When we explore other planets and wonder if life could have existed there, it is not carbon or silicon or even amino acids we look for at first. We look for water.
Without it, so far as we know, life is not possible. This is not to say that biotic entities cannot survive in dormancy for long periods–hundreds of years or longer–in a dehydrated state. Tardigrades are champs at this.
But for the most part, access to water is the limiting factor for land creatures and all aquatic–salt or fresh–plants and animals.
Closer to home, it turns out that forests are pretty good at finding available water, even from fissures underground. And given Floyd County’s fractured rock, the fact that this can be a source of survival water during times of drought gives a bit of comfort.Â [click image for source article/ Berkeley News. ]
I will be meeting with some spring-breaking students from U of Del next week at Apple Ridge here in FloydCo to have a discussion about water in the Blue Ridge, and this is one of the things we will talk about.
And given my current need to stay focused and not get too sidetracked, if and when I blog, it will generally be from stuff I alreadyÂ have on hand related to what I am working on at the time. So fire me.
I read the article. Very interesting. Douglas firs are increasing in northern California and they may be why stream flow is decreasing in the summer. They are harvesting the rock water that otherwise would go into streams.
