Dire declines in the wild populations have endangered red pandas to a point where they are at risk of extinction in the wild. According to the IUCN, “Populations have plausibly declined by 50% over the last three generations (estimated at 18 years) and this decline is projected to continue, and probably intensify, in the next three generations.”
Found in several countries, their habitats are often in hard-to-access locations, making data collection on them difficult. This leads to credible sources differing on the numbers remaining in the wild, with some stating that only 2,500 remain in the wild, while others maintain that the number is 10,000. However, estimates of the numbers remaining have been low enough to capture the attention of the IUCN, which, in 1994, changed its status from “Insufficiently Known” to “Vulnerable” and then to “Endangered.”
Habitat Loss and the Red Pandas’ Fight for Survival
The threats to the red panda’s survival in the wild are the loss and degradation of their habitats. Red pandas’ destruction is primarily deforestation, as forests are cleared for timber, agriculture (livestock), and development. Conservation strategies like wildlife corridors to connect fragmented habitats could enable red panda movement and breeding between populations. Boosting overall population numbers is critical to creating a genetically robust species that can withstand future threats.
Government-imposed protections to habitats have helped where enforced, but even with these in place, projections are that 70% of Nepal’s red panda’s habitat is not protected. Even where there are large protected areas, enforcement is often weak, and human influences continue to result in declining populations.
Small Population Genetics
With estimated wild populations under 10,000, red pandas suffer from a lack of genetic diversity and face risks of inbreeding depression. This hampers efforts to keep populations healthy over the long term. Habitat fragmentation exacerbates the problem by isolating groups. Small isolated groups also experience high levels of inbreeding, resulting in birth defects and infertility. Maintaining connectivity between populations could help preserve genetic diversity and a healthy population.
Climate Change
Climate change is causing changes in temperature and precipitation patterns. As temperatures rise, the tree line shifts higher up the mountain, reducing the number of suitable habitats for red pandas, and bamboo forests disappear. Losing their homes and food sources makes it difficult to survive.
Changes in rainfall patterns can also lead to droughts or floods, further reducing the availability of suitable habitats, disrupting the distribution of the bamboo that red pandas rely on for their diet, and significantly impacting the red pandas’ habitats. These events destroy or damage large bamboo forest areas, leading to food shortages and increasing the risk of red panda predation. Higher temperatures and drier seasonal conditions also result in increased numbers of forest fires, which also take their toll.
Poaching and Trapping
In many habitats that are the homes of red pandas, there is active poaching and trade for their distinctive pelts, fur, and other parts in red pandas, as they are greatly valued. An instance of this type of red panda trade is detailed in the South China Morning Post, which describes a police raid where hundreds of kilos of body parts of pandas and other wildlife were discovered. Inadvertent deaths and suffering also occur when traps are set for other animals, such as deer and wild pigs, ascendingly capture and kill red pandas.
Disease
Where red pandas and humans share the same habitat, dogs safeguarding livestock against potential predators can transmit up to seven types of gastrointestinal parasites to red pandas and spread the highly contagious and deadly canine distemper virus into red panda populations, a significant threat. These dogs also attack and kill many pandas, even when they are not a threat to livestock.

The red panda’s diet is 95% bamboo leaves – habitat destruction reduces available bamboo and the survival of this species.
Increasingly strict laws in India, Bhutan, Tibet, China, Myanmar (Burma), and Nepal are on the books as attempts to reign in the threats and save the remaining wild red pandas. Though the laws and regulations exist, inadequate public awareness and weak law enforcement practices often have left less than desirable results.
