A really innovative study that went beyond statistical association and actually planted trees in low-tree neighborhoods and measured the impacts.

>After the plantings, the research team reassessed residents' health. They found that those living in the greened area had 13-20% lower levels of a biomarker of general inflammation, a measure called high-sensitivity C-reactive protein (hsCRP) than those living in the areas that did not receive any new trees or shrubs. Higher levels of hsCRP are strongly associated with a risk of cardiovascular disease and are an even stronger indicator of heart attack than cholesterol levels. Higher CRP levels also indicate a higher risk of diabetes and certain cancers.

>A reduction of hsCRP by this percentage corresponds to nearly 10-15% reduction in the risk of heart attacks, cancer or dying from any disease.

>Although several previous studies have found an association between living in areas of high surrounding greenness and health, this is the first study to show that a deliberate increase in greenness in the neighborhood can improve health.

>A complaint lodged with the government alleges that Argentine provincial officials and businessmen are profiting from clearing the native forest.

>In northern Argentina, lush, green spaces of forest give way to wide, open clearings. In aerial photos, the contrast couldn’t be starker: treetops with varying tones of green, and next to them, brownish empty land. Such is the reality for some parts of the province of Chaco, home to a part of the Gran Chaco, the second-largest forest in South America, after the Amazon. This vast dry forest has one of the highest deforestation rates in the world, losing more than 130 square miles every month.

> It’s long been thought that soil is the only effective terrestrial methane sink, as certain microorganisms use methane as a food source, but similar creatures live under a tree’s layer of bark, meaning that not only do our woody cousins withdraw CO2 from the atmosphere and store it in their roots, but also remove methane as well, about as effectively or perhaps more so than soil.

Years ago, I took an online course on mountains, and one fact that stuck with me from it was about how people in the USA accidentally polluted the water in New York City by cutting down trees.

It was the 1800s, and the trees in the Catskill Mountains were cut down to accommodate growing populations, and as a result, the water quality for New Yorkers deteriorated rapidly. Yes, the agriculture pollution and sewage did play a part, but the trees were decided to be such a big problem, that they decided something had to be done.

So, they purchased land, and planted 18000 trees to restore the natural ecosystem.

How does this water-cleaning work? With watersheds.

> “Watershed: an area of high ground from which water flows down to a river” | Cambridge Dictionary

Imagine it is raining in a forest. Droplets hit the ground, and —thanks to the vegetation which slows runoff — it is absorbed into the soil like a sponge. As the water moves through the soil, microbes are actively removing harmful pollutants, silt is filtered, and plants removing fertilizers.

Some of the water will end up in our lakes and streams, but will be much cleaner than when it started.

> "The ability of forests to aid in the filtration of water doesn’t only provide benefits to our health and the health of an ecosystem, but also to our pocketbooks. Forest cover has been directly linked to drinking water treatment costs, so the more forest in a source water watershed, the lower the cost to treat that water. Forests provide these benefits by filtering sediments and other pollutants from the water in the soil before it reaches a water source, such as a stream, lake or river." | American Forests

Since this intake and outtake of water is gradual, removal of these forests can even to lead to a higher chance of both droughts and floods.

Have you heard of the beautiful living root bridges in Meghalaya, India? Their construction is a lesson in patience as the roots are gradually encouraged to grow in the supportive shape. They need regular care, but grow stronger with age.

>“Once a bamboo structure has been stretched across the river, the roots of the tree, usually the rubber tree (Ficus elastica), are teased and manipulated to become entwined with the bamboo until it becomes a strong mesh. > The roots are allowed to grow gradually and strengthen over time. In the initial stages, only about 15-20 people can cross the bridge in a day. Much later, it can be as many as 50 or more, although it can take up to two decades for a living roots bridge to be finished.” | The Guardian

Once done, the bridges can have a lifespan of several hundred years; far outliving the original creators of them.

It is unknown when this tradition started, but they were written about in 1844, so it would be far earlier than that.

I just thought people on here might find this tradition as fascinating as I do.

One summer evening, Bogdziewicz was sitting on his balcony reading a study which found that the timing of leaf senescence — the natural aging process leaves go through each autumn — depends on when the local weather warms relative to the summer solstice. Inspired by this finding, he sent the paper to his research group and called a brainstorming session. > > >It’s the first time that researchers have identified day length as a cue for masting. While Koenig cautioned that the result is only correlational, he added that “there’s very little out there speculating on how the trees are doing what they’re doing.” > > >If the solstice is shown to activate a genetic mechanism, it would be a major breakthrough for the field. Currently, there’s little data to explain how trees behave as they do. No one even knows whether trees naturally grow old and die, Vacchiano said. Ecologists struggle just to study trees: From branches to root systems, the parts of a tree say very little about the physiology of the tree as a whole. What experts do know is that discovering how trees sense their environment will help them answer the questions that have been stumping them for decades.

>Published in Nature, the study underscores the importance of global forests in absorbing carbon dioxide and calls for immediate action to protect these ecosystems.

>Key findings of the study > >Researchers examined long-term ground measurements combined with remote sensing data and found significant regional variations in the capacity of forests to act as carbon sinks:

>Boreal Forests: > >• Significant decline in carbon sink capacity by 36 percent. > >• Factors: increased disturbances from wildfires, insect outbreaks, and soil warming.

>Tropical Forests: > >• 31 percent decrease in carbon absorption capacity due to deforestation. > >• Regrowth in previously abandoned agricultural lands and logged areas partially offsets these losses.

>Temperate Forests: > >• 30 percent increase in carbon sink capacity. > >• Reasons: extensive reforestation efforts, particularly in China.

>Although deforestation rates in the Brazilian Amazon have halved, it is still losing more than 5,000km² every year. That’s an area three times larger than Greater London. > >By combining satellite imagery for the entire Amazon region with data from the Brazilian national census, our new study found that deforestation in areas protected by Indigenous communities was up to 83% lower compared to unprotected areas. These results show that Indigenous communities can play an important environmental stewardship role by helping to prevent deforestation by people encroaching on their lands.
