Scenarios based on NFI11 (data collected 2009-2013)

Scenarios containing roundwood and energy wood removals:
- NT maximum economic removal
- SK maximum sustainable removal
- TH realized cutting removals

Scenario containing only roundwood removal:
- SK_A maximum sustainable roundwood removal

NT : Maximum economic removal

Maximum economic removal scenario defines roundwood and energy wood harvest levels that maximize the net present value without taking into account any sustainability constraints or the demand of wood products. This scenario will harvest all the cutting possibilities as soon as they are feasible for harvesting according to the silvicultural recommendations and which do not fulfill the economic prerequisite (5 % discount rate) for further growing. This scenario defines the maximum short-term economical timber supply.

SK : Maximum sustainable removal

The maximum sustainable removal is defined by maximizing the net present value with 4 % discount rate subject to non-declining periodic total roundwood and energy wood removals, saw log removals and net income. There are no sustainability constraints concerning tree species, cutting methods, age classes or the growth/drain -ratio in order to efficiently utilize the dynamics of forest structure. Energy wood removal can consist of stems, cutting residues, stumps and roots.

TH : Realized cutting removals

Realized cutting removal scenario outlines the development of forest resources if the current (2011-2013) roundwood and energy wood harvesting levels are carried out in the future. In this scenario, the net present value is maximized with 4 % discount rate subject to realized cutting removals by timber assortments. Roundwood removals consist of industrial roundwood and roundwood for households harvested from the area in question. Energy wood removals consist of forest chips for industial heat and power used in the forest centre in question and fuelwood for households. There are no restrictions concerning the removals e.g. by cutting methods, diameter classes or site types. The target constraints are allowed to vary ± 0,5 %.

SK_A : Maximum sustainable roundwood removal

The maximum sustainable roundwood removal is defined by maximizing the net present value with 4 % discount rate subject to non-declining periodic total roundwood removals, saw log removals and net income. There are no sustainability constraints concerning tree species, cutting methods, age classes or the growth/drain -ratio in order to efficiently utilize the dynamics of forest structure.
