Treasure trove of unknown varieties of animal, bird, fish, insect and plant have been identified in the forests and wetlands of the Pacific island over a period of just 10 years
Tracy McVeigh The Observer The Guardian 26 Jun 11;
A new type of tree kangaroo, a 2.5-metre-long river shark, a frog with vampire-like fangs and a turquoise lizard are among hundreds of new creatures found and being documented in a report by conservationists working in the Pacific island of New Guinea.
Some 1,060 previously unknown species of mammals, fish and birds have been spotted in the volcanic island over a 10-year period.
The Final Frontier report, which was put together by WWF as part of its 50th anniversary celebrations, marks a brief respite from the escalating rate of animal and plant extinctions which is taking its toll across the planet and has left a quarter of all known mammals on the endangered list.
The species have all been discovered, at a rate of two each week, in the period from 1998 to 2008 by the various teams and researchers who have visited the region and its extensive forests, waters and wetlands.
One team discovered a new bird, the wattled smoky honeyeater, within seconds of leaving their expedition helicopter.
Perhaps the most extraordinary freshwater discovery is the species of river shark which, given its size, has done well to evade discovery until now. The shy fish has been named the Glyphis garricki after the New Zealand zoologist Jack Garrick, who identified it. Because of its rarity it has immediately gone on to the endangered list.
In the salt waters a snub-fin dolphin that comes in a delicate shade of pink was spotted in 2005 and, after much scientific measuring and debating, now qualifies as the first new dolphin species to be found in more than three decades.
Dr Mark Wright, conservation science adviser at WWF, said the report was a fabulous reminder that "the world is full of fantastic and fantastical creatures, of quirky and improbable lifestyles. The more we look, the more we find".
But he said that species diversity was rich the world over. "Perhaps it is so commonplace we ignore it, or maybe we've forgotten how to look. Let's take flies. Britain is home to more than 5,000 species of fly, and these are not everyone's favourite, but flies represent 5,000 entirely different responses to life's challenges.
"For instance, the holly leaf miner, whose nondescript larvae cause leaf blotching at this time of year – their entire world is limited to that tiny strip between the top and bottom of a single leaf. Those same life processes that we go through – feeding, growing, breathing – are still acted out, but now crammed into a creature far smaller than a grain of rice."
New Guinea is in an area known as the "coral triangle", a region with the most diverse marine eco-systems on Earth. In the 10-year period in question, 33 new fish species have been found in the waters around the island, including the damselfish, a strikingly brilliant blue wrasse and seven species of zig-zag rainbow fish, an 11cm-long creature which lives in shallow waters. In all, 218 new kinds of plants – including a flesh-like orchid, 43 reptiles and 12 mammals, 580 invertebrates, 134 amphibians, two birds and 71 fish have been found.
"It is precisely that endless variety of form and function that enthrals me, but this exuberance of nature is under threat," said Wright. "Despite the best efforts of groups like WWF, it is clear that we will not save all we would like to.
"Forest will continue to be felled, rivers dammed and coastlines developed. And species will be erased. Some extinction is inevitable – a consequence of Darwin's 'natural selection' – but humans are imposing intense pressures, leading to 'unnatural selection'. Nature is struggling to cope, but we have the ability and power in our hands to forge a future in which the environment is truly valued – we must choose to do so."
New Guinea is the second largest island on Earth, after Greenland, and is divided between the countries of Papua New Guinea and Indonesia. It holds the third largest tract of rainforest in the world and is home to around 8% of the world's species.
But while its relatively low level of human population had protected its species, illegal logging is now projected to strip the island of half of its forest cover by 2020.
To support WWF's anniversary report, writer and film-maker Stephen Poliakoff has made a short film which will include footage of some of the new species from New Guinea. Called Astonish Me, the film will be shown exclusively online by the Observer later this summer before being shown in Odeon cinemas as a short feature prelude to major films.
Poliakoff said that his drama – which stars Bill Nighy – had been inspired by the new discoveries made in the natural world.
"What astonishes me is there are so many animals out there we are seeing for the first time from the very colossal squid to the largest insect in the world discovered recently – it's extraordinary in the 21st century that this is still going on. We think we know everything, but we don't," he said.
