This Claret Ash has died because the resident is about to demolish the house and has turned off the irrigation to the verge.
In this post I talked about how we can use temporary irrigation to tide trees over in this situation but, long term, is it really sustainable to rely on trees that rely on irrigation? A truly resilient urban forest is one that can survive on natural precipitation alone.
Here's how we can build it:
- Residents give their verges back to the council
- Only trees which can survive on natural rainfall are planted
- Multiple trees are planted per verge so that the forest becomes self-mulching
- No other planting on verges is allowed (takes moisture from the trees)
- No irrigation of verges is allowed (makes the trees dependent)

It would look something like this.
This then is the vision not of a forest in the city, but a city in the forest.
It's the vision the City of Melbourne has already articulated and is working towards.
I think we should too.
