The South East has been declared a “low priority” area – authorities say that because the disease is already widespread, it is not cost effective to tackle it.

Dr Alun Griffiths, microbiologist and chairman of the Kent Men of the Trees conservation charity, said the county needed better protection.

“I’ve been studying diseases around the world all my professional life,” he said.

“I’ve always thought that if you have a focus, an area where disease is being spread rapidly, that would be the place where you’d put most of your effort.

The government is planting thousands of young ash trees in the region as part of a research trial, including at the Hucking Estate near Maidstone.

Scientists hope 1% of them may survive and develop resistance in a decade’s time.

  • Developing resistance to the disease in the native ash tree population
  • Encouraging landowner, citizen and industry engagement in surveillance, monitoring and action in tackling the problem

Defra said it is planting 250,000 ash saplings in the east and south east so Defra scientists and the Forestry Commission and local landowners can monitor the trees for signs of Chalara, paying particular attention to any signs of resistance.

Comment: It is crazy to spend all the money planting out nursery reared seedlings, when natural woodlands can do a much better job themselves for free, with woodland saplings benefiting from their ancient mycorrhizal support systems.

Landowners in England will be paid to remove young ash trees and replace them with other species to help slow the spread of the disease killing them, the environment secretary said on Tuesday.

Paterson said: “We know we can’t stop Chalara fraxinea infecting our ash trees, so we have to throw our resources into managing it and slowing the spread. A key part of that strategy will be identifying those trees which have a natural resistance to the disease so that we can restock our woodlands in the future.”

The amount the government will spend on replacing young trees will depend on demand, said a spokeswoman. Landowners will be paid to remove recently planted ash from high priority areas – a band running from Cornwall and Devon and then north through Gloucester and up to the Midlands – and replace the trees with other species.

The government is to plant a quarter of a million ash trees in an attempt to find strains that are resistant to the fungus responsible for ash dieback.

The £1.5m project is part of the long term management plan, unveiled by the Environment Secretary Owen Paterson.

Funding will also be made available to woodland owners to help them remove infected ash saplings.

Ash dieback has been been found in a sapling on private land in Somerset, Defra has confirmed.

It has since been destroyed to prevent any contamination.

Defra said the infected sapling would have been carried in as part of a batch and planted, rather being infected with airborne spores.

Defra said it would be “very, very bad luck” for the disease to have spread in the short time it was in the county.

The seedlings that were placed into the ground came from generations of backcross breeding that date to the early 1980s. Matt Brinckman, the American Chestnut Foundation’s Mid-Atlantic Regional Science Coordinator, said the project began by crossing an American chestnut with a Chinese chestnut, which is resistant to the blight. The hybrids that were in turn resistant to the blight were crossed again with American chestnut — and again and again until scientists obtained a crossbreed that was 15/16 American chestnut and only 1/16 Chinese chestnut.

The American Chestnut Cooperators’ Foundation was co-founded by Gary Griffin, a plant pathologist at Virginia Tech. Instead of crossbreeding, that group has focused on finding the few remaining large American chestnut trees that have demonstrated partial blight resistance.

“We try to interbreed those to obtain greater levels of blight control,” Griffin said. “There aren’t many of these specimens, but we’ve found them and have been working with them for more than 30 years.”

I find I am, to some extent, on a similar wavelength to Andy Byfield in his Guardian piece on tree planting.

But, I do remain a little more optimistic about the role that planting new native trees and woods can play. Tree planting is usually a very visible activity and one which can be used as a way of engaging and enthusing people about the natural environment, whilst the wider work of protecting our valuable ancient woods and the major programmes of restoring ancient woods that were damaged by conifer planting in recent times continues too, day in and day out.

I for one would be more than happy to see a strong welcome for the Panel’s recommendations on a major increase in woodland expansion being set clearly in the context of the Natural Environment White Paper.
