That's partly because Government efforts to create a carbon market through the emissions trading scheme have flopped, giving plantation owners little incentive to make carbon capture a priority. It's also a result of the 30-year wait between planting trees for which they have paid a premium price and pocketing the expected higher profits.
"If you compare it with annual crops, it's much easier to sell the idea of genetic improvement because you get a more immediate return."
The upshot is that high carbon absorption is not of itself a goal of the breeding programme, Carson says.
"We can't afford to make it a major focus but fortunately it happens to coincide with those other goals.
"It would certainly make a big difference to our company and a lot of others if the message about the need for more afforestation, both for reasons of controlling climate change and, more importantly, for erosion control and water quality, was got through by a pricing mechanism."
Forest Genetics supplies about 2.5 million of the 55-60 million seedlings planted each year in New Zealand. At up to $720 for 1000 seedlings, they're more than twice the price of the least genetically improved seedlings on the market.
The company's aim of improving its stock at a faster rate than the overall breeding population will be significantly boosted by the R&D grant, Carson says. "We need to get more large companies to take the step into clonal forestry. In order to do that we need to maintain the research effort and keep our product improving."
