What to know about Urban Forestry and Infrastructure

Researchers from Florida International University have studied the cooling effects of urban tree canopies in Miami, finding that large, dense canopies provide significantly more cooling than smaller or ornamental trees. The article discusses the importance of protecting mature trees and selecting appropriate species to combat the urban heat island effect.

What happened

Miami's largest tree canopies deliver most cooling, monitoring data suggests Sadie Harley Scientific Editor Andrew Zinin Chief Editor People rarely give much thought to the trees around them—until there aren't any.

Why it matters

But on a sweltering Miami afternoon, when the sidewalk feels like a frying pan and the air itself seems to radiate heat, stepping beneath a tree can feel like walking into a different climate.

Common ground

That's exactly what Florida International University researchers have spent the past several years studying.
