Why trees: The natural world

Trees deliver a whole range of benefits, which make them an essential part of the future of any city or town. From providing essential habitats for wildlife, as well being essential to our environment – the arguments for trees are clear.

Trees and urban greening play a key role in:

  • Creating wildlife habitats – Trees in urban areas provide important habitats for British wildlife. They encourage biodiversity, with many species relying on woodland cover to survive (1)
  • Supporting species - A mature oak tree may host up to 423 different species of invertebrates (2)
  • Bringing people together – Trees and woods can help to bring people together and strengthen communities, reducing loneliness and isolation (3)
  • Connecting us back to nature – Humans are hard-wired to need connection with nature and other forms of life. Trees and green space help to re-enforce this important link (4)
  • Creating community connections - Green space offers possibilities of increased social activity; improved community cohesion and local attachment; and reduced crime levels, particularly in deprived communities (5)
