Beyond the Clinic: How Vets Help Protect Wildlife

Most people imagine a vet's office, a stethoscope, and a sick dog or cat when they think of a veterinarian. The opportunities in veterinary medicine aren't limited to domestic animals. Veterinarians are involved in wildlife conservation through wildlife forests, rehabilitation centres, protected areas, laboratories, or even directly with conservation teams in the field.

They don't just take care of animals that are hurt. Wildlife health workers assist in disease surveillance, inquests into unusual mortality, aid in the rehabilitation of wildlife, conserve populations against adverse health impacts, and contribute scientific data that can influence conservation choices. When it comes to protecting individual animals' health, protection of species is often tied up in their protection.

Treating Injured and Sick Wildlife

Treating Injured and Sick Wildlife

A wildlife vet's most obvious function is to provide care for injured, orphaned, and sick animals.

The cause of injury to wild animals can be from vehicles, snares and traps, natural causes, human-wildlife conflicts, or poisoning. Veterinarians can check their health, treat them in an emergency, perform surgery if needed, and take care of their recovery.

But it's similar to a different objective for treatment at a regular veterinarian's office. When it is possible, rehabilitation aims to prepare an animal to survive in its environment. This includes physical, nutritional, behavioral, and disease prevention.

Therefore, for a successful release, more than the healing of an injury is required. The animal must be healthy enough to cope with the demands of life in the wild.

Watching for Wildlife Diseases

Disease can occur in an individual animal, or outbreaks can occur at a population level. Disease surveillance is therefore an important part of conservation work.

Biologists may take and analyze animal samples, examine sick or dead animal tissue, and study specific types of animals for symptoms of new diseases. These are activities that can be used to detect threats to health early on to be able to act before they develop into bigger issues.

According to the International Union for Conservation of Nature (IUCN), wildlife disease surveillance systems are capable of detecting new threats, assisting with conservation assessments, and managing disease.

Dealing with wild animals and examining them is especially difficult, as they are not routinely present. They may inhabit vast areas and/or be settled in places that are inaccessible to humans. Vets therefore frequently work closely with rangers, ecologists, communities, laboratories and wildlife authorities to obtain information.

Protecting Entire Populations

The next question a wildlife vet won't ask is “How do we treat this animal?” They may even ask, “Why are these animals getting sick?”

A wider perspective is key to conservation. For instance, domestic animals can contract and transmit disease to wildlife and vice versa, especially where domestic animals and wild fauna live together in the same areas. Veterinarians can play a role in recognizing them and putting in place preventive or monitoring actions to protect animals.

Welfare work for the benefit of individual animals has, however, evolved at IUCN Tiger reserves to include monitoring of disease, vaccination of livestock around the wildlife areas, investigation of deaths, and the response to threats like poisoning or snaring. Conservation of wildlife health can thus be done in the wild and also in specifically protected areas.

Supporting Wildlife Rehabilitation

Veterinary skills are paramount in rescue centres and rehabilitation facilities. Animals can be dehydrated, malnourished, and infected or seriously injured when they come to these facilities.

Treatment is determined by a veterinarian and is monitored in animals while they are recovering. They may also provide recommendations for nutrition, quarantine, infection control, and the releaseability of an animal.

This is particularly relevant if more than one animal is housed in a facility. Prevention can help ward off disease, as well as be beneficial for those animals being re-proven and for other wildlife populations.

Investigating Why Animals Die

Conservation can sometimes start with an animal's death.

A necropsy, or post-mortem examination, may be performed to discover possible causes of death and can be done by veterinarians. They can uncover infectious diseases, poisoning, injuries, nutritional disorders, or other threatening environmental factors.

These are the reasons they are important to understand so that conservation teams can respond appropriately. One death could be a worry, but multiple deaths with the same cause could be a sign of a far wider issue.

IUCN and the World Organisation for Animal Health (WOAH) highlight the importance of investigations and information sharing when conducting effective disease surveillance in relation to wildlife health events.

Working Across Disciplines

Solutions to most problems in wildlife conservation are not straightforward. Vets are thus joined by numerous other professionals and experts such as wildlife biologists and ecologists, epidemiologists, conservation managers, laboratory scientists, and government officials.

This dynamic is linked to the emerging concept of One Health, which acknowledges the interconnections of human, animal, and environmental health.

In its current Wildlife Health Strategy for 2026 – 2030, WOAH prioritises increased surveillance, prevention, scientific collaboration, and coordination between veterinary, environmental, and wildlife sectors in the management of wildlife health.

It is essentially the idea that a vet may provide some medical expertise, and an ecologist may conduct habitat analysis, while a conservation manager may focus on implementing in the field. Each point of view can contribute to the development of an understanding of the problem.

From Individual Care to Conservation

The relationship between conservation and veterinary medicine isn't always a simple one, but it isn't as straightforward as looking only at the individual animal.

Unfortunately, treating an injured leopard is important since that leopard matters. However, if you know why leopards are becoming unwell in an area, you might spot a disease before it breaks out in the population, or you might discover a regular wound that is affecting a population.

Wildlife veterinarians' work lies somewhere between animal care and animal conservation. Their work can assist in improving animal recovery, uncovering animal health problems that are not apparent, enhancing animal monitoring systems, and supporting decisions regarding conservation.

Preserving healthy habitats or ensuring that poaching is eradicated is not the only way to help protect wildlife. A healthy animal is also a key factor in a healthy ecosystem. Here, vets make a huge difference in helping animals live and thrive in their habitats through extra activities outside the clinic.
