Conservation Efforts to Save Endangered South China Tigers Members Public

The South China Tiger (Panthera tigris amoyensis) is the world’s most critically endangered tiger. Also known as Chinese, Amoy or Xiamen Tiger, the South China tiger subspecies is China’s only endemic tiger species. Historically roaming throughout southern China, estimates placed their numbers between 20,000 and 40,000 around 1900 and down to just 4,000 by the early 1950s.

Today there are no South China tigers left in the wild. The last sighting occurred in the 1990s. Many consider this critically endangered subspecies to be functionally extinct, but innovative conservation efforts to save these tigers from the brink of extinction are currently underway.

Unique evolutionary history

Scientists previously debated over whether modern tigers constitute two, five or six different subspecies. But a genome sequencing in 2018 of 32 specimens has led scientists to believe there are six different extant subspecies. Using statistical analysis comprised of 1.8 million DNA variants across the specimen tiger’s genomes confirmed the breakdown into six distinct subspecies: Malayan, Sumatran, Indochinese, Bengal, Amur (Siberian) and South China tigers.

Three other subspecies, first described in the 1930s, have already been lost to extinction: Caspian, Javan and Bali tigers.

It is believed that the South China tiger split and evolved from the oldest lineage of tigers, possibly making the South China tiger the original tiger from which all other current tiger subspecies evolved.

Poaching, habitat loss and traditional Chinese medicine

Tigers once held a mystical place in ancient Chinese culture. Western cultural influence in the late 19th and early 20th century helped change indigenous views of nature and the symbolic meaning of wild animals.

Western influence into China was underwritten by profits from the opium trade. The Chinese government’s resistance to the drug trade led to the Opium War (1839 - 1842), which China lost and as a result had to increase a number of treaty ports where the British could trade and live.

This led to extraterritorial rights to foreigners and an increase in Western missionaries and scientists through China’s backcountry, including Harry Caldwell, an American hunter and Methodist missionary from Tennessee.

Caldwell described his experiences in an autobiography as wanting to change local perceptions of wildlife, including ‘superstitions’ he vowed to destroy through hunting and preaching the gospel.

Caldwell saw tiger hunting as a “means for advancing the knowledge of the Christian God in the heart of Asia” and sought to refute the local belief of ‘spirit cats’ protected by local deities.

He noted that religious-based prohibitions against killing tigers were stronger than any possible game laws protecting wildlife would have been. Caldwell and other foreigners in Southern China employed locals as hunter guides and specimen collectors.

Caldwell went on to kill 48 South China tigers, which earned him the nickname “The Great Tiger Hunter.”

Around 1900, a shift in values and technology as well as a new market for wildlife parts and specimens were starting to form. This began the change in local perceptions of wild animals from supernatural beings to objects for scientific investigation, from a source of sacred medicine sold in local and regional markets to commercial commodities traded internationally.

As the Chinese Communist Party attained power after 1949, Mao Zedong’s ‘war on nature’ created new definitions of natural resources and led to a revolution in nature exploitation. Wildlife became a commodity to be exploited to serve the economic needs of the people.

Finally, “pest” killing campaigns in the 1980s eradicated about 3,000 tigers from their natural habitat. Rapid human population growth forced tigers and humans to live and hunt around each other, resulting in tigers being killed after violent encounters with people.

These killings supplied the demand for tiger parts used in traditional Chinese medicine at a time when China’s economic boom enabled affluent citizens to spend lavishly on expensive animal products. Adult tigers yield about 24 pounds of bones, which when crushed could sell for about $500 a gram.

Crushed tiger bone was often made into soup and sold to treat ailments like arthritis or into wine and sold as an aphrodisiac. Forelimbs fetched as much as $500 per pound. During this time Chinese tigers were being killed at the rate of about one per day.

The Wold Wildlife Fund estimated the majority of the $6 billion in illegal wildlife trade business went to tiger products like skin and bones.

