Old Trees Help Young Trees Grow

August 1, 2011

/ This is amazing /. “Mother” trees sharing nutrients and water with daughter trees.

For young trees, “increased survival was associated with belowground transfer of carbon, nitrogen and water from the old trees.”

Yet another reason never to clearcut. We shouldn’t need reasons for avoiding such an obviously destructive act, but unfortunately, logging companies want money. Clear cutting is fast and easy compared to judicious pruning, and then replanting a natural forest in the gaps rather than a one-species orchard.

Interesting: a healthy forest, like a healthy society, depends on both age and youth, diversity in its population, sharing resources, and those with experience and skill helping those who lack either or both.

What we keep learning about our world, about  life of all sorts, including ourselves, never ceases to astound me. And yet there is so much left to learn.

I appreciate the importance of this post from / Cosmic Variance / on our real knowledge of the basic laws of physics. We need to remember how much we already know. That knowledge gives us the tools to learn more. I include / this link / to Sean Carroll’s follow-up article because of this sentence: “Today we think of ourselves and the stuff we see around us as made of electrons, protons, and neutrons, interacting through gravity, electromagnetism, and the nuclear forces. A thousand years from now, we will still think precisely that.”

The joy of discovering and understanding something that was not just a mystery, but completely unexpected yesterday — that is one of the greatest joys we can experience.
