20080722 Cutting

This page illustrate an example of problems inherent in Park management and especially in public relations with the park end users.

It is often forgotten that parks are created to ameliorate the lives of residents and their feedbacks and care for the green spaces should be an essential part in considering strategies for the area management and its overall purpose.

The East side of the Surrey Square Park had only one tree.

Here it is providing shadow in the hot summer a couple of years back

It was planted when over 25 years ago the parkland was created. It had sustained some damage when the great wind storm of 1989 broke one of the two main branches. Many people at the time thought that it would die but like many other lime trees it showed an extraordinary resilience.

Here it is the last winter amongst the frozen blade of grass. Note how well proportioned and healthy the branches are. This was not a sick tree at all.

Here it is healthy an leafy last autumn.

Not only it did not die but it thrived.

It was amongst the very few trees planted on the park inception some 25 years ago and had become mature and healthy, albeit with the scars left from the big wind storm.

Many birds used it for nesting and gave the park a little more character.

All gone.

The miscreants cutting it down.

The contractors without warning came along and felled it.

Now as anyone can see the Park, small as it is and in need of more trees and vegetation, has become significantly poorer.

It feels like a slap in the face of the so many residents that have recently fought to save the little green park from the proposal to built it over and that were promised that not only the project had been scrapped but that the park would have been improved.

Many felt that the promises to involved more the residents has been already been broken.

Here is the park now. Poorer and emptier.
But the residents can only remember it !!


Allison, another long standing resident that has been involved in the care of our little park has also contributed the following images and you can find her Flickr links here and here

On the reason why the tree have been cut there have been some developments.

Letters of enquiry from Julian, the secretary of the Kinglake T&RA have been replied.

He addressed the original letter to Jon Best, the Southwark Ecological Officer, that although is probably not involved with the Park maintenance, could readdress the letter to someone responsible for the deed. Because Jon was absent Julian resent the email to Mr Stavros Valiris the supervisor in charge for the contractors works in Surrey Square Park.

Here his letter:

Dear Jon,

As part of some tree works taking place in and around the Kinglake Estate

yesterday, a large mature lime tree on the perimeter of the park, adjacent

to Southborough House, was cut down. Only a 1.3m section of the trunk

remains. I would like to know why it was cut down. Apart from some yellow

parking restriction signs put up a few days beforehand, we received no

notification of the works.

Please, could you forward me the name and contact details of the manager

responsible for tree maintenance on Surrey Square Park? I realise that

Surrey Square Park and Kinglake Estate are probably on different maintenance schedules. If you could send me any contact details of relevant maintenance personnel I would be very grateful.

I have spoken to Stavros Valiris on a number of occasions, about park

matters, and have found him helpful and supportive in our endeavours to enhance the park. He was instrumental in creating some uncut areas of grass around the perimeter of the crater playground on the park, to enable wild flowers to flourish. However, trees don't seem to be within his remit.

All too often, sensitivity to wildlife seems to be lost, somewhere along the line, in handing out maintenance schedules to sub-contractors. Another example of this that happened on Kinglake Estate about a week ago behind Amery House - a small grass area had become overgrown, and was due for cutting. However many wild flowers had sprung up, creating a mini wild meadow, which added colour as well as biodiversity to the place.

The contract was presumably to cut the grass, so everything was cut down. With better communication, surely it would be possible to retain some uncut areas around the verges or at least on the perimeter?

Myself and a small group of local residents are currently in the process of setting up a Friends of Surrey Square Park group, and would like to establish better contact with Council officers responsible for maintenance of the park, so that we can work together, and hopefully establish maintenance programmes which are more sensitive to the needs of wildlife and biodiversity.

Unless we introduce more flexibility and sensitivity into our Park and the Estate maintenance, and engage support of local residents, wildlife is never going to flourish here.

I would welcome your comments.

Regards,

Julian

Mr Valiris very kindly then sent it to the Arboricultural Officer, Rosalie Dobson , that at last replied with the reason why the tree was felled.

Here what she says:

Dear Julian

The tree opposite Southborough House was cut down on a job that I issued, as a result of a health and safety survey carried out in 2005. The surveyor identified basal decay and trunk rot, and recommended tree removal. I do appreciate that it is possible to maintain trees with dead or decaying wood in certain areas and aim to do so wherever possible. However, the tree surveyor would have taken these factors into account when making recommendations.

