Applications must have been received by 5 p.m. US Central Time on 31 October, 2023


  • Large-tier grants provide up to $25,000 over 1–2 years.
  • Please note that large-tier grants will not be awarded in the 2023 cycle.
  • Small-tier grants provide up to $10,000 over 1 year.
  • Full proposals for small-tier grants in the 2023 cycle are due by 31 October, 2023.


For 2023, please be aware that a very limited number of grants will be awarded, up to a maximum total of $40,000 overall. Only small-tier proposals will be considered (up to $10,000), and we hope to see substantial matching funds. Preference will be given to long-term projects that are most in need and with a history of support from the IIF. However, we do not want to discourage innovative or urgent projects, so if you have a compelling proposal and are uncertain if you should apply, please contact Dr. Pasachnik to discuss further.

The International Iguana Foundation grant awards were established to promote and enable iguana conservation through partnerships with scientists, educators, and organizations committed to preserving Earth’s biodiversity.

The IIF seeks to provide annual project funding to a wide range of species and programs through our grant application process. A Request for Proposals is typically announced in mid-summer and granting decisions are made by the IIF Board of Directors in October–December.

Preference will be given to:

  • Projects that directly contribute to the survival of Critically Endangered and Endangered iguanas and their habitats.
  • Projects that help to gain information on Data Deficient iguana species and update the associated IUCN Red List.
  • Projects that are included in the IUCN SSC Iguana Specialist Group’s Conservation Action Plans, are ISG-endorsed, and/or are approved regional action plans.

Criteria the IIF uses to evaluate project proposals:

  • The project has range country participation and has matching funds.
  • The project builds on previous work, contributing to an established commitment to a conservation program, or is well suited to become/contribute to a long-term conservation program.
  • The project is grounded in sound scientific methodology, is logistically feasible, and has a high probability of success.
  • The project has conservation value and a measurable impact.

Emergency Funding:

Conservation emergency funding may be considered, outside of the normal application period, on a case-by-case basis, at the discretion of the IIF Board of Directors. Contact Dr. Pasachnik for details.
