Of these, about 135,000 (70%) are privately owned trees mainly growing in our resident’s gardens. The London Borough of Sutton owns the rest, approximately 21,500 street trees and 33,000 trees in parks and other open spaces (not including the trees in woodland areas and the 2,400 trees situated in school grounds).Sutton is very fortunate to have one of the highest densities of trees per hectare compared to other London Boroughs; in total there are more than 190,000.

Trees and woodlands are an extremely important part of the Sutton’s landscape and the well being of residents and visitors; the benefits of which are various (covering many different areas of Sutton’s environment and society).

Environmental benefits:

  • absorbing airborne pollutants like ozone, carbon, sulphur and nitrogen dioxides and acting as carbon sinks (converting carbon dioxide into plant tissue)
  • filtering the air of dust, other particulates and noise
  • producing oxygen
  • reducing localized extremes in temperature (helping to cool the air in summer and warm the air in winter)
  • reducing the effects of flash floods
  • providing habitats for a variety of wildlife

Economic benefits:

  • increasing property and land values (by 5-10% for residential or commercial properties and 27% for undeveloped land (with mature trees present))
  • providing a sustainable source of woodchip bio-fuel (as a by-product of tree works) and a source of compost (leaf matter) for use in parks
  • can provide employment through all aspects of the industry

Social and health benefits:

  • providing a more beautiful setting, especially in urban areas
  • helps reduce stress levels throughout the borough
  • softens and brings colour and character to built up environment
