Tropical Storm Isaac drenches Haiti, aims for Cuba

PORT-AU-PRINCE (Reuters) - Tropical Storm Isaac emerged over warm Caribbean waters on Saturday slightly weaker but ready to regroup after dumping torrential rains on Haiti, where thousands of people remain homeless more than two years after a devastating earthquake.

Heavy rains and high winds lashed Haiti's southern coast, flooding parts of the capital Port-au-Prince, and flattening tents in some of the fragile resettlement camps that house more than 350,000 survivors of the 2010 earthquake.

A 10-year-old girl was killed in Port-au-Prince when a wall fell on her, the Civil Protection authority said. Power outages and flooding were reported as Isaac moved across the hilly and severely deforested Caribbean country.

"There's a lot of rain, a lot of wind," said Magdala Jean-Baptiste, who huddled with her frightened children in their home in the southern coastal city of Jacmel. "We haven't had any power since the storm started yesterday. We passed the night with no sleep."

Isaac was forecast to sweep over eastern Cuba on Saturday and strengthen into a hurricane as it approaches the Florida Keys. It was on track for the Gulf of Mexico, where major energy companies have begun offshore evacuations that could end up shutting nearly half the area's oil output.

The center of Isaac was about 95 miles east-southeast of Guantanamo Bay, Cuba, on Saturday morning, the U.S. National Hurricane Center said.

A hurricane warning was in effect for the Florida Keys and the southwest coast of Florida.

Isaac's march across the Caribbean comes as U.S. Republicans prepare to gather in Tampa, on Florida's central Gulf Coast, for Monday's start of their national convention ahead of the November presidential election. The convention is expected to proceed as planned.

In the Dominican Republic, Isaac felled power and phone lines and left at least a dozen towns cut off by flood waters. The most severe damage was reported along the south coast, including the capital Santo Domingo, where more than half the city was without power.

In Haiti, the United Nations mission there said it was prepared to distribute food and emergency supplies for more than 300,000 people, and 5,700 U.N. troops stood ready to clear roads for emergency response teams.

The government and aid groups tried to evacuate thousands of tent camp dwellers on Friday but many Haitians chose to remain in their flimsy, makeshift homes, apparently fearing they would be robbed, said Bradley Mellicker, head of disaster management for the International Organization for Migration (IOM).

REFUGE FROM THE STORM

Volunteers from the government's Civil Protection office were sent across Haiti, warning people about flood and landslide risks. About 1,250 shelters opened in schools, churches and other buildings but Red Cross officials said the number could be grossly inadequate. Prime Minister Laurent Lamothe acknowledged Haiti had "limited means" to ensure public safety.

Red Cross and IOM representatives joined government officials in trying to evacuate 8,000 of the "most vulnerable people," including 2,500 sick and disabled, from 18 tent camps in low-lying coastal areas of Port-au-Prince.

Many Haitians, most of whom scrape by on less than $1 per day, consider disaster an inevitable part of life in the poorest country in the Americas.

"We live under tents. If there's too much rain and wind, water comes in. There's nothing we can do," said Nicholas Absolouis, an unemployed 34-year-old mechanic at one camp for homeless people on the northern edge of the chaotic capital.

Flooding could also help reignite a cholera epidemic, which has killed more than 7,500 people in Haiti since the disease first appeared in October 2010, foreign aid workers said.

After crossing Cuba and the Florida Keys, Isaac was forecast to move north to northwest through the Gulf of Mexico and make landfall anywhere on the U.S. coast from the Florida Panhandle to New Orleans at midweek.

Emergency managers urged tourists to leave the Keys if they could do so safely on Saturday. A single road links the chain of low-lying islands to the Florida Peninsula.

Officials said Key West International Airport will stop commercial air traffic on Saturday evening and all day Sunday.

Isaac has drawn especially close scrutiny because of the Republican Party's convention, a four-day meeting during which former Massachusetts Governor Mitt Romney will receive the party's presidential nomination.

Party officials insist the convention will go ahead, even if they have to alter the schedule. But NHC meteorologist Rick Danielson said late on Friday that Tampa could be hit by coastal flooding and driving winds or rain.

"There is still a full range of possible impacts on Tampa at this point," he said.

Airborne technology helps manage elephants

ScienceDaily (Aug. 6, 2012) ? For years, scientists have debated how big a role elephants play in toppling trees in South African savannas. Tree loss is a natural process, but it is increasing in some regions, with cascading effects on the habitat for many other species. Using high resolution 3-D mapping, Carnegie scientists have for the first time quantitatively determined tree losses across savannas of Kruger National Park. They found that elephants are the primary agents -- their browsing habits knock trees over at a rate averaging 6 times higher than in areas inaccessible to them.

The research also found that elephants prefer toppling trees in the 16-to-30 foot (5-8 m) range, with annual losses of up to 20% in these height classes. The findings, published in Ecology Letters, bolster our understanding of elephant conservation needs and their impacts, and the results could help to improve savanna management practices.

"Previous field studies gave us important clues that elephants are a key driver of tree losses, but our airborne 3-D mapping approach was the only way to fully understand the impacts of elephants across a wide range of environmental conditions found in savannas," commented lead author Greg Asner of Carnegie's Department of Global Ecology. "Our maps show that elephants clearly toppled medium-sized trees, creating an "elephant trap" for the vegetation. These elephant-driven tree losses have a ripple effect across the ecosystem, including how much carbon is sequestered from the atmosphere."

The technology used for monitoring trees is Light Detection and Ranging (LiDAR), mounted on the fixed-wing Carnegie Airborne Observatory (CAO). It provides detailed 3-D images of the vegetation canopy at tree-level resolution using laser pulses that sweep across the African savanna. The CAO's lasers can detect even small changes in each tree's height, and its vast coverage is far superior to previous field-based and aerial photographic evaluations. The scientists considered an array of environmental variables spread over four study landscapes within Kruger and in very large areas fenced off to prevent herbivore entry. For years, four of these exclosures have kept out all herbivores larger than a rabbit. Two other partial enclosures have permitted entry of herbivores other than elephants.

The scientists identified and monitored 58,000 individual trees from the air, inside and outside of these exclosures and across the landscape in 2008 and again in 2010. They found that nearly 9% of the trees decreased in height in two years, and that the mapped changes in treefall were linked to different climate and terrain conditions. Most tree losses occurred in lowland areas with more moisture and on soils high in nutrients that harbor trees preferred by elephants for browsing. Critically, the partial exclosures definitively identified elephants, as opposed to other herbivores and fire, as the major agent of tree losses over the two-year period.

"These spatially explicit patterns of treefall highlight the challenges faced by conservation area managers in Africa, who must know where and how their decisions impact ecosystem health and biodiversity. They should rely on rigorous science to evaluate alternative scenarios and management options, and the CAO helps provide the necessary quantification," commented co-author Shaun Levick.

Danie Pienaar, head of scientific services of the South African National Parks remarked, "This collaboration between external scientists and conservation managers has led to exciting and ground-breaking new insights to long-standing questions and challenges. Knowing where increasing elephant impacts occur in sensitive landscapes allows park managers to take appropriate and focused action. These questions have been difficult to assess with conventional ground-based field approaches over large scales such as those in Kruger National Park."
