| dc.description.abstract | The need to devise the monetary value of the ecological contribution of carbon pools for the
ecosystem increases as there is a limited baseline of immeasurable value of the natural ecosystem. This
study has been undergone to develop ecological tools for assigning forest biomass, necromass, and soil
organic matter to a natural forest ecosystem. Comprehensive analysis and review of many publications,
and reports about ecological valuation, tree appraisals, and any appraisal methods were performed to
determine the parameters of ecological contribution for the appraisal equation. Cost based approach
and simple mathematical methods were used to propose the equations. Three equations for biomass,
necromass, and soil organic matter (SOM) were developed as ecological valuation tools to assign their
ecological values or ecovals (Ѥ). This Ѥ value was the sum of ecological structure (S) and function
(F) values. S value was deducted from the ecological base value of structure (bS) and dimension (D). F
value was derived from the ecological base value of F (bF) and carbon content weight, and additional
parameter of existence factor (Ef) of species or decay class factor for necromass (d). The bS and bF
prices or costs were taken from the national or international standard price/costs in USD currency. The
equations are applicable to appraise the ecological values of any natural ecosystems. People may
obtain information about the worth of the ecoval based on its carbon pool as a reflection of ecosystem
structure and function. The information of ecoval can be used as database or ecological consideration
to generate policy or make a decision for sustainable natural ecosystems. | en_US |
