151 new dam projects in Amazon basin pose dire threat to rainforest ecology

By Rhett A. Butler / Mongabay

More than 150 new dams planned across the Amazon basin could significantly disrupt the ecological connectivity of the Amazon River to the Andes with substantial impacts for fish populations, nutrient cycling, and the health of Earth’s largest rainforest, warns a comprehensive study published in the journal PLoS ONE.

Scouring public data and submitting information requests to governments, researchers Matt Finer of Save America’s Forests and Clinton Jenkins of North Carolina State University documented plans for new dams in Bolivia, Brazil, Colombia, Ecuador, and Peru. They found that 40 percent of the projects are already in advanced planning stages and more than half would be large dams over 100 megawatts. 60 percent of the dams “would cause the first major break in connectivity between protected Andean headwaters and the lowland Amazon”, while more than 80 percent “would drive deforestation due to new roads, transmission lines, or inundation.”

“These results are quite troubling given the critical link between the Andes Mountains and the Amazonian floodplain,” said lead author Finer in a statement. “There appears to be no strategic planning regarding possible consequences to the disruption of an ecological connection that has existed for millions of years.”

Finer and Jenkins note that the Andes are a critical source of sediments, nutrients, and organic matter for the Amazon river, feeding the floodplain that supports the rich Amazon rainforest. The Amazon and it tributaries are critical highways for migratory fish that move to headwaters areas to spawn.”Many economically and ecologically important Amazonian fish species spawn only in Andean-fed rivers, including a number that migrate from the lowlands to the foothills,” the authors write. “The Andean Amazon is also home to some of the most species rich forests and rivers on Earth. The region is documented to contain extraordinary richness for the most well studied taxa… and high levels of endemism for the understudied fishes. Therefore, any dam-driven forest loss or river impacts are of critical concern.”Finer and Jenkins conducted a meta-analysis of river connectivity and infrastructure to produce an “ecological impact score” for all 151 dams. 47 percent of the dams were classified as “high impact” while only 19 percent were rated “low impact”. Eleven of the dams would directly affect a conservation area.

The hydroelectric projects would also have social impacts. Forty dams would be constructed “immediately upstream or downstream” on an indigenous territory.Worryingly the authors conclude that there is seemingly no basin-wide policy assessment of the potential social and ecological impacts of the dam-building spree.“We conclude that there is an urgent need for strategic basin scale evaluation of new dams and a plan to maintain Andes-Amazon connectivity,” said study co-author Jenkins in a statement. “We also call for a reconsideration of the notion that hydropower is a widespread low impact energy source in the Neotropics.”  Finer and Jenkins warn that the perception dams in tropical forest areas are a clean energy source could lead to perverse subsidies for the projects via the carbon market.

BP oil spill pollution producing mutated fish, shrimp without eyes, and crabs with soft shells

By Dahr Jamail / Al Jazeera

“The fishermen have never seen anything like this,” Dr Jim Cowan told Al Jazeera. “And in my 20 years working on red snapper, looking at somewhere between 20 and 30,000 fish, I’ve never seen anything like this either.”

Dr Cowan, with Louisiana State University’s Department of Oceanography and Coastal Sciences started hearing about fish with sores and lesions from fishermen in November 2010.

Cowan’s findings replicate those of others living along vast areas of the Gulf Coast that have been impacted by BP’s oil and dispersants.

Gulf of Mexico fishermen, scientists and seafood processors have told Al Jazeera they are finding disturbing numbers of mutated shrimp, crab and fish that they believe are deformed by chemicals released during BP’s 2010 oil disaster.

Along with collapsing fisheries, signs of malignant impact on the regional ecosystem are ominous: horribly mutated shrimp, fish with oozing sores, underdeveloped blue crabs lacking claws, eyeless crabs and shrimp – and interviewees’ fingers point towards BP’s oil pollution disaster as being the cause.

Eyeless shrimp

Tracy Kuhns and her husband Mike Roberts, commercial fishers from Barataria, Louisiana, are finding eyeless shrimp.

“At the height of the last white shrimp season, in September, one of our friends caught 400 pounds of these,” Kuhns told Al Jazeera while showing a sample of the eyeless shrimp.

According to Kuhns, at least 50 per cent of the shrimp caught in that period in Barataria Bay, a popular shrimping area that was heavily impacted by BP’s oil and dispersants, were eyeless. Kuhns added: “Disturbingly, not only do the shrimp lack eyes, they even lack eye sockets.”

