In terms of carbon sequestration over time the discussion shouldn't be just about radiata vs indigenous, but exotic vs indigenous. There are a range of exotic species that sequester carbon at comparable rates to radiata while also providing high value timber and income streams. It's misleading to present radiata pine as the only plantation species that does the job.

Agreed, Dean. It would be good to see a wider range of exotic species planted besides radiata pine. We would have to be careful to avoid wildings, and so placement of wilding-prone species such as Douglas fir would have to be judicious.

This is a good video.

If people are interested in why the ETS is irrational in its treatment of forestry, consider:

  1. The ETS is a cap and trade system, but any forest-based credits potentially increase the cap and so the total amount of pollution is poorly controlled.
  2. The concept of "greenhouse gas neutrality" is misunderstood and misused in a cap and trade scheme where credits are grandfathered for "allowed" pollution to trade-exposed industries or (potentially) farming.
