The “Nida-Pērkone” protected marine territory is one of the most biologically diverse marine territories along the shore of the open part of the Baltic Sea, and it is enormously important for environmental protection. The most important reef territories are found here. During migration season, most species of migrating birds that are found in Latvia cross the area. The territory is particularly important to protect the goosander and the little gull. The territory is opposite the Rucava and Nīca administrative districts and covers 36,703 hectares. It overlaps the marine section of the Pape Nature Park and the Bernāti Nature Park.
