Description

Groups of trees mimic the gestalt of a forest in an urban setting. They can be a suitable option for the design of shaded squares and courtyards, or as a contrasting element in densely built up areas. Urban groups of trees offer many benefits like improved water management and climate resilience, and contribute to the mitigation of urban heat stress. Additionally, selection of diverse, native species in combination with understory vegetation can help support and enhance biodiversity.

Conditions for Implementation
  • Appropriate species selection
  • Sufficient above and below ground space
  • Soil material and depth
  • Temporary or permanent sustainable irrigation facilities
