(New Zealand) – Deforestation intentions have soared as the emissions trading scheme, at least at current rock-bottom prices, is no longer seen as a barrier to switching to other land uses.
A survey of large forest owners (with over 10,000 hectares) by Professor Bruce Manley of Canterbury University has found they intend to deforest 39,000ha between now and 2020, mainly in the central North Island and mainly to switch to dairy farming.
They represent three-quarters of the plantation forests with trees older than 20 years, which are likely to be harvested within the next eight years.
Assuming smaller forest owners only replant 80 per cent of the forests they harvest in the same period, the total area deforested would be 55,000ha or 12 per cent of the area of plantation forest maturing in that period.
On an annual basis it would represent only a modest increase on deforestation over the past five years - the period of the Kyoto Protocol's first commitment period, through which forest owners have had liabilities under the ETS.
But it represents a steep increase in the amount of deforestation the large forest owners said they expected to do in Manley's previous survey in 2011 on the assumption that the ETS would remain in place.
That survey indicated that their expected total deforestation between 2008 and 2020 would be just 17,000ha, not the 62,000ha recorded in the latest survey.
Instead it is closer to the 58,000ha of deforestation they said then that they would do if there was no ETS. [more]
