Dubbo Regional Council has taken out a Local Government NSW Excellence in Environment award for the Dubbo Heat Island Amelioration project. The project will increase shade by 300 per cent. It was lead by council's Ian McAlister.
Council's manager open space and recreation said the elms were ideal for lowering temperatures when the street temperature can reach up to 58 degrees. They tolerate the heat, air pollution and periods of drought.

"Shade from the Japanese elms trees planted in the Bultje Street medical precinct will reduce urban heat along one of the hottest streets in the Dubbo CBD, cooling the road, footpath and buildings," Mr McAlister said.
"The attractive Japanese elm will produce a high broad dome and over time each of the trees will have a canopy up to 12 metres. It is estimated this will increase the percentage of shade in the immediate area by 300 per cent and reduce land surface temperature by 20 degrees."
Bultje Street was identified as a top priority for the trees because of its high heat exposure and heavy foot traffic.
The trees have been planted using water-sensitive urban design principals to capture storm water run-off from nearby streets. It will limit the amount of potable water used on the trees.