We do not normally carry out formal notification when removing trees, but aim to attach a felling notice to any significant tree which is being removed at least five days in advance. I apologise if this was not carried out in this instance.

Please let me know if you would like to arrange a walkabout in order to establish contact and discuss any future tree work requirements. You can contact me by e-mail or on my direct line: 020 7525 2089.

Kind regards

Rosie Dobson

So I have done some investigation for myself.


Here the trunk from the side and the front. Note the big scar left by the wind damage in 89 when the tree was basically cleaved in two. The count of the growth rings gives an age of 27-28 years.

The trunk viewed from above show how deep the scar run along it. The part of interest is at the bottom. I removed some detritus (some is still there) that made it appear that the cavity was sealed.

Some close-ups and some comparative measurements.

Note some that has been detritus removed next to the end of measuring tape.


Under the plug a cavity with water can be seen. The cavity expand at the base of the stump and enlarge laterally. A micro fauna was also present.

It is not a huge cavity but it certainly exist.

None the less the tree survived some windy days prior to be felled and generally basal rot is associated with fungal decay (see for for example Decay_Fungi_1.doc) that usually produces fruiting bodies like Ganoderma adspersum (a typical fungus responsible for "tree or basal rot").

I personally never observed any of that on the tree so maybe the infection was not so pervasive yet and certainly the quality of the wood seemed healthy enough.

I think, it is a moot question if the tree could have been treated even at this late stage ma above all why it has not been treated in the twenty or so years that the cavity has taken to form?

On these very topics I receive a comment from Rosie Dobson

Thank you for your e-mail, which Jon Best forwarded to me. I read your webpages with great interest, and apologise sincerely for the distress which this tree removal has caused.

Firstly I would like to invite you to join me in a site meeting with Julian Weston and other members of the TRA which we have provisionally booked in for 9am on Thursday 7th August. if you are unable to make this time, perhaps we could meet on another occasion.

In answer to the questions you ask in your webpage:

Trees can fail unexpectedly and it is difficult to assess the risk that they pose. Just because a tree has withstood heavy winds in the past, does not mean that it can continuously be considered 'safe'. It is the job of the tree surveyor to assess each tree individually and determine whether or not it poses a significant risk. The tree inspection will include an assessment of the overall tree vitality, and an assessment of any significant defects. Large trees with significant defects will be considered a potential risk and are heavily pruned or removed.

You are correct in stating that basal decay is often caused by decay fungi such as Ganoderma. However, there are decay fungi species which have much smaller and ephemeral fruiting bodies, and it is possible that one or more species is also present, as once the wood is exposed, it is more likely to be attacked by decay fungi.

Research into the stability of hollow trees, shows that trees with an open cavity have a greater likelihood of breaking than trees with no cavity or trees with a closed cavity. (For further details see Mattheck and Breloer, 1994, The Body language of Trees) [1].

Unfortunately I did not inspect the tree myself, but am the officer coordinating the works. However, I would hope to be able to trust the judgement of my surveyor in this instance.

You ask why the tree was left for 20 years before anything was done. There are several reasons for this. Firstly the larger a tree is, the more potential it has to cause harm, so a small tree with a basal cavity could be assessed as not being a risk, but as it increases in size, the potential to cause harm increases and the tree is more of a risk. Secondly, it is only in recent years that the council has been able to undertake a comprehensive survey of parks trees. Unfortunately this can result in a seemingly large number of trees being removed, because the problems have not been identified previously. In addition, there is a limited budget for carrying out tree works, so each year I am able to assess and work on only a certain number of trees.

Finally with regard to tree planting, we endeavour to increase the tree population in the Borough every year, by planting more trees than we remove. I appreciate that new trees do not have the same wildlife and amenity values as mature trees, but at least by removing trees when necessary and planting new specimens we are aiming for a tree population which is healthy, contains a range of age groups, and will be sustainable in the future. I would be happy to discuss replacement planting with you, and the other TRA members.

Please contact me with any further questions.

Kind regards

Rosalie
