Black Mangrove

This seems to be a test project in Kuwait.
This area wasn't mentioned on the Site I found, but I am taking a wild guess.

In this post the mangroves are (from what I can tell) fairly healthy.
Check this post to see what they look like 8 weeks later.

Not sure what it's caused by (too much heat most likely, but maybe pollution in the water)
I hope they'll recover.
