desert and sub-tropical regions - Computers, Math, Science, and ...

The Sahara does have Oasis.

Both natural, and manmade, irragation can create a garden spot in the middle of a desert in which you can almost have one foot in each vegation zone.

So I would say it can happen. Camel caravans depend on it actually.

The opposite- a pocket of desert in a wet zone happens too. You can have a rain shadow caused by mountains blocking the prevailing winds and forcing rain to fall before it reaches the valley on the lee side. Thus making the valley a desert ( its common in the state of Washington). But you couldnt do that within one quarter of a mile. The mountains have to be thousands of feet high and miles broad for that to work.

So you can have oasis in the middle of a desert in that small a space. But you cant quite make a pocket of desert happen in a larger forest in that small a space.
