Is this tree dead?

It does look like substantial ribs of reaction wood have grown on both sides of the cavity. As targets (persons and items of value which might be impacted by the tree or parts of it in the event of failure) seem to be negligible, the overall risk (based on the photos) appears to be low. Reduction pruning to reduce end weight and height, could further mitigate the risk of failure.

Liberating the tree and its neighbor from those boxes, and pneumatic excavation to remove soil to expose the root flare and to decompact the soil may help the tree to enjoy better vitality.

The very first image shows the classic" tree suffocated by concrete" image that always concerns me. Raked yards, gravel and paved walk/ driveways. None of this promotes healthy plants. Bad or no drainage, bad or no aeration, no duff layer- the only decomposition taking place is the starving tree. Trailer / RV parks are notorious for this. They don't want to pony up for aeration, fert or irrigation and expect these trees to magically live on nothing? Can't understand it?

That's my rant, if these trees were human beings they would be sick and diseased people and the first injury they got would likely kill them.

Thanks for helping out everyone!

Backstreet has some great initial information.

You guys are great. Thank you!

Regarding the planter boxes - would you suggest removing them? Taking out some of the soil? Filling them with mulch?

Remove them. Take out the soils. Put mulch over that area that will be level with the driveway/rest of the yard. Mulch should only be 2-3" deep.

Also bear in mind that when trees get bigger they may crack the concrete.

The tree is its own target. Good advice by all.
