The drive round East Saguaro is called Cactus Forest Drive and at one time really was a saguaro forest.
Saguaro’s are surprisingly delicate and can and do die if the temperature falls below freezing for over 20 hours. A couple of very cold winters in the 20th century killed swathes of them. Mesquite and other desert plants are used as nurse plants and saguaro are now gradually re-establishing themselves.