More than 1000 new species found in New Guinea
WWF 27 Jun 11;
Port Moresby, Papua New Guinea - A remarkable 1,060 new species have been discovered the island of New Guinea from 1998 to 2008, but poorly planned and unsustainable development - particularly from logging and forest conversion to agriculture - is putting many of these unique creatures at risk, a new WWF study finds.
Final Frontier: Newly Discovered species of New Guinea (1998 – 2008) shows that 218 new kinds of plants - close to 100 of which are orchids - 43 reptiles and 12 mammals, including a unique snub-fin dolphin, have been found on the tropical island over a ten year period.
Added to the tally is an astounding 580 invertebrates and 134 amphibians, 2 birds and 71 fish, among them an extremely rare 2.5m long river shark.
“This report shows that New Guinea’s forests and rivers are among the richest and most biodiverse in the world. But it also shows us that unchecked human demand can push even the wealthiest environments to bankruptcy,” says Dr. Neil Stronach, WWF Western Melanesia’s Program Representative.
Untouched rainforest
New Guinea is the largest tropical island on Earth and is divided between the countries of Papua New Guinea (PNG) in the East and Indonesia in the West. It contains the third largest tract of rainforest in the world after the Amazon and the Congo.
This mysterious island covers less than 0.5 per cent of the Earth’s landmass but shelters 6 to 8 per cent of the world’s species. Over two thirds of these species are found nowhere else on earth.
It is also home to Asia’s most pristine rivers and wetlands. Its natural gifts also extend to the reefs surrounding New Guinea, in the heart of the Coral Triangle, which have the world’s highest concentration of coral and reef fish.
“If you look at New Guinea in terms of biological diversity, it is much more like a continent than an island,” says Dr. Stronach. “Scientists found an average of two new species each week from 1998 – 2008 – nearly unheard of in this day and age,” he says.
No fewer than seven brightly colored new species of rainbow fish were identified in PNG and Papua in Indonesia over the ten-year period, including Allen’s rainbow fish (Chilatherina alleni).
WWF scientists added to the known orchid diversity found on the island, collecting hundreds of orchids in PNG’s Kikori region. Eight of these were new to science, including the ornate and exquisite firework-like display of the Dendrobium spectabile orchid.
Alarming rate of forest loss
“Despite its remote location, New Guinea’s natural habitats are being lost at an alarming rate. The island’s forests are facing serious threats including logging, mining, wildlife trade and conversion to agriculture, particularly oil palm,” says Dr. Eric Verheij, Conservation Director, WWF Western Melanesia.
In PNG between 1972 and 2002, independent studies have shown that 24 per cent of rainforests were cleared or degraded through logging or subsistence agriculture.
The same studies point out that the forest clearance rate for forests accessible to industrial logging is up to 3.4 per cent annually, much higher than previously reported.
China buys close to 82 per cent of PNG’s timber exports each year, representing a total volume of over two million cubic meters. Studies suggest 70 per cent of this logging is illegal.
Demand for palm oil is also destroying many of New Guinea’s most valuable rainforests. Large forest areas on the island (and across the region) are being cleared for oil palm monocultures, destroying critical habitat for many endangered species. The destruction of these forests, which are usually cleared by burning releases huge amounts of greenhouse gasses into the atmosphere and accelerates climate change.
However, many oil palm producers in New Guinea and around the world are pursing certification through the Roundtable on Sustainable Palm Oil (RSPO), the world’s most credible sustainable palm oil initiative. Certified Sustainable Palm Oil (CSPO) guarantees that social and environmental safeguards have been met during production. And importantly, CSPO also assures that high conservation value forests haven’t been cleared.
Based on the first chapter of WWF’s new Living Forests Report, more than 230 million hectares of forest will disappear around the world by 2050 if no action is taken. The report proposes that policymakers and businesses unite around a goal of Zero Nett Deforestation and Degradation (ZNDD) by 2020 as a global benchmark to avoid dangerous climate change and curb biodiversity loss.
“As a region with high rates of poverty, it is absolutely essential that New Guinea’s precious reefs, rainforests, and wetlands are not plundered but managed sustainably for future generations,” says Dr Susanne Schmitt, New Guinea Programme Manager at WWF-UK.
“Environmental protection and economic development must go together to ensure the survival of New Guinea’s unique species and natural habitats,” added Dr. Schmitt.
