Llama wool?

It's about non-domestic wild animals that aren't mammals, birds, insects, or reptiles.

So... amphibians?

 

[Qactus]

Also not amphibians. You're really close now, having covered almost the entire animal kingdom with the guesses

 

[Valka D'Ur]

Fish?

 

[Qactus]

Fish?

Yes, congratulations!

Number of wild-caught fish killed for food​

This data is based on the average tonnage of annual catch from 2007 to 2016, and estimated mean weights for fish species. It does not include unrecorded fish capture, such as fish caught illegally and those caught as bycatch and discards.

 

[Valka D'Ur]

Thank you. However, I can't think of anything at the moment that wouldn't take more time to research than I have, so I declare the floor open.

 

[Valka D'Ur]

The floor is still open, everyone. I haven't had any good map ideas lately.

OK, how about this one:

Loss of trees ?

Loss of trees ?

Really really close for a first guess, but not quite right.

Wetland coverage?

 

[EnglishEdward]

Loss of peat bogs.

 

[Birdjaguar]

The dark blue trees seem to like to be near water.

 

[Birdjaguar]

Perhaps the inverse of old growth forests. Dark blue represent frequent or recent harvesting and the lighter green closer to untouched?

Not obviously related.

A bit closer
