Introduction Forensic - The application of scientific
knowledge to legal matters
Wildlife forensics is a relatively new field of wildlife criminal investigations.
Goals:1. Use scientific procedures to examine, identify, and compare evidence from wildlife crime scenes
2. Link this evidence with a suspect and a victim

Introduction cont’d…
Forensic science has a key role to play in curbing wildlife crimes
Illegal trade in wildlife and wildlife products affects the survival of species
Populations of rhinos and elephants havedeclined in recent years as a result of tradein their products.

Illegal trade in wildlife(1)The factors contributing to illegal trade in wildlifeand wildlife products
Poverty – unsustainable use
Human population growth and encroachment to wildlife areas
Ineffective legal deterrent measures
Low input costs involved in the trade
Deepening antipathy towards wildlife by landowners

Illegal trade in wildlife(2)
Issues that feature prominently in illegal trade on wildlife & their products
What is the identity of the specimen in question?
What is the provenance of the specimen in question?
What is the cause of death or injury?
Can a suspect be connected to wildlife crimescene?

WILDLIFE CRIMES IN KENYA.
• Kenya's invaluable wildlife resources are a target of illegal activities such as poaching and illegal exploitation.
• These illegal activities threaten the country’s wildlife resources and their habitats
• E.g

Bush meat tradeIllegal trade on a wide spectrum of wildlife products has become a serious threat and a major conservation challenge to Kenya Wildlife Service.

Forensics in wildlife conservation
Among the many fields of forensic science the most applicable in illegal trade in wildlife is Forensic Biology
Many forensic techniques can be utilized to investigate illegal trade on wildlife & other contraband products.
Forensic science can support effective enforcement of national wildlife legislation.
Forensic science has other wider applications in wildlife conservation
![Page 11: Forensic science in illegal trade on wildlife · Forensic science in illegal trade on wildlife Moses Otiende Molecular Biologist Kenya Wildlife Service. ... – Chemical/Morphometric](https://reader030.vdocuments.net/reader030/viewer/2022020413/5b928a1f09d3f23a718c07c2/html5/thumbnails/11.jpg)
Forensic methods in wildlife crime
The ouchterlony immuno diffusion methods
The precipitin method using the eletrophorensis
The DNA material analysis
- mitochondrial DNA
- nuclear DNA – micro satellites
- multilocus fingerprints
Molecular based techniques, which are highly sensitive and specific are perhaps the ultimate forensic tools to curb trade in wildlife products

Forensic PotentialSmooth surfaces –
– Fingerprints/footprints/tool marks– DNA
Absorbent surfaces – (paper/wood/cloth)– DNA– Fingerprints (ninhydrin)– Chemical/Morphometric analysis
Fluid – (Blood/saliva)– DNA– Toxicology– Spatter pattern analysis

Wildlife crime scene assessment
Identify all forensic trace evidence
Identify which will assist to investigate the offence
Preserve, recover and record the appropriate evidence
Deliver to the laboratory in a condition and with a chain of custody which allows it to be used as evidence.
![Page 14: Forensic science in illegal trade on wildlife · Forensic science in illegal trade on wildlife Moses Otiende Molecular Biologist Kenya Wildlife Service. ... – Chemical/Morphometric](https://reader030.vdocuments.net/reader030/viewer/2022020413/5b928a1f09d3f23a718c07c2/html5/thumbnails/14.jpg)
Challenges in use of forensic science in wildlife crimes
Identification of trace evidence that can assist your case by –
– Proving an offence has taken place
– Identifying an offender
– Linking an offender to a crime scene
– Linking items removed from a crime scene with that scene
In some cases no reliable methods for identification of wildlife products are
available
![Page 15: Forensic science in illegal trade on wildlife · Forensic science in illegal trade on wildlife Moses Otiende Molecular Biologist Kenya Wildlife Service. ... – Chemical/Morphometric](https://reader030.vdocuments.net/reader030/viewer/2022020413/5b928a1f09d3f23a718c07c2/html5/thumbnails/15.jpg)
Use of forensics in KWSIn the year 2002, KWS embarked on developing a forensic technique for detecting bush meat.
KWS employed the immuno-diffusion technique for wildlife meat identification. This method, developed with assistance from University of Nairobi is considered easier and less expensive
KWS collaborates with the Government Chemist to identify suspected meat samples using precipitin method.
The molecular based approach (using DNA) is yet to be used despite its complexity and cost factors

Challenges in combating wildlife crimesin Kenya
Lack of human resource
Court and litigation procedures
Weaker laws on wildlife forensics
Costs and protocols
![Page 17: Forensic science in illegal trade on wildlife · Forensic science in illegal trade on wildlife Moses Otiende Molecular Biologist Kenya Wildlife Service. ... – Chemical/Morphometric](https://reader030.vdocuments.net/reader030/viewer/2022020413/5b928a1f09d3f23a718c07c2/html5/thumbnails/17.jpg)
Conclusion (1)All standard forensic techniques are applicable
to wildlife law enforcement cases
Forensic opportunities to assist a case are many and available
Many of the techniques can be applied long after the crime has taken place so long as good crime scene preservation and recovery of evidence has been carried out

Forensic requirements in wildlife sector
Modern laboratory
Capacity building and training in forensic sciences for wildlife officers
Improved collaboration with local and international partners including INTERPOL
Appropriate policies that enhance complianceand enforcement of wildlife laws
