Altering the Horn to Save the Rhino

The life and death of today’s rhino revolves around its horn. Being hunted to the brink of extinction for their horns, conservationists and scientists are trying to find ways to use the horn to save them.

Rhino Horn Facts:
1. It is made of compressed keratin, much like horse hooves, cockatoo bills, fingernails, etc.
2. Rhino horns grow throughout their lifetime, at a rate of 1-3 inches per year
3. Baby rhinos are born without horns.
4. There is no scientific evidence to support rhino horn being effective in curing medical ailments.


An obvious and tried solution to the poaching crisis has been to de-horn rhinos. The thought being if there is no horn, there is no reason to harm the rhino.

This has produced mixed results. While some reserves have seen success, for others rhino were still poached AFTER the de-horning.

The process is risky to the animal. It is an invasive procedure, and as with any situation involving immobilization and anaesthetic, there is always a risk of complication. The process removes 90-93% of the horn, and needs to be repeated every 12-24 months.

It is also quite costly. Per Save the Rhino, current published estimates for de-horning range from $620 USD (Kruger National Park) per animal to $1,000 (private land).

Sadly with such a phenomenal price tag on the horn, that 7-10% still makes them a target for poachers. Sometimes intentionally, sometimes not  (in the darkness, they may not realize the rhino is de-horned until they have killed it).

So when considering this as an option, the risks need to be weighed. Is the rhino in a high-target poaching area? Is there enough security and monitoring to back up the procedure?

Horn Injections

The more recent method, developed by the Rhino Rescue project has been to make the horn less desirable by injecting it with a toxin.

Ectoparasiticides are used in conjunction with a dye. The ectoparasiticides are safe for animals, but not consumable to humans. If ingested, they cause digestive issues.  Once poached, it is this pinkish dye that conveys to users it is a tainted horn.

Around the perimeter of rhino areas, would-be-poachers are warned of the dye-injected horns.

Although still requiring an anaesthetic, it is less invasive and only needs to be updated every 3-4 years. In addition it is fairly cost-effective when compared to other alternatives.

Initially it seemed an effective deterrent.

However In May of 2014, there were claims disputing it’s effects. The report by South Africa wildlife experts implied the dye “failed to deeply penetrate the high-density fibre of the horn.” This controversial report angered many who wondered at the wisdom in publicizing the findings.


In 2013, the WWF donated microchips to the Kenya Wildlife Service. The chips were planted in every rhino in the country.

The system works by implanting one microchip in the horn and another in the body. This, along with their rhino DNA database, helps to keep track of the animals. If a horn is found anywhere in the world, it can be traced back to the area of the poaching.

According to KWS, “This will serve to strengthen rhino monitoring, protect the animals on site and also support anti-trafficking mechanisms, nationally and regionally.”

Chips for RHINOS! and It’s not the kind you EAT..:)


Microchips to protect Rhinos in Kenya –

Nairobi, Kenya – Efforts to conserve Kenya’s dwindling population of rhinos is set to get a significant boost when WWF-Kenya hands over 1,000 microchips and 5 scanners to the Kenya Wildlife Service (KWS) today. The equipment valued at over KES 1.3 million will be instrumental in strengthening active rhino monitoring as well as stockpile audits (of rhino horn).

With poachers getting more sophisticated in their approach it is vital that conservation efforts embrace the use of more sophisticated technology to counter the killing of wildlife. The deployment of specialized rhino horn tracking systems combined with forensic DNA technology will allow for 100% traceability of every rhino horn and live animal within Kenya. This will serve to strengthen rhino monitoring, protect the animals on site and also support anti-trafficking mechanisms nationally and regionally.


Furthermore, investigators will be able to link any poached case to a recovered or confiscated horn and this forms crucial evidence in court contributing towards the prosecution’s ability to push for sentencing of a suspected rhino criminal. These technologies are now being used internationally in support of criminal justice responses to wildlife crime as well as strengthening inter-agency collaborations (between customs, police, justice, wildlife agencies and defense).

At a continental and worldwide level, these technologies will expose the rhino horn trade chain and facilitate the dismantling of the networks that promote and sustain the International Wildlife Trade (IWT).
