Three more Ladder tree removals

The following from the Haringey arboricultural dept.:

Following a planned tree inspection in Harringay Ward, this is to inform you that 3 trees have been identified as requiring removal. A removal notice will be placed on the trees advising the public and a resident letter drop (will be undertaken.

1. 7 Effingham Road N8
2. 63/65 Sydney Road N8
3. 69 Seymour Road N8  

The trees have been colonised by decay fungi (Ganoderma) and have other defects which has compromised the structural integrity. These are all serious structural defects. Ganoderma species cause extensive decay of the lower trunk and root plate making the trees structurally unsound with the potential to fail at or near ground level. There is no treatment, or ways to prevent the acceleration of the decay. Most ornamental trees do not respond well to decay and once colonised, their stability can weaken rapidly and this often leads to them failing in high winds. Colonisation by Ganoderma fungi is the most common cause of street trees failing in the borough.

The ornamental street trees are scheduled to be inspected every four years, so on occasions a number of trees may have to be removed at the same time.

The fungal fruiting bodies usually only appear after the trunk or branch are substantially decayed. Ornamental trees do not respond well to decay and once colonised, their stability can weaken rapidly.. Examples of these are illustrated below. All three trees had the same decay fungi. We can upon request supply the images of the fungus on each of the three trees listed above these are already detailed in the resident letter drop.

The tree failed and damaged a vehicle. The tree was colonised by decay fungi Ganoderma and Phellinus

Tree failed and Ganoderma fungal brackets are visible on the lower trunk (seen in image 3)

Clearly shows fungal brackets.

Trees identified with decay fungi or other major defects cannot be safely retained on the public highway where the risk of damage or injury is high.  Unfortunately, in situations like this, removal is the only option. It is regrettable when mature trees have to be removed, however, the Council has a duty of care with regards to trees and must take action where hazards are evident to minimise the risk to people and property.

A new Urban Forest Plan is currently being developed and this will outline where and when new trees will be planted going forward.

The council has launched a new tree sponsorship scheme, which has been set up with an external partner; Trees for Streets. If you wish to sponsor trees in your road please register the interest in sponsoring a tree at the link below.
