What are Arboricultural Services?
Often called a tree survey and which adheres to the BS5837 standard, this service consists of three stages:
- Stage 1 Site Survey and a Tree Constraints Plan (TCP) identifies and evaluates the trees on site
- Stage 2 Arboricultural Impact Assessment (AIA) provides a tree protection plan that summarises the tree work to be undertaken; identifying those trees are to be removed and/or retained, how the tree root zones will be affected. and how trees to be retained will be protected during construction
- Stage 3 Arboricultural Method Statement details how works will be carried while protecting the trees
When Do I Need To Get In Touch?
If your site has trees and you are planning to construct or redevelop the site in some way you will need a Stage One survey (often referred to as a BS5837 survey). By carrying this out early on, delays and extras costs can be avoided.
Trees are a valuable asset that need to be monitored and preserved. When calling on the services of a professional arborist there are several points to remember:
- The owner of trees has a legal duty of care to have their trees regularly checked (more thoroughly if they are located in high risk areas).
- All trees have a monetary value in addition to their amenity and wildlife value. Depending on the method used to calculate the value, it can amount to tens of thousands of pounds for each tree. Most developments increase value and appearance by incorporating good tree specimens.
- Wildlife and planning laws gives protection to trees. It is imperative that the owner is aware of any restrictions to work on trees e.g. Tree Preservation Orders (TPOs), felling licences, or those in a Conservation Area.
How can EcoNorth Help Me?
Our in-house Arborist can advise you on the requirements of your development and trees and deliver all three stages of assessment if required. In order to integrate the BS5837 survey into development process as smoothly as possible and thus avoid delay and extras costs our Arborist suggests the following process:
- Well in advance of submission to the local planning authority, undertake a topographical land survey so that the location of the trees can then be accurately plotted based on this map.
- Ideally prior to any development plans being drawn up our arborist will undertake stage 1 of the survey (a site survey and TCP) so that high-value trees can be incorporated into the design and given enough room to develop. Lower category trees can be removed if needed. Dangerous and unhealthy trees should be removed.
- After the design stage, Stage 2 an AIA summarises the tree work required
- Finally, Stage 3 an arboricultural method statement is done once the survey has identified any possible constraints.
