Wildlife Forensics: Science in the Service of Conservation

Wildlife forensics deals with non-human evidence, but it adheres to the same principle as traditional forensic science, which typically deals with human crime: scientific proof for justice.

Wildlife Forensics = Science + Law + Conservation.

Objectives of Wildlife Forensics

Species Identification

identifying if a commodity confiscated (such as flesh, skin, feather, horn, wood, etc.) is a member of a protected species.

 Example: Recognising ivory as a phoney alternative or elephant tusk.

Individual Identification

comparing the genetic profile or DNA of animal parts that have been seized to recognised populations or individuals.

Geographical Origin

tracking the origin of the plant or animal.  (African versus Asian elephants, for instance).

Cause of Death

figuring out whether the animal was shot, poisoned, poached, or died naturally.

Law Enforcement Support

providing scientific evidence to support the prosecution of criminals by organisations such as the WCCB, CITES, and Interpol.

Techniques Used in Wildlife Forensics

Wildlife forensics is multidisciplinary, using tools from biology, chemistry, genetics, and even digital science.

1. Molecular & Genetic Techniques

• DNA Barcoding

  • Uses a short genetic sequence (usually mitochondrial COI gene) to identify species.

  • Example: Distinguishing between tiger and leopard skin, or between genuine ivory and cattle bone.

• Mitochondrial DNA Analysis (mtDNA)

  • Useful for degraded samples (bones, hair, teeth, feathers).

  • Helps trace maternal lineage.

• Microsatellite / STR (Short Tandem Repeat) Profiling

  • Identifies individual animals (similar to human DNA fingerprinting).

  • Used to match seized animal parts with poached carcasses.

• Next-Generation Sequencing (NGS)

  • Advanced method for analyzing mixed or degraded samples (e.g., bushmeat analysis)

2. Morphological & Anatomical Analysis

• Skeletal Studies – Analysis of bones, skulls, horns, and teeth.

• Feather Analysis – Identifying bird species by feather patterns and microstructures.

• Scale & Skin Studies – For reptiles and pangolins.

• Wood & Plant Anatomy – Used for timber forensics (red sandalwood, agarwood, etc.).

3. Chemical & Biochemical Analysis

• Stable Isotope Analysis

  • Identifies the geographical origin of wildlife products.

  • Example: Elephant ivory from Africa vs. Asia.

• Toxicology Tests

  • Detecting poisons, tranquilizers, or drugs used in killing animals.

• Protein-based Analysis (Immunoassays)

  • Identifying animal species from blood, meat, or tissue when DNA is degraded.
