50% of the area is covered by forest.
Areas with forest cover in open pasture land or in built-up areas of under 1000 m², coppices under 10 m wide
and the cultivation of Christmas trees and ornamental brushwood as well as parkland attached to country
houses are not forest within the meaning of the NFI. Watercourses up to 5 m wide do not break the continuity
of a forest area.

•   NFI
     –   ground based sample survey
     –   approximately 50.000 permanently marked samples
     –   evaluation of tree-, stand-, an other parameters
     –   first in 1987 (former states)
     –   second in 2002 (incl. new states)
     –   information about growth, yield and changes

•   Forest soil inventory
     –   ground based sample survey
     –   approximately 1800 samples
     –   evaluation of litter-, soil-, and (stand) parameters
     –   first in 1990’s
     –   second in 2007-09
     –   information about soil conditions and changes

     Stock change method for all pools planned (starting up from 2008/2012)

Only for biomass implemented

•   on tree level by species
    ZELL (2005)

•   aboveground
     – BEF (Volume)
        after GRUNDNER & SCHWAPPACH (1952)
     – conversion to dry mass with density by compartments
        after KOLLMANN (1982), HAKKILA (1972)

•   belowground
     – root shoot ratio
        after DIETER & ELSASSER (2002)

•   uncertainty estimation under discussion (example follows)
