Pioneering Historian of Science and Explorer of the Greater Bird of Paradise

Alfred Russel Wallace

A Pioneer of Natural Selection and Biogeography

Alfred Russel Wallace, often overshadowed by Charles Darwin, was a groundbreaking scientist whose work shaped our understanding of evolution and biodiversity. Here’s a concise look at his key contributions:

In 1858, while in the Malay Archipelago, Wallace sent Charles Darwin a paper outlining his theory of evolution by natural selection. This prompted the joint publication of the “Wallace-Darwin Letters,” introducing the world to the concept. Wallace’s independent discovery highlighted the importance of ecology in understanding evolution.

In 1859, Wallace proposed the “Wallace Line,” an imaginary line separating the distinct faunal regions of Southeast Asia and Australia. Running through the Malay Archipelago, between Borneo and Sulawesi, and between Bali (in the west) and Lombok (in the east). It revealed how geography influences species distribution. This concept became a cornerstone of biogeography, showcasing the unique biodiversity of the region.

Wallace’s eight-year exploration of the Malay Archipelago culminated in his 1869 book, The Malay Archipelago: The Land of the Orangutan and the Bird of Paradise. He documented the relationship between species and their environments, offering early insights into how ecology shapes evolution. His work also hinted at ancient, submerged landmasses, linking species distribution to Earth’s geological history.

Unveiling the Secrets of the Bird of Paradise: Wallace’s Legacy in Conservation

Alfred Russel Wallace, the pioneering naturalist whose explorations in The Malay Archipelago unveiled the wonders of Southeast Asia’s biodiversity. From the lush forests of Borneo to the remote islands of New Guinea, Wallace’s work not only advanced natural science but also shed light on the urgent need for conservation—especially for the iconic bird of paradise.

The Myth of the Bird of Paradise

In the 18th and 19th centuries, the bird of paradise captivated European imagination. Its dazzling feathers symbolized luxury, wealth, and status, adorning hats, dresses, and formal wear. Yet, Wallace revealed a stark truth: Europe’s fascination was built on myths and misconceptions.

Through his travels (Malaya, Nicobar Island, Philippines, Solomon Island, out of New Guinea), Wallace introduced the world to the bird’s true habitat—its native forests in Papua and the Aru Islands. He debunked the romanticized tales of the bird floating in eternal flight, emphasizing its ecological role and the need to protect its fragile existence.

The Dark Side of the Feather Trade

Wallace’s observations exposed the devastating impact of the wild bird trade. European demand for feathers drove uncontrolled exploitation, with local hunters overharvesting the birds to meet foreign markets. Wallace noted the lack of regulations and the toll this took on the bird’s populations.

He highlighted the irony: while Europeans marveled at the bird’s beauty, they knew little about its life in the wild. The bird of paradise became a symbol of luxury, but at the cost of its survival.

 

Wallace’s Call for Conservation

Wallace’s work was more than scientific discovery—it was a call to action. He documented the ecological importance of the bird of paradise and warned against the dangers of unchecked exploitation. His insights laid the groundwork for modern conservation efforts, reminding us of the delicate balance between human desires and nature’s needs.

Today, Wallace’s legacy lives on as we strive to protect the bird of paradise and its habitat. His journey through The Malay Archipelago not only refuted myths but also inspired a deeper understanding of our natural world.

The Pig-Nosed Turtle: Balancing Tradition and Conservation in Papua

Have you ever heard of the pig-nosed turtle (Carettochelys insculpta)? This unique species, with its distinctive pig-like snout and flipper-like limbs, is one of nature’s most intriguing creations. Found in the freshwater rivers and estuaries of northern Australia and southern New Guinea, this turtle is not only a marvel of evolution but also a symbol of the delicate balance between human activity and wildlife conservation.

Endangered Species

The pig-nosed turtle is the only living member of its family, Carettochelyidae, making it a true evolutionary oddity and also listed as an Endangered species by the IUCN.  But there is someone who is threatening the survival of this endangered species by collecting eggs from its nest: local communities.

Every year, female pig-nosed turtles emerge onto sandy riverbanks to lay their eggs. These nesting sites are often located on customary lands in Southern Papua, where indigenous communities have harvested turtle eggs for generations. For these communities, the eggs are a valuable resource, providing both food and income.

In regions like the Kao River, the collection of pig-nosed turtle eggs is a well-established tradition. Local residents, often from clans that hold customary rights to the land, are the primary harvesters. These individuals are not only skilled hunters but also experts in locating turtle nests hidden beneath the sand. Using generations of knowledge, they carefully dig up the eggs, ensuring that none are damaged in the process.

The Challenge of Sustainable Harvesting

Based on Papua Conservation Program team’s field survey and interview, In regions like the Kao River, it’s estimated that up to 69,000 pig-nosed turtle eggs are harvested each nesting season. Harvesters, collect every egg from the nests they find. While the primary focus is on the eggs, some adult turtles are also taken for personal consumption.

