Botany Photo of the Day
In science, beauty. In beauty, science. Daily.

Pinus longaeva

Pinus longaeva

In its high mountain habitat, Greast Basin bristlecone pine is subject to weathering from ice crystals and dust, particularly from the direction of the prevailing wind. On the side of the tree away from the wind, the individual continues to eke out an existence, but on the side of the tree facing the wind, the trunk tissue is subject to a “death by a hundred million cuts”. This abrasion over hundreds of years will first wear away the living tissue of the trunk and then begin work on polishing and sculpting the dead interior wood, as is shown in today's photograph.

MOST INTERESTING.

I was curious as to what in heck the photo was, and it was not even close to what I suspected.. an arial view of a peculiar forest, ha ha ha.

Apparently the tree is still living on the other side, so it must be very strange, and very hardy to withstand such weather. Amazing.

Adriel commented:

Wow, that's cool.

I thought we were looking at a fossilized something or other.

sinagua commented:

In bonsai, there is a word for a part of the tree that has died, but because of its beauty they don't cut it off, but leave it, and it enhances the tree's overall aesthetic beauty...sure wish I could remember that word. Great photo and a great entry.

Bobbie commented:

Robin Winburn commented:

Knox commented:

If the weathering is so severe, how does the tree manage to grow and generate a layer of bark on the windward side that can eventually be subject to fissuring by the weather ?

larry commented:

The Bristle cone is also one of the oldest dated species, I believe one in Colorado has been dated at 3500 years old

Trudy Anderson commented:

Actually, there are 2 Bonsai words. If the dead wood is on the trunk it is called shari. If it is a branch it is called jin.

Margaret-Rae Davis commented:

Looking at this photograph it does seem to be anything alive. Very interesting.
Thank you for a new learning esperience.
