The local government units, DENR and the SINP-PAMB have been exerting all its efforts towards this bid. Recently, tourism officers from different municipalities within the province of Samar, Eastern Samar, and Northern Samar convened for a workshop on the preprartion of SINP's nomination dossier.

"The dossier will serve as a compilation of all documents that will showcase SINP's outstanding universal value. This is necessary for the assessment and evaluation of the SINP by the UNESCO," Samar PENRO Angelito Villanueva says.

“The realization of SINP’s inclusion to UNESCO World Heritage List will bring honor not only to the whole Samar island but also to our country. SINP will be given global significance in terms of development and protection of its rich natural and cultural value,” he added.