The use of endangered tiger products in medicine is still seen as a symbol of high status and wealth. Some remedies that list tiger parts as an ingredient are so expensive, they often contain only trace elements. Yet even this is enough to promote the continued slaughter of tigers.

Conservation and rewilding efforts

In 1993, the State Council of the People’s Republic of China issued a ban on the trade of tiger bones. All domestic uses and bone trade were prohibited and tiger products were destroyed, including those meant to be used for traditional medicine.

In 1985, The Meihua Mountains Nature Reserve located in Fujian Province was established as a nature reserve for forests and wild animals, including the South China tiger. Around 51 South China tigers have been successfully bred in the reserve since the South China Tiger Breeding Research Institute was established in 1998.

Rewilding organizations like Save China Tigers work to introduce the South China tigers back into the wild. Wildlife conservationist Li Quan and her then-husband Stuart Bray, founded the Save China Tigers program in 2000 to raise awareness about the Chinese tiger's plight and protect it through public education, conservation models, and fundraising efforts.

In 2002, Save China Tigers partnered with the Chinese State Forestry Administration to establish The Laohu Valley Reserve, a private 140-square mile preservation reserve in South Africa built out of 17 retired sheep farms. Its chief goal is to teach captive-born South China tigers how to survive in the wild in a conservation process known as rewilding.

The Laohu Valley Reserve was once home to about 20 South China tigers, nearly 10% of the world’s population. It is unclear how many Chinese tigers currently reside there today.

The Chinese National Forestry and Grassland Administration plans to have 75% of its wild animals and 80% of its wild plants on land under the national key protection system by 2025.

Genetic biodiversity challenges

Despite the coordinated breeding program in China, conservationists face many challenges to save the South China tiger.

The lack of genetic biodiversity is the biggest challenge facing conservation efforts today. All South China tigers in captivity are descendants from just six individuals caught in the wild in the 1950s. This lack of genetic diversity results in high risk of genetic diseases. Cubs have been born with strabismus, facial deformities and suffer shortened life spans.

A study published in the Journal of Heredity in 2019 looked at 92 captive South China Tigers across 14 zoos in China. Of those, 18 were found to have genetic introgression from Bengal, Indochinese or Amur tigers. The study’s authors encouraged zoos to exclude these individuals from future breeding efforts.

Compounding conservation efforts is the difficulty in rewilding tigers bred in captivity for generations who need to be taught how to use their natural instincts to hunt.

Chinese zoos that loaned tiger cubs to Save China Tigers years ago face pressure to bring them back to China. Save China Tigers has also been mired in controversy. Li Quan accused Stuart Bray of misappropriating charitable funds in 2013.

The couple suffered a bitter and public divorce in 2014 with Stuart being acquitted of all charges and Li moving on to establish her own charity, China Tiger Revival.

Where to visit South China Tigers

There are around 200 South China Tigers left in the world, all in captivity. Most South China Tigers are predominantly in zoos throughout China, including:

Wangcheng Park Zoo - Housing the largest population of South China Tigers with 38 in total, this zoo is a successful breeding facility where two male cubs were born on October 3, 2020 through artificial breeding. The Wangcheng Park zoo is located in Luoyang City, in central China’s Henan Province.

Shanghai Zoo - The Shanghai Zoo has bred over 100 South China Tigers since 1958.

Suzhou South China Tiger Breeding Base - Located in east China’s Jiangsu Province and surrounded by mountains and jungles, it had about 14 South China tigers as of 2019.

Guangzhou Zoo - One of the three largest city zoos in China.

Changsha Ecological Zoo - The first artificially-bred South China tiger cub was born on January 20, 2022.

Meihuashan Institute of South China Tiger Breeding - Established in 1988, the number of South China tigers has grown from 3 to 39.

Other zoos in China where captive South China tigers reside include:

  • Chongqing Zoo
  • Chengdu Zoo
  • Fuzhou Zoo
  • Jiujiang Zoo
  • Zhongshan Park Zoo
  • Nanchang Zoo
  • Safari Park Guiyang
  • Safari Park Shenzhen

How you can help

Tax deductible monetary donations to wildlife conservation organizations are a straight forward way to help. Educating others and generally raising awareness about the plight of the tigers is the easiest thing anyone can do.

