How to Apply
Round 12 is now open!
Introduction
The Illegal Wildlife Trade (IWT) Challenge Fund is a UK government grants scheme that provides support to innovative and scalable projects to reduce pressure on wildlife from illegal trade and wider environmental crime and, in doing so, reduce poverty in developing countries.
Please note all IWT Challenge Fund projects should address one, or more, of the following themes:
- Reduce demand for IWT products and other environmental crime products
- Ensure effective legal frameworks and deterrents
- Strengthen law enforcement
- Develop sustainable livelihoods to benefit people directly affected by IWT and wider environmental crime
The guidance documents for each scheme can be found below. All applications should be submitted via the Flexi-Grant application portal.

To ensure UK funding remains responsive to this evolving landscape, Round 12 will trial a revised approach within the Evidence scheme, which will explicitly support evidence generation on a broader range of environmental crimes. IWT Challenge Fund Main and Extra scheme projects will retain a primary focus on IWT in Round 12.
IWT and environmental crime definitions
- Illegal Wildlife Trade: The IWT Challenge Fund defines IWT as all unlawful activities associated with the commercial exploitation and trade of wildlife, including live organisms, their parts or derivatives. This includes all wild fauna, flora, and fungi and so covers illegal trade in timber and fisheries products within this definition.
- Environmental crime: includes illegal activities that harm nature and the sustainable use of natural resources, including IWT, illegal logging, fisheries crime, illegal mining, and waste crime.
Once you have read the guidance, you will be required to complete additional material as part of your application, which can be found on the respective scheme pages found in the side menu, or downloaded from Flexi-Grant.
All applications should be submitted via the Flexi-Grant application portal.
