This article should do two things:
1. Start the alarm bells ringing if they're not already and
2. Convince us all the more that the place to have the majority of our urban forest is on public land.
Because you can control what happens on public land. Private land, not so much.
And streets are still hugely under-utilised public land when it comes to urban forest. I reckon I could count up thousands - probably tens of thousands - of gaps in the street street plantings of every suburb in Perth. That's millions of trees just waiting to be planted. No permission required. No planning scheme amendments to make. We can do it NOW.
And the other beauty of street planting in particular - assuming you use big enough trees - is that you shade the roads - those long, black thermal radiators that turn our city into a "heat island" every night.
Actually, the article should do three things. It should also make us thankful for the work of this mob.
More power to 'em.
