Today, we drove about 100 miles to get to Saguaro National Park just in time for the next viewing of the video of desert wildlife and creatures. Although we knew that the rainfall amounts were very slight, the vegetation is able to adapt to the lack of rain. The Saguaro Cactus for example has one tap root that goes down usually more than 2 feet, and a system of very shallow roots that go out as far as the plant is tall. It also can swell to accommodate more water being taken to help it survive long dry spells. This particular cactus was taller than most.
They top out around 40 feet or so. To give you an idea, Grammie helps to measure up the tree.
When a Saquaro dies, the central part of the tree consisting of wooden tubelike structures is all that might remain. One thing we learned is that a younger cactus will often survive growing up around a tree, getting water from what the tree might attract. Usually the tree dies but in this case, the cactus didn't make it.
One might think that deserts are usually dry...and they are but the Sonoran Desert has nearby mountains that help supply it with water.
The Saguaro National Park is near Tucson. You can see homes in the back ground .
We happened to miss a trail on the way up which extended our hike to about 5 miles.
Grammie wanted a picture of a Prickly Pear Cactus.
We decided to stay overnight in Tucson so we can see more things tomorrow.
As always, thanks for wondering where Grammie is in her travels.