“Some shrimpers are catching these out in the open Gulf [of Mexico],” she added, “They are also catching them in Alabama and Mississippi. We are also finding eyeless crabs, crabs with their shells soft instead of hard, full grown crabs that are one-fifth their normal size, clawless crabs, and crabs with shells that don’t have their usual spikes … they look like they’ve been burned off by chemicals.”

On April 20, 2010, BP’s Deepwater Horizon oilrig exploded, and began the release of at least 4.9 million barrels of oil. BP then used at least 1.9 million gallons of toxic Corexit dispersants to sink the oil.

Keath Ladner, a third generation seafood processor in Hancock County, Mississippi, is also disturbed by what he is seeing.

“I’ve seen the brown shrimp catch drop by two-thirds, and so far the white shrimp have been wiped out,” Ladner told Al Jazeera. “The shrimp are immune compromised. We are finding shrimp with tumors on their heads, and are seeing this everyday.”

While on a shrimp boat in Mobile Bay with Sidney Schwartz, the fourth-generation fisherman said that he had seen shrimp with defects on their gills, and “their shells missing around their gills and head”.

“We’ve fished here all our lives and have never seen anything like this,” he added.

Ladner has also seen crates of blue crabs, all of which were lacking at least one of their claws.

Darla Rooks, a lifelong fisherperson from Port Sulfur, Louisiana, told Al Jazeera she is finding crabs “with holes in their shells, shells with all the points burned off so all the spikes on their shells and claws are gone, misshapen shells, and crabs that are dying from within … they are still alive, but you open them up and they smell like they’ve been dead for a week”.

Rooks is also finding eyeless shrimp, shrimp with abnormal growths, female shrimp with their babies still attached to them, and shrimp with oiled gills.

“We also seeing eyeless fish, and fish lacking even eye-sockets, and fish with lesions, fish without covers over their gills, and others with large pink masses hanging off their eyes and gills.”

Rooks, who grew up fishing with her parents, said she had never seen such things in these waters, and her seafood catch last year was “ten per cent what it normally is”.

“I’ve never seen this,” he said, a statement Al Jazeera heard from every scientist, fisherman, and seafood processor we spoke with about the seafood deformities.

Given that the Gulf of Mexico provides more than 40 per cent of all the seafood caught in the continental US, this phenomenon does not bode well for the region, or the country.

BP’s chemicals?

“The dispersants used in BP’s draconian experiment contain solvents, such as petroleum distillates and 2-butoxyethanol. Solvents dissolve oil, grease, and rubber,” Dr Riki Ott, a toxicologist, marine biologist and Exxon Valdez survivor told Al Jazeera. “It should be no surprise that solvents are also notoriously toxic to people, something the medical community has long known”.

The dispersants are known to be mutagenic, a disturbing fact that could be evidenced in the seafood deformities. Shrimp, for example, have a life-cycle short enough that two to three generations have existed since BP’s disaster began, giving the chemicals time to enter the genome.

Pathways of exposure to the dispersants are inhalation, ingestion, skin, and eye contact. Health impacts can include headaches, vomiting, diarrhea, abdominal pains, chest pains, respiratory system damage, skin sensitisation, hypertension, central nervous system depression, neurotoxic effects, cardiac arrhythmia and cardiovascular damage. They are also teratogenic – able to disturb the growth and development of an embryo or fetus – and carcinogenic.

Cowan believes chemicals named polycyclic aromatic hydrocarbons (PAHs), released from BP’s submerged oil, are likely to blame for what he is finding, due to the fact that the fish with lesions he is finding are from “a wide spatial distribution that is spatially coordinated with oil from the Deepwater Horizon, both surface oil and subsurface oil. A lot of the oil that impacted Louisiana was also in subsurface plumes, and we think there is a lot of it remaining on the seafloor”.

Marine scientist Samantha Joye of the University of Georgia published results of her submarine dives around the source area of BP’s oil disaster in the Nature Geoscience journal.

Her evidence showed massive swathes of oil covering the seafloor, including photos of oil-covered bottom dwelling sea creatures.

While showing slides at an American Association for the Advancement of Science annual conference in Washington, Joye said: “This is Macondo oil on the bottom. These are dead organisms because of oil being deposited on their heads.”

Dr Wilma Subra, a chemist and Macarthur Fellow, has conducted tests on seafood and sediment samples along the Gulf for chemicals present in BP’s crude oil and toxic dispersants.

“Tests have shown significant levels of oil pollution in oysters and crabs along the Louisiana coastline,” Subra told Al Jazeera. “We have also found high levels of hydrocarbons in the soil and vegetation.”

According to the US Environmental Protection Agency, PAHs “are a group of semi-volatile organic compounds that are present in crude oil that has spent time in the ocean and eventually reaches shore, and can be formed when oil is burned”.

