Heatwave conditions in newer suburbs linked to lack of trees

Published Dec 13, 2024, 2:00 AM

The heatwave conditions are made worse in our newer suburbs, where a lack of shade trees is being blamed for sending the temperature soaring. While councils are starting to demand tree canopies increase, there are calls to make new housing developments retain existing trees and plant more new ones.

For more, Lucy Murray reports.

This is the Australian dream. In twenty twenty four, no gardens and no trees On average, Perth has the smallest blocks for sale in the nation and there's some of the hottest. The government is working on the first ever tree canopy code, but the Minister wouldn't be drawn on the detail.

It is that fine balance. We need as much housing as we can, but of course we also want to see trees planted throughout our suburbs to provide that necessarily cooling for streets.

Trees are the air conditioners of our suburbs. They are the critical element for keeping places cool.

Wa developers are only required to sent aside ten percent of land for public open space, and there's no requirement to keep any existing old trees.

That is going to lead to a disaster in Perth if we don't build with tree as a major component.

The science shows suburbs with trees around to eight degrees cooler than those without.

I think there's a real opportunity in using public land so primary school sides road corridors.

Right now in Brabham it is a scorching thirty nine degrees and it's not just because we're inland on the coast in Alcamos is thirty eight degrees. That's another new suburb with very few trees. But if you go to the leafy western suburbs in Clermont right now, it's ten degrees cooler, just twenty eight. But the blocks in Brabham are selling like hotcakes, even if the residents prefer to stay indoors.

Definitely, the air conditioning is going to be on a arm.

I think you could always have more trees.
