  • Area of expertise
      Wildlife Incident Investigation Scheme (WIIS)
  • Years of experience
  • Highest qualification

The WIIS has two objectives:

  • To provide information to the regulator on hazards to wildlife and companion animals and beneficial invertebrates from pesticides; and
  • To enforce the correct use of pesticides, identifying and penalising those who deliberately or recklessly misuse and abuse pesticides.

The WIIS relies on members of the public and individuals from other organisations to find and report the death or illness of wildlife, pets and beneficial invertebrates that may have resulted from pesticide poisoning.

Libby represents WIIS for England and Wales in the WILDCOMS network and has presented results of WIIS at UK and international fora and conferences.

More about WIIS

The Wildlife Incident Unit (WIU) plays a key role in investigating the effects of pesticides on animals and the environment, through its contribution to the Wildlife Incident Investigation Scheme (WIIS).
