Using artificial canopy gaps to restore Puerto Rican Parrot (Amazona vittata) habitat in tropical timber plantations
This study tests whether or not man-made canopy gaps can restore native tree diversity as food sources for the endagered Puerto Rican Parrot (Amazona vittata). The site is located within a non-native blue mahoe (Hibiscus elatus) plantation in the Río Abajo forest in central Puerto Rico, where the researchers planted native species in assisted natural regeneration. The gaps were created in 20m x 20m plots by girdling and applying herbicide on non-native trees and by clearing leaf litter and vegetation, creating space for planted and naturally established advance regeneration seedlings.

This book, published in 1996, presents important tree species in Haiti as part of a USAID effort to address environmental degradation in Haiti. The trees presented are mainly those in the agricultural landscape, providing food or fuel, although trees with cultural or ecological importance are also presented.
Each tree profile provides information and photos including discussions of the species and common names, importance, taxonomy and botanical features, distribution and ecology, tree characteristics, utilization, propagation, and other findings (biomass studies, growth performance, tree improvement, seed research, and/or planting stock quality).
