We plant and maintain street trees because they deliver environmental, economic and social benefits.

Proximity to green space is linked to increased birth weight in babies as well as increased life expectancy in the elderly. London boroughs with a lot of trees tend to have lower prescription rates for antidepressants.

London's urban forest helps to remove airborne PM10 particulate matter. Trees also contribute to water management by intercepting and holding rainfall, reducing surface water runoff from asphalt by as much as 62% and lowering the costs associated with storm water management.

Woodlands, shrubs, wildflowers and green walls are also part of our green infrastructure. Well-maintained green infrastructure has been shown to reduce crime and even improve driver behaviour.

Wildlife variety

The land surrounding our rail tracks acts as a safe haven for wildlife that includes bats, badgers, reptiles and water voles.

Altogether around 550 plant species, 42 bird species, 14 mammals, 538 invertebrate species, three reptile species and three amphibian species have been recorded on our land.
