The Vermont Institute for Natural Science (VINS) has made several trips to the Pic Macaya in recent years to capture, tag, and document birds there. This 2006 brief, but very informative, report (with a couple of nice photos) is worth a look (a longer and much more technical report from 2004 is also available). It sounds as if plans exist to help protect both of Haiti’s national forests and some part of future international funds should, I feel, go towards this goal. This 2007 report by VINS indicates that interest in the government is present. They also found that the local population had an interest (although they gave no specific details):
Locally, a conservation ethic appears to be present, but acknowledgment of Macaya's importance is constrained by the day-to-day struggle of its people to survive. No one harbors illusions that long-term conservation must entail significant socioeconomic changes for the local population. We batted around many ideas of how that might happen, but it is clear that a significant international commitment of resources will be needed. The situation is tenuous, but far from hopeless.

I lived for several weeks in Jeremie and went up into the mountains one day on a mule. The greenery and fog up in those mountains are truly amazing.
Haiti’s other national forest, La Visite in the southeast, is also home to some endangered bird species (see page four of that VINS report).
