Endangered Species Monday: Papustyla pulcherrima
Manus Green Tree Snail – Very first invertebrate to be listed on the Endangered Species Act of the United States of America (2015) Endangered Species Post Special Report.
This Monday’s Endangered Species Post (ESP) I take a wee glimpse into the life of the Green Tree Snail, also commonly known by Papua New Guinea’s natives as the Manus Green Tree Snail. Image Credit: Stephen J. Richards.
Identified by Professor Rensch 1931, Rensch was born on the 21st January 1900 in Thale in Harz and died on the 4th April 1990 in Münster, (Germany), Professor Rensch was an evolutionary biologist, zoologist, ethologist, neurophysiologist and philosopher and co-founder of the synthetic theory of evolution. He was professor of Zoology and Director of the Zoological Institute at the Westphalian Wilhelms University in Münster. Together with his wife Mme Ilse Rensch he also worked in the field of Malacology and described several new species and subspecies of land snails.
The Manus Green Tree Snail is identified as Papustyla pulcherrima commonly known as the Emerald Green Snail. From 1983-1994 this particular species of snail was considered (extremely rare). Back in 1996 when scientists managed to again finally catch up with this stunning little mollusk, the species was then listed as (data deficient) of which to date there remains little information about this (rare) but beautiful snail.
P. pulcherrima is endemic to the Papa New Guinea northern island of Manus of which the species is listed as (near threatened), and has also been reported on the adjacent Los Negros Island. Environmental scientists have confirmed from villagers on the main Manus Island that the species is not located anywhere else. However there are some sketchy reports that the species “may be located on surrounding islands”, however there is no evidence to back these claims up.
Environmental scientists have confirmed for now that the species is located in only 12-13 areas of the Manus Island[s]. Further reports have confirmed that mature individuals are on the decline (which if not controlled could evidently see the species re-listed as vulnerable or endangered). The Manus Green Tree Snail is not believed to be living within fragmented zones. The species is restricted to forest and low intensity garden ‘type’ habitat. Declines have been noted within all 12-13 identified habitats on the Manus Island and adjacent Los Negros Islands. Population history is pretty much undocumented although has been shown to be slowly declining.

Back in 1930 when Professor Rensch identified the Manus Green Tree Snail, locals soon began collecting the species for trade thus seeing the mollusk now nearing endangered listing. Demand for the Manus Green Tree Snail has now drastically increased threatening the species furthermore. Locals continue to collect this rather unusual colored species shell for use within the jewelry trade. There are now “very serious concerns” that trade may eventually push the species into extinction.
Due to mass trade exploitation the Manus Green Tree Snail is the very first invertebrate to be listed on the Endangered Species Act of the United States of America. International trade has been controlled by export permit since 1975 under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) appendix II. Unfortunately this is not stopping locals from harvesting the species, and trade is still continuing despite it now a criminal offence under United States and some international laws.
“Overexploitation threatens the Manus Snail”
Market sales data collected from the Lorengau market, over a six day period suggest that annual sales at the market may approach 5,000 shells. Investigations by the Wildlife Conservation Society (WCS) reveal that large quantities of shells are still being attempted to be exported out of the country. Online searches revealed the sale of the shells, often marketed as antiques, occurring in open forums and internet market places based in New Zealand, Australia, and the United States of America (USA). International Animal Rescue Foundation has ran numerous traces online of which located yet again Ebay as being a number one trading site of the “threatened species”, please view the image below and click the image link that’ll direct you to that site.
“EBAY JAPAN IS A HOTBED FOR ILLEGAL TRADE OF THE MANUS GREEN SNAIL”
International Animal Rescue Foundation’s External Affairs Department and the Environmental Cyber Crimes Unit located many a sites trading the Manus Green Tree Snail’s shell which is illegal under some trade law, unfortunately the Ebay site listed above, located within Japan is one of many more that are trading (despite the species nearing extinction).
