This feature is planned, designed and managed to:
Biodiversity is an indicator of a healthy environment. With many plant and animal species under threat of extinction, biodiversity decreasing in the UK and globally.
TfL's green infrastructure forms corridors of woodland, street trees, scrub and grassland which are part of London's cultural heritage and act as a safe haven and dispersal route for plants and wildlife, including bats, badgers, reptiles and water voles. Our green infrastructure also helps to:
Our main focus when managing our green infrastructure is on safety - for our passengers, and for our staff and contractors. We do this by:
We also explore opportunities to introduce green infrastructure as part of all projects. This helps us deliver on commitments in the Mayor's Transport Strategy, and contributes towards the aims of the London Environment Strategy.
We are committed to increasing the number of our street trees by 1% each year, and building a resilient tree population to benefit future generations.
Grass cutting or mowing regimes will vary depending on where you are on the network. We are also trying to reduce the number of times grass is cut in some areas to encourage wildflowers and pollinators.
Non-native invasive species and pests can cause a lot of damage to both our green infrastructure and transport infrastructure. For example, oak processionary moth caterpillars not only cause a risk to human and animal health, but can strip whole oak trees bare of leaves, while Japanese knotweed can damage structures like walls and roads.
We use several different methods (chemical and mechanical) to deal with weeds and non-native invasive species. We make sure that we follow the legal and Government guidelines that apply to any method we use.
We are looking for ways to reduce our use of herbicides. For example, we are trialling alternative/complementary methods across our operational networks to identify the method that represents best value for money with least environmental impact. We are also exploring how we can use integrated weed management techniques to improve performance
