Timber Biodiversity Recreation

TIMBERPROFUSION

Available forest land is managed primarily fortimber production while other services aretreated as secondary. Timber supply is very highto the point of substantially going beyond thedemand. The supply of biodiversity associatedwith production-oriented forests is low. Undersuch circumstances some recreation isprovided, but it does notmeet demand.

0.6 -0.5 -0.1

ENVIRONMENTALEDEN

A large proportion of the forest land is managedwith nature conservation as a primary objective.Supply of timber does not meet demand, whilebiodiversity is oversupplied. Recreation, beingpartly associated with levels of biodiversity, isalso supplied slightly beyond the demand.

-0.2 0.5 0.1

PERFECTEQUILIBRIUM

Forest land management seeks multi-functionality. Production levels of all threeservices are equal, but they do not meet thedemand.
