New research details impact of extreme #wildfires on #PineTrees

By Allie Ruckman

"It’s known that wildfires have adverse effects on humans, but what about the plants, animals and trees?

"New research by Mj Riches, a postdoctoral research fellow in the Colorado State University Department of Chemistry, found that poor, smoke-induced air quality affects ponderosa pine trees’ ability to maintain #photosynthesis and release natural chemical emissions. Riches estimates a 7-14% decrease in ponderosa pine growth rate due to heavy smoke."

Good morning. 🌲🌲🌲

Happy Juneteenth!

For those of you around the world, who don't know, Juneteenth is an American holiday that commemorates the emancipation of enslaved African Americans. It's a relatively new Federal Holiday but the holiday itself has been celebrated for a long time. The below quote explains in more detail. I couldn't fit it all in this toot so I included the entire URL for those who want more information.

"Juneteenth (officially Juneteenth National Independence Day) is a federal holiday in the United States commemorating the emancipation of enslaved African Americans. Deriving its name from combining June and nineteenth, it is celebrated on the anniversary of the order by Major General Gordon Granger proclaiming freedom for enslaved people in Texas on June 19, 1865 (two and a half years after the Emancipation Proclamation was issued)." - en.wikipedia.org/wiki/Juneteen

This photograph is unintentionally black and white. It is one candle (new growth) from a pine tree with pine needles radiating out in all directions. There are some others in the lower right corner. The photograph is presented as a vignette, so the outer edges and corners are progressively lighter than the subject.
