Washington Slagbaai National Park  Washington Slagbaai National Park is a national park and ecological reserve on the northwestern part of the island of Bonaire in the Caribbean Netherlands. The park covering approximately a fifth of the island of Bonaire is managed by STINAPA Bonaire, a non-profit foundation, on behalf of the Bonaire government. Established in 1969, Washington Slagbaai National Park was the first nature reserve to be established in the former Netherlands Antilles. The flora includes about 340 species. Many of the plant families (about 40%) are represented by only one species. Typical vegetation is made up of low thorny scrub ("") and two main species of cacti: the yatu ("") and the cadushi (in Wayuunaiki) or kadushi (""). Park seashores are nesting ground for endangered sea turtles: the Green Turtle (""), the Hawksbill ("") and the Loggerhead sea turtle (""). On rare occasions one can see Leatherback sea turtles (""). The park is also an Important Bird Area (IBA) since it serves as nesting, roosting, and foraging area for endangered or restricted-range bird species. The salt pans are a special area and home to the Caribbean Flamingo (""), the "Pekelmeer flamingo sanctuary"
