Crown shyness

What an interesting word. 😀

“Crown shyness is a phenomenon observed in some tree species, in which the crowns of fully stocked trees do not touch each other, forming a canopy with channel-like gaps.“

How do the trees know not to touch each other?

Nobody knows though it’s been studied since the 1920′s.

Looks like distant rivers in the sky! Beautiful

in finland’s riisitunturi national park, siberian spruce trees become covered with tykky, a hard rime formed as supercooled water droplets in fog freeze to the windward side of the tree branches. some trees can collect as much as three to four tonnes of this white ice, which is less dense than the familiar clear ice. photos by (click pic) eki ollila, sara winter, pekka koski, rafael rojas, and hanneke luijting
