Tree Species Selection for Green Infrastructure

Talking Trees

In this Wednesday episode of Talking Trees, we explore how thoughtful tree species selection is essential for building resilient green infrastructure in cities facing climate change, soil limitations, and urban stressors.

We discuss:

• Why tree selection should be based on site-specific conditions, including soil compaction, heat exposure, and rooting space
• Tools and frameworks for choosing species, including guides that rate trees by drought tolerance, flood resilience, and ecosystem service potential
• The importance of species diversity to reduce vulnerability to pests, diseases, and environmental extremes
• Lessons from trees thriving in natural habitats and how they can inform urban planting strategies
• How properly chosen trees can enhance urban cooling, air quality, stormwater management, and long-term canopy cover

Species selection isn't just a design decision—it's a foundational step in ensuring that urban trees survive, thrive, and serve.