“The fish are being exposed to PAHs, and I was able to find several references that list the same symptoms in fish after the Exxon Valdez spill, as well as other lab experiments,” explained Cowan. “There was also a paper published by some LSU scientists that PAH exposure has effects on the genome.”

The University of South Florida released the results of a survey whose findings corresponded with Cowan’s: a two to five per cent infection rate in the same oil impact areas, and not just with red snapper, but with more than 20 species of fish with lesions. In many locations, 20 per cent of the fish had lesions, and later sampling expeditions found areas where, alarmingly, 50 per cent of the fish had them.

“I asked a NOAA [National Oceanic and Atmospheric Administration] sampler what percentage of fish they find with sores prior to 2010, and it’s one tenth of one percent,” Cowan said. “Which is what we found prior to 2010 as well. But nothing like we’ve seen with these secondary infections and at this high of rate since the spill.”

“What we think is that it’s attributable to chronic exposure to PAHs released in the process of weathering of oil on the seafloor,” Cowan said. “There’s no other thing we can use to explain this phenomenon. We’ve never seen anything like this before.”

Climate change promoting beetle reproduction, with devastating effects on tree populations

By Sindya N. Bhanoo / The New York Times

Mountain pine beetles attack and kill weak pine trees, boring into bark to lay their eggs. They attack the trees in hordes, and their larvae feed off fungi in the trees.

Now, the beetles are reproducing twice a year instead of once, and millions of trees are dying as a result.

The beetle species is several million years old, and historically larvae grow to be adults in July or August every year. But it has been getting warmer earlier in the year, and larvae mature faster and emerge as early as May. These new beetles then immediately lay eggs, and a second generation of adult beetles emerges as early as July because summers are so warm, said Scott M. Ferrenberg, an evolutionary biologist at the University of Colorado at Boulder and an author of a study in the coming issue of The American Naturalist.

The researchers did their work at Niwot Ridge in Boulder County, at an elevation of 10,000 feet. Several decades ago, pine beetles were not found at that elevation, Mr. Ferrenberg said. “The invasion of that habitat above 9,000 feet has happened after several decades of significant warming,” he said.

He called the beetle phenomenon an epidemic, not limited to mountain pine beetles. Other trees are also under stress from other species of beetles.

“Spruce beetles and Douglas fir beetles are at epidemic levels,” he said. And southern pine beetles, typically found in the American South, are moving north.

“People are finding outbreaks in New Jersey,” Mr. Ferrenberg added.

Logging company in PNG hires police to lock indigenous landowners in shipping containers

By Jeremy Hance / Mongabay

Locals protesting the destruction of their forest in Papua New Guinea for two palm oil plantations say police have been sent in for a second time to crack-down on their activities, even as a Commission of Inquiry (COI) investigates the legality of the concession. Traditional landowners in Pomio District on the island East New Britain say police bankrolled by Malaysian logging giant Rimbunan Hijau (RH) have terrorized the population, including locking people in shipping containers for three consecutive nights. The palm oil concessions belongs to a company known as Gilford Limited, which locals say is a front group for RH.

“The current situation is very bad. The [villagers] are trying their best to do (a) blockade, but because of the police involvement the people are very scared to stand up and defend their land and speak their rights. The logging operation is still going on and is destroying the big forest, the rivers, and sea more every day,” a local landowner told mongabay. The landowner spoke on anonymity for fear of reprisal.

Last year, complaints over mistreatment by police in logging areas rose to such a feverish pitch across Papua New Guinea that police commissioner, Tom Kulunga, withdrew all police forces from logging areas in the country. But now locals in Pomio, at least, say the police have returned and abusive practices continue.

“The police have mistreated the locals by abusing them with sticks, fan belts, telling them to sit in the sun for five hours, swearing at them, arriving in the villages at nigh forcing them to sign papers with the people understanding the content, tying their hands to their back, and commanding them to run in the hot sun,” the landowner said, noting that the alleged abuse began on March 5th.

The landowner also said that the police locked up six people in shipping containers for three nights.

Last year, locals said the police were paid and flown in by Rimbunan Hijau (RH), which was confirmed by Assistant Police Commissioner Anton Billy to the Australian Broadcast Corporation (ABC) in an interview. He told the ABC that this was “normal.”

“We don’t have any funds to get these people there and pay them allowance and all this stuff,” Billy said.

