SUBMISSIONS have now closed on a potential law change that would shift the emphasis from fast growing pine and other exotic forests to permanent native forests to absorb our emissions. These are complex debates involving forest ecology, economics, as well as ideology. The decision will have a major impact on long-term land use, especially with regard to marginal farmland. This, in turn, will affect farmer and Mâori landowner decisions on how to maximise returns from their land.
