TURTLE LIVE


On a sunny morning at Bali’s Nusa Dua beach, 240 sea turtle hatchlings got a little help from friends to begin a journey traveled by their ancestors for millions of years.

Local officials of Badung Regency and members of the Kuta Turtle Conservation Group, the Serangan Turtle Conservation Group, and Conservation International (CI) were joined by curious onlookers in releasing the tiny olive ridley and green sea turtles into the ocean as a side event at U.N. climate change talks on the Indonesian island.

The baby turtles, smaller than your hand, scampered on their flippers across the sand and into the water, watched and in some cases prodded by throngs of onlookers and a large international media contingent.

"These species have no passport, so they migrate all over the world," event co-organizer Ketut Sarjana Putra, marine director for CI’s Indonesia program, told the crowd by loudspeaker.

He cited the threats they face wherever they go: ill-planned coastal development that destroys nesting beaches; natural predators on land and sea, including humans who eat the turtles and their eggs; and garbage and other pollution.

Now climate change poses a potentially more devastating threat, he said. Rising ocean levels mean the loss of more nesting beaches, while warmer temperatures affect the reproduction process by causing more females than males to hatch. Eventually, such an imbalance will doom affected species, Putra said. He suggested a mitigation strategy: plant more coastal trees to provide shade for the turtle nests, keeping them cooler.

The olive ridley (Lepidochelys olivacea) is listed as Vulnerable and the green sea turtle (Chelonia mydas) as Endangered, meaning threatened with extinction, by the IUCN. They are most vulnerable as eggs incubating in nests on the beach, and then when they hatch and scramble to their ocean home. The hatchlings released on Bali were from eggs kept in protected nests, then allowed to reach the ocean free of preying birds and other threats.

"They have a less than 1 percent chance of surviving to adulthood," Putra noted. "We’re just trying to give them a little help here at the start."

The turtle release was one of several events by host Indonesia to emphasize the nation’s remarkable biological diversity during the U.N. talks on a blueprint for confronting climate change. In previous days, Indonesian President Susilo Bambang Yudhoyono announced a new Orangutan Action Plan, and more than two dozen captive-bred Bali starlings (Leucopsar rothschildi) were released in a national park to more than double the population in the wild of the Critically Endangered species.

Sumatran tiger conservation
Tigers were once distributed widely across forests and grasslands from Turkey to Siberia in the northeast to the Indonesian island of Java in the southeast. This vast historical range has been greatly reduced in the last 200 years through habitat loss, depletion of tiger prey by growing human populations, and tiger eradication campaigns. In Indonesia, the Javan and Bali tigers were driven to extinction in the last 60 years. Only the Sumatran tiger remains, with viable populations restricted to just a few protected areas on the island. A failure to carry out vigorous conservation campaigns to protect remaining tigers will mean the loss of one of the world’s most ecologically important top predators, and one of our most charismatic flagship species for biodiversity protection at large. WCS Indonesia has been working to protect Sumatran tigers in Bukit Barisan Selatan National Park (BBSNP) since 1998.

The Human Aspect
BBSNP, which stretches 150 km along the Barisan Mountain Range in southern Sumatra, is ringed by human settlements. In fact, Lampung Province, in which most of the park lies, is the most densely populated province on Sumatra. As such, local people and tigers interact indirectly—and sometimes directly—in and around the park on a daily level. In effect, tigers and people in the BBSNP area compete for resources, such as lowland rainforest and game.

Threats
Habitat loss, prey loss, and poaching are major threats to tigers in BBSNP. The first is of great concern, as it affects not only tigers, but all of the park’s lowland-dwelling species. One-fifth of the park’s total forest cover has been lost to human encroachment, and the destruction continues at an average rate of 4.85 km2 per month. The second threat, the decline in sambar deer and wild pig populations, is the result of heavy hunting in and around the park. Shrinking prey populations have been cited as a major cause of tiger declines in many Asian countries. The third, poaching of tigers, is driven by a local and international demand for traditional Chinese medicines, and also includes trophy hunting as well as retaliatory acts in response to killing of livestock or humans by tigers. BBSNP’s tiger population is only about 40-43 animals; every tiger that is killed or dies of starvation counts.