Interestingly, the sale of pig-nosed turtles is not in the form of eggs but as hatchlings. This means that harvesters must incubate the eggs themselves, either at makeshift camps or in their villages. While this practice ensures a steady supply of hatchlings for the market, it also highlights the need for sustainable harvesting practices that prioritize conservation.

The Indonesian government had declared the pig-nosed turtle a protected species and recommended a national harvest quota of 10,000 in the form of eggs, with harvesting sites in Mimika and Asmat.

Only one company has been granted a permit to collect eggs from nature and incubate the eggs. There is a clear imbalance between the quota and the number of eggs collected by local people.

A Balancing Act: Tradition and Conservation

The pig-nosed turtle faces a unique challenge. On one hand, its eggs are an important resource for local communities, deeply tied to their cultural and economic practices. On the other hand, unchecked harvesting could threaten the species’ survival. So, how do we strike a balance?

A mechanism is needed to allow the community to engage in legal harvesting without compromising economic gain and conservation benefits. We also need to improve awareness. If communities can understand the value of this species in the ecosystem and the sense of stewardship, it may be possible to release half of the hatchlings back into the wild.

Final Thoughts

The pig-nosed turtle’s story is a reminder of the complex relationship between humans and nature. It challenges us to find ways to coexist with wildlife, respecting traditional practices while ensuring the survival of vulnerable species.

Factors for Habitat Loss of Pig Nosed Turtle in South Papua

There are causes of impact on the life of the pig – nosed turtle habitat, by adjusting from the Indonesian Government Regulation (P.106 / MENLHK / SETJEN / KUM.1 / 12/2018) written on page 25 in table number 697 of the Carretochelydae group or Carretochelys insculpta (https://jdih.maritim.go.id/cfind/source/files/permen-lhk/permenlhk-nomor-p.106-tahun-2018.pdf). As well as the existence of Appendix II status as a case of International Trade Species. However, in Indonesia it is often found as a case of exotic animal trade, food markets and believed to be a traditional medicine practice, and beauty cosmetic ingredients, as a result habitat exploitation occurs intensively in Papua, the occurrence of twenty cases in the exact period 2013 to 2020. And one case was found in 2022.

The following are samples of evidence of illegal trade obtained by the authorities:

The perpetrator is threatened with the regulation of article 21 paragraph 2 letter d in conjunction with article 40 paragraph 2 of Law number 5 of 1990 concerning KSDAHE (Conservation of Biological Resources and Ecosystems).

The defendant was sentenced to four months imprisonment by the Merauke District Court with a fine of Rp. 5,000,000 (if unable to pay, a two-month prison sentence will be substituted). This is lighter than the original prison sentence of eight months.

The status of the pig nosed turtle is listed by the IUCN as threatened with extinction, the biggest impact is due to the illegal trade that exceeds the maximum quota requirement of the Indonesian Government Regulation even though the statement of the Indonesian Government Regulation on pig nosed turtle is already a “Hunting Animal”, but it is obliged to follow the harvest quota that is used maximum of 10,000 eggs.

In fact, exploitation in the field, in South Papua (based on the results of research by the Papua Conservation Team in 2022) there are communities (harvesters/hunters) 69,000 eggs from (23 clans x 3000 eggs) which are used as income opportunities by being sold out of Papua illegally. There is also a community representative storing the harvest of 4,000 eggs, one month (In August) the harvest gets 2,000 eggs. Stored in a special container.

The biggest impacts of endangered threats, include:

  • Human disturbance (the largest) caused by illegal trade (exotic animal markets, food markets, strong medicine ingredients, beauty cosmetics ingredients) not using Indonesian Government Regulations. In Indonesia, illegal trade is found and arrested every year, often in August, September, October, during the harvest season.
  • Climate change resulting in failure to hatch eggs in the sand, river flooding resulting in eggs in the nest breaking and drowning.
  • Natural disturbances caused by invading animals in nature (monitor lizards), and so on.

Conservation needs organized by Papua Conservation

The results of the procurement of collaboration with IPB and TSE Group for the conservation of the Papuan ecosystem, the state of the pig nosed turtle population synergizes with the culture of the Papuan people which has been immortalized by the “Papuan People’s Ancestors. In order for people to understand retrieved between wildlife populations and their culture, deeper research and campaigns should be conducted that direct people to follow government regulations on the education of restrictions on Harvesting, Selling, Utilizing eggs and pig nosed turtle.

As well as, a ranching program that utilizes pig nosed turtle eggs legally. (Half of the people’s use of pig nosed turtle eggs, there are 50% in nature and 50% used by the Papua people’s needs for sale) Delivered by the Indonesian Government Regulation (SK. Minister of Environment and Forestry No. 65 / MENLHK /KSDAE /KSA.2 / 3/2021 dated March 3, 2021).
