Forensic science in ille g al trade on wildlife

1. Forensic science in illegal trade on wildlife Dr Richard K BagineKenya Wildlife Service

2. Presentation outline • Introduction • Illegal trade in wildlife • Wildlife crimes in Kenya • Forensic in wildlife and their potentials • Challenges in use of forensic science • Use of forensics in KWS • Conclusion

3. 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

4. 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 have declined in recent years as a result of trade in their products.

5. Introduction cont’d… • Other wildlife species also declining due to continued degradation of habitats and unsustainable use of their products

6. Illegal trade in wildlife(1) The factors contributing to illegal trade in wildlife and 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

7. 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 crime scene?

8. 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

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

10. TROPHY POACHING OF WILDLIFE • Target Trophies • Ivory • Rhino horns • Skins • Corals and shells

11. SOME STATISTICS - ARRESTS AND RECOVERIES (2005)

12. Forensicsin 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

13. 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

14. Forensic Potential • Smooth 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

15. Potential strength of evidence using forensic methods

16. 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.

17. 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

18. Use of forensics in KWS In 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

19. Challenges in combating wildlife crimes in Kenya • Lack of human resource • Court and litigation procedures • Weaker laws on wildlife forensics • Costs and protocols

20. 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

21. Conclusion (2) 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

22. THANK YOU

23. SOME THREATENED/ENDANGERED SPECIES

24. What are you looking to identify? • Anything which does not belong to the scene • Anything which has been disturbed or damaged • Anything which has been removed • Any part of something which has been removed or has been left behind • Anything left at the scene by the offender • Marks made at the scene by the offender

25. Basic handling and contamination avoidance • Four Key Areas – • PPE – (Personal Protective Equipment) • Activities at the scene • Sample Collection/taking • Transportation and packaging
