Mission and programs · 2024

Mission

In order to advance scientific and conservation goals Field Projects International FPI conducts tropical biology research at locations around the world. Our long-term educational programs and field courses support this mission by training the next generation of field scientists. FPI also consults for international partners in the planning and operation of field laboratories that monitor wildlife health and biodiversity.

  • Biological Research Capacity Building: Our senior scientists provide direct assistance and training in field laboratory design staffing acquisition of instruments and supplies and project development and implementation in order to expand One Health research capacity for international partners in regions of high biodiversity. These in situ labs feature genetic tools data systems and other modern technologies for wildlife population surveillance pathogen screening and toxicological investigations.

    Expenses $200,483 · Grants $212,038 · Revenue $287,545

  • Field Research Training Program: Our training programs take two forms. First we provide short intensive field courses of approximately 10-14 days in duration. Participants learn a variety of field biology research and laboratory methodologies on topics ranging from tropical biology and primatology to genomics and biodiversity monitoring. Second we organize long-term volunteer research assistantship opportunities. These programs are 5-8 weeks in duration and consist of assisting senior scientists and veterinarians at one of our field research locations. Participants gain experience with data and sample collection and analysis relating to a diverse array of flora and fauna.

    Expenses $91,944 · Revenue $99,048

  • Research: We conduct wildlife and environmental research projects for scientific and conservation impacts. Our primary research programs occur in the Peruvian Amazon where we carry out a long-term mark-recapture study of wild nonhuman primates bats birds small mammals and several other select species. Research topics range from long-term mercury bioaccumulation animal behavior and sensory perception to movement and feeding ecology.

    Expenses $115,578 · Revenue $65,235

  • Revenue from small grants allows us to support internship work in videography science communication and data system development. We also assist foreign research collaborators in the acquisition of specialty research equipment and materials that are not available to them in-country.

    Expenses $6,685 · Revenue $26,823

Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. A Schedule J breakdown is as filed: base pay, bonus, other, deferred compensation and nontaxable benefits from this organization, with any from related organizations beside each, and the filer's own total. It is shown with the Part VII listing of the same name on the same return. The form gives no key between the two, so that pairing is ours, and is marked matched by us. Earlier years are each on their own filing page.

Nonprofiteer parses Forms 990, 990-EZ and 990-PF, in a window of recent tax years. These returns are recorded from the IRS e-file index, so their figures were extracted by that index rather than read from the return here — treat them as a different source from the filings above, not as more of the same record. A dash means the index carries no figure; Form 990-T listings carry none at all.

Other IRS files

Auto-Revocation List

Not listed. The IRS publishes this list for organizations whose exemption was automatically revoked for failing to file for three consecutive years.

Publication 78

Listed as of 11 November 2026, under deductibility PC.

These are two separate IRS files on two separate schedules, shown as published and not reconciled with each other. Neither is a statement about whether a contribution is deductible today: 19,245 organizations appear in Publication 78 while the IRS's own revocation file lists them as currently revoked, more than half of those revoked before 2019. Absence from Publication 78 is evidence of nothing, and presence is not evidence either. Verify current status with the IRS before relying on it.

What this page reflects

The registration facts above come from the IRS Business Master File published 9 November 2026 and read 9 November 2026, for every organization at once. Returns through tax year 2024, the newest we have parsed for this organization.
