Tree species differ in their ability to reduce air and surface temperatures and increase relative humidity. Trees with a high leaf-area density and rate of transpiration are more effective at cooling air temperatures. This Dresden study found that Corylus colurna (Turkish hazel) and Tilia cordata (Little-leaf linden) had the highest cooling potential and Ulmus x hollandica (Dutch elm) had the lowest.
