The World Heritage Centre currently receives numerous messages from civil society concerning the state of conservation of the World Heritage property Pirin National Park. The competent authorities of the Republic of Bulgaria as well as the World Heritage Centre and the Advisory Body IUCN are fully informed of the concerns raised.

At its 40th session in 2016, the World Heritage Committee called on "the State Party to invite in 2017 an IUCN Advisory mission to review the implementation of the Management Plan and the preservation of the OUV of the property" (Decision 40 COM 7B.93). The Bulgarian authorities and IUCN are currently preparing this mission, which is expected to take place in the coming weeks. The results of the IUCN Advisory mission will be reported back to the World Heritage Committee at its 42nd session (Manama, Bahrain, 24 June to 4 July 2018).

Furthermore, the World Heritage Committee has requested the State Party "to submit to the World Heritage Centre, by 1 December 2017, an updated report on the state of conservation of the property and the implementation of the above, for examination by the World Heritage Committee at its 42nd session in 2018" (Decision 40 COM 7B.93). This report and all other relevant documents are available at http://whc.unesco.org/en/list/225/documents/.
