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

Less Carbon Dioxide Absorbed by Amazon as Trees Die Off
Increased mortality rate

It is estimated that in the 1990’s the Amazon absorbed up to two billion tons of CO2 each year but since then, according to the study now absorbs less than half of that.

The study was limited to primary and undisturbed forests, which makes up about 80% of the Amazon. So it doesn’t account for carbon changes, regrowth or deforestation so more research will have to be done in order to provide a more rounded result set but Lars Hedin, a professor of ecology at Princeton University suggests that the research done thus far will form an excellent springboard for a future research and understanding.

He writes: “The CO2 component of climate change may become substantially more difficult to manage and abate in the future if the findings from the Amazon basin apply more generally to the land carbon sink.”

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.

How can arborists limit the spread of Chalara?

CHALARA SPREADSA critical element of arb training for many is knowing the best means of limiting the spread of Chalara, the fungal disease that already besets so many of our ash trees and is tipped to ultimately infect most of the country’s ash tree population, akin to the notorious 1970s Dutch Elm Disease.

The importance of minimising Chalara’s spread cannot be underestimated. The risk of the transmission of spores via infected leaves means that one must always try to guard against new areas becoming infected through the adoption of sensible biosecurity precautions.

The fungus that causes the disease, Chalara fraxinea, is capable of surviving up to a year of frost or leaf degradation, but cannot fruit if buried. Although it can be killed in some cases by the heat that composting generates, this cannot be guaranteed and it is unlikely that sufficient heat to kill the spores is generated by the smaller scale heaps seen in parks and gardens.

Recipients of our Staffordshire arborist training working on any site should always heed any requirements outlined in statutory Plant Health Notices over more general advice. Nonetheless, those intending to fell or prune infected trees are advised to wait – if possible – until leaf fall before doing so.

Infected leaves may not need to be removed at all in some circumstances – it is widely advised to leave infected mature ash trees, for example, in place. The fungus in the ash tree leaves that causes the disease is able to be spread by airborne pathways or by physical movement through human agents. It is the movement of infected material, such as plants and leaves, that generally causes the spread of Chalara into new areas.

As a general rule, the smaller the volumes of leaves being transported and the shorter the distance they are being transported, the lower the probability of the spread of the disease. If leaves that have been affected by the disease do need to be disposed of, the emphasis should be on using on-site disposal options available on or near an infected area, thereby minimising the risk of infection spreading to other areas.

Those benefitting from our arboricultural training in Staffordshire should also be aware of the low risk status of timber/cordwood that means there is no control over its movement at this time. Measures should also be taken by those that have just worked on infected trees and are set to move into other areas with no or minimal signs of infection, to remove leaves and rachis from vehicle tyres, chippers and payload.

The other pests and diseases that can be present nearby only makes the adoption of biosecurity measures all the more sensible for those enrolling in arb training in Staffordshire like that of Ian Morgan Arb.

An introduction to Chalara

Chalara infection Tree DiseaseThere’s no question of the extent to which Chalara dieback of ash – also known as ash dieback or just Chalara – represents a  bane to the lives of many of those receiving arb training in Staffordshire. This fungal disease affects ash trees, causing crown dieback, leaf loss and bark lesions. Even worse is that it is usually either directly or indirectly fatal to trees, due to the weakened tree’s consequent vulnerability to pests or pathogens.

Chalara has been responsible for the infection and death of a significant proportion of Europe’s ash trees, and since its initial discovery in the UK in nursery stock in 2009, it has become prevalent among ash trees in woods, hedges, plantations, parkland and urban areas, particularly in Eastern England. It is thought that infections first began to occur here due to fungus spores being carried on the wind from planted nursery stock on the continent.

With Chalara now well-established in Britain, all chances of the disease being eradicated from here are remote. Ultimately, most of the country’s ash trees will be infected by the disease, in a manner akin to Dutch Elm Disease in the 1970s. Ash trees with the disease can pose a major risk to people and property if they are not suitably managed by landowners.

As a recipient of arb training in Staffordshire, it is important for you to carry out regular surveys of ash trees so that you can take appropriate action. There are certain ways of minimising Chalara’s presence and rate of spread so that you can maximise the amount of genetic diversity in your ash trees and ensure as little compromise as possible to associated species, general biodiversity and timber production. Above all else, the right management will help to preserve ash in the long term.

While ash trees can have certain undesirable effects such as damaging property or risking human safety, they can also be an immensely valuable part of the overall urban, suburban and rural landscape. Where the management of ash trees is advisable, getting this process right will help to enhance the trees’ value, access and other advantages. Deadwood, for example, is not merely a hazard, but also a vital ecological attribute that is depended on by many species.

Ash trees should be retained where possible, in accordance with national guidance. Such trees should not be felled or pruned merely due to the likelihood of Chalara infection, as should be noted by anyone in Staffordshire who takes advantage of arb training.
