Virgin River Restoration in Zion National Park
Cottonwood trees are not reproducing in Zion Canyon because of a levee (aka revetment or rip rap) installed during the late 1930s to prevent flooding. Turns out that cottonwoods reproduce by dropping seed on wet soil from spring floods. So the flood protection project eliminating cottonwood reproduction. The remaining trees are getting old as they all date back to before this project. In 2001 I led a study, under the auspices of Grand Canyon Trust, to analyze the problem and develop restoration alternatives.
Here I am in May 2016 shooting video while standing on top of the problematic revetment. The river is on the left and the floodplain is on the right, clearly separated by the revetment.
This video describes the problem with the trees in Zion Canyon:

Freeport, MaineI decided to purchase the Urban Defender for whole-house filtering and a reverse osmosis unit for drinking water (I live in Los Angeles).
It is hard to explain the sense of satisfaction and safety I feel knowing that the water I bathe in and drink is healthy.

Los AngelesI couldn’t stand the smell of cooking odors in my home. Now, within 15 minutes of cooking, the odors are gone. Also, I have always had allergies. They’re not bothering me anymore either. I love this machine. It works. It’s worth every penny. I like it so much…..

Los AngelesThe iron system is fine; our water is clean and the toilets aren’t stained. My bride is happy! As a matter of fact, the system seems to have had a softening effect on our water – a fringe benefit we hadn’t expected but are happy to have.
