Why trees: The natural world

Trees and woods provide important habitats for wildlife, and are essential to our natural environment.

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)
  • Boost biodiversity - On average, 70 percent of the plant species and 94 percent of the bird species found in urban areas are native to the surrounding region (3)
