A plan to release orangutans in a 250,000-hectare (618,000-acre) tract of forest in the Heart of Borneo has been disrupted by uncertainty around BHP Billiton's decision to pull out of a coal mining project in Kalimantan, the Indonesian part of Borneo, reports the Independent and conservation groups familiar with the situation.

BHP Billiton had provided funds to help establish the forest reserve in Central Kalimantan and offered conservationists mapping support and use of helicopters to deposit orangutans into otherwise inaccessible areas. The two-year program would have reintroduced scores of orangutans but the first scheduled airlift of 48 orangutans for July 20 was canceled after BHP warned it could no longer guarantee the safety of reintroduced orangutans. Last month BHP said it would pull out of the area for unspecified "strategic reasons", leaving the fate of its concessions in the hands of the Indonesian government. BHP fears that the concessions could go to companies that would take fewer environmental precautions, thereby imperiling the orangutans.

"BHP said it can't be part of a release if it can't be sure the orangutans will be safe," said a source who requested anonymity. The source noted that BHP may reinstate the airlift once it gets assurances that the orangutans will not be immediately at risk.

A working group has been created to help address the concerns. The group hopes to encourage new regulations in the Heart of Borneo whereby mining concessions handed back to the central government would be removed from the mining registry and made available for sustainable uses that benefit or protect biodiversity. The BHP concession area serves as the most important watershed in all of Borneo, feeding three major river systems, as well as providing a potential refuge for endangered orangutans.

In recent years, expansion of oil palm plantations across Borneo and Sumatra has replaced logging and the wildlife trade as the biggest threat to remaining populations. Rehabilitation facilities rescue orangutans as they are displaced by development in hopes of eventually reintroducing them into the wild. But conservationists report difficulty in locating secure sites for reintroduction.

The Heart of Borneo initiative may help. The initiative, which has some support from Malaysia, Indonesia and Brunei, the governments that share Borneo, aims to protect 220,000 square kilometers of ecosystems across central Borneo, including key orangutan habitat. Still the plan faces strong opposition from development interests, including mining, logging, and plantation companies.

Precedent for BHP's warming

BHP Billiton's warning for the well-being of wildlife after it pulls out of its Borneo concessions is grounded in experience. Its departure from a remote forest area in Bakhuis Mountains of Suriname last year was followed by large-scale poaching for commercial bushmeat markets. The carnage destroyed the one of the world's most prolific camera-trapping projects for monitoring wildlife. A biologist working in the area called it a tragedy.

"This was the most tragic loss of a pristine habitat and wildlife I have ever witnessed," said the scientist, who asked not to be named. "I will forever remember the Bakhuis as the Lost Eden."

BHP Billiton and WWF, a conservation group that has worked with the governments of Indonesia, Malaysia, and Brunei to develop the Heart of Borneo initiative, were not willing to comment on this report.

With the clearing of forests, baby orangutans are marooned

(06/25/2009) The orangutans at the Nyaru Menteng center, run by the Borneo Orangutan Survival Foundation (BOS), are mainly “oil palm orphans” whose forest habitats were destroyed — and parents killed — by the swiftly spreading oil palm industry in Indonesia. BOS hopes to eventually release all of these orangutans back into their natural habitat — the majestic rainforests and swampy peat lands of central Kalimantan. But for many, this is a fate that may never be realized, and instead they may be relegated to a life in captivity. The reason? Suitable habitat in Borneo and Sumatra — the two islands that are home to the world's entire population of wild orangutans — is being deforested so rapidly that it is becoming increasingly difficult to find locations for reintroduction.

Moths defend against bats by 'jamming' sonar

Researchers have discovered that a species of tiger moth eludes bats by jamming their echolocation with ultrasonic clicks. The discovery, published in the journal Science, adds to the list of defensive mechanisms that insects use to defend themselves against bats.

Aaron Corcoran and colleagues used ultrasonic recording and high-speed infrared video to determine that the tiger moth (Bertholdia trigona) effectively thwart attacks from big brown bats (Eptesicus fuscus) using ultrasound that jams bat sonar. They found that the defense was "effective immediately and persistently" on the bats that "that frequently tried to capture the clicking moths but had much difficulty doing so." The bats continued their attacks despite their poor success in capturing prey.

