As of 2019, the Chinese Pangolin was listed in critically endangered status, with studies measuring the population size in rapid decline -- a >80% decrease is suspected over three generations.
In 1996, the Chinese pangolin was in "Near Threatened" status; twelve years later, it moved to "Endangered", and only six years after that assessment it was first marked as "Critically Endangered," where it remains today. Critical Endangerment is the last step on the IUCN Red List before a species faces extinction.
In 2002, populations in China were estimated at 50,000 to 100,000; by 2010, those estimates had dropped off by half. In 2015, scientists looked at twenty different nature reserves around southern China and found no fresh burrows or live animals during their survey.
It is estimated that more than 1,000,000 pangolins were trafficked over a ten-year period; this data indicates that
one pangolin is poached every three minutes.
In China, the largest threat facing the Chinese pangolin is that it is hunted (poached) for use in traditional Eastern medicine; its scales are thought to treat a variety of medical ailments, including skin conditions, improving blood circulation, and lactation stimulation in new mothers. Additionally, it is thought that pangolin scales are beneficial in cancer treatments. In addition to being prized for their scales, pangolins are also hunted and consumed as bush meat and eaten as a delicacy.
Other threats across southeast Asia include those related to habitat loss from an infrastructure development and environmental disturbance - including construction, hydropower development, and resource mining. well as an increase in pesticide use across the pangolin's habitats.
The largest international effort put in place to protect the pangolin species was done through the 1975 enaction of CITES - the Convention on International Trade in Endangered Species of Wild Fauna and Flora. CITES offers protection to more than 37,000 species of plants and animals that are traded across international borders. International trade of every species of pangolin is currently banned, though seizures of illegally traded goods are still being conducted. In 2018, stricter measures were defined by CITES to help combat illegal trading, including risk-profiling measures for port authority officials as well as an inventory tracking system to monitor stockpiles of pangolin scales.
Other partner organizations are also being called on in the fight to protect pangolins, including the International Consortium on Combating Wildlife Crime (ICCWC), to assist with analytical and investigational operations of the illegal pangolin trade across Asia. What is needed to further the efforts of these (and other) groups is compliance and enforcement of policies at the national and sub-national levels, and assistance by local community officials in maintaining the designated pangolin wildlife protected areas.
The World Wildlife Fund (WWF) has a photo gallery of products containing illegally-harvested pangolin leather, scales, and other body parts so that consumers know what to look for and report. If you suspect you've encountered a suspicious item made from protected wildlife, there is a tool available to report your finding:
Pangolins play a critical role in their ecosystems to the extent that they are known as guardians of the forest. They serve as important consumers in their food chains by bringing ecological balance as rampant insectivores - a single pangolin can consume enough insects to represent millions of dollars saved in pest control annually. They also serve as important tillers of the soil, assisting in turnover and aiding the decomposition cycle to improve the nutrient quality for further vegetative growth.
