Trees are central to natural life in the UK, and an important consideration on development projects. Coombes provides a range of essential tree services to ensure you can plan and build safely, efficiently and in compliance with all relevant legislation.
Tree surveys (BS5837 standard) are required for most planning applications where trees are on or adjacent to a development site – they’re applicable to small works like home extensions as well as more substantial projects, such as large housing developments.
When we carry out a tree survey, we’ll identify and map all trees on your site - with their dimensions - and then categorise them by importance based on species and positioning. Planning authorities can then use this information to determine how your development will impact the natural landscape.
If a Tree Survey shows that your development site contains any trees that are protected by planning authorities – under what’s called a Tree Preservation Order (TPO) – you’ll need formal approval from your local authority before going ahead.
With Tree Survey data to hand, Coombes’ environmental and ecological experts can guide you through the application process to ensure your project keeps moving forward.
An Arboricultural Impact Assessment (AIA) is a specific type of tree survey that determines how your proposed development works will impact any trees on site. It also considers the impact that trees could have on your development in the long term, so it might influence your plans.
Although tree removal is the most familiar impact of development, it’s only one part of the AIA. The assessment also looks at how construction methods could affect root areas, for example, and predict whether future tree growth could cause pressure or obstruction issues for buildings.
In instances where you’re required to plant new trees, either to offset removals and meet planning criteria or to benefit the long-term biodiversity of your development, Coombes’ environmental experts can help you put an effective and compliant planting scheme together.
Based on the soil types and topography of your site, we can advise on what species of tree will be most suitable, all in line with the British Standards Institution’s recommendations (BS 8545:2014). Our easy-to-read plan will then tell you where to plant each tree, and the reasons behind our recommendations.
Oak processionary moths (OPM) – and more specifically their caterpillar, or larvae – are health hazards not only for humans and animals, but also trees. It’s important, therefore, that landowners and developers who have oak trees on their sites can control OPM populations effectively.
In line with guidance from UK forestry authorities, Coombes uses various techniques to help oak tree owners remove OPM populations or prevent their growth, depending on the time of year. During spring months the focus is on chemical control of larvae, and then we switch to removal using industrial vacuums outside of breeding periods.
