Stoke Lodge Playing Field is a 26-acre site in Stoke Bishop in Bristol. In the north west corner of the field is a gas “kiosk” which houses gas pressure regulation equipment. It was built in 2009, replacing a smaller installation nearby which was not on the same land. It is the responsibility of Wales and West Utilities.
Many locally and nationally notable trees grow on the parkland, a number of them getting quite old now, and in need of some love and our protection.
The access to the compound is over the roots of some of these important trees, most of which are the subject of Tree Preservation Orders. Protected trees surround the compound, and their roots, which are very superficial (as is the way with tree roots) and in places even exposed, are at risk of damage from vehicles driving over them and parking on them.
Tree roots extend radially in every direction to a distance equal to at least the height of the tree (assuming no physical barriers) and grow predominantly near the soil surface.
Typically, 90% of all roots, and virtually all the large structural supporting roots, are in the upper 60cm of the soil.
Soil disturbance within the rooting area should be avoided, whenever and wherever possible as this can significantly adversely affect tree health and tree stability.
Associated with roots are much finer, thread-like, mycorrhizae. Mycorrhizae are symbiotic fungi which grow on or in roots, an association which is mutually beneficial to both the tree and the fungus. They are extremely efficient at nutrient absorption, especially phosphorus, and many trees cannot survive without them.
Diagram of a typical tree root system:
Cars, lorries and vans are heavy. They leak oil and hydraulic fluids from braking systems and power steering pipework and pumps. They also leak windscreen washer fluids. These chemicals are toxic for trees. In the root area of a tree soil compaction caused by vehicles and the deposit of toxic or impermeable materials should be avoided. The nearer to the trunk these things take place the greater is the damage done and the greater the loss of roots.
Local residents are very protective of the trees – this whole Parkland is hugely important for them, and they have taken its care to their hearts.
Vans and lorries from Wales and West attend the site, both for routine maintenance visits and for any “emergencies”.
Recently one of the residents noted a Wales and West van parked on the exposed roots of one of the trees, so they contacted the Company to point out the dangers for the tree’s future that could be caused by this.
The response from a manager at the Company was immediate and most gratifying. Within hours a site meeting had been arranged with the W&W Manager, the Resident and the BTF BS9 Tree Champion in attendance – all suitably socially-distanced!
The Manager listened to everything we said. He told us that Wales and West had not previously been aware of the importance of these trees, nor aware of the peculiarities of the siting of the compound in relation to the trees.
He went on to say that he would do everything he could to inform future Wales and West employees visiting the site of the sensitive nature of the ground they would have to drive over, and that they would keep traffic passing over the root areas to a minimum, allowing only one vehicle to park on site at a time, parking any others required nearby on the highway. The one vehicle needed would not park under the canopies of the trees. It is possible for one vehicle to park clear of tree canopy areas.
He arranged for good quality signs to be affixed to their entrance gate and to the fence enclosing the kiosk, so that Wales and West operatives would be aware of the need to avoid damage to tree roots at this particular site.
The Bristol Tree Forum has been working hard in recent years, with local residents and their representatives, to encourage Bristol City Council, as owners of the land and as Landlord, to ensure that Tree Preservation Order regulations are complied with by their tenant using the Playing Field, and if necessary enforced. We have had some limited success. This made the attitude and actions of Wales and West Utilities all the more overwhelming.
So, we would like to thank W&W’s manager again for his actions on behalf of the trees, and to compliment Wales and West Utilities for supporting an ethos which encourages community engagement and action like this.
The sign (see above) riveted to the main entrance gate onto the site and to the gas kiosk has been removed. It looks like the rivets have been drilled out, rather than the sign being removed by snapping it off, so it must have taken some effort and maybe even some planning to do this. The sign appears to have been taken away.
Who could possible think that doing this ‘vandalism’ could be for anyone’s benefit? It cannot have been Bristol City Council and it is hard to imagine who else would do such a thing. We are investigating.
Wales & West have now told us that they removed the sign, saying “We put them in the wrong place. Now moved to the right place as agreed with the leaseholders of the land.” What leaseholders? As far as we know this bit of land is not leased. It belongs to Bristol City Council.
