Mount Isarog is a potentially active stratovolcano located in the province of Camarines Sur, Philippines, on the island of Luzon. It has an elevation of 2,000 metres above mean sea level.
The peak of the mountain marks the point where the borders of five municipalities and one city meet (listed in clockwise direction, starting north): Goa, Tigaon, Ocampo, Pili, Naga City, and Calabanga.
Mount Isarog was where local troops of the Philippine Army and Constabulary units and Bicolano guerrillas hid during the Japanese Period. In the 1970s, with the leadership of Romulo Jallores and his brother, they established the New People's Army in the Bicol region at the foot of this mountain.
It was made a public land through the Proclamation No. 157 on March 28, 2015. Towns around it is classified as timberland forest with an area of 13,433 hectares (33,190 acres).
On August 17, 1935, General Frank Murphy established the Mt. Isarog Forest Reserve which reduced the size of the area to 10,112. But it was revoked by President Manuel L. Quezon when he signed Proclamation No. 293 titled "Establishment of Mt. Isarog as a National Park."
On June 1, 1992, with the passage of Republic Act 7586 known as the National Integrated Protected Areas System or NIPAS, Mt. Isarog was National Integrated Protected Area Programme. On June 20, 2002, by virtue of Proclamation No. 214, Mt. Isarog became a protected area under the natural park.
Mt. Isarog has a rich diversity. It displays four major types of natural habitat or vegetation; from the warm grassland and lowland forest to the wet and cool climate of montane forest.
The lowland forest is noted for its tall canopy. The uppermost layer towers between 30–40 meters and sometimes even reach 60 meters. Many of these trees belong to the dipterocarp family. The second canopy layer (between 23–30 meters) has the sustain bamboos (Bambusa), arborescent palms (Calamus), climbing bammboo (Schizostacyum), climbing pandans (Freycinetia) and vascular epiphytes such as orchids and ferns.
