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).

| Re: Found any neat pics? Street tree failure diagnosis Wow! The ground must have been realy wet for those root plates to pull up like that! The Ol' boy looks like he's doing the best he can with what he's got! There's alot of people in my area that leave P.P.E. in the truck & some of them don't even tie off! |

| Re: Found any neat pics? Street tree failure diagnosis Notice how flat and sheer the soil and roots are where it met concrete? Not only is it the concrete but the compacted road base beneath. Then highly likely a soil layer beneath of harder or different profile, like shale or clay etc ... so the whole lump goes over. Like the tree's stability is similar to a mafioso in concrete boots.
