Less Carbon Dioxide Absorbed by Amazon as Trees Die Off – Part One

Less Carbon Dioxide Absorbed by Amazon as Trees Die Off

A 30 year study has revealed that the Amazon long absorbed more carbon than it releases and it suggests that the trees and leaves are losing ability to effectively suck up the excess carbon dioxide being pumped into the atmosphere by human activities.

The study shows that Increased mortality rate is the main reason for this with an increase by more than a third since the mid-1980s.

Carbon dioxide is necessary for photosynthesis to take place … the rather cool way that plants convert light into energy.

Oliver Phillips, professor of tropical ecology at the University of Leeds in England and a co-author of the study says that “because they take up a significant amount of our carbon-dioxide emissions. This is a first indication that the process is saturating”.

The Amazon is roughly 15 times the size of California and accounts for at least half the Global tropical Forrest area and with over 300 hundred billion trees store one fifth of all carbon in the earth’s biomass.

Each year, we humans contribute 35 billion tons of CO2 into the atmosphere and while a quarter is thought to be absorbed by the water masses (the oceans), a quarter is absorbed by the forests and trees the remaining half is thought to be the main forces of the man-made climate change.

While the increase in our planets emissions of carbon-dioxide fuelled and surged the growth of the rain forests tress, sadly it has also decreased their life time and increased the trees’ death rate.

Researchers Create Supersized Trees

Just as Ian Morgan Arb storms into another busy few months with a wide range of Arboricultural Training Courses running weekly, Experts at Manchester University think that they have found a way to make the demand for good Arborists even higher.

By Altering two genes to accelerate growth in some trees, experts feel that this finding could help crop production and renewable energy.

A researcher at the University said “This needs to be tested but offers a potential way forward for one of the most pressing challenges of the day.”

PXY and CLE are the genes associated with the growth of cells within the tree trunk. Research found that when overstimulated the trees grew twice as fast, with thicker and wider trunk and more leaves.

With accelerated growth of trees and a boost in biomass energy this research could start to make some headway on the effects of Client Change.

Police inspector retires from force to become tree surgeon

Here at Ian Morgan Arb, we see a wide range of backgrounds represented among our recipients of arborist training in Staffordshire, and one national story has highlighted, once more, how someone from almost any past job can end up entering the field.

The Cumberland & Westmorland Herald reported on how Inspector Dave Willets, of Eden policing, is retiring after some three decades in the police force to become a tree surgeon. The decision to switch career evidently wasn’t one taken lightly by Insp. Willets – he had, after all, dreamed of a career as a police officer since watching Starsky and Hutch on television as a child.

As Insp. Willets himself put it, “When I realised I didn’t have enough brains to be a vet and not enough land to be a farmer, I wanted to be a police officer.”

He went on to enjoy a 14-year stint at the Met in London, after applying to 11 forces around the country while still in his teens. His time in London led to his promotion to sergeant at Chelsea and Kensington, with his specialism being public order offences.

It was during his London career that he was known as police constable three, this being abbreviated to PS3. When it was discovered by colleagues that Insp. Willets was indulging his other passion through evening studies in ecology and conservation at Birkbeck College, University of London, he was nicknamed ‘PS Tree’ – which later became his new business name.

Insp. Willets ‘ journey in arb training can be traced back to 2009, when he completed his initial qualification in tree surgery at Myerscough College, Lancashire. He has lived up north since 1999, when a broken leg sustained in London prompted he and his wife to write down a list of the places where they wanted to live – agreeing on Cumbria.

Although he has spent the last four years based in Penrith, which he has called “fantastic”, on his first move from the capital, he lived in the “stunning” area near Ennerdale Water, commenting: “I had some people asking how I managed with the 20-minute commute, although it was nothing compared to what I used to travel.”

We can only welcome Insp. Willets the very best in his future career here at Ian Morgan Arb. In much the same way, we continually welcome new ambitious enrolees on our own arboricultural training in Staffordshire, the first step into what is a hugely rewarding new professional life for many people of the complete range of backgrounds.


Forwarder overturning incident fortunate not to result in injury

Arb Safety NewsAs a leading provider of arboricultural training, our attention was recently caught by news, as communicated in a Safety Bulletin issued by Scottish Woodlands, of a forwarder overturning, an incident that we are fortunate to report did not cause any injuries.

That is all the more remarkable given that the operator of the machine involved – a Valmet 865 – was not wearing his seat restraint, causing him to fall within the cab, breaking a window in the process. The machine was fitted with double band tracks and was carrying a full load of 3.7m logs when it overturned.

While the machine operator was remarkably unhurt, using the door to leave the cab, there can be no doubt that this incident was a near miss – and that it gives much for the recipients of Staffordshire arborist training to learn from.

A one-way loop system was being used to extract the timber that was involved in the incident, having been successfully used on other parts of the same and similar sites by the same harvesting team. The agreed working method entailed the part-loading of the forwarder on the 30 degree slope of the steeper upper sections, prior to topping up to the full load on the lower sections. Unloading then took place at the loading bay, followed by the forwarder’s move back to the top of the loop.

On this occasion, however, a full timber load had been taken on by the operator at the site’s top steepest section. The machine was rendered unstable by the stacking of the load up tight against the bunk head, which was set in the forward position. Greater stability would have been ensured if the bunk head had been set further back, given how much more evenly the load’s weight would have sat over the back wheels.

The operator’s failure to watch/monitor the bunk section while driving forward down the hill meant that the rear section was allowed to snag and drag on a pile of brash, resulting in the tipping of the bunk, which took the cab over with it.

Not only is the Valmet 865 fitted with glass front windscreens, side and door windows that can be broken to allow their use as emergency exits, but the rear windows are also Margard/Safety glass, giving the operator protection during the loading/unloading process.

At the very least, there is a lesson to be learned of the importance of operators always wearing a seat restraint to hold them in the centre of their cab in the event of their machine overturning.
