In this Saturday episode of Talking Trees, we explore how urban trees and green spaces contribute to pollen allergenicity, a growing health concern—especially as climate change alters pollen production patterns.
We discuss:
- Findings from Florence and Córdoba showing how urban park design, plant species selection, and park size influence ground-level pollen concentrations
- Research from Poland evaluating allergenicity in urban parks using plant volume and allergenicity indices
- A new framework for creating regional guides on allergenic tree species, helping planners make better planting decisions
- Insights from a systematic review showing that climate change is increasing the Annual Pollen Integral (APIn), exacerbating allergies across Europe and North America
- Strategies for balancing biodiversity, urban greening, and public health, including allergen-aware urban forestry practices
This episode emphasizes the importance of species selection and climate-sensitive planning to create healthier, greener cities.
