Trees and green spaces

Autumnal tree with blue sky

Our highly qualified and experienced team manage over 30,000 individual trees as well as various woodland areas, open spaces, allotment sites, micro-orchards and several sites of special scientific interest (SSSI).

They are passionate about maintaining and improving these different landscapes within the borough as the council recognise the importance of these to residents and the benefits they bring, particularly around health and wellbeing.

More about maintaining trees in the borough.

Become a Tree Warden

Our Tree Wardens Scheme is part of a National Tree Warden scheme by the Tree Council. Our branch has been running since 2006 and we have approximately 60 Wardens who regularly help us monitor street and park trees in their neighbourhood. Becoming a Tree Warden is a good way to take pride in your area and help the Tree Officers manage our tree stock. By becoming a Tree Warden, not only will you get to help protect trees, but you will also be given opportunities to learn, socialise and visit tree-related sites!

What do they do? 

Tree Warden volunteers are the eyes, ears and voice for the trees in their neighboroughood. They're often the first to become aware of local tree issues and bring them to our attention. They provide a vital service by:

  • telling us about a tree they think might have a disease
  • watching for infringements of Tree Preservation Orders
  • informing us when trees start to show signs of ill health or become dangerous through decay
  • helping with planting and maintaining community orchards
  • learn about tree species in their area to support or Tree Officers


No training or experience in tree management is necessary to become a Tree Warden - just a love of trees and a few hours to spare.

It's up to you how much, or how little, you wish to be involved.
