Restoration of the Wetlands in Palo Verde National Park: A Legal
and Ecological Analysis ramsar 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. Resources: Adair, Chris
