Is this monkey puzzle dead?

Hello,

We have two Monkey Puzzles in our front lawn. I think one of them is dead but I'd rather be sure before I get a digger in to take it out. Can anyone tell from the photos if it's dead?

The last photo is of the second monkey puzzle. There's still a bit of green on the top so I'm guessing it's still alive!

 

If there's green there's hope.

 

I only see green on one. Does that mean that there's no hope for the other?!

 

With conifers, red = dead.

 

:( maybe this is like asking "how long is a piece of string" but how long is a dead monkey puzzle expected to stay standing?

 

Cracking of the soil near the bottom after winds can be a hint that it is starting to come loose.

 

In Native Chili, the trees may grow to 30 to 40 metres, yet loose all their lower limbs way up to the crown head, shame if they have succumb to pollution.

 

A bit worrying that two of the young ones also look dead or nearly dead. I'd suspect some soil-borne fungal disease, such as Phytophthora; the recent wet summers could have left the soil waterlogged, which encourages fungal diseases.