The study is the first to demonstrate the use of sonar jamming as an predator avoidance mechanism by moths. Many moths rely on toxins to make them distasteful to bats or "startle" strategies to give them an opportunity to escape.

FORCES BEHIND FOREST LOSS

As the first seven sections of this site have described, tropical rainforests are incredibly rich ecosystems that play a fundamental role in the basic functioning of the planet. Rainforests are home to probably 50 percent of the world's species, making them an extensive library of biological and genetic resources. In addition, rainforests help maintain the climate by regulating atmospheric gases and stabilizing rainfall, protect against desertification, and provide numerous other ecological functions.

However, these precious systems are among the most threatened on the planet. Although the precise area is debated, each day at least 80,000 acres (32,300 ha) of forest disappear from Earth. At least another 80,000 acres (32,300 ha) of forest are degraded. Along with them, the planet loses as many as several hundred species to extinction, the vast majority of which have never been documented by science. As these forests fall, more carbon is added to the atmosphere, climactic conditions are further altered, and more topsoil is lost to erosion.

Despite increased awareness of the importance of these forests, deforestation rates have not slowed. Analysis of figures from the Food and Agriculture Organization of the United Nations (FAO) shows that tropical deforestation rates increased 8.5 percent from 2000-2005 when compared with the 1990s, while loss of primary forests may have expanded by 25 percent over the same period. Nigeria and Vietnam's rate of primary forest loss has doubled since the 1990s, while Peru's rate has tripled.

Overall, FAO estimates that 10.4 million hectares of tropical forest were permanently destroyed each year in the period from 2000 to 2005, an increase since the 1990-2000 period, when around 10.16 million hectares of forest were lost. Among primary forests, annual deforestation rose to 6.26 million hectares from 5.41 million hectares in the same period. On a broader scale, FAO data shows that primary forests are being replaced by less biodiverse plantations and secondary forests. Due to a significant increase in plantation forests, forest cover has generally been expanding in North America, Europe, and China while diminishing in the tropics. Industrial logging, conversion for agriculture (commercial and subsistence), and forest fires—often purposely set by people—are responsible for the bulk of global deforestation today.

Tropical rainforest of the world.

Tropical rainforests are a world like none other; and their importance to the global ecosystem and human existence is paramount. Unparalleled in terms of their biological diversity, tropical rainforests are a natural reservoir of genetic diversity which offers a rich source of medicinal plants, high-yield foods, and a myriad of other useful forest products. They are an important habitat for migratory animals and sustain as much as 50 percent of the species on Earth, as well as a number of diverse and unique indigenous cultures. Tropical rainforests play an elemental role in regulating global weather in addition to maintaining regular rainfall, while buffering against floods, droughts, and erosion. They store vast quantities of carbon, while producing a significant amount of the world's oxygen.


Despite their monumental role, tropical forests are restricted to the small land area between the latitudes 22.5° North and 22.5° South of the equator, or in other words between the Tropic of Capricorn and the Tropic of Cancer. Since the majority of Earth's land is located north of the tropics, rainforests are naturally limited to a relatively small area.


Tropical rainforests, like so many other natural places, are a scarce resource in the 21st century. The vast swaths of forest, swamp, desert, and savanna that carpeted Earth's land surface a mere five generations ago have been reduced to scattered fragments; today, more than two-thirds of the world's tropical rainforests exist as fragmented remnants. Just a few thousand years ago, tropical rainforests covered as much as 12 percent of the Earth's land surface, or about 6 million square miles (15.5 million square km), but today less than 5 percent of Earth's land is covered with these forests (about 2.41 million square miles or 625 million hectares). The largest unbroken stretch of rainforest is found in the Amazon river basin of South America. Over half of this forest lies in Brazil, which holds about one-third of the world's remaining tropical rainforests. Another 20 percent of the world's remaining rainforest exists in Indonesia and Congo Basin, while the balance of the world's rainforests are scattered around the globe in tropical regions.


