The first important legislation that formed the basis of the current system of national parks and protected areas in the Philippines is Act No. 648, enacted in 1903 by the
Philippine Commission. This act authorized the
civil governor to "reserve for civil public purposes, and from sale or settlement, any part of the public domain not appropriated by law for special public purposes." A total of eight national reserves had been established on July 26, 1904, pursuant to this law. These are the Lamao Forest Reserve in
Bataan,
Mariquina Reserve in
Rizal,
Angat River Reserve in
Bulacan,
Caliraya Falls Reserve in
Laguna, La Carlota Reserve in
Negros Occidental, San Ramon Reserve in
Zamboanga, Magalang Reserve in
Pampanga, and Hacienda San Antonio in
Isabela. In the same year, the Forest Act of 1904 (
Act No. 1148) was adopted that expanded the scope of protected areas in the Philippines. Among the first of such mountain forest reserves to be declared was
Mount Maquiling declared on November 21, 1910. On February 1, 1932, the National Parks Act (
Act No. 3195) was enacted that formally established the national parks system in the country.
Mount Arayat became the first national park in the Philippines established on June 27, 1933, following this act. A series of acts and legislations were passed in the next decades that aimed to further strengthen these policies, including the Revised Forestry Code of 1975 (
Presidential Decree No. 705) and Forest Administrative Order No. 7. Following the
1987 Constitution, the National Integrated Protected Areas System Act was enacted which further enhanced the administration and classification of protected areas and broadened the mandate of the
Department of Environment and Natural Resources in enforcing its provisions. == Classification ==
