Trees provide hundreds of millions of dollars in services to cities for free, paper reports


Trump Forest wants to compensate for the POTUS’ climate policy by planting 100 new billion trees

Nope, it’s not Trump’s idea.

How old is the oldest tree?

it’s a surprisingly long time.

We can’t count on trees to solve our global warming mess — there’s just too much CO2 out there

We’d have to plant trees instead of food.

Up to 80 percent of all wildfires in the U.S. are started by humans

Wildfires are generally good for forests but the current trend is anything but natural.

The different types of forests: everything you need to know

The green lungs of the earth come in many different varieties.

Mindblowing fact of the day: sharks are older than trees

That’s seriously badass!

Scientists use sound waves to ‘listen’ for decay in trees

The longer a sound wave takes to transverse the trunk, the more decayed the tree is.

Gold growing on trees offers a new prospecting tool

Who said money doesn’t grow on trees? Take this grandpa!

“Extinct” elms discovered doing just fine in the Queen’s gardens, Edinburgh

It’s good to be Queen. But it’s even better to be the Queen’s elms.

Douglas fir forests are buckling under the heat, pausing their growth altogether

Silly trees, can’t they set the thermostat lower, like the rest of us?

Trees trade carbon through their roots, using symbiotic fungi networks

A forest’s trees capture carbon not only for themselves, but also engage in an active “trade” of sorts with their neighbors, a new study found. University of Basel botanists found that this process, conducted by symbiotic fungi in the forest’s soil, takes place even among trees of different species.

Europe might lose its ash trees forever

Europe is likely to lose all its ash trees, the largest-ever survey of the species warns. Plagued by both a fungal disease known as ash-dieback and an invasive species of beetle, the emerald ash borer, the tree might be wiped clean off of the continent.

Surreal crooked trees shaped by Antarctic winds

Wind gusts are so unforgiving that the trees themselves molded into weird and crooked shapes. There’s an almost surreal beauty to their shape, though — it brings harshness to life. You won’t find anything like it anywhere else in the world.

Oddly enough, all trees regardless of size break at the same wind speed

In the wake of calamities like hurricanes or tornadoes, you’ll find trees leveled to the ground. But observations suggest that all trees seem to break at the same wind speed, with parameters like the type of tree, height or diameter barely affecting the outcome.

Dutch collective plans to “plant” a forest on Rotterdam’s waters.

Where do we find the space for trees in our cities with all the buildings already vying for the limited space available? Dutch collective Mothership’s answer is waterways. The group plans to install the “Dobberend Bos” (Bobbing Forest) in Rotterdam’s Rijnhaven harbor next spring.

Crown Shyness – Trees can shy away too!

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.

EX-NASA Engineer Wants to Plant one Billion Trees a Year Using Drones

Each year, we cut down 26 billion trees, for lumber, agriculture, mining and development projects. Every year, we plant about 15 billion trees, so that still leaves us with a huge deficit – something which is not sustainable and has to be addressed as soon as possible to avoid further problems down the road. Now, a former NASA engineer has found that drones could play a key part, and he plans to plant up to 1 billion trees a year using them.

California lost half its large trees since 1930, steep decline continues

California’s large trees or those larger than two feet in diameter have declined in numbers to half that recorded in a 1930 census, according to a study published in Proceedings of the National Academy of Sciences. The leading cause of the demise is thought to be rising surface temperatures which but high stress on large trees, along with water shortages.

Tree rings reveal worst droughts in the West’s history happened during Christopher Columbus’ lifetime

Modern climate tracking and water flow records go back only 100 years, but to prepare for the worse, scientists and policy makers alike need to understand how the weather was like in the world many more years prior. A solution is to study the tree rings of certain tree species which bear telltale signs of water levels hundreds of years past,
