Mission and programs · 2023
Mission
To ensure the survival of sea turtles within the wider Caribbean basin and Atlantic through research, education, training, advocacy, and protection of the natural habitats upon which they depend.
-
Florida Programs Networking, education, advocacy, research, and grants programs based in the United States to eliminate threats facing sea turtles and to preserve nesting and feeding habitats. This includes an in-water research project to study the sea turtles of the Big Bend region of Florida. Other activities include close monitoring and shaping of policies at the local and state level impacting sea turtles and their habitat. STC also hosts Tour de Turtles, an annual educational program using satellite-tracked migrations of sea turtles that combines research and education into a free, interactive program available online to anyone.
Expenses $1,184,931 · Grants $538,717
-
Lighting and Predation - Initially these programs were created in response to the Deepwater Horizon oil spill in the Gulf of Mexico. Funds have been used for sea turtle mitigation in three areas: lighting, rehabilitation, and predation. Currently funding continues for mitigation in lighting and predation. Lighting grants replace problem fixtures on coastal properties with shielded amber LED lights that reduce disorientation for nesting turtles and hatchlings. Predation funds concentrate on reducing the incidence of predation of turtle eggs and hatchlings.
Expenses $921,561 · Grants $434,340
-
Tortuguero Research and Conservation - Sea turtle research and conservation based in Tortuguero, Costa Rica. Emphasis is centered on the local populations of green and leatherback turtles. This includes tagging and educational activities, research grants, fellowships, and other related expenses. The project also includes a research assistantship program that provides training to aspiring biologists, particularly from Latin America and the Caribbean.
Expenses $760,683 · Grants $336 · Revenue $134,979
-
Panama Research and Conservation - A collaborative sea turtle research and conservation initiative based at Bocas del Toro on Panamas north Caribbean coast. Modeled after STCs Tortuguero program, the purpose of the Panama project is to study, protect and recover local populations of leatherback and hawksbill turtles, both of which nest in globally significant numbers in the region. The project includes ongoing monitoring, protection and education activities at Chiriqui Beach, Playa Larga, Red Beach and Escudo de Veraguas, Soropta, Colon, Bluff Beach and the Zapatilla Cays.
Expenses $624,649 · Grants $1,454 · Revenue $300,000

The BIC provides a focal point for the Refuge and the associated barrier island by providing exhibit space, a presentation hall and ongoing educational programs that promote stewardship of the areas fragile natural resources. Through a partnership with the Brevard County Environmentally Endangered Lands Program, STC oversees and conducts the educational programs offered at the BIC, and manages a small gift shop.

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 13 October 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.
