What the lichen growing on Oregon's trees can tell us about air quality | Oregon Field Guide

I am a lichen nerd, love them. Thanks, very nice

I'm the producer and yeah, me too. #lichennerd

My undergrad is in ecology and I studied lichen pretty indepth. I'm super excited to see more studies on this amazing indicator species! Its really shocking to me how under studied it is, and I believe there are lots of secrets they hold! ❤

I moved to Oregon recently from SoCal and have fallen in love with the lichen I see! It makes everything look so enchanting

I recognize the coral reefs of the air.

They ARE beautiful

I learned something today.

Lichen and mushrooms, two of my favorite things. Oh, and moss. Didn't know they tell pollution levels.

[@thePrisoner1000]

Very interesting, more please!

[@AlphaqueUp333]

The video doesn't go into any detail on the process that occurs when the lichen is exposed to higher levels of pollution. What pollutant is the cause of the changes?The only thing said was that it has to do with nitrogen? Is it impacted by an imbalance of nitrogen in the air (off from the standard 78% normally found in the atmosphere,) does it have to do with exposure to NOx, or is it something else?

"There are huge non climate effects of carbon dioxide which are overwhelmingly favorable which are not taken into account. To me that's the main issue that the earth is actually growing greener. This has been actually measured from satellites the whole earth is growing greener as a result of carbon dioxide in the atmosphere. So it's increasing agricultural yields, it's increasing the forests, it's increasing all kinds of growth in the biological world and that's more important and more certain than the effects on climate." ~Freeman Dyson, Institute of Advanced Study in Princeton, New Jersey.

NEED TO WORRY ABOUT THE LICHEN GROWING ON THE STREETS

[@theresamcmullen4841]

Corals of the air.

[@bryancommeree1829]

i prefer to pronounce them differently than like the werewolf pronunciation...

Look at a dog turd under a microscope: same thing happens.
