There’s one more reason to love trees. A new study from The Crowther Lab, ETH Zurich, published in the Journal of Science, July 2019, says that targeted reforestation could isolate 2/3 of human-made carbon emissions and would be the best way to mitigate the effects of climate change.

The researchers calculated that under the current climate conditions, Earth’s land could support 4.4 billion hectares of continuous tree cover. That is 1.6 billion more than the currently existing 2.8 billion hectares. Of these 1.6 billion hectares, 0.9 billion hectares fulfill the criterion of not being used by hu-mans. This means that there is currently an area of the size of the US available for tree restoration. Once mature, these new forests could store 205 billion tonnes of carbon: about two thirds of the 300 billion tonnes of carbon that has been released into the atmosphere as a result of human activity since the Industrial Revolution.

Calculations were made based on current conditions and cities and agricultural areas were not included because those areas are necessary to support human life.

According to Prof. Thomas Crowther, co-author of the study and founder of the Crowther Lab at ETH Zurich: “We all knew that restoring forests could play a part in tackling climate change, but we didn’t really know how big the impact would be. Our study shows clearly that forest restoration is the best climate change solution available today. But we must act quickly, as new forests will take decades to mature and achieve their full potential as a source of natural carbon storage…. The study also shows which parts of the world are most suited to forest restoration. The greatest potential can be found in just six countries: Russia (151 million hectares); the US (103 million hectares); Canada (78.4 million hectares); Australia (58 million hectares); Brazil (49.7 million hectares); and China (40.2 million hectares).

I encourage you to check out the Crowther Website where you can read the report in full. The site also offers a tool that allows you to pinpoint any area on the globe to find out about its reforestation potential.

Tree Tuesday

One of my favourite perspectives for photographing trees is looking up, way up, because a tall tree silhouetted against the sky is majestic. In winter their uppermost bare branches create beautiful patterns in the sky that look sculptural to me. Some trees, though, create sculptural bare spaces in the summer, too, through a phenomenon known as “crown shyness.”

If you look up toward certain types of towering trees—including eucalyptus, Sitka spruce, and Japanese larch—you may notice a unique phenomenon: the uppermost branches don’t touch. Known as “crown shyness,” this natural occurrence results in rupture-like patterns in the forest canopy that seem to perfectly outline the trees’ striking silhouettes.

Numerous scientists have been studying crown shyness since the 1920’s and several theories have been put forward, but no one knows for certain what causes it.

One possibility is that it occurs when the branches of trees (particularly those in areas with high winds) bump into each other. Another suggested explanation is that it enables the perennial plants to receive optimal light for photosynthesis. Perhaps the most prominent theory, however, is that the gaps prevent the proliferation of invasive insects.

My favourite theory is the one that postulates the trees are trying to avoid bumping into one another. It seems so polite and I can imagine woody conversations along the lines of “oops – so sorry old chap – didn’t mean to crowd you. I’ll just move over here.”

I think it’s stunning and hope I get a chance to see it someday. If you’re lucky enough see it, please take a photo and share.

Here’s one last photo from the story, but I encourage you to check out the full story and look at all the photos. The link is below.

Embers and the Giants by Canadian artist Kelly Richardson – source CBC Arts

Canadian artist Kelly Richardson loves trees, especially the trees in the old growth rain forests on Vancouver Island where her latest work Embers and the Giants was filmed. Richardson fears for the future of these ancient trees and with good reason – deforestation is happening at an alarming rate and it’s recently been announced that another 109 hectares of pristine forest will be auctioned off.

Richardson’s work may prompt you to consider how we relate to nature as a species and to consider what the future may look like if we don’t choose a different path. In this video made by filmmaker Lisa Wu, you’ll travel to the forest with Richardson and get to see her at work making the landscape come alive in Embers and the Giants. The film was commissioned to participate in the XL Outer Worlds project celebrating the 50th anniversary of IMAX.

