Trees in parks and open spaces

Arbor team at the top of a tall oneTrees are a very significant feature in the boroughs parks and open spaces. They provide a variety of benefits not only to visitors but to the overall environment of an area.

To ensure that trees continue to contribute to the landscape it is essential that we think about their health and safety.

The inspection and maintenance of trees within parks is the responsibility of Carillion Integrated Services.  Carillion Integrated Services is responsible for the overall maintenance of the all parks and open spaces. The council will ensure that the management of the trees is undertaken in accordance with Arboricultural best practices and legislation.

"When I went to my allotment last week it was a wonderful.... surprise to find the tree actually gone... Thank you as well for doing a good job of clearing up the job well.." Hounslow resident.

Annual Tree Inspections

As part of our commitment to improving parks and open spaces we annually undertake a comprehensive visual inspection of all the trees within the Parks and Open Spaces, on behalf of the London Borough of Hounslow, in order to collect information about the borough's tree stock such as:

  • Tree condition
  • Tree dimensions, height, diameter, crown spread etc
  • Age
  • Classification – species etc
  • Location

This information will then be used to inform subsequent management and maintenance programmes. These programmes will be delivered on a site by site basis and works will be undertaken to remedy any identified problems.  Click here to see the Annual Maintenance Inspection Program

What type of maintenance is carried out on trees?

            • Lifting low branches over footpaths.
            • Cutting back branches from lamp posts.
            • Removal of deadwood.
            • Removing weak or damaged branches

These works will also be available for public viewing via this web-site in the near future.  Click here to see the Annual Maintenance Program

Will any trees be removed following the survey?


It is sometimes necessary to remove trees when they are dead, dying, and diseased or when there is structural damage.  Click here to see the Annual Maintenance Program

How do you know when a tree is diseased or dying?

Diseased trees can often appear to be perfectly healthy, but a detailed inspection by a qualified tree officer can reveal problems that are not obvious to the untrained eye. All our surveys are conduction by trained arboricultralist.

Specialist equipment such as PICUS® Tomograph may be used to provide extra decay detection and analysis of the inside of the tree once a visual inspection is completed. The PICUS® Tomograph consists of a set of sensors which are placed around the part of the tree identified as potentially suffering from decay or having a structural fault. Each sensor is connected to a nail which is tapped through the bark into contact with the wood beneath. This process is virtually non-invasive to the tree’s living system.

How will I know if you are planning to remove trees from my local park?

If we identify any trees that need to be removed we will:

  • Post notices on the tree identify that the tree is earmarked for felling
  • Update our website
  • In cases where there are major works that need to be undertaken that may affect access to the park we will notify residents nearby by letter
  • Trees that are deemed to be of a high hazard risk to public safety may be removed without notice to the public.

What about bats?

It is sometimes the case that trees with cavities may provide a roost for bats. All bats are protected under Schedule 5 of the Wildlife and Countryside Act 1981 and are also included in Schedule 2 of the Conservation (Natural Habitats &c.) Regulations 1994. These include provisions making it an offence to:

  • Intentionally kill, injure or take (capture) bats
  • Intentionally or recklessly disturb bats in a roost or any other structure or place it uses for shelter or protection
  • Intentionally or recklessly damage, destroy or obstruct access to bat roosts even if bats are not in residence

A bat survey will be undertaken prior to any works being undertaken to determine and mitigation works incorporated into the schedule if required.

Can you cut down a tree if it has a tree preservation order (TPO)?

Consent is required before any works can be carried out on a tree TPO. This includes pruning, lopping, felling, crown raising etc. We will not undertake any work on a tree that has a TPO ( unless it has been deemed to be of a high risk hazard to public safety ) with gaining prior consent from the councils planning department.