WCS Activities
Our current approach to tiger conservation in and around BBSNP has four components, as follows.

  • Ecological research and monitoring: Since 1998, we have monitored tigers and their prey via camera trap. Our work has been the first to demonstrate that camera trap data is a good measure of the relative abundance of these populations, and has helped us to gauge their health.
  • Habitat protection: WCS is coordinating a multi-year project called CANOPI that brings together park authorities, local governments and NGOs, and community groups to protect tigers and other key wildlife and their habitats in the broader Bukit Barisan Selatan landscape. A major focus of the program is to develop and promote sustainable livelihoods that will alleviate deforestation and unsustainable agricultural practices in the area. In addition, our landscape ecology project uses a combination of remote sensing and ground surveys to monitor deforestation, identify its major components, and provide detailed reports to the national park authority to help fight encroachment.
  • Conflict awareness and education: Our tiger team is working with communities around the park to collect information on human-tiger conflict. The team is working side by side with local people to develop solutions to the problem, including innovative “tiger-safe” approaches to maintaining livestock.
  • Collaborative law enforcement: WCS operates a Wildlife Crimes Unit in southern Sumatra to monitor and investigate trade in Sumatran tigers and other protected species in the area, provide legal support in the prosecution of wildlife law offenders, and promote awareness of prohibitions against tiger trade.

Important Next Steps

  • Build a national Wildlife Crimes network: This will include (1) mounting a national lobby and media campaign to raise awareness of wildlife laws and to increase the harshness of sentences against offenders, (2) increasing coordination to fight wildlife crimes at the national and regional level through building capacity in the Department of Forestry, and (3) reducing national demand for illegal wildlife.
  • Promote partners in Sumatran tiger conservation, including the Indonesian Department of tiger conservation through partnership: We plan to bring together Forestry and other local and international organizations working on Sumatra. By pooling knowledge and resources, this partnership network will strengthen existing infrastructure to conserve Sumatran tigers and will expand efforts to monitor tigers and decrease human-tiger conflict throughout southern Sumatra.

Conservation & Elephant Hunting


The African elephant is a natural resource that lends itself to assignable ownership and that ownership, couples with benefits produced from hunting, provides an incentive for conservation. There are other uses of the African elephant, both legal and illegal, but the purpose of this article is conservation and elephant hunting.

Regulation has often been utilized as the final solution to conservation problems. In fact, conservation rarely directly results from unqualified regulation, because regulation restricts or removes ownership. Appropriate regulation limits use, but sets the boundaries for the implementation of management practices at the appropriate levels. That is why the victory for the elephant at the 1997 CITES Meeting in Harare was so significant; it did not preclude applied management; it made it a requirement.

Hunting of the African elephant by foreign tourists has a long-standing tradition and is one of the uses of choice by many African nations today. Africans were hunting elephants before Eastern peoples or Europeans arrived in Africa. Elephant hunting by foreigners generates both finances for management and with the emphasis on local people in management, it has increasingly begun to provide incentives to the people living with the wildlife.

We conserve only what we have incentives to conserve. Wildlife has three economic values. Legal value is the value assigned with regulated use. Illegal value would be the use outside of laws or regulation (for instance, poaching). No value means that the resource will effectively be ignored. Sadly, most evaluations of use focus on the negative impact of the use (the faulty precautionary principle), ignoring the impact of not using the resource. Any real evaluation must include those costs to the resource of not using it. Conservation practices require funding, and that funding must come from somewhere, to turn from a use providing benefits must be factored into any evaluation as a very real cost.

Elephant management requires determining the appropriate level of sustainable off take, and that management requires funding. With increased value of any resource, comes a responsibility, and more likely an imperative need for increased level of management. But conservation cannot (more appropriately put, will not) be perpetually performed in a financial vacuum. In a world beset by many demands for land, if a species is to survive, a use which can be sustained both economically and ecologically, provides independence that will favor survival in the most tumultuous of times.

Hunting of elephants by tourists is cost effective, profitable and easily monitored. The foreign hunter pays for all participation in the hunt, including government fees, and for taking the natural resource. A government representative is usually present. Animals are taken under a quota. The stakeholders in such an arrangement include the hunter, the professional hunter (guide), the regulatory agency (National Parks or Wildlife) and the people who live with the elephants (the community).