I.A.R.F’s Environmental Cyber Crimes Unit have since filed a complaint with Ebay, providing all the relevant data to now remove these species from their sites, however its likely to prove negative as the trader could very well state they harvested or purchased the shells before international laws were drafted. Furthermore a trace of the owner that owns this site above which is in violation of the United States and Cites laws (is located within the United States). So in regards to enforcement, breaking this link is going to be somewhat of a tough cookie. Further trade was witnessed here via what we can only believe is alleged “antiques”.
Further trade all of which is illegal has been recorded hereto – this site linked back to a Mr Rob West of 121 Henderson Road, Sheldon, Brisbane, Queensland 4157 Australia, Telephone: 610732061636. Mr West from Brisbane categorically states that he doesn’t own a shop, and is a one man band, yet clearly this link states otherwise. Further evidence revealed antique trade conducted on the Ebay site, see in the image below (illegal under United States law).

“Illegal to trade under the Endangered Species Act of the United States of America”
The environmental wildlife crimes investigation team linked to TRAFFIC and Cites stated:
It is possible the avoidance of conventional nomenclature is an attempt to avoid detection by authorities. In some cases, sellers on internet market places were based in CITES signatory countries (including: Australia, Italy, New Zealand, Singapore and USA) while others were not (e.g. Taiwan). Currently, volumes of shells on sale in such online market places appear low, suggesting that the existing controls on international trade maybe adequate. However, given that the online prices of shells were often orders of magnitude greater than market prices on Manus Island, vigilance will be required to insure that illegal international demand does not fuel a resurgence in snail collection.
Despite the massive trade on Manus Green Tree Snails online and within open Asian markets, its literally impossible to determine if this trade will eventually lead to the species being pushed into extinction. However it MUST be noted that there are currently only 12-13 identified habitats that the snail currently inhabits. And based on traces online conducted by the I.A.R.F’s External Affairs Department – trade is most certainly “out of control”, and not as Cites has reported (2012).
The shell of this species is a vivid green color, which is unusual in snails. The green color is however not within the solid, calcium carbonate part of the shell but instead it is a very thin protein layer known as the periostracum. Under the periostracum the shell is yellow.
The Manus Green Tree Snail is mostly threatened by habitat destruction through forest clearance: logging, plantation development (especially rubber) and to a lesser extent road developments. Increasing human population growth and an increasing cultural demand for deriving cash incomes from the land will likely see the rate of forest degradation increase in the future. Harvest occurs when trees are felled as part of traditional shifting cultivation and the snails, typically found in the canopy, suddenly become exposed. Such harvesting is not uncommon but it is likely to be of lower significance than the longer term habitat degradation caused by such agricultural practices.
While harvest for illicit international trade is occurring, the volumes are not “allegedly” thought to be large compared to historic rates, although they may approach levels seen in the legal domestic trade. However, given that the prices of shells internationally are often orders of magnitude greater than market prices on Manus Island, vigilance will be required to insure that illegal international demand does not fuel a resurgence in snail collection.
Notable deposits of gold have been found in central Manus and a mine operation will likely result in the next decade although no details of the plan have been released (as of 2014). The forests of Manus Island were badly affected by the 1997-1998 El Niño which resulted in a prolonged drought. Should climatic change result in increased rates of similar conditions this may constitute a future threat to the snail species, however, current predictions suggest that future incidence of drought in Papua New Guinea will decrease (Australian Bureau of Metrology and CSIRO 2011).
Despite the reassurances from Cites, WCS and the local wildlife organisations – evidence clearly points to large scale online trade legal and illegal. Furthermore there is no telling if shells online are antique or smuggled from the Manus Islands which is very concerning.
Manus Green Tree Snail is the first such snail to be listed on the threatened list of endangered species (USA). Research also explains to us that its likely the species will be plundered into extinction – very soon. Enjoy the video.
Thank you for reading, and please be most kind to share to create awareness and education.

EMBASSY DAY: 17TH SEPTEMBER 2015 WWW.SAYNOTODOGMEAT.NET
Did you know on the 17th September 2015 from 11:00am the Australian organisation www.saynotodogmeat.net, registration 49 860 343 527 will be hosting peaceful demonstrations around the globe within nine major cities? Embassy Day forms the first (governmental) lobbying in relation to #OperationUnite 2016. Embassy Day will be the organisations second largest demo since April 4th 2015. Back in April Say No To Dog Meat made history by hosting the worlds largest anti pet meat demo in over twenty five countries.
