Let’s keep common species common

One day, back in 2014, at the Central Department of Environmental Science, Tribhuvan University, 19 aspiring wildlife biologists, who had taken Wildlife Conservation and Management as a major, were discussing the human influence on biodiversity, wildlife species in particular. The late Man Kumar Dhamala, who was moderating the class as a faculty, gave an example of a species—Bengal Fox. According to him, the species, which was quite common a few decades earlier, is experiencing tremendous pressure and is declining rapidly despite having a wide dietary niche. Among the 19 folks, only one person, Narayan Niraula, who also hailed from Jhapa like the late Dhamala, said he knew about the species while others had no idea. Later on, Narayan Niraula went on to conduct his Masters dissertation to explore the conservation ecology of Bengal Fox in West Jhapa. As far as I know, thus far, this is the only dissertation written in Nepal with Bengal Fox as primary subject. This highlights the attention that this species has received from wildlife biologists in the country.

Bengal Fox

Bengal Fox, a member of the Canid family, is a medium-sized carnivore species known to occur in Nepal, India, Bangladesh and Pakistan and is endemic to South Asia. The range of the species is reported up to an elevation of 1,500m, however, the claim is still debated. There is a report claiming the record of the species from Lamtang National Park, however, as the species has not been recorded in mid-hills and the Himalayan Range, the case could be one of misidentification.

Bengal Fox mostly live in the interface of agricultural fields and forests and they usually avoid heavily forested areas. They are an omnivorous species with a wide dietary niche, consuming arthropods, rodents, reptiles, fruits and birds. This dietary niche means, Bengal Fox can have wider adaptability and significant impact to balance the ecosystem.   

Threats to Bengal Fox

In a recent assessment conducted in 2016, the global population of Bengal Fox was listed as least concerned species in IUCN Red List. However, the species is facing diverse forms of threats. As the species has not been studied well, we do not have ample evidence to prove the threats facing it. However, there are incidental records of Bengal Fox killed in road accidents and some records of poaching. Furthermore, the species prefers the small scrubs or short grassland; nowadays they usually build dens in the Agricultural field, escalating the threats to the species.

Back in 2016, when I was at Sundarpur area of Udayapur district for my dissertation, I noticed a den of Bengal Fox in the middle of the paddy field. One person was nearby and I had a conservation with him, who admitted that the species is causing the damage to the field and people usually damage the den and try to kill the species. 

Furthermore, the species is widely hunted in parts of Nepal for food. According to Narayan Niraula, some indigenous groups like Satar regularly hunt and consume the species in Jhapa. Given its status in Nepal. “Status of Nepal’s Mammals: The National Red List Series” has listed the species as vulnerable (VU).  

In Nepal and elsewhere, hunting on localized scale for trade of skin, tail, teeth and claws for medicinal and charm purposes is rampant. Furthermore, they undergo population fluctuations due to prey population cycles and disease outbreaks. In some cases, they may undergo local extirpation.

Local extirpation

On 2 July 2022, I was chitchatting in Tanahun with one of my relatives in his early 60s. We were discussing how the environmental factors, especially wildlife and their distribution, have changed. He recalled his childhood and teen years when the animal called “Khyak” that looked like a jackal but was smaller than them was common in Khairanitar of Tanahun district.  Back then, the Kumal community, an indigenous group known for their clay pot making skills, used to set the animals’ den afire and kill them. 

The species is extinct now, according to him. Based on his description, I thought the species could be Bengal Fox. When I wrote a post on social media, especially Facebook, stressing the need for conversation of the species, I received many comments. Narayan Niraula said that the species is known with different names in local dialects such as Khirkhire, Khek Shyal and Khekri. Sagar Dahal, a wildlife biologist, who works on research and conservation of small mammals, informed that Kanchan Parajuli from Hetaunda, Makwanpur district, had once spotted the species in Khairenitar (Kaski district) and taken its pictures. The elevation range of Khairenitar is nearly 600m, meaning the climatic condition was suitable for the species. 

According to Shashank Sharma, who was doing a PhD on Common Leopard, in the survey of nearly 600 sq km across Tanahun, Lamjung and Kaski, he had found no trace of the Bengal Fox. He adds, even the Asiatic Golden Jackal were also missing. This highlights the fate of wild canids as a whole.

Conservation measures

Owing to threats resulting from international trade in the species, India has kept the population of Bengal Fox in their country in Appendix III of Convention on International Trade of Endangered Species of Wild Fauna and Flora (CITES). However, the Bengal Fox Population in Nepal has not seen any such measures. 

Way forward

As we lack information about the species in Nepal, it is essential to establish a baseline. Thus, the first initiatives should be exploring the distribution of the species and the threats facing them in those areas. Furthermore, based on the baseline, we need to plan and implement tailored conservation measures. Drawing from the concluding lines of the late Dhamala’s lectures, I reiterate here that all conservation biologists should aim to keep common species common. We all have to work together to keep Bengal Fox common.
