Your...

 

Are there any plants that still grow in this desert? Yes.

 

Some plants have developed a growth mode quite appropriate in the circumstances: they try to grow faster than the sand takes to recover them. Fascinating!

 

 Made me remember...

 

Migrating Vegetation

 

 Is a common phenomenon on high, windy slopes and is illustrated by the drawings (below) of the Rocky Mountain limber pine.

 

A slaping takes root on the lee of a protecting rock, then begins to put out branches (2) which, bent downward by the wind also take root. Each winter all of that years upward growth unprotected by the snow (3) is killed by cold dry winds.

 

                                        

 

Eventually the old parts of the tree begin to die, (4) but still serve as protection, taking the place of the rock and permiting the tree  to continue its migration. (5).

 

 

 

I recall thinking when I read this...how much could be the plant desire to move from here to there...as the animals...desire...generates evolution...
