African swine fever ravaging Borneo’s wild bearded pigs

African swine fever has reached the island of Borneo, where it is wiping out populations of the wild bearded pig Sus barbatus. First confirmed in early February, the outbreak has driven a precipitous decline in this species in less than two months. Field sites in the east of the Sabah region are reporting a complete absence of live pigs in forests. Local extinctions across swathes of Borneo are a realistic prospect.

Bearded pigs are listed as vulnerable by the International Union for Conservation of Nature. They are seen as ‘ecosystem engineers’ in the Bornean rainforest, where they are one of the most abundant species of mammal. Bearded pigs can be legally hunted under permit, and are an important source of animal protein for many communities.

The African swine fever virus is already island-hopping across southeast Asia, threatening 11 species of endemic pig, including the Sulawesi warty pig (Sus celebensis). Opportunities to control the disease in wild-pig populations are limited. Vaccines for domestic pigs are still in development, so the best hope for stemming loss of the wild animals could be to protect isolated populations in geographically defensible locations.

Very concerning indeed.

I first read about it a while ago on Mongabay but it is very worrying how quickly it is now spreading across South-East Asia.

Not only SE Asia. Endemic infection with African swine fever has already reached India. Number of endangered pig species might grow.

Based on experience here in Europe, it´s impossible to eradicate this virus from wild boar in areas where domestic pigs are infected because of constant spill-over. In warmer climate like in Bulgaria, spread of virus seems to accelerate by flying insects (flies). Even careful spacial isolation with double fencing and high hygiene simply doesn´t work during warm part of the year.
 
This is really upsetting news. What is the likelihood that this outbreak will cause Bearded pigs to be switched from Vulnerable to Endangered? Possibilities of things like this happening is why I never felt it was smart for Taxonomic Advisory Groups to decide on phasing out Bearded pigs. As I have said on here before, this is why I believe every wild animal and plant species, subspecies and distinct population segment when and where possible needs to have a captive insurance population.

Yes, I know it will pose a risk to efforts with the pygmy hog in Assam.

Very depressing indeed.
 
That does sound concerning...

Definitely, but I think I remember reading that the captive breeding center for this species in Assam are in lockdown and taking a lot of bio-security precautions.

What do you think about the lack of Bornean bearded pigs in captivity / zoos given this latest outbreak of swine fever and mass mortality of the species in the wild ?
 
What AZA and EAZA zoos phasing out Bornean bearded pigs (Sus barbatus barbatus) reminds me of what happened in 1989 when Steve Wylie was the Director of the Oklahoma City Zoo and shipped out their last remaining Russian saiga (Saiga tatarica tatarica) to the private sector, saying that they are doing well in the wild as justification. After the collapse of the Soviet Union, saiga populations drastically declined and now they are critically endangered and decreasing. I realize how much of a large ambitious undertaking this is, but as I have said on here before, that is why I am of the belief that every wild animal and plant species, subspecies, and distinct population segment when and where possible should have a captive insurance population.
