LOL, and we reckon we got it tough with chainsaws and spikes!

Good pics, the very first has a lot to talk about and for street planters to realize.

The red arrows show the weakest axis for windthrow, the green show the stronger.

The yellow show where roots have pretty much failed to go further due to hostile environment.

Now the thing to really wake you up is the likely axis for failure has the higher target value, either houses or cars!

Large tree planting in strips like this is not very wise, yet done a lot. Isolated trees most likely to fail. Remnant trees where roads and footpaths are cut are a sure fire recipe for failure down the track (or die back/death).
