nurse tree or shrub
![Name](images/saquaro3.jpg)
The Saguaro can grow as high as 50 feet and weigh 6 to 8 tons
![Name](images/saquaro4.jpg)
A Saguaro will be 65 years old before it forms its first arm

The largest Saquaros, with more than 5 arms, are estimated to be 200 years old
![Name](images/saquaro6.jpg)
The arms can number over 25

The Gila Woodpecker and the Gilded Flicker make their home in the Saguaro Cactus by chiseling out small holes in the trunk
![Name](images/saquaro9.jpg)
Once they leave, they don't re-use the same nest, but other birds do, such as owls, finches, cactus wrens and purple martins
![Name](images/saquaro15.jpg)
The Saguaro is smooth and waxy but the ribs have clusters of stout, 2-inch spines
![Name](images/saquaro16.jpg)
When the Saguaro absorbs water, the outer pulp can expand like an accordion, increasing its weight by up to a ton
![Name](images/saquaro17.jpg)
The Saguaqro can cover a wound with a resin-like substance which hardens into a permanent scab. These hardened holes are called "boots."
![Name](images/saquaro18.jpg)
Mostrose Growth: The Saguaro develops a crest instead of arms. When damage caused by frost, insects or other factors disrupts the apical meristem.

When a Saquaro dies its rib wood is lightweight but strong and has many uses.

Because this cactus has no arms, it may have died young. Causes of death can be frost, insects or lightening.
![Name](images/saquaro22.jpg)
Native Americans used rib wood to make drill sticks for making fire, crosspieces for baby cradles, splints for injured limbs and as wattle in the construction of wattle and daub houses

After dying, a Saguaro still offers a place for birds to nest