The global distribution of tropical rainforests can be broken up into four biogeographical realms based roughly on four forested continental regions: the Ethiopian or Afrotropical, the Australiasian or Australian, the Oriental or Indomalayan/Asian, and the Neotropical.

Range extended for world’s most mysterious gorilla

The Wildlife Conservation Society (WCS) announced yesterday the discovery of eastern lowland gorilla nests in an unexplored area of the Democratic Republic of Congo (DRC), expanding the range of this little-known subspecies by 30 miles (50 kilometers).

The eastern lowland gorilla, also known as Grauer’s gorilla, is currently listed as Endangered in the IUCN Red List. Scientists estimate that the gorilla has as few as 8,000 individual left. Although closely related to mountain gorillas, the eastern lowland gorilla is the world’s largest living primate, weighing over 500 pounds at maximum, and is endemic to the DRC.
Researchers surveyed the unexplored region in the DRC, known as Itombwe forest, during a calm period between the DRC’s government and rebels group, which use Itombwe for its rich natural resources.

“Today’s announcement that Grauer’s gorillas inhabit forests in Itombwe more than 50 kilometers south of their previously known range gives hope for the survival of the subspecies and a renewed impetus for protecting this extraordinary biodiversity area in the Albertine Rift of Africa," said Dr. James Deutsch, Director of WCS’s Africa Programs.

Along with evidence of the eastern lowland gorilla, researchers also discovered a new frog and toad species that are in the process of being described. In addition, the survey found indications that chimpanzees also had a larger range than previously believed.

"The findings of our survey will be important to conservation efforts for eastern lowland gorillas and their habitat, primarily because so little is known about this subspecies." said Dr. Andrew Plumptre, Director of the WCS’s Albertine Rift Program. "In particular it will help us in the development of plans for the demarcation of boundaries for the Itombwe Reserve, which is in the process of being created."

The announcement of the eastern lowland gorilla’s expanded range was made yesterday at the Gorilla Symposium, a conference organized by UNEP-Convention on Migratory Species of Wild Animals, the German Ministry for the Environment, the Ministry for Economic Cooperation and Development, and the Frankfurt Zoological Society at the Frankfurt Zoo in Germany.

869 species extinct, 17,000 threatened with extinction

Nearly 17,000 plant and animal species are known to be threatened with extinction, while more than 800 have disappeared over the past 500 years, reports the International Union for Conservation of Nature (IUCN). The group warns that governments will miss their 2010 target for reducing biodiversity loss.

"When governments take action to reduce biodiversity loss there are some conservation successes, but we are still a long way from reversing the trend," says Jean-Christophe Vié, Deputy Head of IUCN's Species Program and senior editor of Wildlife in a Changing World, a report based on analysis of the 44,838 species on the IUCN Red List.
"It's time to recognize that nature is the largest company on Earth working for the benefit of 100 percent of humankind – and it's doing it for free. Governments should put as much effort, if not more, into saving nature as they do into saving economic and financial sectors."

The report shows that 869 species are "Extinct" or "Extinct the Wild" (rising to 1,159 if the 290 "Critically Endangered" species listed as "Possibly Extinct" are included) and at least 16,928 species are threatened with extinction. While these numbers are substantial, they are likely "gross" underestimates since only 2.7 percent of 1.8 million described species have been assessed. Scientists estimate there are 10-100 million species on Earth.

The report found some plant and animal groups to be particularly vulnerable. One third of amphibians, nearly a quarter of mammals, 27 percent of reef-building corals, 17 percent of sharks and rays, 29 percent of conifers, and 52 percent of cycads are threatened with extinction.

"The report makes for depressing reading," says Craig Hilton Taylor, Manager of the IUCN Red List Unit and co-editor. "It tells us that the extinction crisis is as bad, or even worse, than we believed. But it also shows the trends these species are following and is therefore an essential part of decision-making processes. In the run-up to 2010, the global community should use this report wisely to address the situation."

The report notes that the proportion of species at risk is expected to rise with as the planet warms. Land use change due to human development will interfere with migration to safer elevations and latitudes.
