Renaturalization and Habitat Creation

For long-term ecological benefits, parks should promote the renaturalization of landscapes and the creation of habitats where wildlife can thrive — while also considering the impact of vegetation on people with allergies and sensitivities.

Park with naturalized areas that include zones of continuous flowering, natural materials for wildlife, sunken spaces to retain water and where leaves are allowed to fall.
  • Sink areas of the park to retain rainwater naturally and support hydrophilic native plant species.
  • Create microhabitats using logs, rocks, and other natural materials to provide shelter for insects, birds, and small mammals.
  • Avoid excessive removal of fallen leaves, as they help nourish the soil and protect it from erosion — but manage their accumulation in high-traffic or allergy-sensitive areas.
  • Design flowering zones that support pollinators like bees and butterflies, using plant species with staggered blooming periods to reduce heavy pollen exposure at any one time.
  • Select wildlife-friendly plants that are also low in allergenic potential, balancing ecological function with user health.
  • Use buffer zones or distance planting strategies to separate high-pollen species from pathways and rest areas.
  • Encourage a mosaic of vegetation types and blooming cycles to support biodiversity while minimizing allergy peaks.
