Jair Bolsonaro can't hide tree crimes from these satellite eyes

Quaint cobblestone towns and green pastures dot the Pyrenees Mountains, at the gates of Catalonia’s Aigüestortes i Estany de Sant Maurici National Park. Hike a few miles into the park, though, and the Spanish landscape of trickling rivers and montane meadows looks relatively untouched by people. Visit almost any national park, and it’s a similar story, with tourist towns, farms, and other development lapping at the edges of conserved lands. But just how much does the landscape change at these fringes over time compared with the protected areas?

Lodgepole pines attacked by mountain pine beetles release volatile chemical compounds to warn related trees of the incoming threat, according to a new University of Alberta study. The study, published in Science of the Total Environment, is the first to establish above-ground tree-to-tree communication in pines by using chemical messages.

The letters came from everywhere—Verona, Italy; Littleton, Colorado; Oakland, California; Augsburg Germany; Sherrodsville, Ohio; Springfield, Massachusetts; Bronx, New York. They were written by children, teenagers, and adults, and while some were just a few words, others filled pages with detailed life stories. But they all shared the same sentiment: Please take back the rocks we stole. We’re sorry; we shouldn’t have done it.

The head of Brazil's National Institute for Space Research (INPE) has left his position following a public dispute with President Jair Bolsonaro over the agency's data, which showed an accelerated rate of deforestation in the Amazon. After meeting Marcos Pontes, Brazil's science and technology minister, on Friday, Ricardo Galvao said he would be leaving due to an "unsustainable" situation.

Only 30 per cent of the world’s primary forests are still intact. Deep in the interior of British Columbia, an ancient temperate rainforest that holds vast stores of carbon is being clear-cut as fast as the Amazon

Certain tree species not growing back in low elevation areas; seedlings struggling to survive in Rocky Mountains due to warming temperatures.

Deforestation is shooting up again in the Brazilian Amazon, according to satellite monitoring data. But Brazil’s far-right president, Jair Bolsonaro, whom many blame for the uptick, has disputed the trend and attacked the credibility of Brazil’s National Institute for Space Research (INPE), which produced the data. Bolsonaro called the numbers “a lie” during a 19 July breakfast talk with journalists, and suggested INPE Director Ricardo Galvão was “at the service of some [nongovernmental organization].”

Data confirms fears that Jair Bolsonaro’s policy encourages illegal logging in Brazil

“Each degree of warming causes way more fire than the previous degree of warming did. And that’s a really big deal.”

Global temperatures could rise 1.5° C above industrial levels by as early as 2030 if current trends continue, but trees could help stem this climate crisis. A new analysis finds that adding nearly 1 billion additional hectares of forest could remove two-thirds of the roughly 300 gigatons of carbon humans have added to the atmosphere since the 1800s.

Bark beetles do not cause damages in natural forests such as the Bavarian Forest National Park where they are part of the natural dynamic processes that occur in forests. It is the ideal environment for scientists to study the insects and their impact on forests and to draw conclusions for forestry operations.

The construction of logging roads in the region has doubled over the past 15 years, and researchers warn that this increase could have serious environmental ramifications.

In the face of more intense and frequent wildfires, federal land managers consider adopting burning practices the Southeast has been successfully using for decades. By Maya Miller, Samantha Max.

BRASILIA (REUTERS) - Deforestation of the Amazon rainforest in Brazil sped up in May (2019) to the fastest rate in a decade, according to data from an early-warning satellite system, as experts pointed to activity by illegal loggers encouraged by the easing of environmental protections under President Jair Bolsonaro..

Data from the blaze in Utah could improve models of how wildfire smoke spreads.

One of the main nurseries for an Ontario tree planting program that's being scrapped by the province said it will likely have to destroy about three million trees because of the cancellation.

Urban trees grow more quickly but die faster than rural trees, resulting in a net loss of street-tree carbon storage over time, according to a study published May 8 in the open-access journal PLOS ONE by Ian Smith of Boston University, US and colleagues. The findings suggest that planting initiatives alone may not be sufficient to maintain or enhance canopy cover and biomass due to the unique demographics of urban ecosystems.

As spring settles in across the United States, western states are already preparing for summer and wildfire season. And although it may seem counter-intuitive, some of the most urgent conversations are about getting more fire onto the landscape. Winter and spring, before conditions become too hot and dry, are common times for conducting planned and controlled burns designed to reduce wildfire hazard. Fire managers intentionally ignite fires within a predetermined area to burn brush, smaller trees and other plant matter.
