The everlasting argument

John Purey-Cust Ponders

The everlasting argument, whether to prune or not to prune , depends on you. No one who gives you advice knows any better than you, whatever their experience. They can tell you what is happening now but not to- morrow, not next year, let alone in the lifetime of a forestry rotation – then they are guessing, just like the rest of us.

There is also the difference between the views of the large grower and the small – which introduces another problem, what is ‘small’, but that is an attitude of mind which I won’t attempt to answer. I speak for the small grower.

The large grower, the corporation, most probably deals in a commodity such as Douglas fir or radiate pine where constancy of market flow is usually more important than quality of product. They are price tak- ers, creatures of the moment to whom future trends (of a forestry time length) are irrelevant. They are log exporters. Their advantage is size, which the small grower doesn’t have.

Local saw millers may be an exception. They do re- quire logs of a quality, for instance pruned, that the corporates may no longer produce, so increasingly they must find their own.

Let’s start with radiata pine - should the small grower prune (and thin – the two go together) or not ? Long ago it was argued that to get off the commodity mar- ket radiata pine growers should prune and thin to get the advantage of clear wood and large logs, our inter- national advantage of the time. There was an added advantage in Southland that radiata pine down here is of a relatively low density (or strength), marginal for construction uses whilst it’s clean fresh sawn appear- ance made it an attractive finishing or board grade. The only hazard was a rotation requirement of around 30 years

Those were the halcyon years of the domestic sawmilling industry when it was the big log buyer. There was a premium on pruned and thinned stands of around 20% and on good sites pruning and thinning made sense.

About 10 years ago the radiata market fell on hard times. The domestic market (pruned logs) is still down but the export log trade has perked up. There is very little call for pruned logs and even the rotation length restriction has gone – everything has its price regardless of age, size and quality.

So what to do? Markets remain the same, markets change. Oh dear, we have to think, take a chance. If you read the market report in the February ‘14 Tree Grower you would have known exactly what to do 20 or so years ago if a soothsayer had been there with a crystal ball to tell you – don’t bother pruning. But does it tell you anything of value about the future? Nothing, nothing at all.

Read the early articles on the coming Blenheim con- ference and it’s all about possible changes in wood use which all to me smell clear wood. What if the US market picks up sufficiently to be looking for clear wood again? What if the Chinese market, to save en- ergy and freight costs, switches its wood imports from logs towards sawn lumber and in the process becomes more grade conscious? Stick a note on my tombstone in twenty years time where I’m wrong.

So for the small grower owning radiata my advice would be to prune and thin where you can. You won’t have much market pull anyway, and even less if all you’ve got is the rough stuff. The market may change for the better and they will catch the buyer’s eye. And when to sell? As always, when you need the money.
But should the small grower still plant radiata? I’ll try and get an answer to that later, and pruning other species – later too.


Much can happen between planting and harvesting

Wink Sutton's Blog
Thursday, February 27, 2014

There can be 30 years or more between the decision to establish a plantation and its final harvest. Rarely understood or appreciated are the risks faced by the plantation owner. The plantation may be accidently burned down or suffer wind damage. An insect or pathogen can be introduced which might decrease growth and result in tree malformation or even tree death.

Especially as we now export most of our wood harvest, exchange rates are very important. We are at the mercy of much larger economies and much bigger governments – exchange rates can and do fluctuate. As a small nation we have almost no control over them.

Markets, such as the increasingly dominant export market, may change. Since 1995 Japan has gone from being our largest overseas log buyer to our third most important. China is now our most important market for logs. Our wood exports are increasingly dominated by logs rather than processed wood. The result is that although the plantation harvest has nearly doubled since the mid-1990s, the country’s export earnings after adjusting for inflation have grown at much slower rates than the harvest.

The premiums for quality can also change. None more so than the premiums for pruned radiata logs. In the 1990s there were confident predictions by myself and others that pruned logs would now be worth more than $200 a cubic metre which would be $300 or more adjusted for inflation. Pruned logs now realise less than $150 a cubic metre. As pruning costs money and also reduces tree growth, the price premium for pruned logs hardly justifies pruning with the result that fewer stands are being pruned.

There are also small premiums for unpruned log exports. Export pulp logs in the late 1990s earned about a third per cubic metre as much as unpruned larger logs – currently there is only a very small price premium. I doubt very much if there are any current premiums in overseas markets for older,denser and stiffer wood logs. Will the present price structure continue? Who knows?

Over the life of a rotation there may be 10 or more elections and there will be several changes of government. Financial incentives or disincentives along with taxation policy can and do change. There may also be unforeseen and unpredictable changes in regulations, such as the Emissions Trading Scheme and the Resource Management Act, and trade requirements. An example of the latter would be that all wood must come from certified forests and logs and timber must be free of harmful pathogens.

These are some of the risks faced by plantation owners over a rotation. More importantly they are risks that the plantation owner has almost no control over.