In addition:

  1. Avoid anything with Palm oil. It is found in many products and most is sourced unsustainably. Palm oil production is responsible for continued deforestation and ongoing habitat loss to tigers and other threatened wildlife. If you must buy a product with palm oil, make sure it contains the RSPO logo to ensure it was sustainably sourced.
  2. Fight climate change. Reducing your carbon footprint may seem like an ineffective drop in a giant bucket but collective, personal sacrifices add up.
  3. Visit only AZA accredited zoos. Avoid tiger petting facilities, which are often involved in the illegal wildlife trade.

5 reasons why critically endangered orcas are attacking boats on the Iberian peninsula Members Public

A critically endangered subpopulation of killer whales (Orcinus orca) from the Strait of Gibraltar is attacking boats and yachts crossing the Iberian Peninsula. In at least three documented cases, the boats were sunk. Nobody knows exactly why but here are some of the most interesting explanations.

1. Past trauma

Alfredo Lopez Fernandez, a researcher from Atlantic Orca Working Group, believes the pod’s matriarch, a whale they call White Gladis, was traumatized by something before the attacks of 2020.

An accidental collision with a rudder would explain why she attacks rudders. Researchers believe her violent behavior is being imitated rather than learned behavior from the juvenile whales attacking boats by targeting their rudder.

2. Food competition

The Iberian orcas associate boats with competition and food. They compete with local fishermen for Atlantic bluefin tuna, their main source of food.

They do so by actively hunting tuna until exhaustion or through longline depredation, which is when they take the fish off the fishing lines for an easy snack. There are records of whales wounded from commercial fishing lines, and many accounts of fishermen attacking orcas with harpoons.

3. Playful behavior

Dr. Deborah Giles, an orca researcher, thinks this behavior is playful in nature. Of the 15 whales observed ramming into vessels, 13 of them were young juveniles. When boats have been disabled and people are taken to safety, the whales leave. They don’t pursue or interact with the smaller vessels carrying people.

4. Temporary fad

Dr Luke Rendell, marine mammal researcher at the University of St Andrews, believes it is a temporary fad spread through social learning. He likens it to accounts of orcas mimicking sea lions, or captive orcas learning to regurgitate fish to use as bait for seagulls.

5. Injured orca calf

Fisherman Antonio Rodriguez thinks a sailor may have accidentally injured an orca calf and that’s why the whales are attacking the boats. Is life imitating art? The 1977 film Orca depicted a killer whale exacting revenge on a fisherman who killed his mate and unborn calf.

Last known Rafetus swinhoei female dies, leaving rare turtle species effectively extinct Members Public

One of the rarest turtles in the world is now functionally extinct. The last known female Yangtze Giant Softshell River turtle, aka Rafetus swinhoei, aka Hoan Kiem turtle, has died, conservationist Forest Galante announced on Instagram.

The 205-lb turtle was found floating motionless by locals and conservationists in Dong Mo Lake in late April, according to Vietnamese state media. An autopsy to identify the cause of death is underway.

These giant turtles were once abundant in the Yangtze River, but due to habitat loss, pollution, overfishing, and illegal poaching, their numbers have drastically declined over the past century. Only 2 living males remain. One is in captivity in China’s Suzhou Zoo and the other in the wild in Hanoi’s Xuân Khanh Lake.

Until last month, there was still hope that the female could be bred with one of the remaining males and perhaps save the species. “It was a large female that obviously has great reproductive capacity. She could have potentially laid a hundred eggs or more a year” Tim McCormack, director of Asian Turtle Program, told Time Magazine.

McCormack remains hopeful that there may be another female Rafetus swinhoei somewhere out there in Dong Mo Lake. If there isn’t, conservation efforts to save the species from extinction will be unsuccessful, as one of the two remaining males appears to be impotent.

