Community environmental preservation initiatives in Borgne, Haiti

The purpose of this thesis was to complete an analysis of the work and practices of the community organizations of Borgne, Haiti. While the work of several community organizations were examined, research specifically focused on the community’s tree-planting project. Given the current state of Haiti’s environment and the historic record of development efforts in Haiti, this project represents a unique model that may have larger implications on the way in trees are planted throughout Haiti. Field research was completed on site in Borgne in the summer months of 2010. The primary methods employed in data collection were Participatory Action Research and semi-structured interviewing.

Using Florida Keys Reference Sites As a Standard for Restoration of Forest Structure in Everglades Tree Islands

In south Florida, tropical hardwood forests (hammocks) occur in Everglades tree islands and as more extensive forests in coastal settings in the nearby Florida Keys. Keys hammocks have been less disturbed by humans, and many qualify as “old-growth,” while Everglades hammocks have received much heavier use. With improvement of tree island condition an important element in Everglades restoration efforts, we examined stand structure in 23 Keys hammocks and 69 Everglades tree islands. Based on Stand Density Index and tree diameter distributions, many Everglades hammocks were characterized by low stocking and under-representation in the smaller size classes. In contrast, most Keys forests had the dense canopies and open understories usually associated with old-growth hardwood hammocks. Subject to the same caveats that apply to off-site references elsewhere, structural information from mature Keys hammocks can be helpful in planning and implementing forest restoration in Everglades tree islands. In many of these islands, such restoration might involve supplementing tree stocking by planting native trees to produce more complete site utilization and a more open understory.
