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

Less Carbon Dioxide Absorbed by Amazon as Trees Die Off
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.

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.

England and Wales revealed to have 280 million trees

England and Wales' trees have been officially countedFor the first time ever, in news that will be of interest to many considering arboricultural training, all of England and Wales’ trees have been officially counted. The wonders of aerial mapping technology have enabled an exhaustive tree survey to be carried out, revealing there to be some 280 million trees in Britain.

Some of the findings of the resultant National Tree Map by Bluesky are surprising, such as the news that Greater London and Surrey boast the highest concentration of trees, more than many of the country’s most rural areas. Greater London’s average tree coverage was 21.5 per cent, with other areas of the capital to rank prominently in the list of 347 districts and boroughs including Camden (16th, with 30.27 per cent), Croydon (18th, with 30.17 per cent) and Harrow (22nd, with 28.1 per cent).

The City of London, however, languished down in 342nd place, due to its meagre 4.38 per cent tree coverage. Every tree measuring three metres or above in height was included in the survey, in which the highest-performing area for coverage was Surrey Heath, with 40.6 per cent, followed by another part of Surrey – Waverley – with 40.2 per cent, and Bracknell Forest in Berkshire, where coverage was 39.8 per cent.

Indeed, of the top 10 ranking areas, seven – also including Runnymede (37.8 per cent), Woking (36.9 per cent), Mole Valley (36.8 per cent), Elmbridge (36.2 per cent) and Guildford (35.8 per cent) – were in Surrey, with Neath Port Talbot in Wales figuring in ninth with 32 per cent, while New Forest, Hampshire’s 31.4 per cent figure was enough for it to round out the top 10.

James Eddy, Bluesky’s technical director, attributed Surrey’s dominance in the rankings to “the big gardens and big houses with all the trees. [In more rural areas] they have taken out huge rows of trees and grown crops — that doesn’t go on in Surrey. We were also quite surprised at London and how green it is.”

Officially the least green parts of England and Wales, meanwhile, are South Holland and Boston in Lincolnshire, where a mere 2.1 per cent tree coverage was recorded. They were closely followed in this ranking by the 2.3 per cent of Fenland in Cambridgeshire and the 2.5 per cent observed for Barrow-in-Furness, Cumbria.

Rachel Tidmarsh, Bluesky’s managing director added: “It’s really interesting to be able to blow some preconceived ideas out of the window and dispel many popular misconceptions that surround the way we view the places where we work, live and play.”

Ian Morgan Arb Training gets behind DART

DART (Disaster Arborist Response Team)Ian Morgan Arb has supported many local companies and Arb events in the past . This year’s APF stand organisers coincidently placed the Ian Morgan Arb Marquee next to a stand run by the DART Charity.

DART stands for Disaster Arborist Response Team
“These guys deserve our support. They are all volunteers and travel all over the world” said Ian Morgan.

Working on a totally voluntary basis this charity sends Professional Arborists to some of the most hard hit natural disaster zones in the world.
In the aftermath of a natural disaster, fallen trees in the roads are often obstructing other lifesaving humanitarian resources getting through to the effected people. In some cases the uprooted trees present additional concern and can cause injury and even death months after the initial disaster. DART understand and appreciate the dangers and also the environmental effects of a disaster.

Ian Morgan said “Using their skill and time to support local people as they try to re-build lives, homes and entire villages in my mind is simply … well a most worthy cause for my Support”.

Ian goes onto to say “They’re not asking us to put our lives in danger, they are asking for financial support so that they can“.
Ian Morgan Arb Announces that DART is their chosen Charity to Support throughout 2015.
