The Autumn/Winter edition of The Tree Council newsletter Tree Talk is available here
The recent South Norfolk Tree Warden Forum was a great success. Many many thanks to Jamie Foster who gave an enlightening presentation followed by an informative walk through the Poringland Community Woodland.
Tree Wardens feedback on the forum.
Many thanks to you for organising yesterday’s event. I found it fascinating
and informative but, at the same time, quite depressing regarding the
uncertain future facing much of our woodland. Jamie’s views on how best to
manage our trees provide much food for thought and obviously calls into
question much perceived wisdom. It would be interesting to follow his
thinking as this whole issue evolves and his ideas bear fruit, or not, as
the case may be. Looking forward to more such in future.
I found the talk very interesting and confirmed many of the things I had observed over the past few years. I think it would be good if other professionals attended this talk, such as Landscape designers, house builders so they can see the importance of planting areas in a sustainable manner.
It also made me realise the enormity of the problem and how trees in the future are going to become even more unpredictable.
Despite the appalling weather is was time well spent
Another enjoyable, excellent and informative morning – despite the rain, learned a lot; Please keep them coming, we have the enthusiasm, but we can never have enough tree knowledge

Several of our Tree Wardens attended this event to promote the South Norfolk Tree Warden Network. Over 100 people participated in a Tree ID Challenge. We also gave away a number of tree saplings donated by wardens. Thanks to everyone who helped make the day such a great success. Go to the gallery to see some photos.

Report from Jamie Foster
Subject: Structural Failure caused by SOD/die back
To view Jamie’s Pictures click on the Link below:
The pictures attached are taken from the area shown on the map below. The shearing of the Oak occurred at approx 11:30am 07/06/2017, in moderate winds of 20mph (gusting up to 30mph) and 90% + humidity. The Oak has a few tell tale signs of SOD/die back but only when very closely looked at (leaf, twigs and bleeds). The signs are very obvious when dissecting it (we have kept the whole tree). The tree looked healthy to the untrained eye with only a canopy of small deformed leaves dripping from the end of the branches and a small amount of staining on the trunk. The bleeds were more obvious in the top canopy.
The trunk is solid with no classic signs of specific or non specific rot. The hart wood was saturated with water/sap as if it had been pressurised. The sap wood was dry.
The tree appears to have blown itself apart – humid moderate wind, causing maximum water draw, the sap wood being broken down by SOD/dieback and not functioning correctly meant the water is being forced into hart wood and causing the structural failure at the weakest point (just below the bowl of the crown or 10-15ft from ground), the moderate wind was all that was needed to shear 3ft of what appears to be solid Oak. I have never witnessed anything quite like this.
The sap wood on the structural branches has also started to separate from the hart wood, where the canopy hit the ground (in the same way as peeling the twigs). Without question the biochemistry of the internal structure of the tree (lignin and cellulose that make up the main building blokes) is being broken down by a fungus.
The other pictures of the Scots Pine and Oak are from the next garden, all have occurred in the last 5 months. They are all mature/veteran Scots Pine all with specific rot in the centre and 3-4 inches of solid sap wood that has just collapsed. You can see all the fungal spores on the crumpled sap wood. You can see tiny bleeds on the trunks and twigs they have all the normal SOD/die back signs. Again the trees that have sheared appear to be the healthier ones with an average canopy. All the trees are in a very sheltered area that hasn’t changed for many decades.
It appears trees in a stressed situation (Poor ground conditions, other trees/shrubs with more vigour competing for resources etc) are dying from the top down as they can’t get water up to the canopy and sugar down to the roots, so they are steadily dying (later in leaf each year, less leaf each year and then August time become a dead tree).
It should be noted that each species of tree and at different ages will deal with the same stress differently e.g a mature Oak will cope with ground compaction better than a Veteran Beech (Oak has a hart root – sophisticated, Beech a hat sand Root system which only goes 18 inches deep no matter how big the tree is).
If a tree is less stressed it appears to be trying to deal with the fungal attack by trying to produce lots of smaller than average leaves/needles and only at the tips of the branches e.g. the last 2 ft of a mature Oak. This is exaggerating the wind leverage and collapse/summer branch drop potential caused by humidity. Humidity often peaks at 4.00 – 6.00pm Which is when people are often under trees especially big beautiful Beech, Oak and Pines!!!

The South Norfolk Tree Warden Network had two candidates shortlisted for an award at this year’s event. Henry Gowman and Chris Brooks were ‘head to head’ for the Environmental Champion of the Year award. In the end Chris (Tree Warden Scole) got the nod. Great to see the work carried out by our wardens throughout South Norfolk is getting the recognition it deserves.
Sunday 26th February East Hills Wood Project
Work on this project continues and Pauline Williamson (Costessey TW) would welcome help from fellow Tree Wardens. See her note below for details. Pauline can be contacted directly…📞01603 742491 or 📧 email@example.com
Hi Henry. Just a short one to let you know we are now definitely planning another session for the community to assist with bramble clearance in East Hills Wood on Sunday 26th Feb from 11 – 3, and would appreciate it if you could circulate this to the Tree Wardens. We shall meet in the Car Park to the woods on Longwater Lane Costessey, just opposite Pyms Estate Agents. Stout shoes, warm clothes and if possible tough thornproof garden gloves are recommended, but we shall provide the necessary tools for the work. It would be great to have the support from some of the Tree Wardens.
Tree Warden vacancies
We have a number of Parishes that have no active Warden. We have contacted each of the Parishes to encourage them to fill the position. However if any body knows someone who would make a good Tree Warden please ask them to put themselves forward to the relevant Parish Council. For details of the vacant posts follow the link.

Planting Project at Norwich Research Park
ADVANCE NOTICE: Following on from discussions between SNTWN and Norwich Research Park there is to be a mass tree planting exercise in their grounds, on Tuesday 7th February. SNTWN have helped in designing the planting scheme and choosing the varieties, and we will also be overseeing the ordering process. The project will be paid for by NRP.
There will be several hundred trees to plant and NRP are asking the people who are employed in the various companies on the site to take part. Many of these people will be willing volunteers but inexperienced tree planters and so I would very much appreciate as many of you as possible coming along and taking part, both to plant trees and make sure your fellow planters are going about it correctly. If you would like tuition and practice in tree planting, then this event is ideal for you. A light lunch and beverages will be provided.
This promises to be a enjoyable, practical and fun day – I will have a bit more detail to give out at our meeting but please put the date in your diary.
With best wishes,
Our next meeting of the network will be at 7:00pm on Wednesday 18th January. As usual we shall be using the meeting room at SNC offices at Long Stratton.