The two palm oil concessions in question, covering some 26,000 hectares for a 99-year lease, are a part of a hugely controversial land program by the Papua New Guinea government known as Special Agricultural and Business Leases (SABLs). Critics contend SABLs are being used en masse to circumvent Papua New Guinea’s strong community land laws—where 97 percent of the land is ostensibly owned by local communities—granting massive areas of land to foreign corporations for extractive activities such as logging. SABLs have led to conflict and deforestation across Papua New Guinea. Last year the government suspended any new SABLs and launched an independent investigation into the practice, which up to then had handed over 5.2 million hectares to foreign corporations, an area larger than Costa Rica.

56 coral species may go extinct this century due to climate change and ocean acidification

By ENews Park Forest

Without help, more than 50 coral species in U.S. waters are likely to go extinct by the end the century, primarily because of ocean warming, disease and ocean acidification, a government report said today. The National Marine Fisheries Service released a status review of 82 corals that are being considered for protections under the Endangered Species Act following a 2009 petition by the Center for Biological Diversity.

“Coral reefs are at real risk of vanishing in our lifetimes if we don’t act fast,” said Miyoko Sakashita, oceans director with the Center for Biological Diversity. “The Endangered Species Act has saved hundreds of species from extinction, but these corals will only benefit if they’re actually protected.”

Of the 82 corals, 56 are likely to be extinct before 2100, the report said. The corals are in U.S. waters, ranging from Florida and Hawaii to U.S. territories in the Caribbean and Pacific. The report notes that the seven Florida and Caribbean corals are extremely likely to go extinct, and five of those corals ranked in the top seven of most imperiled overall. Today’s report makes no recommendation about whether the corals may warrant protection under the Endangered Species Act.

According to the status review, “The combined direct and indirect effects of rising temperature, including increased incidence of disease and ocean acidification, both resulting primarily from anthropogenic increases in atmospheric CO2, are likely to represent the greatest risks of extinction to all or most of the candidate coral species over the next century.”

Coral reefs are home to 25 percent of marine life and play a vital function in ocean ecosystems. Already one-third of the world’s coral reefs have been destroyed, and scientists warn that by mid-century most corals will be in inhospitable waters that are too warm or acidic. Since the 1990s, coral growth has grown sluggish in some areas due to ocean acidification, and mass bleaching events are increasingly frequent.
“I’m eager to show my kids the wonder of a coral reef. I worry that if we wait too long, they’ll never get to experience a healthy reef teeming with colorful life,” said Sakashita. “These delicate corals need help, first with federal protections, and then with dramatic reductions in carbon dioxide pollution.”

The Fisheries Service is accepting comments on the coral status review and management reports until July 31, 2012. Pursuant to a settlement agreement with the Center, the Fisheries Service will make a determination on whether listing is warranted for the corals by Dec. 1, 2012. In 2006, the Center secured protection for staghorn and elkhorn corals, making them the first — and so far, only — corals listed under the Endangered Species Act.

Evaluation Finds Pesticides Are Threatening Endangered Salmon

Evaluation Finds Pesticides Are Threatening Endangered Salmon

By Jill Ettinger / Organic Authority

West Coast salmon, an already threatened species, are the victim of a new, potentially detrimental threat according to a recent evaluation conducted by the National Oceanic and Atmospheric Administration’s Fisheries Service.

NOAA’s Fisheries Services identified the culprits as three pesticides commonly used in more than 100 pesticide products for home and agricultural applications including the treatment of soy, cotton, corn, grapes and Christmas trees: triflurali, oryzalin and pendimenthalin.

The request for restrictions on the pesticides was submitted as a result of legal action taken by conservation groups and salmon fishers concerned for the health and survival of the species.

According to the NOAA Fisheries report submitted to the EPA, the contamination from the pesticides may be jeopardizing as much as half of the 26 protected West Coast salmon populations already facing survival issues that make them protected by the Endangered Species Act.

In its submission to the EPA, NOAA requested the agency enforce restrictions including no-spray areas that would buffer the fish and help to keep the pesticide run-off from entering streams.

The three most common West Coast salmon species are chinook, coho and sockeye. More than 135 species depend on salmon, according to Salmon Nation. After returning to the place of their birth for spawning, salmon die, leaving their bodies as food for future generations. But the pesticides are creating new challenges for the species, making wild salmon an unsustainable catch for fishers who depend on the species, too. Trifluralin deforms the backbones of the fish, oryzalin poisons plants in the salmon’s environment as does pendimenthalin, which also poisons the food salmon eat.

“Those of us who fight to protect and restore rivers and their critical fisheries are very pleased that the biological opinions were released,” said Sharon Selvaggio, of Northwest Center for Alternatives to Pesticides. “To protect salmon, we need to respond to what the science is showing us.”