Imaginative approaches are being implemented in the different hunting countries such as Zimbabwe's CAMPFIRE communities collecting data and setting their own harvest quotas. In South Africa, many ranches have their own herds of elephants. Other countries such as Cameroon, Botswana and Tanzania are implementing programs where hunting benefits communities. Tying in the management to those who benefit provides an appropriate monitoring loop in management.

In conservation, as in governmental structure, centralization reduces effectiveness. Since all ecological and economic systems are dynamic, good conservation is the ability of the management to adapt to that change. Local monitoring with the control to adapt to that change decreases response time. This results in a more appropriate level of adaptive management.

The elephant is a natural resource with assignable ownership. Foreign hunters are willing to convert that from an asset to capital in exchange for a cultural experience compatible with the history and use of the elephant. It is the responsibility of the hunter to demand an ethical experience and the professional hunter to provide such an experience. It is the responsibility of those charged with management to maintain the resource. It is the responsibility of the regulatory agencies, while maintaining appropriate boundaries, to minimize their restriction of management options for any dynamic resource.

International hunting of elephants will continue to be a realistic option for sustainable utilization. Under well managed conditions, it provides economic incentive for continued proper management, and this insures the survival of the elephant. And that by definition is conservation - the wise use of natural resources.

Komodo dragon conservation in Indonesia


Now the ZSL conservation programme has assisted research into the wild population and distribution patterns of this exciting reptile.

Komodo dragons are the world’s largest living lizard and are found predominantly on the islands of Flores, Rinca and of course Komodo in Indonesia. The latter two islands enjoy the protection of lying within the Komodo National Park, but Flores is outside of the park boundaries and as a result the dragons on this island receive only rudimentary protection.

Research in 2004 helped to calculate an estimate of the dragon population on the tiny island of Gili Motang in the south east corner of the National Park. This island has a relatively low density of the dragon’s favourite prey, the Rusa deer, and as a result the dragons are not only reduced in number but appear to be physically smaller in stature than their cousins on Rinca and Komodo.

In August 2005, Dr Claudio Ciofi from Florence University, ZSL Curator of Herpetology Richard Gibson and a senior ranger from the Indonesian Department of Forestry surveyed an area of coastline in north-eastern Flores. Though dragons are known from the west coast and from a small area on the western north coast of this much larger and now heavily populated island, the survey area was beyond the known range of the dragon.

Sadly, two weeks of intensive trapping, searching and talking to the local people confirmed that dragons had indeed inhabited the area in the past, perhaps as recently as five years ago, but no evidence of their continued survival could be found.

It is therefore highly probable that the dragons of Flores have suffered a local extinction in this part of the island, apparently due to habitat loss, annual fires set by people to help them flush-out and poach the few remaining deer, and general disturbance of the area by a growing human population.

This sad news is an important wake-up call for the protection of dragons elsewhere in Flores. Fortunately a pilot project has been initiated in west Flores to re-establish the Wae Wuul Nature Reserve. This long-term project is co-ordinated by Claudio and Richard on behalf of a consortium of European zoos who keep dragons in captivity. Together these zoos fund the project combining infrastructural development, social awareness and environmental education programmes, warden patrols and legislative enforcement, and annual dragon population census.

With luck this project may prove to be a model for an expanded programme to protect dragons and their habitat along the entire west coast of Flores, a global biodiversity hotspot supporting countless endemic plants, insects and birds as well as the magnificent Komodo drago.

Orangutan Survival


We want you to participate in this worldwide event. Help build a “critical mass of concerned voices” each November to focus attention on the species through your efforts and those of other supporters.

We would like people to come to understand that the habitat of the orangutan, the tropical rain forest, is vital to not only orangutans but to other wildlife and to all of us on this planet. Rainforests and related ecosystems provide important services from climate moderation, to water quality and erosion control, to storehouses of genetic, species and ecological biodiversity. Rainforests need to be sustainably managed to maintain these services. We want to inform citizens in our own communities of this connection and continue to enlighten local people in areas near orangutan habitat.
