Strategic criteria for compensating Natura areas
Allan Sims, Allar Padari
Forest produces different goods
• In addition to management goods, a forest contains and helps to:– clear water – clear air– protect against erosion– protect shore and coast– old trees– habitats for
• birds• animals• rare plants
– recreation areas– etc.
Compensation
• Management restrictions in Natura areas do not allow forest owners to get a profit as much as in unrestricted forest
• Compensation is necessary to support forest owners for producing public goods
• In addition to management goods, there exists Natura areas for people are willing to pay
Forest and its owner
• The forest owner gets compensation in managed forest through management profit for producing public goods
• In restricted forest the owner produce public goods by own costs, if there exists no compensation
COMPENSATIONCurrent method
Method for compensation
– The forest owner gets: • 110 €/ha, if forest area is strictly protected or • 60 €/ha for other protected forest area
Properties of the method
Disadvantage
• Forest areas have different values, but the method does not consider that
Advantage
• Simple to use
COMPENSATIONProposal
Method for compensation
– Method should consider compensation value through forest value:
• Compensation value should be calculated as predictable profit from forest.
Profit calculation
• Profit depends on site productivity:
– Forest site type, which shows potential tree species for the site
– Site index, which shows wood productivity for the site
Profit calculation
• Forest productivity is calculated by long term forest growth simulation, where:– stand mean height,– stand mean diameter,– stand age,– stand volume and– density
• are used.
Profit calculation
• Forest growth is simulated with mathematical growth equations with one year steps
• In simulation for every year is considered thinning necessity and applied if „needed“.
• Growth is simulated until final felling
Profit calculation
• After simulation it is calculated sum of timber assortments from thinnings and final felling
• All assortments are divided into total growth period
• Thus, we can find potential forest productivity for the site
Profit calculation
• Income is calculated by multiplying assortments values with amount of assortments (e.g. RMK mean values)
• Outcome is expenses for felling and forest regeneration
• A result is mean profit per year, which is mean annual money damage for a forest owner
Profit calculation
• According to this method, money damage range is 0 – 220 €/ha.
• Thus, for some forest owners, who's forests are in fertile areas, the compensation differences are big.
• Proposed method is simple to use, because forest inventory data are available and it is on matter of calculation
Forest produces different goods
• In addition to management goods, a forest contains and helps to:– clear water – clear air– protect against erosion– protect shore and coast– old trees– habitats for
• birds• animals• rare plants
– recreation areas– etc.
Summary
• Natura areas have values and there are willing to pay
• Forest owners should not have money damages for owning such forest
• Today exists the method to compensate, but it is inflexible and does not consider site productivity
• A compensation method should be more an owner frendly and it is quite simple to apply
