WOOD PILE
Forest fires contributed to record global tree cover loss
by Staff Writers
Washington (AFP) Oct 24, 2017


A sharp increase in forest fires stoked record losses in global forest cover equivalent to the area of New Zealand in 2016, a Global Forest Watch report said Monday.

The alarming pace of destruction -- 51 percent higher than the prior year with a loss of 73.4 million acres (29.7 million hectares), according to data from the University of Maryland -- was partially due to climate change that has increased the risks and intensity of wildfires by triggering temperature rise and drought in some places, the monitor said.

The 2015-2016 weather phenomenon El Nino, one of the strongest on record, also played a role, having created particularly dry conditions in the tropics.

Many of those tropical areas are not naturally prone to catching fire -- but vulnerability increased due to poor management and was exacerbated by El Nino.

Deadly blazes in Brazil and Indonesia were among those contributing to the loss. This year, deadly blazes have again devastated regions of Portugal as well as California.

Brazil's Amazon region lost 9.1 million acres of tree cover -- more than three times that of 2015.

And Portugal saw some four percent of its forests go up in smoke in 2016, the highest proportion of any other country.

Nearly half of all forests burned in the European Union in 2016 were in Portugal, where fire-prone eucalyptus and pine plantations along with poor soil encouraged the deadly flames.

The country is set to break the record for destroyed forests in 2017, with recent disasters killing dozens of people.

Early 2016 saw one of the largest fires ever recorded in Central Africa, destroying 37,000 acres of forest in the Republic of Congo.

Last year's Fort McMurray fire in Canada ravaged more than 1.5 million acres, causing $8.8 billion in damage.

Deforestation resulting from agriculture, logging and mining also contributed to the losses.

The report urged improving fire and forest management, including early warning systems, fire bans during dry seasons and more augmented investment in forest protection and restoration.

Tropical tree roots represent an underappreciated carbon pool
Panama City, Panama (SPX) Oct 18, 2017
Ask someone to draw a tree and s/he will invariably draw a trunk and branches - leaving the roots out of the picture. In a unique study of tropical tree roots at the Smithsonian Tropical Research Institute published in PLOS ONE, roots accounted for almost 30 percent of the total biomass of young trees. The authors hope that future estimates of carbon storage and water-use by tropical forests wil ... read more
