New species, extinction lurk in Peru

2010-12-28 12:34
Lima - Each year, a new bird is found and every four years a new mammal discovered in the Peruvian Amazon, a haven for biodiversity where conservation and danger often go hand in hand.

Although Peru is known for its Andes mountain range, the Amazon actually covers 60% of the country's territory. It is a hotbed of bio-activity and is home to 25 000 species of plants - 10% of the world's stock.

Thanks to the Amazon, Peru has the world's second-largest bird population (1 800 species) and is among the top five countries for mammals (515 species) and reptiles (418 species).

This year alone, scientists stumbled upon a previously unknown leech and a new type of mosquito.

The animal population has grown in recent years, namely adding a mini poison dart frog with a fire-red head and blue legs (Ranitomeya amazonica), a purple-throated Sunangel hummingbird (Heliangelus viola) and a "tyrannosaurus leech" with eight teeth (Tyrannobdella reina).

Resource extraction

More than 1 200 new species of plants or animals have been discovered in 10 years in the Amazon, according to the Worldwide Fund for Nature. But paradoxically, the novel species are often discovered during the very activities that threaten the Amazon the most.

"Most of these discoveries don't happen during scientific expeditions, which are often costly. They most often come when workers are digging exploration sites for oil, mining or lumber companies," said WWF Peru's Amazon programme director Michael Valqui.

"This type of discovery is also simultaneously endangering the species that is being discovered in its one and only habitat."

Peru, home to one of the biggest forest lands - 700 000km2 - is also a magnet for resource extraction.

The number of concessions granted has doubled since 2006 to cover 16% of the territory, according to the Observatory of Mining Conflicts in Latin America.

At the same time, Peru boasts of being on the cutting edge of conservation, with 15% of its territory under protected status.

"And we're aiming for 30%," said Environment Minister Antonio Brack.

Biodiversity

Environmentalists, though, worry about the future of biodiversity and the species living outside these protected zones.

"There are no clear signals as to what the country intends to do to protect biodiversity," said Ivan Lanegra, representative of the influential government-funded Peruvian ombudsman office.

Gerard Herail of France's IRD research and development institute in Lima noted that "a mining or hydrocarbons firm is not innately destructive. The key is whether or not it is 'clean'," or uses cleaner methods and technologies.

More species are disappearing than are being discovered around the world, noted Ernesto Raez, who heads the Sustainable Development Centre at Cayetano Heredia University in Lima.

"In other words, species are disappearing before we discover them," he added.

But the IRD says the very context of their disappearance allows the group to "develop biodiversity conservation strategies", such as those deployed successfully for the huge arapaima or paiche fish (Arapaima gigas), one of the largest freshwater fish in the world.

Extinction

Twenty-one species remain in "critical danger" of extinction in Peru, according to 2004 numbers, including the short-tailed chinchilla (Chinchilla brevicaudata) and the sharp-eared bat (Tompoeas ravus). The leaf-eared mouse (phyllotis andinum) is believed to have already disappeared.

The Lima gecko (Phyllodactylus sentosus), a minuscule nocturnal lizard also in critical danger, illustrates the sometimes complex relationship between threat and conservation.

The gecko finds its habitat in the darkest corners of the huacas, pre-Hispanic burial grounds or ritual sites that dot Lima and the coast.

"But archaeologists' maintenance work, crucial for conservation, is exactly what's destroying the gecko's habitat" and triggering its downfall, said Valqui.
