Plant Adaptation Makes For A Very Diverse Sonoran Desert   6 comments

Being able to adapt is fundamental to all organisms to survive in their ecological niche or habitat. This ability is often more evident in harsh environments such as the desert. Plants need water and sunlight, some more or less than others.

Here in the Sonoran desert, plants that can adopt to a lot of sun and little water adopt well to the hot, dry conditions. While plants needing more water have adapted to conditions near water, i.e., riparian areas where annual foliage plants color the desert at this winter solstice time of year.

Another example of plant adaptation can be found on rocky canyon wall facing the north in Sabino Canyon, just a few hundred feet from where the above photo was taken — there is no direct sunlight this time of year. Even in dry conditions, the wall can provide a perfect hitch for fern, moss and “resurrection” plants.

However, what really caught my attention was a small saguaro cactus that was growing out of the north canyon wall, which had fallen over and has continued to grow. Given the size of the plant and the fact that saguaros are very slow-growing plants, taking 6-7 years to grow an inch in the beginning of what can be a 200 year life, this still small cactus is probably about 20 years old — talk about plant adaption.

This guy is a real survivor!

P.S. Today we are getting much-needed rain in the desert with snow above 4,000 feet. The ferns, moss and resurrection plants will really green-up over the next days.

Strike It Rich — Sabino Canyon Geology Kit   8 comments

Naturalist, Gwen Swanson, Demonstrates “Panning” to Students — Image by kenne

The Sabino Canyon Volunteer Naturalists (SCVN) training includes many topics important to Sabino Canyon and the Santa Catalina Mountains in southern Arizona. One of the topics is the study of Earth’s history. Over time, the region has undergone geological changes that have made the canyon what it is today. 

Yesterday, I observed fifth-graders participating in the SCVN activity, “Strike It Rich,” conducted by naturalist, Gwen Swanson. The creekside activity allows children to learn about difference between rocks and minerals by panning for garnets and magnetite in the sand, and the importance of water in forming the canyon. 

One of the things unique about Sabino Canyon are its banded cliffs. Students learn that these beautiful formations are composed of a hard metamorphic rock called “gneiss,” which formed 1.5 billion years ago. In the Strike It Rich kit, students see example of minerals and gneiss. After the panning activity, the naturalist leads the students on a nature walk where they see the geology of the canyon, pointing out examples of gneiss.

Sabino Creek Is Dry — Almost!   13 comments


This was Sabino Creek on September 14th . . .


. . . this was Sabino Creek, October 27th. There was a nice flow after late monsoon rains in September, but as noted in this morning’s Arizona Daily Star, “A brief autumn dry-up of the stream is not uncommon after monsoon rains end. But this year’s rains were sketchy in the canyon, and the forecast shows no promise of moisture to turn the flow on again anytime soon.” (Click here to read more.


The creek has been without a flow since mid-October, making it a little difficult for the Sabino Canyon Volunteer Naturalists (SCVN) to conduct one of their elementary school children activities, “Creek Critters,” this past week.


However, a few ponds of water remain, so the schedule of activities along the creek continued.

There was plenty of water for the kids to have fun learning about the unique aquatic and riparian habitats in a desert environment. Few things can out do a day in Sabino Canyon, water flowing or not!

Animals Blinding In   1 comment

Clark’s Spiny Lizard In A Tree Near The Sabino Canyon Riparian Area — Image by kenne

Animals blend (camouflage) in with their environment so that others might overlook them. The ability to adapt to the surroundings is natural camouflage, which helps an animal hide itself from predator and prey.

The above photo is of a Clark’s Spiny Lizard, who’s normal habitat is not normally in trees, but see how he blends in.

Another example is the red-spotted toad pictured below. The ability for each to adapt to their environment increases chances of survival, and its chances of reproducing.
