Should I say?
We use "The" with deserts, forests, so can we add the word "Desert, Forest" to the back and do we need to capitalize the first letter of "Desert, Forest"?

Ex:
The Congo Rainforest, The Congo rainforest.
The Amazon Rainforest, The Amazon rainforest.
The Amazon Forest, The Amazon forest.
The Sahara, The Sahara Desert, The Sahara desert.

Thank you!

I'm not an expert but I think that both forms could be good. In my opinion it depends of the case or situation - but I can be wrong.