Embers and the Giants will be at the Toronto Biennial of Art in Fall 2019, and then it’s travelling both across Canada and internationally. You can find out more about Kelly Richardson and her work here.

I’d like to thank rq for pointing this story my way.

I’ve had the Monkey Puzzle Tree on my list of trees to share with you so I was delighted to receive these photos in our mail this week. It comes from Lofty and it’s a splendid specimen.

An interesting tree that was planted in a local park over 100 years ago, a South American “Monkey Puzzle” tree.

The tree was given the name “Monkey Puzzle” in about 1850 by a British Barrister named Charles Austin who remarked upon seeing the tree in an English garden “It would puzzle a monkey to climb that.” The tree had no common name at the time and so monkey puzzle stuck. The tree is a long-lived conifer and is now cultivated in temperate zones world-wide. Unfortunately, in its home range of South America the tree is on the Endangered list because of logging and fires. – source: Wikipedia

Thanks Lofty. Your timing was spot on.

Once or twice a year I get down on the forest floor to take a few photos of the tall trees in our wee Carolinian Forest. I love the perspective. I’m not the only one it seems who like to look up. Italian photographer Manuelo Bececco has created a stunning group of forest photographs by pointing his camera up.

“In the middle of the woods, I seem to see everything in my own way—giant trees or branches that form barriers, irises of the eyes,” Bececco tells My Modern Met. “These are things that I only see in my mind and that I can sometimes turn into photographs.”

Photographed across different seasons and different times of day, the forest’s changing ambiance is expertly harnessed by Bececco. The Italian photographer is able to use the light, and the mood it generates, to his advantage and capture a mystical moment in the quiet of the woods. This forest photography is deeply personal for Bececco, as each photograph is inspired by an important time in his life. And for him, it’s been a pleasant surprise to see how well it’s been received by the public.

I’ve included a few of his photos here to whet your appetite, but I encourage you to check out the link at My Modern Met to see the entire grouping. Mr. Bececco has captured not only the many moods of the forest, but also the deeply felt emotions that being amongst such giants elicits. My thanks go to rq for pointing this story my way.

Tree Tuesday

One of our readers has recently moved back to Canada from Mexico and they’re missing the blooming of their favourite tree, the Royal Poinciana also known as the Flamboyant Tree. It’s easy to see why the these trees would be missed. Many people consider the Royal Poinciana to be the most beautiful flowering tree in the world. Native to Madagascar the trees were introduced to Mexico in the 19th century and quickly came to be loved.

In Yucatan, these beautiful flowering trees became favorite ornamental trees to grow near Mayan huts, villages, urban avenues and parks.  Its orchid shaped deep orange-red flowers are truly exquisite, one petal is different from the rest with light tone and deep shades of orange magenta spot; flowers grow in clusters, blooms in May and summer the Flamboyan trees are fully covered with flowers without their pinnae leaflets (foliage). Flamboyan seeds grow in large “machete like” hard pods.

Mexico is only one of many warm climates where the Flamboyant tree has prospered. According to Wikimedia the Royal Poinciana is now successfully cultivated worldwide in tropical and sub-tropical regions.

The blooming of the royal poinciana is certainly an event to be celebrated as its flowers are large, bright and plentiful.

The flowers of the royal poinciana are large and normally a shade of yellow, orange, or bright red. Each flower has four spreading petals that measure up to 3 inches (about 8 cm) in length and a fifth petal called the standard that is upright and a little bigger than the other petals. The standard is distinctive because of its white and yellow spots. Another common name of the royal poinciana is peacock flower because the physical appearance of the flowers is similar to that of a peacock with its feathers up.

Because of its size and wide umbrella shape the royal poinciana is an excellent shade tree and is beloved wherever it grows. There is also research being done that shows the plant has much more to offer than just beauty and shade. Studies have found anti-microbial and anti-inflammatory properties along with an ability to increase wound healing and aid in glucose tolerance in diabetic mice. If you’re interested, the article linked below at the Liliana Usvat blog also offers information on the propagation of the tree and the current research studies being done on the plant.
