Ben's Project Findings
Why don’t California Fan Palms grow natively in Tucson even though they are native to Arizona?
I learned palm trees in Tucson take a lot of care, and some people think they are a problem for Tucson because they aren’t native. I started researching palm trees in Tucson and learned about the California fan palms (Washingtonia filifera). It's the only palm tree that is native to Arizona. They grow in Palm Canyon at Kofa National Wildlife Refuge near Yuma.
I started my experiment by going to Palm Canyon.
I compared the conditions there (elevation, direction, pH, light, moisture, nitrogen, potash, phosphorus) and compared them to where other palm trees grow in Tucson to see if any conditions are different.
- The notable differences were that in Palm Canyon the moisture level of the soil was higher and the light level was lower.
- The information gained from the experiment will help people learn that the conditions in Tucson don’t support palm trees’ needs without additional care.
I hope my project will encourage people to plant native desert plants instead of palm trees in Tucson.
