Dogs and drones join forest battle against eight-toothed beetle

It is smaller than your nails, but this hairy beetle is one of the biggest single hazards for the UK forests.

The bark Beetle has been a crisis of Europe, causing millions of spruce trees to die, yet the government thought that it could spread to the UK by examining the wood products imported at the ports.

But this was not the entry path of his choice – he was being taken directly to the English channel to the winds.

Now, scientists of the UK government are fighting back, including an unusual arsenal, including sniper dogs, drones and nuclear waste models.

They claim that Britain has erased Beetle from risky areas in East and Southeast. But climate change can make the work even more difficult.

The spruce bark beetle, or IPS typographs, has been making its way through Europe’s conifer trees for decades, leaving the mark of destruction behind.

The beetle rear and their youngsters feed from under the bark of spruce trees, which are in the complex webs of interviewing tunnels called gallery.

When trees are infected with a few thousand beetles, they can withstand using the resin to remove the beef.

But for a stressed tree, its natural defense decreases and beetle starts to multiply.

The head of Tree Health in Forest Research funded by the Government of UK, Dr. “Their population can be formed at a point where they can overcome the rescue of the tree – millions, billions of beetles.”

“Many trees cannot deal with them, especially when it is dry, they do not have resin pressure to flush the galleries.”

Since Betal caught in Norway a decade ago, it is capable of erasing 100 million cubic meters of spruce, According to Rowathsted Research.

As the Sitaka spruce is the main tree used for wood in the UK, Dr. Blake and his colleagues saw development with some serious concern over the continental Europe.

In Forestry Research, Andrea Deol said, “We have 725,000 hectares of spruce, if this beetle was allowed to hold on it, devastating capacity means a large amount of risk.” “We gave importance to it – and it is a partial assessment in Great Britain at £ 2.9bn per year.”

There are more than 1,400 pests and diseases on the government’s plant health risk register, but the IP is labeled “Public Enemy Number One”.

According to Nick Philips at the Charity the Woodland Trust, the number of diseases has increased.

“Mainly, the reason for this is global trade, we are importing trees for wood products, planting, which sometimes bring ‘hiccups’ in terms of pests and illness,” he said.

Forestry Research was working with boundary control over years to check such products for IPS, but in 2018 made a shocking discovery in a wood at Kent.

“We got a breeding population that was there for a few years,” Ms. Deol explained.

“Later we started raising big versions of Beetle [our] The nets that suggested that they were reaching through other mediums. Now all the researches we have done have indicated that they are being blown from the continent on the air, “he said.

The team knew that they had to work quickly and deploy a mixture of techniques that would not be seen out of place in a military campaign.

The drone is sent to survey hundreds of hectares of forest, in search of signs of transition from the sky – as the beetle holds, the upper canal of the tree cannot be fed nutrients and water, and starts dying.

But further to inspect the trees, it is a laborious work of the ongoing antomologists.

Andrea Deol said, “They are looking for a needle in a histor, sometimes looking for single beetle – before they are allowed to install.”

In the same year, his team has inspected 4,500 hectares of spruce on public property – just shy out of 7,000 football pitches.

It is difficult to maintain such physically demanding work and the team is looking for some help equally from the natural and technical world.

When the pioneer spruce bark beetle finds a suitable host tree, they release chemical signals to attract partner beetles to the pheromone – chemical signals and install a colony.

But it is this strong smell, as well as their insects associated with pests – that makes them the ideal found by sniper dogs.

Early tests so far have been successful. Dogs are especially useful for inspecting large wooden piles that can be difficult to observe visually.

The team is also deploying cameras on their bug trap, now capable of scanning daily for Beetle and identifying them in real time.

“We have [created] Our own algorithm to identify insects. We have taken about 20,000 images of IP, other beetles and debris, which have been formally identified by the entomologist, and are fed in the model, “said Dr. Blake.

Some trap can be difficult to reach areas and earlier only every week could be tested by the entomologist by the entomologist.

The result of this work means that the UK has been confirmed as the first country, which has erased IPS typographs in its controlled areas, which is considered at risk from infection, and Which covers South East and Eastern England.

“What we are doing is positively impacting and it is important that we continue to maintain that effort, if we let our guard go down then we know that we have got the risks of those opportunities year after year,” said Mushri Deol.

And those risks are increasing. Europe has seen an increase in the population of IP as they take advantage of trees stressed with changing climate.

Europe is experiencing more extreme rainfall in winter and the milky temperature means less cold, leaving the trees in a state of waterfall.

This coupled with dried summer leaves them stressed and susceptible to fall into the stormy season, and this occurs when the IPS can catch.

The risk of IPS colonies carrying to Britain increases with a large population in Europe.

In Forestry Research, the team is working hard to properly predict when these infiltrations may occur.

“We are modeling with colleagues at the University of Cambridge and Met Office, which has optimized the IPS to the nuclear atmospheric spread model,” Dr. Blake explained. “so, [the model] Originally used to see the atomic decline and where the winds take it, instead we are using the model to see how far the IPS goes. ,

Nick Philips in the Woodland Trust strongly supports the government’s work, but worrys about the loss of ancient woodland – the oldest and most biologically rich regions of the forest.

The commercial spruce has long been planted next to such wood, and every time a tree hosting the spruce beetle is found, it and the neighbor, sometimes ancient trees have to be removed.

He said, “We really want the government to maintain as much trees as they can, especially those who are not affected, and then when the trees are removed, support the landowners to support the landowners what it is,” he said. “So that they are given grants, for example, to be able to recover woodland sites.”

The government has increased funds for Woodlands in recent years, but it has focused on planting new trees.

“If we only have wealth and support for the first few years of life of a tree, but not for Woodlands that are 100 or century ages, we are not going to be able to recover nature and capture carbon,” he said.