On the 4th April 2015 the Say No To Dog Meat family hit the streets internationally in their thousands marching for dogs and cats in the horrific pet meat trade. The main April protests were non-governmental, however was a reminder that should the (eight governments) the organisation are lobbying not respond to the polite requests from the Aussie organisation. The next step would be Embassy Day, September 2015. Finally after Embassy Day, the organisation will then begin gearing up for phase two of Operation Unite 2016 that will be held October 2nd and 3rd 2016. Followed up with #OperationUnite comes the new #lovefamily campaign too.

September 17th 2015 will see demonstrators lobbying South Korean embassies within Los Angeles, United States and Ottawa, Canada. Then in New York the Indonesian embassy, followed up with the Cambodian embassy in Seattle, United States will be demonstrated. Meanwhile within the United Kingdom the Vietnamese embassy will be peacefully protested in London, followed up with the Indian consulate in Belfast, Northern Ireland. The Nigerian embassy in Johannesburg, South Africa will follow soon after. The Thailand consulate within Perth and Philippines consulate in Brisbane, Australia will be peacefully lobbied too.
Donna Armes, campaign manager and director confirmed that all embassy consulate generals and ambassadors had been sent communications months before Embassy Day was planned. Furthermore the campaign manager stated a second electronic communication had been sent and received by embassy staff informing them about the peaceful protests, and why the organisation has been forced to lobby all nine embassies. Embassy staff, consulates and ambassadors have failed to acknowledge the Aussie organisations peaceful plans which is a little frustrating but then the organisation didn’t expect a reply anyway.
Say No To Dog Meat volunteers and directors will begin the ‘peaceful demonstrations’ with an up to date speech on current and past issues in relation to both ‘Asian and African’ dog and cat meat trade outside of each embassy. After the main speech the public can stay or depart of which the organisations volunteers and directors will then be handing into the embassies all data and petitions.

Each petition contains from 10,000 to 200,000 signatures. Statistics on pet meat consumption death rates, virus and disease, regulations and violations of current standing law, predictive model data research, food hygiene violations will be handed into the consulate generals and ambassadors too. Presidential letters will also feature within the pack of which each government has a set six to eight months to respond. The organisation is not expecting an immediate or even positive response, of which OPERATION UNITE will continue to go ahead come October 2016.
For the very first time in history the Indian and Nigerian embassies will be lobbied by the organisation in relation to the Indian, Nagaland and Nigerian pet meat trades. Nigeria is the largest dog meat consuming country on the continent of Africa and third largest on the planet. Furthermore deaths from consumption of diseased or rabies infested pet meat has skyrocketed this year alone with some eighty people dead already. Meanwhile the Indian Nagaland state loses on average an estimated forty people a year via the direct consumption of rabies infested dog meat. Rabies is also on the rise in both pet meat consuming zones. India is where 85% of all human rabies deaths occurred between 1995 and 2004. Over this period there were 21404 rabies deaths a year there. Death rates for 2014 are yet to be seen.
“About 3.5 million dog bites are registered every year in India. The Government cannot give vaccine free of cost to all people. From 2006, the price of vaccine has increased…”
Despite many protests against the South Korean Bok Nal pet meat trade that began in June and ended in the first week of August. The South Korean government took no notice of expert knowledge, scientific data or petitions handed to them. Instead they allowed traders to continue the horrific disease riddled trade, and took little notice of their own laws and guidelines implemented to protect dogs and cats in meat trade. Dare we ask what the point is in introducing animal protection laws, just to allow native citizens to continue violating them?
From 2013-2015 Say No To Dog Meat has vainly lobbied the Viet Nam health minister and president Trương Tấn Sang to bring an end to the pet meat trade. On the 19th August 2014 reports issued by the (World Health Organisation) confirmed that deaths rates had increased slightly to forty (per year), however its estimated that some one hundred people die annually from rabies infection.
