‘Wildlife’ generally refers to animals and plants found in the wild, not domesticated or cultivated. The term encompasses species naturally occurring in their habitats, as opposed to those brought into captivity and selectively bred over time.
‘Forensic,’ derived from Latin meaning ‘public,’ pertains to matters of law.
‘Wildlife Forensics’ utilizes forensic science to protect and conserve non-domesticated animals, including those in natural habitats and captivity, as well as plants and their ecosystems.
‘Wildlife crime’ refers to offences threatening wild animals, plants, or habitats, breaching national, regional, or international laws. This includes crimes involving domesticated species, such as animal cruelty cases or using animals as evidence in criminal investigations.
Scope of Wildlife Forensics
Legal disputes involving wild animals, whether they are in their natural habitats or kept in captivity, are becoming more common across various regions, including Europe, North and South America, Australasia, Africa, India, and the Far East. Consequently, these animals may also be subjected to forensic examination.
Wild animals (free-living or captive) are involved in legal cases in three main ways
- Be the cause of an incident – for example, if they injure a person, damage property, or spread an infectious disease.
- Be the victim – an animal that is killed, injured, poached, illegally exported, or subjected to inhumane treatment.
- The animal is discovered dead under circumstances that are unusual, unexpected, or suspicious.
- The animal is alive, but its symptoms appear to be abnormal, unexpected, or suspicious.
- The animal’s welfare is currently or has been compromised.
- There are indications that the animal has been unlawfully captured, killed, or held in captivity.
- Provide information that is relevant to an incident – for example, because they were present when a crime was committed and their hair or other material remains as evidence.
Animals of different species, alone or in groups, have the potential to inflict injuries, cause death, and result in financial losses. Wildlife forensic cases may involve wild animals, domesticated animals, and humans. E.g., a pet dog may be responsible for killing or maiming a protected species.
Methods in Wildlife Forensics
The methods utilized in wildlife forensics closely resemble those employed in other criminal investigations. Typically, forensic cases in this field involve a combination of the following methods:
- Inspecting the alleged crime scene and evaluating any findings or observations.
- Gathering information primarily through interviews with individuals involved in or related to the incident.
- Examining live animals.
- Inspecting deceased animals.
- Gathering and identifying evidence, including derivatives and samples, for laboratory analysis. This may involve a certain amount of fieldwork.
- Ensuring proper transportation of specimens to the laboratory for analysis.
- Conducting laboratory tests.
- Properly storing and presenting evidence.
- Generating reports based on findings.
- Providing expert testimony in court.
- Preserving materials for potential further legal proceedings or for future reference.
The Tools of the Trade
In wildlife investigation, a range of forensic techniques are employed to gather evidence and uncover the mysteries surrounding crimes involving animals. Some key methods and how they are adapted to wildlife cases are below:
- DNA Analysis: DNA analysis extracts genetic material from samples like blood, hair, feathers, or feces to identify species, individuals, or genetic traits. Crucial in wildlife cases, it helps trace the origins of confiscated items, identify endangered species in illegal trade, and link suspects to crimes.
- Fingerprinting: Fingerprinting analyzes unique patterns to identify individuals. In wildlife cases, experts use techniques like footprint analysis to identify species and link suspects to crime scenes. Comparing footprint impressions from poaching sites can reveal both perpetrators and species involved.
- Chemical Analysis: Chemical analysis tests samples for toxins, pesticides, or pollutants. In wildlife cases, it determines causes of death, assesses pollution impacts on wildlife health, and identifies illegal substances in poaching. For instance, analyzing lead in scavenging bird tissues identifies lead poisoning from ingesting ammunition fragments.
- Other Methods
Pathology: Examining tissues and organs to diagnose diseases, injuries, or trauma in wildlife.
Isotope Analysis: Determining the geographic origin, diet, and migration patterns of wildlife based on stable isotopes in tissues.
Geospatial Analysis: Using GIS and satellite imagery to map habitats, track animal movements, and detect illegal activities like deforestation or habitat destruction.
Forensic Entomology: Studying insect colonization on carcasses to estimate the time of death and gather evidence in wildlife crime scenes.
