The Palo Verde National Park wetland, one of Central American’s largest, was considered an ecosystem worthy of recognition when Costa Rica ratified the Ramsar Convention on Wetlands of International Importance in 1991. In recent decades, however, significant ecological changes caused by an invasion of the emergent aquatic plant known as cattail (typha) occurred within Palo Verde, resulting in a significant decrease in the number of migratory waterfowl that nest within it. This decline in wetland quality caused Palo Verde to be added to the list of internationally threatened wetlands under the Ramsar Convention in 1993. The overarching objective of this practicum was to identify how the health of Palo Verde could be restored to the point that its removal from the Montreux list would be warranted.
