Tree Protection Fencing is a term that includes a variety of techniques, and that has different requirements for different client bases.
Because of Knighton Countryside’s unique position in land based industry, we are able to offer any and all types of tree protection.
BS 5837:2012: Trees in Relation to Design, Demolition and Construction.
BS5837 provides a statutory duty on local authorities to consider the protection of trees that are potentially affected by developments. All trees that are to be retained need to be protected by barriers and or ground protection which will be detailed in the tree protection plan. This has to be in place prior to any machinery or materials being brought on to site to commence construction.
As part of preparation work on a construction site, Knighton are able to install BS compliant tree protection fencing quickly and efficiently. This is particularly advantageous if Knighton are also carrying out wildlife mitigation at the pre-construction phase, as the same team can carry out all the work: a more efficient process than using several subcontractors. We can install site hoarding as required.
Knighton are also experienced in using products such as Cellweb® for ground protection to provide no dig solutions if required. Ground protection for high traffic areas can protect vulnerable areas from soil compaction, which may lead to damage to the root systems of retained trees.
As Arboricultural Association Approved Contractors we can fell any trees approved for removal, and we have the capability to transplant trees using a tree spade. We are also able to carry out any new planting, and any remedial work that might be required, both at the preparation stage and at the end of a project. Using both above and underground fixing systems we can plant mature trees if required.
Tree protection fencing can be used to create a physical barrier around invasive species such as Japanese knotweed where contact site traffic could risk spreading the plant. Knighton are also able to offer an invasive species eradication service.
A different aspect of tree protection is the use of tree guarding products when planting. Whether you are planting whips as part of a large project, or larger specimen trees, they will very often need protecting. The type of product used varies greatly depending on its intending purpose.
Solid tubes, such as Tubex, protect against drought by retaining moisture within the tube. They offer some protection against frost damage and wildlife damage. The solid tube protects against sprayed herbicide damage, and also against damage from brushcutting or mowing around new planting.
Mesh guards are more suitable for some planting as they all air to circulate more freely around the the saplings. This is appropriate for some species, such as conifers or beech, and we are happy to use this rather than solid tubes if preferred. Like their solid counterparts, these guards offer protection from wildlife and accidental damage, though less protection against accidental herbicide contamination.
Spiral Guards are great for sheltered sites and provide excellent protection against rabbit damage. As they tend to be secured with a cane rather than a stake they are not quite so suitable for very windy spots.
The different types of guard are available in a number of sizes, depending on the size of tree being protected, and what it is being protected from. For example, vole guards need to be considerably smaller than deer guards! All the guards are designed to expand as the tree grows, or to split and fall away when the tree reaches a certain size.
For trees in parkland or larger open spaces a basket guard may be the best solution. These can be constructed from iron railings or wooden post and rail, and excellent for protecting trees in the long term.
