We publish our audit record because accuracy claims should be checkable. Every entry on this site runs through an automated fact-audit pipeline (accuracy audit → source-grounded repair → visual QA); this page is generated from that pipeline's own report, not written by hand.

Aurora Memorial National Park — The park's length along the Bongabon-Baler road is approximately 30 kilometers, not 50.
Aurora Memorial National Park — The maximum altitude in the park is around 1,200 meters, not 1,000 meters.
Balbalasang–Balbalan National Park — The park was established in 1972 under Republic Act No. 6463, but the correct legal basis is Proclamation No. 1083, series of 1972.
Balbalasang–Balbalan National Park — The highest peak is listed as Mount Sapocoy at 2,456 m, but the actual highest point in the park is Mount Balbalasang, with an elevation of approximately 2,456 m.
Bataan National Park — The park's initial area of 31,000 hectares included parts of the fenced area of the Subic Bay Freeport Zone, but the Subic Bay Freeport Zone did not exist in 1945; it was established in 1992.
Biak-na-Bato National Park — Trinidad Tecson was not born within the boundaries of Biak-na-Bato National Park; she was born in San Miguel, Bulacan, which is a municipality that contains the park, but the park itself is a specific protected area, not the entire municipality.
Casecnan Protected Landscape — The entry states the Casecnan Protected Landscape was designated a national park on June 22, 2018, but it was reclassified as a protected landscape under the ENIPAS Act, not a national park.
Hundred Islands National Park — The claim that Hundred Islands National Park is 'the first national park established in the Philippines' is incorrect. The first national park was Mount Makiling National Park, established on February 23, 1933.
Mount Arayat — The claim that Mount Arayat was declared a tourist spot in 1997 is incorrect; it was declared a national park in 1933, and no widely known official declaration as a 'tourist spot' in 1997 exists.
Mount Arayat — The statement that 'an analysis report indicates the volcano erupted over the last 2,000 years' is misleading; PHIVOLCS classifies it as potentially active but there are no confirmed historical eruptions within the last 2,000 years.
Mount Data — The Agno River does not originate from Mount Data; its headwaters are in Mount Pulag, not Mount Data.
Mount Data — The claim that Carpomys melanurus was first found on Mount Data in 1896 is inconsistent with the LORE section stating it was collected during John Whitehead's 1895 expedition; the correct year is 1895, not 1896.
