The development of this Web site was supported, in part, by a grant from the Société Audubon Haïti. The initial collections made in the Macaya park were funded by USAID (project no. 521-0191-A-00-7107-00, to Charles Woods) and later fieldwork was supported, at least in part, by a number of National Science Foundation grants, especially BSR-9016793, BSR-8406760, BSR-85-14299, DEB-0818399, and DEB-0515636, with various P.I.s.