Despite the Aussie organisation sending more than enough scientific evidence to the Vietnamese health minister and president the trade continues. From 1995-2004 the then death rate from rabies in Viet Nam stood at some 1,550. Since 2004 the Vietnamese pet meat trade has increased. Death rates continue to increase within the country from the direct consumption of diseased pet meat, statistics from 2014 showed many of these deaths were infant related either bitten by dogs on private land or from consuming rabied infected dog and cat meat.
March 16th 2009 the Vietnamese government were handed third party data from; National Institute of Infectious and Tropical Diseases and the National Institute of Hygiene and Epidemiology in Hanoi, Viet Nam that stated; “Most Rabies deaths in Vietnam were from the direct Butchering and eating of either dog or cat meat”.
Vietnamese researchers confirmed;
“In Viet Nam, dogs with rabies have been detected in dog slaughterhouses and workers at dog slaughterhouses are vaccinated against rabies as part of the national programme for rabies control and prevention. However, the private slaughter of dogs is relatively common in the country which increases rabies infection rates”
“Vietnamese doctors already consider dog slaughtering to be a risk factor for rabies transmission, but it is important that other health care workers and policy makers, both in- and outside Vietnam, are aware of this risk factor”
Dog and cat meat trade is now finally illegal within Thailand, unfortunately this doesn’t stop traffickers from snatching dogs and transporting from Thailand into the Viet Nam. Yes the trade may indeed be illegal, but again our own investigative journalists have located street traders openly selling and smuggling unhygienic meat in rural communities.
Back in 2013 [Life With Dogs] stated; “In the past week, Cambodia, Laos, Thailand and Vietnam have signed a deal with the intention of ending the importation and sale of dogs to be used as food. This move was initiated by their governments because of the involvement of animal welfare group Asia Canine Protection Alliance. The ACPA is comprised of four notable animal groups: Animals Asia, Change for Animals Foundation, Humane Society International and Soi Dog Foundation.
We are now in 2015 and as yet [SpeakupFortheVoiceless] and [SayNoToDogMeat] have yet to witness any such decrease of trade within Cambodia, Vietnam and Laos. Trafficking and snatching of pet dogs and cats continues within Thailand feeding the trade within the Viet Nam and China. Why has it taken from 2013 to do nothing? One only has to walk the streets of Hanoi, Saigon, Hoi An and Ben Tre to witness dog meat traders more than active. On June 30 2015, police from Sakol Nakorn intercepted a truck carrying the butchered remains and carcasses of more than 100 dogs. The truck was heading for Tha Rae, [the traditional home of Thailand’s dog meat trade]. Yet trade is illegal!
Within the Philippines the government has introduced tough and stringent laws with regards to pet meat traffickers and peddlers (Please click the links to view current data from government). Say No To Dog Meat recognizes the Philippines as one of few Asiatic countries on the continent that has taken the pet meat trade seriously. Despite a law banning the killing and maltreatment of dogs (Animal Welfare Act of 1998), dog-eating and the industry that supplies it continues particularly in the northern part of the country. Back in June 23 2013, some 12 dogs were rescued in San Pedro Laguna, according to the Department of Agriculture (DA).
The Philippines government aims to eliminate the country’s dog meat trade by 2016, AKF Head and Legal Counsel Heidi Caguioa told Rappler . Eradication means no more dog meat traders and no more dog meat restaurants. Say No To Dog Meat will be lobbying the Philippines embassy within Brisbane, Australia calling on the government to strengthen the current Animal Welfare Act 1998 and Rabies Act 9482.
Finally Say No To Dog Meat volunteers will be lobbying the Indonesian embassy calling on the government to enact law and close down all known dog meat markets. The Indonesian dog meat trade is allegedly associated with the Minahasa culture of northern Sulawesi, Maluku culture and the Bataks of northern Sumatra, where dog meat is considered a festive dish, usually reserved for occasions such as weddings and Christmas. While Say No To Dog Meat and our comrades Animal Defenders Indonesia, Surabaya Tanpa Dog Meat, Bali Adoption and Rehabilitation Center would like to believe this, the trade on dog and cat meat actually occurs every day of the month.
This September 2015 please unite with Say No To Dog Meat this Embassy Day 2015. For more information please contact the organisation here via email: firstname.lastname@example.org
