A violent storm ripped through the Amazon forest in 2005 and single-handedly killed half a billion trees, a new study reveals.The study is the first to produce an actual tree body count after an Amazon storm.
An estimated 441 million to 663 million trees were destroyed across the whole Amazon basin during the 2005 storm, a much greater number than previously suspected.
In some areas of the forest, up to 80 percent of the trees were killed by the storm. A severe drought was previously blamed for the region's tree loss in 2005.
"We can't attribute [the increased] mortality to just drought in certain parts of the basin — we have solid evidence that there was a strong storm that killed a lot of trees over a large part of the Amazon," said forest ecologist and study researcher Jeffrey Chambers of Tulane University in New Orleans, La.
From Jan. 16 to Jan. 18, 2005, a squall line — a long line of severe thunderstorms — 620 miles (1,000 kilometers) long and 124 miles (200 km) wide crossed the whole Amazon basin. The storm's strong winds, with speeds of up to 90 mph (145 kph), uprooted or snapped trees in half.
When trees die, they release their stored carbon into the atmosphere, which contributes to climate change. In a vicious cycle, these storms could become more frequent in the future due to climate change.
To calculate the number of trees killed by the storm, the researchers used satellite images, field studies and computer models. They looked for patches of wind-toppled trees, which allowed them to distinguish from trees killed by the drought.
"If a tree dies from a drought, it generally dies standing. It looks very different from trees that die snapped by a storm," Chambers said.
The storm wiped out between 300,000 and 500,000 trees in the area of Manaus, Brazil, alone. The number of trees killed by the 2005 storm was equal to 30 percent of the total human-caused deforestation in that same year for the Manaus region. The researchers used the tree loss in Manaus to estimate the tree loss across the entire Amazon basin.
"It's very important that when we collect data in the field we do forensics on tree mortality," Chambers said. "Under a changing climate, some forecasts say that storms will increase in intensity. If we start seeing increases in tree mortality, we need to be able to say what's killing the trees."
The study, funded by NASA and Tulane University, will be detailed in a future edition of the journal Geophysical Research Letters.

What I want to know is; since the storm took out as many trees as they cut, then does that mean they didn't have to cut down any trees for the following year.
Probably not when you consider clear cutting for farming, but I'm still curious as to how this effected the deforestation, by humans, on the rain forest.

Then I would hope that there would have been a similar decrease in the trees cut for timber within the same year.

I've ordered a lot of books from them, but even I don't think I can read enough books to kill that many trees. Perhaps I should just get a Kindle.

This same thing happened with Katrina an over looked occurrence that clearly shows mother nature is in charge and whether or not you agree with climate change we all should realize the weather is going to get a lot worse from here out.

Two weeks after Katrina I spent time in Louisana and MIssissippi. There were so many trees down ( yellow pines ) that the guy in the "yella wood" commercials would have been devistated. Wonder if he cries yella fella tears to hear the Amazon lost the trees.
On a serious note the Yellow Pines have really small root systems and fell over quite easily. - 2 years ago

"When trees die, they release their stored carbon into the atmosphere, which contributes to climate change. In a vicious cycle, these storms could become more frequent in the future due to climate change."

"The great rainforest of the Amazon basin is an important player in the global carbon cycle -- both a "sink" and a source of atmospheric carbon dioxide -- and is the subject of numerous studies related to our changing climate and a future of global warming. Earlier studies attributing all of the big 2005 die-off to drought were not based on field work that examined the cause of the death of individual trees.
Author of one such study, Professor Oliver Phillips at Leeds University in the UK, told Discovery News the new research describes "an interesting phenomenon, but its basinwide implications are unclear and I don't see any conflict with our work."
"We observed that across Amazonia the probability of tree death during 2005 increased in direct proportion to the rainfall deficit experienced locally," he said. Moreover, "we were able to also determine that forests which did not experience drought did not, on average, experience extra mortality."
Still, the new study introduces an intriguing, abrupt time element to the mix of causes and effects."

This one event of a huge storm may or may not be attributable in part to AGW, however, the effect of the tree deaths caused by it as was stated here may also contribute to the very climate change that then contributes to stronger storms. - 2 years ago

If watching hours and hours on end of National Geographic and Discovery Channel has taught me anything it's that trees dying in the Amazon is a good thing, because it opens a hole in the canopy for seedlings on the jungle floor to get sunlight and grow. It's something like a 10 to 1 ratio of trees that grow into the vacant canopy opening and the decaying dead trees provide the perfect decomposing nutrient rich stuff for fertilizer for them too. So this is actually a good thing. ...even though it was like Poland 1939 for 'those' trees.

I'm pretty sure just one volcano can pump a lot more CO2 into the atmosphere than all of these decomposing trees combined. And there's something like 500 erupting volcanoes on Earth at any one time.

a tree falling in the rain forest here or there is a good thing, but when that many trees die all at once, what tree is left to release seeds to start off the next generation

I hope you're right, but it probably wont be that simple. In recently heavily disturbed rain forests, fast growing vines and weeds can often invade before tree species have a chance to reestablish, means the vines and weeds take over the area rather than the rainforest regenerating. -- this is the bane off all rain forest restoration projects.

So let's see: we burn fossil fuels along with chopping down the Amazon to grow soy for animal feed along with all of the other destructive activities such as logging to make room for the cattle that eat the soy that then exacerbates the climate change that then brings on the stronger storms that then down more trees to free more CO2 to exacerbate it further as we keep on deforesting the land to grow more soy for cows to then eat them to perpetuate the cycle even more even though we know these actions will bring these effects. Wow, humans are stupid.
