GDFCF promotes the long term survival of ecosystems and biodiversity of Area de Conservacion Guanacaste through conservation, education, science-based management, and biodiversity development.  We support a globally-significant example of tropical forest restoration and conservation.

  • Bioliteracy for everyone

    GDFCF provides transparent and science-based knowledge for users of exceptionally diverse tropical wildlands that includes schoolchildren, local residents, and the international community.  We promote our wildlands management style with conservation and restoration efforts worldwide.

  • Research throughout

    Science-based understanding of ACG's forest and marine ecosystems are conducted by local resident career "parataxonomists" in collaboration with national and international science networks.  For 34 years, ACG has worked to restore nature though involvement of neighboring communities to ensure its survival. GDFCF and its founders have been a major dance partner in the evolution of this conservation restoration model.

  • Área de Conservación Guanacaste

    With GDFCF support, ACG:

    • includes ~375,000 species of which less than 1/3 are known to science
    • contains 2.4% of total global biodiversity
    • contains > 60% of Costa Rican biodiversity
    • consists of only 2% of the land base of Costa Rica
    • covers 165,000 hectares, or about 408,000 acres (by comparison Great Smoky National Park in U.S. is 521,000 acres)
    • is a globally recognized UN World Heritage Site

  • Where We Work

    We work in a place of outstanding biodiversity and beauty in northwest Costa Rica called Area de Conservacion Guanacaste (ACG). Home to 2.4% of the world’s terrestrial biodiversity, the ACG is the only protected area in the Neotropics that sweeps from Pacific Ocean waters up over the volcanic mountain range of the continental divide and down into the lowlands of the Atlantic rain forest. The Guanacaste Dry Forest Conservation Fund (GDFCF) was formed to aid with the development, protection, and sustainability of ACG.
