Do we know
our place…?
Stop planting filthy pinus radiata trees
A Community View?
Is there any more obscene sight than hectares of good farmland disappearing into
pinus radiata, or recently harvested land? The majority of trees are foreign owned
while we supply the land and a predominantly low-wage employment role.
Forestry of little value.
Have you ever seen an attractive and inspiring forestry town? There isn’t one!
Wednesday, March 06, 2013
If you are around 10 years and older, then hold on to your memories of Gisborne, the
Poverty Bay region and the East Coast: the soul and character, image and “feel” of
this great region is steadily being lost to the gross impact of the forestry industry,
grower of the filthy pinus radiata tree.
This industry did not get going on its own in a commercial world: it got incentives
post-Cyclone Bola and, more recently, the nonsense of the ETS scheme.
Erosion / debris problems are a
“forestry problem”
Pastoral erosion is “bad luck”
Ecosystem service provision – a
subsidy to forestry….
or
a compensation for opportunity
lost to agriculture?
Has NZ Learnt
it’s lessons…?
An Official View….!
Good farmland ..AND ..why we are not going to plant!

Not bad for an industry that
struggles for a place at the table!

In 2009 – 2010 forestry was the
third largest contributor to GDP
growth behind “Wholesale trade”
and “Transport and storage”.
The Science Challenge
At a time when NZ Inc desperately needs to strengthen its balance sheet and ensure capital is used productively we
have many millions of hectare “underemployed”, debt poorly allocated and environmental consequences arising
from lack “free capital flows” as production is maximised to extract “land value”
Recent Science challenge – “enhance p0
Productivity while maintaining land and
water Quality.
We have 10.mill ha of land under –
performing. Perhaps we start here?!!
Fundamental Science.
Economics.
Societal understanding.
Political process
Improved economic AND
environmental performance.
Many fundamentals
well known – for decades!
Marriage of economics
and biological sciences.
We need science to “join
the dots” & paint the
“Big Pictures.”
Provide spatial and
temporal context for
society.
Bringing it together…
Spatial Economics
Land at current
values. Pastoral ROI
of approx 1.5%.
Land available for
forestry @ 8% = 0%
Land value imputed
@ 8% RoI.
Land available for
forestry = 44%
Napier
Spatial Economics
What if we also hedge
NZ carbon liabilities
@ $10 - current land
values & RoI….
Forests = 2.5%
Hedge NZ carbon
liabilities @ $10 and
land values reflect
farming @ 8% RoI…
Forests = 60%
So what what else…?
Environmental Services
What else do the public get out of this?
Water Quality
If sediment yield is at least in part a
surrogate for water quality – NZEEM
suggests forests produce less sediment
most of the time.
If avoided erosion means less sediment
where does that leave forests
FORESTS DO HAVE IT!
Well established base that
plantation forests can harbour
important species.
Can maintain good biodiversity
an ecosystem service.
Spatial dimension now present.
How will it play out for the
service provisioner v.s the service
consumer?

us that
plantation

devoid of
biodiversity.

The future?... Dynamic landscape scale assessment
and modeling of biodiversity.
•
•
•
•
What richness and diversity can we expect between
forest species?
How does biodiversity change over the cycle of
management of a large plantation?
Are coupe sizes relevant?
How do plantations perform as buffers and
connectors?
Hazardous
Landscapes
Forestry not without its problem
areas.
Tools for Hazard ID
Shallow landslide hazard models.
•
Looking promising.
•
Tool for harvest planning and
afforestation?
•
Plus Melton’s ratio… tool for
downstream hazard
management
Other Forestry
Models
Meltons rations between 0.63 – 0.86.
Debris flows a distinct hazard!
What can we do in these situations?
Whose in the wrong place??
The forest…?
The subdivision….?
Will “inappropriate subdivision and
development” be better managed also.
_________________________________
Ultimately big issues over….
•
Who gains and who looses?
•
How do you make it transparent ?
•
What are the right species and
patterns at local and landscape
scales?
•
Can ecosystem services cover the
sunk costs of other species – in the
right place.?
•
Are there other forestry models?
Integrative Science
We can see there are significant
problems and questions arising from
the examples used.
Current economic constructs may not
be giving NZ a good deal from its 10
million ha of rural land!
•
Our economic performance is
poor.
•
Our environmental performance
is poor.
How do we as a nation integrate all
the competing pressures to deliver the
best results for investors,
communities, the environment and
NZ Inc?
How de we demonstrate results,
implications, cause and effect to
improve acceptance and adoption?
A role for multi-objective, multidimensional problem solving?