Barring a miracle find in the Yangtze or Hanoi rivers, the future of the species now depends on de-extinction organizations like Colossal Biosciences and San Diego’s Frozen Zoo, which use molecular genetics to bring animals back from extinction. Tissues samples from the recently diseased turtle have been collected in the hopes that the Giant Yangtze Softshell turtle may one day survive in the wild.

COP15: Historic UN Biodiversity Conference, US just an observer Members Public

The United Nations held its Biodiversity Conference last month in Montreal, Canada. 188 representatives from the 196 states that signed on to the Convention on Biological Diversity (CBD) in 1993 were in attendance. As this was the 15th time they met, the Conference of the Parties was known as COP15.

Also present were the Vatican and the United States, the latter of which failed to ratify the CBD in 1992 due to Republican opposition in the Senate.

The US is one of four UN members to not sign onto the treaty. The others being Andorra, South Sudan, and the Holy See (the Vatican).

Why is it important?

At COP15, the UN Convention on Biological Diversity, adopted the Kunming-Montreal Global Biodiversity Framework, with a vision of “living in harmony with nature,” where by 2050 “biodiversity is valued, conserved, restored and wisely used, maintaining ecosystem services, sustaining a healthy planet and delivering benefits essential for all people.”

The Global Biodiversity Framework contains four long-term goals for 2050 and 23 specific targets for 2030, including:

By 2030…

• 30x30: Restore 30% of degraded global ecosystems on land and sea

• Conserve and manage 30% of areas

• Reduce risk from pesticides by at least 50%

• Reduce nutrients lost to the environment by at least 50%

• Reduce pollution risks and negative impacts of pollution from all sources to levels that are not harmful to biodiversity or ecosystem functions

• Reduce global consumption footprint through reducing overconsumption and waste generation

• Allocate $30 billion from developed to developing countries

• Reduce the rate of introduction and establishment of invasive species by at least 50%

• Ensure that the use and trade of wild species is safe, legal, and sustainable

• Reduce by $500 billion annual harmful government subsidies

By 2050…

• Stop the extinction of known species, and reduce the extinction risk and rate for all species tenfold

• Restore and enhance resiliency of all ecosystems

• Share funding and non-monetary benefits from utilization of genetic resources with indigenous and local communities

Scientists agree that decisions made at COP15 may be our last chance to curb the loss of biodiversity on earth.

Will this work?

Doubtful. More achievable goals were previously unsuccessful.

In 2002, the parties to the CBD agreed “to achieve by 2010 a significant reduction of the current rate of biodiversity loss”. They did not.

In 2010, they came up with 20 Biodiversity Targets for 2020, none of which were fully met. By 2018, they agreed to develop new targets under a Post-2020 Global Biodiversity Framework, which was just adopted at COP15.

Despite ambitious targets, biodiversity isn’t as sexy as climate change. There were no celebrities in attendance at COP15 and it didn’t get nearly as much media coverage as COP27, the UN’s climate change conference.

There are many reasons why biodiversity is in peril. Climate change gets all the headlines but all the problems are connected. The human population continues to grow, which continues to drive deforestation and overconsumption, particularly in the developed world.

Another challenge to biodiversity is our own diet. Too many of us eat beef. Livestock require large amounts of land on which to graze and grow crops for feed, resulting in more deforestation, not to mention the damage methane creates to climate change.

The $500 billion reduction in harmful government subsidies by 2030 could target agricultural subsidies and fishing fleets but that still falls short of the $1.8 trillion subsidies that are currently killing the planet.

In any event, the US was not a signatory to CBD, and is therefore under no obligation to meet any of those targets.

Unfortunately, unlike climate change, which is reversible, albeit incredibly difficult, extinctions are permanent. COP15 was a historic gathering to address biodiversity loss. But it wasn’t enough and it is unlikely to solve the problem as long as the US, the world’s largest economy, continues to sit on the sidelines.
