outsiders to visit. It saw fierce fighting during the Greek Civil War and much of the local population subsequently emigrated to escape endemic poverty and political strife. The region remained little developed until the 1970s, when it began to be promoted as a tourist destination. With an abundance of rare fauna and flora, the area was declared a Transnational Park in 2000. In 1999 the Society for the Protection of Prespa received the Ramsar Wetland Conservation Award for its conservation efforts regarding the Lake Prespa Ramsar site, and was eventually included on 3 July 2013. In 2018, Great Prespa Lake was the setting for the signing of the Prespa Agreement, intended to resolve the Macedonia naming dispute by renaming the Republic of Macedonia to North Macedonia. The agreement was signed on 17 June 2018 in a high-level ceremony at the Greek border village of Psarades on the lake, by the two foreign ministers Nikola Dimitrov (of the Republic of Macedonia) and Nikos Kotzias (of Greece) and in the presence of the respective prime ministers, Zoran Zaev and Alexis Tsipras. After the ceremony, Tsipras and Zaev crossed over the border to North Macedonia's side of the lake for lunch at the village of Oteševo, in a highly symbolic move that marked the first time a Greek prime minister ever entered the Republic of Macedonia since it declared independence in 1991. Wildlife Only 11 native fish species are known from the lake, but 9 of these are endemic: Alburnoides prespensis, Alburnus belvica, Barbus prespensis, Chondrostoma prespense, Cobitis meridionalis, Pelasgus prespensis, Rutilus prespensis, Salmo peristericus and Squalius prespensis; the additional two are Anguilla anguilla (European eel) and Cyprinus carpio (European carp). Important Bird Areas North Macedonia's part of the lake has been designated an Important Bird Area (IBA) by BirdLife International because it supports populations of ferruginous ducks, tufted ducks, Dalmatian pelicans and pygmy cormorants. The Albanian part of the lake is a separate but corresponding IBA for the same reason, as is the Greek southern section of the lake. Tourism Lake Prespa in North Macedonia has not commanded a large tourism population in the past. The majority of foreign tourism has been clustered around the sister lake, Ohrid, where there are abundant overnight accommodations, restaurants and a lively town center in the summer months. Lake Prespa has subsequently remained somewhat isolated and pastoral, bringing its own special attraction in current times. The
