Beech infected with Meripilus Giganteus

Giant Polypore, Meripilus giganteus

Aswell as structural damage (loss of co-leader) some years ago this Beech tree had been infected by Giant Polypore, Meripilus giganteus.

This parasitic fungi can cause extensive internal damage before any external evidence of presence can be seen. It infects and grows on the roots and the trunk base of the host broadleaf, particularly Beech. Infection occurs via wounded or damaged tissue, the fungi establishes on deadwood before attacking the tree's living tissue. The first evidence of infection can be crown dieback or defoliation (as in this case). Bracket like fruiting bodies are produced in late summer or autumn at the base of the stem or from the ground immediately above any infected roots. 

With this tree an infection had been confirmed by the presence of fruiting bodies late last summer and felling was considered a requirement as the tree is located in a public access area and as decay progresses the tree weakens and the root anchorage fails. 

Stem girth at 1.5m was 4.52m

Felling from a different level

Felling of a Co-Leader at 50 feet

Trees that have suffered structural damage are sometimes to dangerous to section down using climbing techniques. This mature tree had suffered a sever lateral fracture through the main bifurcation in the stem. To deal with this tree safely we had to use an Acces Platform (Cherry Picker) to remove all of the crown from above the fracture point. 

This film shows us felling one of the co-leaders out of tree. From a safety point of view; We were absolutley certian that the weighting of this leader would mean that it would fall away from us. We had identified a possible internal fracture at the point where we were making the felling cut and we were able to get an apporpriate angle on the hinge to deal with this.  On the ground we had cleared all obstacles and had ground staff to stop any movement of people or vehicles during the operation.

Felling with the Tifor winches

Felling a Leaning Spruce.

Spruce can be notorious for suffing from root plate lift in strong winds, this one was no exception. This Spruce was located in a small stand of trees, on a slope near the gable end of a house. There are power lines running between the house and the trees. The tree was leaning in the direction of the house and lines. As it happens this tree is being supported by the surrounding trees and they are stopping it from going over. How do you tackle something like this? This is the approach we chose to take!

Firstly closely inspect the tree to make sure that it can be dealt with safely in the way that we want to deal with it. 

Climb the tree removing the limbs from the direction it is going to be felled; remove the limbs from the ground up to a point where they are in contact with the surrounding trees, these will be under tension! Having these limbs removed allowed us a space to attach winch wires to the stem so that they have a clear line towards our anchored winches. Two winch wires are attached to the stem, one about two thirds the way up this 60-70ft tree, the second about 6ft below the first. Why two winch wires? The first and highest is the one that will be used to pull the tree over it being high up the stem gives maximum leverage. The direction of fell is across the slope. The problem is trying to control a tree like this with a compromised root plate. There is a chance that as the tree is being pulled to the vertical that it might start to veer downslope; fall along the fence line damaging the fence landing in a position that would be difficult to deal with. A second winch was therefore to be used, it being placed up-slope 45 degrees from the line of fell. The theory being as the tree is pulled to the vertical on the first winch the second winch is kept tensioned so the tree can not head downslope. Once the tree is beyond vertical and heading in the line of pull towards the first winch, also guided by the direction of the felling cut, the second winch wire looses tension but would still restrict the tree falling downslope.  The result was a tree safely on the ground. All that remains would be to tidy up.

Climbing kit needed for hedge cutting

20ft Cypress Hedge

Now that the planting season has come to a successful conclusion we are back into the routine of grounds management, tree work and fencing.

News for the New Year

All the best for 2013

Best wishes to everyone for the New Year from all at Treesurv.

It looks set to be a busy year with the planting work now well under way at the Corehead project and plenty of tree management work to fit in a long the way.
We had a busy time over the Christmas period with a native planting project at Fruid Farm, Tweedsmuir. This work involved Cleuch planting to re-establish habitat for Black Grouse, The interesting thing in doing this is that it is in a valley that connects up to the native planting we are undertaking at Lochan Burn, this also having the objective of providing habitat for Black Grouse. Further to this both sites are not too far away from the already established Carrifran Wildwood Project making the wider area in general something special.

Sunday the 6th Jan we are going to be having a get together at the Bothy in Lochan Burn for a drink and nibbles to welcome the New Year and toast the final phase of the planting work at Corehead. All are welcome and the plan is to meet at the Bothy for between 12 and 1pm. 

Over the next week we are going to be sending all of our clients a 2013 calendar but if you don’t receive one please don’t hesitate to contact us and we would be more than happy to send one to you.

Underplanting with Evergreen Oak, Quercus Ilex

Not all of our planting work means being on a remote hillside. Sometimes we are involved with planting in formal city gardens.

Ash Dieback Disease

Help identify the spread of the disease.

Too little too late? That is the question. Have the Powers That Be been a bit slow off the mark to do something about the spread of this disease? The Chalara Fraxinea Fungus appears to be spreading throughout the South of England. The BBC reports that 100,000 trees have now been destroyed to try and prevent the spread of the disease; they also report that 90% of the Ash population of Denmark has been killed by this disease! As clearly this would not have just happened over night, why were measures not put in place long before now to prevent the spread of the disease to the UK?.

We all need to help monitor the local Ash population for signs of this disease. A mobile App has been launched to try and map the spread of the disease. The Ashtag App allows the user to upload pictures and report possible sightings. This information is then passed onto the Forestry Commission. 

For more info on what to look for, check out

Let's all keep our eyes open for this one!
